How To Create a Blinking Eye Transition in After Effects

first_imgSome projects leave more room for creativity than others. If you’re looking for some out-of-the-box elements, check out this blinking eye transition.Some media, like music videos, aren’t constrained by the usual narrative filmmaking conventions, which allows filmmakers to create something unique that would be out of place in a narrative production. If you’re working in an experimental or free-form medium, here’s a little something to make your project unique: a blinking eye transition.The effect is simple enough. It primarily involves masking out the eye area, subtracting the mask, and then placing the footage behind the eye layer. Basic After Effects. However, upon further inspection, there are a few elements of the transition that may be a small challenge. What happens to the eyelashes mid-blink, as they would be a nightmare to mask around? How exactly do you time the blink? Let’s have a look.The MethodFirst, bring the footage of the blinking eye into After Effects and create a new composition.With the footage on the timeline, find the blink that works best for your transition, and trim the footage to start just before the blink, and then end when the eye is fully closed. We only want to use one blink in the composition. By using just the one blink, we can control the transition, so we can cut in the specific place (more on that later). Moreover, masking more than one blink would be a tremendous amount of work.With the perfect blink selected, find the spot in the timeline when the eye is fully open, and create a mask. Then change the type to subtract.We now need to animate the mask path, which we can do by clicking the keyframe stopwatch for the mask path.This is where I initially expected to stumble. How was I supposed to mask around the eyelashes as the eyelid closes? Well, you don’t. While we, as editors, will be watching the eyelashes enter the path of the mask frame by frame, the audience won’t see it because the transition will be over in a blink of an eye — quite literally. Since I captured my footage at 24fps, the eyelashes are caught up in motion blur, so they’re not very visible anyway.So, when you adjust the mask path as the eye closes, don’t worry about masking over eyelashes. Your primary goal is to make sure all of the sclera (white area) and the iris gets masked. To slightly remove the harshness of the mask, we’re going to introduce a soft feather of just 2px.For the eagle-eyed readers, you may have noticed in the second picture that the mask expansion stopwatch was also active. This was to remove the mask when the eyelid closes completely.It’s also a good idea to keep the eye quite dark and out of focus. This will help keep the focus of the composition on the scenes behind the eyelid, rather than the eye itself. To fix this, we’re going to do three things: decrease exposure, add a vignette, and add a gaussian blur. Since they are creative factors, the exact settings will depend on the darkness of your eye footage. I’m also going to increase the scale, so the eye itself takes up less of the composition.Now, the actual transitioning from scene to scene.The reason why we are only going to use one blink is that we need to be able to control when we want to cut to a different scene. If we allow the eye layer to freeze-frame before blinking again, we can allow our scene to unfold for a few seconds, and then play the blink footage again, but in reverse. This creates a transition that’s entirely under your control, rather than working according to the restrictions of the pre-recorded eye.This is how it looks on my timeline.Finished result: As I said in the introduction, you will mostly find this kind of transition in experimental or free-form work. Perhaps in a dream sequence or in a scene wherein somebody gets hypnotized. When you have the chance to work outside of the box, take advantage of it. Show your audience something they’re not used to.last_img read more

Albertas status of women minister joins Twitter debate over womens marches

first_imgEDMONTON – A minister in Alberta’s NDP government has chastised a tweet by the Opposition’s communications chair that slammed women’s marches held over the weekend.Status of Women Minister Stephanie McLean was responding to a Twitter post on Saturday from Sonia Kont of the United Conservative Party, who stated that “ideological marches like the one in Washington” do not empower women.Kont added that the last time she checked everyone had the same rights in society, and the march lacked clarity and purpose.McLean responded that the UCP “ridiculed the strength of women marching together in solidarity and using their voices fighting for equality.”Dozens of marches were held in communities across Canada on Saturday, a year after women’s marches that sprang up around the globe in the wake of Donald Trump’s inauguration as U.S. president.The event drew a large crowd at the provincial legislature in Edmonton, and an even larger one in Calgary.“What rights have women lost in the United States or Canada? It’s a shame these marches don’t say a word about the horrific conditions women face in the Middle East,” Kont tweeted in response to criticism of her initial posts.“Did this march also voice support for Iranian women or the Kurdish female heroes fighting ISIS? How about the Saudi Arabian women? They deserve rights and freedom too.”McLean, meanwhile, noted that women face a pay gap with men, are responsible for more childcare, make up only a fraction of corporate boards, and face other issues such as domestic violence.A number of people supported McLean on Twitter, including one who linked to a tweet by former prime minister Kim Campbell.“What I love about these marches are that they are everywhere,” Canada’s first and only female prime minister said. “And there are LOTS of great MEN smiling and marching with the women!”But there was also support for Kont, including a tweet from fellow UCP member Bettina Pierre-Gilles, who is listed on the party’s website as a member of its policy committee.“I couldn’t agree more with you Sonia. I’m a proud advocate for women and working our way to the top,” her tweet states.“These marches indeed only sends a message that only the loudest few can be heard, while nothing is advocated on policies.”UCP Leader Jason Kenney added his own voice to the discussion on Sunday evening.“Proud that the United Conservatives have so many strong, outspoken women as members. Our party doesn’t force conformity. Members are free to hold differing views,” Kenney tweeted.Canadian organizers said Saturday that 38 communities were hosting marches, rallies and other events.Police in Calgary tweeted their own support for the event in that city, along with a picture of a uniformed officer with marchers.“We were honoured to not only ensure the (march) was safe for all participants, but also to show our support by taking part,” the tweet from the Calgary Police stated.last_img read more

Applications for US unemployment benefits fall to 264000 lowest in 8 weeks

WASHINGTON – The number of Americans seeking unemployment benefits fell last week to the lowest level in two months, suggesting employers remain confident enough in the economy to hold onto their workers.The Labor Department said Thursday that weekly applications for unemployment aid dropped 11,000 to a seasonally adjusted 264,000. That’s the lowest level since July, when applications plunged to a 41-year low.Applications are a proxy for layoffs, so the decline indicates that employers are cutting fewer jobs. Americans are enjoying strong job security: Applications have been below 300,000 for the past six months, which hasn’t happened since 1973.Employers have also been hiring at a solid pace, adding an average of 243,000 a month in the past 12 months. That has brought the unemployment rate down to 5.1 per cent, a seven-year low.The health of the job market will play a crucial role in the Federal Reserve’s deliberations Thursday as it wraps up a two-day meeting. Fed policymakers may decide to raise the short-term interest rate they control for the first time in nine years.Some economists argue the job market has largely recovered from the Great Recession and can now withstand higher interest rates. But even so, many expect that other considerations, such as inflation that is stubbornly below the Fed’s target of a 2 per cent annual rate, may cause the Fed to hold off.Not all economists agree that hiring has fully recovered from the downturn. The number of people working part time but who would prefer full-time work is far higher than it was when the recession began in December 2007. And the percentage of Americans working or looking for work has fallen sharply since then.The number of people receiving benefits fell 26,000 to 2.24 million, the government said. That figure has declined 8.8 per cent in the past year. Many former recipients have gotten jobs, but some have used up all the benefits available to them.

SMMT Budget response

*An SMMT survey, commissioned in November 2004 among senior industry executives, showed that 95 per cent felt that the burden of legislation would add significant costs to their business in the next five years. Automotive Manufacturing – the Industry Perspective is available to download from http://lib.smmt.co.uk/articles/news/News/issues%20survey.pdfClick to share on Facebook (Opens in new window)Click to share on Twitter (Opens in new window) The industry had urged stability in taxation and greater clarity on incentives to promote cleaner fuel and vehicle technologies in its Budget submission. Today’s statement presented a mixed bag. SMMT today welcomed plans to introduce guidelines for the implementation of new EU regulations. The announcement by Chancellor Gordon Brown in his Budget, will reassure an industry which has consistently raised concerns about increases in the regulatory burden and the effect that ‘gold plating’ has on UK competitiveness.* Cleaner vehicle incentives SMMT is disappointed that the Chancellor failed to address concerns about cleaner vehicle incentives. Following the collapse of the Powershift scheme, manufacturers now need clear direction so they can plan for the introduction of the most environmentally friendly new vehicles. Government must address this urgently through dialogue with the industry on a new scheme based on stability and a technology-neutral approach. R&D Plans to enhance R&D tax credits have been welcomed by SMMT. The move should ensure that more companies in the automotive sector are encouraged to allocate greater resource to this key area. Chancellor follows industry lead on new car labelling The UK motor industry has taken a lead in producing better consumer information for new car buyers through its colour-coded label. Changing the way VED bands are categorised will now mirror the label’s A-F format, making the relationship between lower CO2 emissions and lower taxation clearer. SMMT is encouraged by the Chancellor’s decision to defer fuel duty rate rises until September 2005. However, with a volatile global oil market, the industry remains cautious about the cost burden that future ad hoc above inflation increases will bring for consumers after the election. Taxation SMMT has welcomed the freeze on corporation tax and the climate change levy. News that the minimum threshold for company car tax will be held at 140g/km of CO2 until 2007/08, has also been welcomed. It is a decision that brings long-term clarity to the new car fleet market. SMMT chief executive, Christopher Macgowan, commented, ‘This is news that will be widely welcomed by all motor manufacturers. Today’s commitment to a light regulatory touch follows improved dialogue between industry and the government and should prevent unnecessary burdens on a sector facing rising supply chain costs and exchange rate pressures.’ read more

Reeva Steenkamp case Steroids found at Oscar Pistorius home reports

first_imgBANNED STEROIDS WERE reportedly found at the home where Oscar Pistorius is accused of murdering girlfriend Reeva Steenkamp.South African police are investigating whether Pistorius may have shot Steenkamp in an apparent episode of ‘roid rage’ – an aggressive outburst caused by the performance-enhancing drugs.“Steroid drugs were found at Pistorius’ home together with evidence of heavy drinking,” a source told The Sun. “That’s why police have specifically ordered that he be tested for steroids.”Police refused to respond to the claim today, though sources close to the investigation had previously told a local newspaper that the star Paralympian and Olympian’s blood was being tested for drugs. Steenkamp, 29, was shot dead on Thursday at Pistorius’ home in a secure housing estate near Pretoria.Police also reportedly found a bloodied cricket bat, though Pistorius’ family has strongly denied he intentionally killed Steenkamp. Pistorius, who remains in custody at a Pretoria police station, is due to appear at a bail hearing in court tomorrow.The hearing will be the first opportunity for the prosecution to detail the reasons why the 26-year-old double-amputee runner was charged with murder. Prosecutors allege the killing was premeditated.Further reports today claimed Reeva Steenkamp was shot in the hip in Pistorius’ bedroom before coming under further attack as she sought shelter in the bathroom.Meanwhile, Pistorius’ agent said his sponsors were committed, despite announcing that all upcoming races, including appearances in Sydney, Melbourne and Perth, had been cancelled.“All sponsors have given us their commitment towards Oscar, based on the relationships that they have formed with him over the past years,” Peet van Zyl said. “They are quite happy to allow the legal process to take its course before they make any other further and formal announcements on it.”RTÉ to block coverage of rugby internationals in NI from next year6 Nations update: Henry out for a month, O’Donnell and Madigan called uplast_img read more

Nvidia believes Tegra 5 will outperform a PS3

first_imgMobile gaming has come on leaps and bounds over the last few years due in large part to the rate at which the hardware is improving. Each new generation brings with it a performance bump, which has seen the smartphones in our pockets and tablets in our bags manage near console-quality gaming.But how close to the current generation of consoles are mobile devices? According to Nvidia, the next generation of mobile processors will in fact outperform both a PlayStation 3 and Xbox 360.That claim has been made by Tony Tamsai, Nvidia’s senior vice president of content and technology. And going on the performance bump each generation of Nvidia’s Tegra chips has brought so far, he may have a point.The PS3 is rated at 200GFLOPS, where as the PS4 takes a massive leap forward to 1800GFLOPS. Now if you look at Nvidia’s mobile processors, the Tegra 3 ran at 12 GFLOPS, Tegra 4 is set to bring near 7x increase and will run at 80GFLOPS. So it’s actually quite a confident prediction to make that when Tegra 5 arrives it will easily achieve more than 200GFLOPS of performance.Looking at Nvidia’s release history, Tegra 2 launched in Q1 2010, Tegra 3 launched in Q1 2012, and Tegra 4 is set to launch in the next few months. So it’s safe to assume that Nvidia will be rolling out Tegra 5 at some point in mid-2015. If we see the same level of performance gain between Tegra 4 and 5 as seen between Tegra 3 and 4, then Nvidia should be getting close to PS4 performance levels by the time Tegra 6 is rolled out.But what Tegra won’t do for the foreseeable future is get anywhere near Nvidia’s top-of-the-line desktop graphics card the GeForce GTX Titan. With a rating of 4500GFLOPS, it’s by far the most powerful card on the market by a massive margin.last_img read more

Gaz à effet de serre les forêts captent de moins en moins

first_imgGaz à effet de serre : les forêts captent de moins en moins de carboneVéritable poumons de la planète, les forêts stockent de moins en moins de carbone depuis une dizaine d’années. Un phénomène surprenant, quand dans les années 1990, le réchauffement climatique semblait favoriser la croissance des végétaux, et donc celle de leur absorption du dioxyde de carbone (CO2).Publiée dans la revue Science, une récente étude menée par des chercheurs de l’université du Montana, révèle que le stockage naturel de CO2 par la végétation tend à diminuer depuis les années 2000. Une conclusion tirée des analyses de données satellitaires de la NASA. Les travaux ont permis de constater que la végétation mondiale avait absorbé au cours des dix dernières années, 550 tonnes de carbone de moins que lors de la précédente période étudiée.   À lire aussiQui est Greta Thunberg, proposée pour un prix Nobel à seulement 16 ans ?En 2003 pourtant, de telles recherches avaient permis de constater qu’entre 1982 et 1999, le réchauffement climatique avait engendré une augmentation du stockage du dioxyde de carbone atmosphérique par les plantes. Leur croissance favorisée par les conditions climatiques, les végétaux absorbaient en captant d’importantes quantités de CO2.Mais de graves sécheresses ont touché l’Australie, l’Amérique du Sud et l’Afrique, où 70% des arbres ont capté moins de CO2 qu’habituellement au cours des dix dernières années. Une diminution que ne compense pas la tendance inverse observée dans l’hémisphère nord.Les auteurs de cette étude restent prudents quant aux conclusions qui peuvent être tirées de leurs travaux. S’ils estiment que “le changement climatique augmente la fréquence des grandes sécheresses régionales et cette tendance devrait se poursuivre dans un avenir proche”, ils soulignent que “le suivi des évolutions climatiques mondiales sera essentiel pour déterminer si la réduction observée du pouvoir de stockage des arbres constitue une simple variation décennale ou un véritable tournant de la séquestration terrestre du carbone.”Le 24 août 2010 à 20:02 • Emmanuel Perrinlast_img read more

MacBook des batteries vulnérables

first_imgMacBook : des batteries vulnérables ?Le chercheur en sécurité américain Charlie Miller a mis au jour une nouvelle faille dans un système d’Apple. Ce sont cette fois les MacBook, et plus précisément leurs batteries, qui sont concernés. D’après celui-ci, le micro-contrôleur utilisé dans lesbatteries Lithium des ordinateurs portables d’Apple peut être compromis.Connu pour avoir mis au jour plusieurs failles dans les systèmes d’Apple, et notamment les iPhone 2G et 3GS, le chercheur en sécurité Charlie Miller assure avoir réussi à compromettre les ordinateurs portables MacBook, MacBook Pro, et MacBook Air. Sur le site blackhat.com, il explique que le micro-contrôleur des batteries des Mac portables peut devenir le vecteur de code malveillant.Ce micro-contrôleur est chargé de superviser les batteries, en lien avec l’ordinateur, l’interface graphique et l’usager. Il permet de réguler la consommation d’énergie de la machine, et indique le niveau de charge via une icône affichée sur l’écran de l’ordinateur. Or, cette communication permanente avec l’ordinateur constitue une menace de sécurité, comme Charlie Miller assure l’avoir démontré. Le hacker affirme avoir réussi à désactiver sept batteries de portables Mac, en obtenant les mots de passe protégeant le micro-contrôleur. Des problèmes de sécurité tels que “surcharge ou incendie” C’est grâce à l’analyse d’une mise à jour de 2009 obtenue avec la méthode de la rétro-ingénierie (reverse engineering) qu’il aurait découvert les mots de passe et ainsi réussi à reprogrammer des batteries. Une reprogrammation qui “peut suffire pour causer des problèmes de sécurité, tels que la surcharge ou un incendie” souligne Charlie Miller.Toutefois, d’après le site Clubic, le hacker pourrait présenter lors de la prochaine BlackHat Conference, un forum dédié aux professionnels de la sécurité IT, un outil permettant de modifier les mots de passe des batteries, et donc de prévenir d’éventuelles attaques.Le 27 juillet 2011 à 10:52 • Maxime Lambertlast_img read more

HandsOn Sparklite Is a Fun ZeldaInspired Roguelike

HandsOn Sparklite Is a Fun ZeldaInspired Roguelike

first_img If you’ve read my work here on Geek.com or seen some of my tweets then you’ll know I’m not exactly a fan of roguelikes. I made this abundantly clear in my review of Rad. As I said in that write-up, though I don’t care for the genre, I’m always willing to try out new games to see if one clicks with me. I’m here to tell you that I have found this mythical roguelike with Sparklite. This title is the very definition of a surprise and one which I hope sets a new precedent for roguelikes.Though a roguelike at its core, Sparklite takes strong inspiration from The Legend of Zelda series. Specifically, games like A Link to the Past, The Minish Cap, and Link’s Awakening. Its top-down camera angle, screen transitions, map design, and pixel art hearken back to those classic Zelda titles. Of course, the big difference here is that Sparklite features randomly-generated maps and its own take on permadeath. These disperate elements serve to create a unique and satisfying experience.Sparklite stars a protagonist named Ada, who uses tools and gadgets to explore her strange world. Persistent earthquakes cause the land’s geography to constantly shift. This plot element is a genius way to explain the randomly-generated maps. Though the land changes, the one constant in this world is the sparklite element. With this, citizens power their floating cities and machinery. However, dangerous monsters, both great and small, stalk the land in search of the very sparklite Ada seeks.Core combat consists of melee attacks. In the demo I played, Ada used an upgradeable wrench to dispatch foes with a series of quick slashes. What spices up combat is the ability to dash. Some of the foes I faced, particularly the bosses, forced me to keep a steady finger over the dash button in case I had to make a quick escape. Considering how you’re thrown back into the main hub when you lose health, you’ll want to use dash to avoid any and all attacks if possible.Permadeath is a key feature of roguelikes. While Sparklite has a form of permadeath, it isn’t as punishing as it is in other titles. When enemies render Ada unconscious, she returns to the game’s hub world. You lose all progress with regard to missions. For example, if you found a quest item, you will lose it upon death and need to retrieve it again. What makes permadeath tolerable is that Ada remains as your main character and she gets to keep any and all collected sparklite. This is important since it prevents players from feeling frustrated over losing their progress upon death.The other key element that makes Sparklite digestible is the ability to upgrade. During my demo, I farmed to get 100 sparklite in order to upgrade my wrench’s attack. I died several times in the attempt but I rested assured knowing I’d always leave with some sparklite on every run. My persistence paid off when I eventually had enough sparklite to procure the desired upgrade. This encouraged me to brave the wilds instead of giving up in frustration.The randomly-generated maps I explored contained the same basic elements in different configurations. What I found interesting is how some maps seemed nearly identical to each other while others were wildly different. Since the land always changes, it is easy to lose one’s way. Thankfully, the in-game map always displays your objectives. This is a great feature that prevents players from wasting time wandering around looking for things to do.During my travels, I ran into a number of NPCs that gave me side quests. These quests are also randomly generated. For example, during one run, I found a boy seeking his lost sister. He tasked me with giving her half of a medallion. I died during the middle of the quest, thereby canceling it. On another run, I found the sister who gave me her half of the medallion. During this instance, I managed to find her brother and complete the quest. This approach to quests (like most of Sparklite) keeps subsequent runs feeling fresh.Along with weapons and health, you can upgrade your home base and turn it into a functioning society. After completing quests for NPCs, they’ll join your base and set up a workshop where you can purchase upgrades and equipment. This incentivizes players to scour each of the different maps looking for these useful characters. I didn’t get a full taste of this base building-ish aspect, but I can see myself becoming obsessed with finding every NPC I can. After all, every upgrade helps you survive the harsh world and shops are the only way to make that happen.The big highlight for me was the one boss battle I experienced. Taking place within a dark dungeon, I battled a giant mechanical foe whose main weapon was a ball and chain. Dodging the oncoming ball proved challenging but I managed to do so by studying the boss’ movements. The biggest challenge came when the ball began to suck in air. The trick to avoiding the powerful vacuum was to run instead of pressing dash. I didn’t get to defeat the boss, though I came close. The battle proved exhilarating and I can’t wait to see how inventive the other boss battles get.Sparklite is pure eye candy. Its bright, vibrant graphics recall the glory days of the 16-bit eras. Animations are buttery smooth and it’s easy to read enemy movements. Despite the random nature of maps, each has a life of its own. I mostly played within a forest, but the game also has other environments to explore. Even in an industry overflowing with “pixel art” games, Sparklite stands out with its distinctive and inviting graphics.Sparklite is the one roguelike I actually, well, like. Though I did enjoy Skyhill, Sparklite is more up my alley because of its overt nods to the 16-bit eras. It proudly wears its Zelda inspiration on its sleeves. Combat feels tight and responsive, while the randomly-generated maps keep players on their toes. The fact that you’re always making some kind of progress is what helps raise Sparklite above other roguelikes. I had a blast playing the demo and eagerly await the finished product. Sparklite is a winner in my book.Sparklite will release later in 2019.
