Tweak your Instagram vids beyond what you can achieve in the app. In this post we share a more powerful workflow for editing your Instagram videos.**We’ve updated this article! See the in-depth guide to uploading 60-second videos to Instagram.Since adding video to its service in the summer of 2013, sharing video through Instagram has grown from a simple photo app to a powerful way of showing off your videos to a growing network of friends and users. With these steps you can import your best 15 seconds for the world to see.1. The rules of Instagram are made simple: 15 seconds of video in a 1:1 square ratio. First, bring your video into an editing application and cut at will. Most video editing applications allow you to modify the aspect ratio of your project.Instagram video dimensions are 640X640.If you don’t know how to do this, Instagram will automatically crop the sides of the video upon import and let you tweak the cropping point within the app, but if you want to double check the crop points before putting it onto your phone do it here or within the encoding process.2. Next, you will want to get your video into the H.264 codec. This format is ideal because it looks great while still keeping your file size low (to make transferring your video quick and painless). Instagram will accept other video formats, this is just the smoothest one I have found.I use Compressor with the H.264 setting, but other encoding apps will also convert to H.264 (like Adobe Media Encoder or the free MPEG Streamclip app).3. Once the video is in the right format, the easiest way I have found to get a video from your desktop to your phone is by using the Dropbox app with a free account. If you aren’t familiar with Dropbox, it’s a cloud storage company that offers limited amount of space for free users but more than enough than we need for this project. Sign up and download here. 4. After you have uploaded your video to the Dropbox folder on your computer. Then, install the app on to your phone, find your video file within the app and save it to your camera roll or gallery. Here you can you access it from Instagram. Now share your creation with the world.Got your own tricks for editing and exporting video for Instagram?

Lens Construction6/7 Groups It’s no secret that photography and filmmaking is an expensive industry, so any opportunity to save a little money on quality is well received by consumers. This may shed some light on a shift in the gear industry…There will always be a demand for cheap equipment, but if more entry-level people begin purchasing less expensive ‘knockoff’ lenses, name-brand manufacturers may be forced to make lenses cheaper, effectively compromising quality for price.We’re going to be interested to see the quality of this lens. We are clearly not expecting it to be as good as the Canon 50mm, but eagerly await user tests.As of right now Yongnuo has not released a price or a release date for the 50mm f/1.4 lens. However, considering the price of the Canon is $400, we can probably expect to see the Yongnuo 50mm priced below $300.Is this lens going to be a good alternative to the Canon 50mm f1.4? Share your thoughts in the comments below. Aperture Blades8 Drive SystemDC motor Focal Length50mm Closest Focusing Distance0.45 m Filter Diameter58mm If you can’t beat ’em, create an exact copy and sell it for less?As far as Chinese knockoffs go Yongnuo is about as good as it gets. We’ve had some experience with shooting with a Yongnuo Speedlight and for the price you aren’t really going to find a better deal. Youngnuo products are primarily geared around lighting for photography. However, a recent announcement affirms that Yongnuo is expanding it’s product line by getting into the lens manufacturing business.One of these is a Canon Lens and the other is Yongnuo. Can you tell which one?Yongnuo has announced a 50mm f/1.4 that fits Canon EF lens mounts. The lens is a shameless ripoff of the similar Canon lens, but the specs are still pretty darn good. Most notably this cheap lens has 8 aperture blades making it a near replica of the Canon 50mm 1.4. The biggest difference comes in the form of the autofocus. The Canon has a patented Ultrasonic motor but the Yongnuo has a DC motor, so this might be a potential weak point in the Yongnuo lens. Here’s the rest of the specs:Yongnuo 50mm f/1.4 AF Lens Aperture Rangef/1.4-22
GoPro is going airborne. New GoPro drone product to be announced at the 2015 Consumer Electronics Show.GoPro plans to dive into the consumer drone market and launch it’s own drone line sometime in 2015. It was recently announced that GoPro would present their newest product at the J.P. Morgan Tech Forum at CES 2015 on Jan. 6th in Las Vegas. Initial reports state the new GoPro drone will retail for between $500 – $1000.Early indications suggest this is a multi-rotor drone possibly similar to the Chinese DJI S1000. GoPro drives significant revenue from the sale of their accessories, so entry into this product category seems like a logical step for the company to take.DJI’s dual operator Inspire drone [click for larger view]: Surely, GoPro’s launch into the burgeoning consumer drone market will effect other players in the space. DJI recently launched a drone product with it’s own camera (the Inspire), but GoPro’s dominance in both the consumer and professional video production markets may make it extremely difficult for others to compete.Is it a winner takes all consumer drone market? We’re curious to see.What are your thoughts on GoPros expected debut into the drone marketplace? Share in the comments below.
Here are some tips for giving constructive feedback to editors that will keep everyone’s workflows healthy and productive.Recently, we covered how working with an assistant editor can be a helpful way to streamline your video projects. Today, we’ll take it a step further and look into how to give solid (yet constructive) feedback to your partners or assistant editors to create a healthy, productive, and fun workflow.Image via KORNBURUT WORADEE.1. Consolidate FeedbackHaving worked as a video editor on projects big and small, this was probably my number one pet peeve every single time. You make an edit, send it over for revisions, and get some comments back. No big deal. They seem fine, so you jump into the edit and make the changes. Then as you’re exporting a new version, you see another email come in with a whole new set of contradictory requests. It’s the worst!Save yourself and your editing partner these headaches and make sure your feedback is 100 percent consolidated and contains all the necessary information. If you need to show a draft to several parties, don’t reply with your edit requests until every party has responded.Once you have a comprehensive breakdown of the feedback, it’s your job to consolidate it before passing it over to your editor(s). If there’s conflicting or contradictory feedback, resolve the issue before sending it on.Don’t say: “Actually here’s one more list of changes . . .”2. Focus on the PositivesYes, we’re all adults in this industry, and we can act professionally, but that’s no reason not to be nice, positive, and supportive as much as possible. If an editor has worked hard and done a great job, let them know and thank them. Before you give any constructive feedback on things to change, find a few of the best parts and highlight those. Giving good positive feedback on the best parts can actually be more constructive in the long run, as it exemplifies what you’re really looking for.Don’t say: “This is pretty bad. I’d change all of the following . . .”3. Present Opportunities to ImproveIn editing, much like in filmmaking (or any other art), there are no right or wrong choices; rather, there are creative decisions you must make at every stage of the edit. As such, saying something is “wrong” is simply an incorrect way of thinking. Instead, if you can focus on areas that don’t feel as strong as others, your feedback becomes an opportunity to improve the overall quality of project.Don’t say: “That first section is just wrong; that’s not the right first shot . . .”4. Be PreciseThat being said, while it’s important to stay positive, you also need to be precise. If a section feels off to you, try to really detail what about it is causing you concern and give pointed examples or insights into what would be the best way to fix the issue. Give concrete examples.This is where using collaborative review platforms like Frame.io can be really helpful — you can leave feedback at exact frame marks and make recommendations for changes directly.Don’t say: “I just think we need something else there, you know . . .”5. Don’t Leave Things Open-EndedFinally, the last thing you want to do in any of your feedback is to throw the ball back into your editor’s court and leave things open-ended regarding how to wrap things up. If your editor is helping you finish your video project, they need you to share your vision with them. Ideally, unless several other parties are involved, you should only go through one (or two at most) rounds of revisions.Therefore, it’s very important to leave consolidated, positive, and concise feedback that clearly defines what should happen next — and a deadline by which to finish to finish the project.Don’t say: “We’ll figure out everything else later on when finishing this up . . .”Cover image via recklessstudios.For more video editing advice, tips and resources, check out these articles below.How to Change the Color of Exterior Lights in After EffectsVideo Tutorial: Harness the Power of Presets in Adobe After EffectsRoundup: The Best Portable Hard Drives for Video EditingChanging the Audio Editing Game with PremiumBeat’s Track StemsHow to Create the VHS Look in Premiere Pro + Free VHS Effect Presets

New apps and social platform make it nearly impossible to keep up with all the opportunities to promote what you have to sell. Jill Rowley has been in the sales arena for a long time and her experience includes some of the first online ventures. She’s seen the way salespeople have become marketers and how the lines are being blurred. In this conversation she talks with Anthony about sales curiosity, helping prospects make changes to adapt to your solution, nurture sequences for prospects and customers, and how salespeople can stand out in the noisy social world. It’s a packed conversation you’re really going to enjoy.Using social to build meaningful relationships that fuel the sales funnel, on this episodeClick To TweetHow curiosity helps the prospecting and sales process.Jill Rowley is a naturally curious individual and with a background and education in business she’s become naturally curious about the way businesses work and turn a profit. On this episode of In The Arena you’re going to hear how her curiosity about businesses and their owners points her toward intelligent and revealing questions that fuel her prospecting and sales process. You’ll also get an earful of advice about how you can begin to think about the prospecting puzzle that will help you build trust based relationships rather than “sale based” pitches. You’re going to benefit greatly from this one.Are you helping your sales prospects make the changes needed to adopt your solution?Many sales professionals don’t recognize that in order for a prospect to take on your solution for their problem, they and their company are going to have to make some changes. Sometimes those are small changes and many times they are rather large. On this episode Jill Rowley shares how she goes about helping her prospects make the changes need to adopt her solutions and tells how that extra step has helped her close more and more sales and build long term relationships.I want to understand the company that will hopefully become my customer ~ Jill RowleyClick To TweetWhat goes into an effective nurture sequence for prospects or clients?Jill Rowley was on the forefront of developing nurture sequences when she worked in sales back in the early stages of the internet’s development. But she didn’t use emails and autoresponders. She used paper printouts of articles and brochures, hats and T-shirts, and postal mail. Nobody told her to do it, she intuitively knew that she needed to build the level of trust her prospects and customers felt toward her and wanted to be useful to them in order to facilitate that process. If you’re a sales professional you’ve got to do the same thing. Find out how Jill advises you go about it, on this episode.How sales professionals can stand out in the noisy social media world.The saying, “Content is King” used to mean something, but now that the social media world has gotten to be so noisy, it’s no longer about content first – it’s about being noticed. It doesn’t matter if you create incredible content if nobody is able to see it through the noise and hustle of a busy social media feed. Jill Rowley has taken a different approach by using social media to find the individuals who need the solutions she has to offer and doing what she can to connect with them on more personal levels. With all genuineness she interacts, reshares, tweets, and makes conversation with them and their social circles. When the time comes for the pitch, she’s laid a foundation of familiarity that often translates into rapid trust.

Almost every day I drive through the Starbucks in my neighborhood. Most days the team that works at this particular Starbucks does an exceptionally good job managing high traffic. On days when someone is missing, the traffic backs up. Traffic is particularly backed up at the drive-through window. Because the Starbucks is located in suburbia, there might be 20 cars waiting to order a drink.But some days, when there is a new team, even the large staff can’t manage the traffic. It isn’t because they’re not good people, and it isn’t because they don’t care about their work. They just are not clicking well together. They don’t have a rhythm. They can’t anticipate what customers need or how best to help each other.And this is the nature of teams. When people have the right chemistry, when they’ve worked together and know how to work as a single unit, they are highly effective and highly efficient. But a team that doesn’t have the right chemistry, that hasn’t spent time learning how to work as a team can be inefficient and ineffective–even though individually each member of the team is perfectly competent.In fact, changing just one member of an effective team can have a detrimental impact on the team’s effectiveness and efficiency. Even if that one individual should be, by all accounts, perfectly qualified to generate the outcomes necessary to perform on that team.Time: For a team to gel together the members need time. Sometimes you can be lucky enough for someone to step in and immediately fit with the team, but more often it’s a matter of spending time as part of the team.Communication: For a team to work well together, there needs to be exceptional communication. After a team has worked together, they don’t need to communicate as frequently or with great direction, because they know how each other thinks. In fact, they think as a team. But that competency was only developed because there was so much communication at some point. But the new member wasn’t there when the team learned to work together, and now the new member needs that same communication to succeed.Expectations: A new team member needs to know what that team expects of them to be effective. They need to know what good looks like. The team has a standard, and a new person on that team will not be familiar with that standard. The team has to teach the new member.It takes time for a group to become a team. It takes time and communication. That is how teams work.
You are competing for a prospective client’s business. You know there are two other companies being considered, both of whom, like you, could do good work were they awarded the business. You have all done discovery, developed a solution and presented your final proposal.Your CRM has a pull-down menu that indicates the stage of the sales process, as well as the likelihood of winning that deal expressed as a percentage. Your CRM suggests that you have a 75 percent chance of winning this deal. Your two competitors also have CRMs, and their likelihood of winning based on the stage is also 75 percent. Neither you nor your competitors have a 75 percent chance of winning the deal at this point.If there are three competitors in this contest, none of whom have been ruled out for some reason, the very highest odds you have in winning is 33 percent. One company will win, the other two will lose, as is the nature of a zero-sum game. The 33 percent chance is the very highest number you can use to project your chances, and the number could be 25 percent, leaving open the possibility that the client decides not to do anything, something that happens frequently in sales.If there are only two competitors in this same competition, the best you can guess (and you are guessing, unless you have strong evidence that suggests otherwise), is a 50 percent chance of winning, with the real number being 33 percent, again leaving open the option to do nothing.If there is one thing that hurts sales organizations, sales leaders, sales managers, and salespeople, it’s the false confidence that comes from believing they have enough opportunities to meet and exceed their goals. Much of the time, when they are surprised, the surprise comes in the form lost deals they believed they would win, deals that ended in a no-decision, and deals they believed they would win that push into future quarters because the date in the CRM is, was, and always will be a placeholder when it lacks a client’s commitment.If you are going to use a percentage to express your likelihood of winning, you are better off with a rule of thumb that suggests that three competitors in a deal means you have a 33 percent chance of winning and not 75 percent.
Odisha’s Forest and Environment Minister Bikram Keshari Arukha informed the State Assembly on Tuesday that 5.97 lakh trees had been felled in the last six years to make way for the construction and widening of roads. Mr. Arukha, however, claimed that forest cover in the State has gone up by 25% in the past decade.Paying a heavy environmental price for development, it was revealed that the Odisha Forest Development Corporation cut down the trees for 437 road projects across the State. The current fiscal year has been the most devastating for forest cover in Odisha: of the 5,97,090 trees felled since 2011-12, 3,15,838 were cut down in 2016-17.Worst hit Keonjhar district has been the worst hit with 94,996 trees felled — 20% of total trees lost — in the past three years for 23 road projects. In 2016-17 alone, Keonjhar lost 76,439 trees while Kalahandi district lost 62,959 trees.Other affected districts include Sundargarh, Sambalpur, Bolangir, Jharsuguda and Jajpur.Although the Odisha government claims to have planted 1.65 crore trees along 24.57 lakh km of roads in the past decade, the chances of the trees surviving is doubtful. In 2016-17, avenue plantation was taken up along 5,462 km of roads, said Mr. Arukha. New variety“The loss cannot be compensated. Thousands of trees felled for road projects in Keonjhar and Kalahandi were over 70 years old. Mature fruit-bearing trees were sustaining wildlife. The trees planted now are of the exotic and fast-growing variety,” said Biswajit Mohanty, environmentalist and former member of the National Board for Wildlife.Trans-location“The State government never thought of trans-locating trees while taking up road projects. In Puducherry and Tamil Nadu, trees are uprooted and replanted at another place. Had translocation been done here, we could have saved 60% of the trees,” said Mr. Mohanty.The loss of green cover to road projects is just the tip of the iceberg. As many as three lakh trees were felled as part of the land acquisition process undertaken for the shelved POSCO mega-steel project near Paradip town four years ago. While 2.25 lakh of the felled trees came under the forest-classified category, 75,000 were fruit-bearing species.The residents of Rajkanika in Kendrapara district had opposed the felling of trees for the Cuttack-Chandbali road project. “Trees from the colonial era were cut down. When NH authorities decided to fell trees, we opposed it. But nobody paid heed to us. These losses cannot be compensated,” said Gayadhar Dhal, a resident of Rajkanik
An undertrial prisoner hailing from Jharkhand has escaped from the MKCG Medical College and Hospital premises in Berhampur, where he was undergoing treatment.Sub-Divisional Police Officer of Berhampur Santanu Kumar Dash told the media on Friday that Manoj Singh escaped on Thursday and he has not been traced till now. The police have launched a manhunt for him.According to police, Manoj had been arrested by the Jeypore police in a dacoity case.
Security forces are engaging militants in gunfights at two separate locations in south Kashmir since Tuesday morning, said a police official.According to police, hiding militants fired when, on specific information, the police and Army cordoned off Nowbug Kund, Qazigund, and Kulgam.“The operation is on,” said the police. In a separate operation in Pulwama, security forces encircled Lam and Tral areas “after a tip off.”As searches were intensified towards the suspected spot, the hiding militants fired upon security forces, triggering an encounter, said a police official.
Students were practising football on the well-manicured lawns outside the Business and Management Studies Department at Kashmir University on Thursday, with food carts and canteens abuzz after five days of disruption following the death of an assistant professor in an encounter. However, even as apparent normalcy returned, anger and disillusionment were palpable among the students on the 247-acre campus.A stone’s throw from the Gandhi Bhavan auditorium, a 5X8 feet flex banner of slain assistant professor-turned-militant Muhammad Rafi Bhat atop the three-storey building that houses the Sociology Department greets visitors. Bhat was a faculty member of the department. More posters and banners lauding Bhat are emerging at other places on the campus with the slogan, “In memory of those who died for our freedom”.Atypical profileBhat was killed along with two Hizbul Mujahideen militants in Shopian on Sunday, just 36 hours after he joined the outfit. Bhat has left behind a new profile of a militant — in his thirties, he had been married for six years, and was on the cusp of a professional career of his choice, unlike the typical militant recruit most often in his early twenties.Sociology professor Anisa Shafi is perplexed and described Bhat’s move as “a mystery” that she could not crack “because he never discussed politics or expressed any anger”.Army chief’s remarksOn the edgy campus, where students unions are barred, scores of students outside the Law Department are busy debating General Bipin Rawat’s remarks on freedom and militancy. “Youth in Kashmir are not picking up arms to defeat the Army militarily. The gun is a challenge to the moral values of Indian democracy, to deliver justice in a very just cause,” a student said.Living in isolation“Students are living in isolation or cocoons. Social and interactive spaces have been destroyed on campus. Students could be driven to anything. Departments of KU should have debating societies in every department. One ideology should be allowed to clash with another through social spaces,” suggested Political Science professor Gul Wani.This week, a Kashmir University Teachers Association (KUTA) also suggested to Governor N.N. Vohra, chancellor of the varsity, to consider “constitution of a student’s council and grievance cell”.
Assam Chief Minister Sarbananda Sonowal has assured the parents of the two men lynched in Karbi Anglong that he would request the Chief Justice of the Gauhati High Court to fast-track the trial, an official statement released here on Wednesday said.Nilotpal Das (29) and Abhijeet Nath (30) were pulled out of their vehicle at Panjuri in Karbi Anglong district on June 8 and beaten to death by a group of irate villagers, who suspected them to be child-lifters.The victims’ fathers, Ajit Kumar Nath and Gopal Chandra Das, called on Mr. Sonowal on Tuesday evening and submitted a petition demanding maximum punishment for the culprits. They also demanded constitution of SIT for expeditious investigation in the case, the release said.Mr. Sonowal told them that the SIT had already been constituted under a Deputy Superintendent of Police and acting swiftly, the Assam police had nabbed all the accused within a short period of time, it said.A total of 64 people, including the prime accused, have been arrested in the case. The CM is personally monitoring the progress of the case.
A 10-member diving team from the Eastern Naval Command in Visakhapatnam reached eastern Assam’s Sivasagar town to help in the ongoing operation to locatea family of five that went missing after their vehicle plunged into the Dikhow river on September 1.Assam Chief Minister Sarbananda Sonowal, supervising the rescue operation, had sought naval help via the Prime Minister’s Office and the Ministry of Home Affairs, although a rescue team comprising the Army and disaster response forces have been searching for the vehicle and its occupants.The naval team arrived with diving equipment, inflatable boats and side scan sonar aboard an IAF aircraft that landed at the Jorhat air base from where it proceeded to Sivasagar by road. The team would be conducting search operation on Tuesday morning.‘Car was speeding’Eyewitnesses said the car, moving at high speed, fell into the river after the driver lost control. The five occupants of the car were identified as Haren Bora, his mother Phunu Bora, wife Punou Bora, and daughters Simpi and Munmi Bora. “A 44-member team of National Disaster Response Force team, a 30-member State Disaster Response Force team from three districts, a 14-member Para (Special Force) and five members from the Civil Defence have been at work using 10 boats,” a Sivasagar district official said.
Play the video above, and it won’t take you long to notice there’s something off about it. Rather than drifting down toward the forest below, the snow is falling …up? Then it hits you: The video is running backward. Now, a computer watching the movie could arrive at that same realization. For the first time, scientists have taught computers to figure out the direction of time in videos, a result that could help researchers better understand our own perception of time.Computer vision—a field focused on how computers could learn to detect objects, motion, or even human emotions and intentions in photographs and video—has long fascinated computer scientists, with applications ranging from more realistic-looking video games to video surveillance and intelligence. At the same time, computer vision has attracted the interest of psychologists, who hope to use it to study how people turn raw visual data into an understanding of the world around them.The latter question led Lyndsey Pickup, now a human and computer vision researcher at Mirada Medical in Oxford, U.K., to wonder how we tell the difference between time running forward and backward in movies. After all, we only ever observe time running forward in the real world—a concept called time’s arrow. How do we pick up on it when a movie has put time arrow’s in reverse? And might she be able to teach computers to make the same observation?Sign up for our daily newsletterGet more great content like this delivered right to you!Country *AfghanistanAland IslandsAlbaniaAlgeriaAndorraAngolaAnguillaAntarcticaAntigua and BarbudaArgentinaArmeniaArubaAustraliaAustriaAzerbaijanBahamasBahrainBangladeshBarbadosBelarusBelgiumBelizeBeninBermudaBhutanBolivia, Plurinational State ofBonaire, Sint Eustatius and SabaBosnia and HerzegovinaBotswanaBouvet IslandBrazilBritish Indian Ocean TerritoryBrunei DarussalamBulgariaBurkina FasoBurundiCambodiaCameroonCanadaCape VerdeCayman IslandsCentral African RepublicChadChileChinaChristmas IslandCocos (Keeling) IslandsColombiaComorosCongoCongo, The Democratic Republic of theCook IslandsCosta RicaCote D’IvoireCroatiaCubaCuraçaoCyprusCzech RepublicDenmarkDjiboutiDominicaDominican RepublicEcuadorEgyptEl SalvadorEquatorial GuineaEritreaEstoniaEthiopiaFalkland Islands (Malvinas)Faroe IslandsFijiFinlandFranceFrench GuianaFrench PolynesiaFrench Southern TerritoriesGabonGambiaGeorgiaGermanyGhanaGibraltarGreeceGreenlandGrenadaGuadeloupeGuatemalaGuernseyGuineaGuinea-BissauGuyanaHaitiHeard Island and Mcdonald IslandsHoly See (Vatican City State)HondurasHong KongHungaryIcelandIndiaIndonesiaIran, Islamic Republic ofIraqIrelandIsle of ManIsraelItalyJamaicaJapanJerseyJordanKazakhstanKenyaKiribatiKorea, Democratic People’s Republic ofKorea, Republic ofKuwaitKyrgyzstanLao People’s Democratic RepublicLatviaLebanonLesothoLiberiaLibyan Arab JamahiriyaLiechtensteinLithuaniaLuxembourgMacaoMacedonia, The Former Yugoslav Republic ofMadagascarMalawiMalaysiaMaldivesMaliMaltaMartiniqueMauritaniaMauritiusMayotteMexicoMoldova, Republic ofMonacoMongoliaMontenegroMontserratMoroccoMozambiqueMyanmarNamibiaNauruNepalNetherlandsNew CaledoniaNew ZealandNicaraguaNigerNigeriaNiueNorfolk IslandNorwayOmanPakistanPalestinianPanamaPapua New GuineaParaguayPeruPhilippinesPitcairnPolandPortugalQatarReunionRomaniaRussian FederationRWANDASaint Barthélemy Saint Helena, Ascension and Tristan da CunhaSaint Kitts and NevisSaint LuciaSaint Martin (French part)Saint Pierre and MiquelonSaint Vincent and the GrenadinesSamoaSan MarinoSao Tome and PrincipeSaudi ArabiaSenegalSerbiaSeychellesSierra LeoneSingaporeSint Maarten (Dutch part)SlovakiaSloveniaSolomon IslandsSomaliaSouth AfricaSouth Georgia and the South Sandwich IslandsSouth SudanSpainSri LankaSudanSurinameSvalbard and Jan MayenSwazilandSwedenSwitzerlandSyrian Arab RepublicTaiwanTajikistanTanzania, United Republic ofThailandTimor-LesteTogoTokelauTongaTrinidad and TobagoTunisiaTurkeyTurkmenistanTurks and Caicos IslandsTuvaluUgandaUkraineUnited Arab EmiratesUnited KingdomUnited StatesUruguayUzbekistanVanuatuVenezuela, Bolivarian Republic ofVietnamVirgin Islands, BritishWallis and FutunaWestern SaharaYemenZambiaZimbabweI also wish to receive emails from AAAS/Science and Science advertisers, including information on products, services and special offers which may include but are not limited to news, careers information & upcoming events.Required fields are included by an asterisk(*)To find out, she and her collaborators broke down 180 YouTube videos into square patches of a few hundred pixels, which they further divided into four-by-four grids. Combining standard techniques for discovering objects in still photographs with motion detection algorithms, the researchers identified 4000 typical patterns of motion, or “flow words,” across a grid’s 16 cells. The gentle downward drifting of snowflakes, for example, would be one flow word. From those patterns, the team created flow word descriptions of each video along with three other versions—a time-reversed version, a mirror-image version, and a mirror-image and time-reversed version. Then, they made a computer program watch 120 of these clips, training it to identify which flow words best revealed whether a video ran forward or backward.When they tested their program on the remaining 60 videos, the trained computers could correctly determine whether a video ran forward or backward 80% of the time, the team reported this week at the IEEE Computer Society Conference on Computer Vision and Pattern Recognition in Columbus, Ohio. A closer analysis found that flow words associated with divergence (water splashing outward as someone dives into a pool) or dissipation (a steam train’s exhaust spreading out in air) were especially good indicators of the direction in which time was moving.In principle, the work could provide clues about how humans, as well as computers, perceive time passing, Pickup says, and reverse-time videos could play a role akin to the optical illusions and reverse-color photographs psychologists have used to study visual perception in the past. Seeing time running backward is “really captivating,” and continuing the research might help her team figure out why, she says.Shai Avidan, an associate professor of engineering at Tel Aviv University in Israel who wasn’t involved with the work, says that the team is the first to ask, “Can we analyze and understand” what attributes distinguish backward from forward video? It’s an intriguing if largely academic question. Still, practical applications may be possible. Avidan compares the flow words approach to earlier work on identifying different kinds of texture in still images. Though studying image textures was considered “superficial” 15 years ago, he says, the tools developed to do so have since proved essential for engineers working on how to reduce noise in low-light digital photographs and other images. By identifying the subtle features that indicate time’s arrow and separating those from noise, flow words could play a similar role for improving otherwise fuzzy low-light video, Avidan ventures.Regardless of any possible applications, “we just thought it was a great problem,” says Pickup’s co-author and computer scientist William Freeman of the Massachusetts Institute of Technology in Cambridge. Pickup agrees: Teaching computers to see the arrow of time combines computer science, physics, and human perception to get at the heart of the question, “How do we understand the visual world?”
Blue whales (Balaenoptera musculus), the largest animals on Earth, have been slow to recover since they were nearly hunted to extinction in the last century. But now, scientists say that the population of California blue whales, which numbers about 2200, is almost as high as it was in the early 1900s—a recovery that should be celebrated as a conservation success story. The scientists reached this conclusion after modeling the number of California blue whales, which range from the equator to the Gulf of Alaska, that were killed between 1905 and 1971. The overall take was a surprisingly low 3400, the scientists report today in Marine Mammal Science. In contrast, some 346,000 were harpooned in Antarctic waters. The difference in the population sizes reflects the difference between the two environments; the Antarctic is able to sustain a far larger number of whales. Now that the California blue whales are almost fully recovered, their population is growing more slowly.
