Moving Pictures

They’ve been lurking in the background for years, but animated GIFs have had a comeback in popular culture lately. People use the format to create humorous Internet memes, low-resolution video clips of events like cool sports plays or their own mini-cartoons. Tumblrs are spilling over with animated GIFs, El Kaiser has created an excellent Pop Tech Jam GIF and BuzzFeed even had a list of favorites for 2012. (Like wildlife? Check out the Animal PerfectLoop site.)

Not bad for a file typet that’s been around since the Reagan administration. The GIF format was first introduced in 1987 by CompuServe. GIF itself stands for Graphics Interchange Format and some have argued how to pronounce the acronym. (The creators of the format have said they pronounce it like a certain peanut butter-brand chosen by choosy mothers, although some dictionaries support both pronunciations.)

Animated GIF files are generally smaller than the average video file and only support 256 colors. An animated GIF, which is a series of still pictures (frames) combined together to create action or motion, does not contain sound like most video formats do. Video files also typically have at least 24 frames per second or higher to create fluid motion in a wider range of colors. This small file size of the animated GIF and its compatibility led to their relative popularity in the early days of the Web when dial-up connections were too slow to handle streaming video (or much of anything else besides text).

Before you decide how you want to make your animated GIF file, you should select the images to use for the project, like a sequence of pictures of say, a hamster on its wheel or the best three seconds of a video clip. If you’re using still photos or illustrations, all the images used should be sized to the same dimensions. The fewer pictures used, the faster and choppier the animation will be in the final GIF file. Some basic animated GIF files just use four images. For more fluid, video-like motion, use more images in the sequence.

Recent versions of Adobe Photoshop Elements, a popular photo-editing program designed for home users, can make animated GIFs using the Layers feature. If you have one of these programs, you can use it to create animated GIFs:

You can also use snippets of video and convert the clip to an animated GIF. The How-To Geek site has instructions for converting bits of YouTube clips to animated GIFs here and the Switched blog has a tutorial on the same topic here.

Plenty of Web sites also offer simple GIF conversion. You upload a series of images (or a short video clip) and the site crunches your upload into a GIF for you. MakeaGIF and Gifninja are two sites that can handle the job.

Want to animate your GIFs on the go? Check out your app store for options. Gifboom is one such mobile app with iOS and Android versions available.

But really, the technical stuff isn’t so hard. The hard part of finding that perfect GIF-able moment, but when you do, you feel like this:

Episode 41: April Foolishness and Big Data

This week we go big on Pop Tech Jam! Technology expert and author Phil Simon talks to J.D. about his new book, Too Big to Ignore: The Business Case for Big Data and Pedro reviews two new headphones in his never-ending quest for the perfect subway headphones. In the news,  Amazon’s Cloud Drive service takes on Dropbox; Microsoft’s Windows Phone making inroads against Apple and Android’s dominance; Google’s new privacy czar; and mobile ads that talk back.

Episode 41 News: Game of Bacon

Tech companies do love the April Fool’s Day gags, don’t they? In general, some “jokes” work better than others, but everyone seems to be moving on and getting back to business as we ease into spring. Take Amazon — its Cloud Drive can now give your files that syncing feeling. The company just released a new desktop app for Windows and Mac gives that lets you copy files to your online drive by just moving them into a desktop folder, just as you can do with Microsoft SkyDrive, Dropbox and other services. (As Ars Technica and others have pointed out, the app requires Java, but not that worrisome browser plug-in.)

Microsoft is getting it out there: Windows Phone handsets seem to be getting some traction in the marketplace (right before BlackBerry has sold a million new Z10 phones already) and the Internet Explorer 10 almost doubled in market share, thanks to the Windows 7 version arriving in February as an automatic update. Windows 8 is still trying to find its place in the world, and has risen to claim 3 percent of the desktop operating system pie, according to Net Applications in its report for March.

Meanwhile, over at Google, Alma Whitten, the Director of Privacy, is leaving the job this summer. Lawrence You, an engineering director, will be taking over the privacy-and-security department in June. In other company privacy news, Google is facing new probes and possible fines for privacy violations in Europe. (And on the topic of international incidents, Apple CEO Tim Cook has written a letter of apology to the company’s Chinese customers. )

Talking back can get some results and Nuance, the speech-recognition company, is working on mobile ads that can talk back to customers. Hopefully, the ads will wait until they are spoken to before nattering on about the product.

tapestryOut in space, astronomers have discovered a new comet that could be one of the visibly brightest in decades. (But will it be as popular as Halley’s comet, which has turned up in song, story and tapestry for centuries? Eh, probably not.) Hopefully, the Mars rovers will get a few good shots of Comet Ison when it passes by the Red Planet — and US astronaut Buzz Aldrin hopes the United States will take a shot at sending astronauts to Mars. He lays out a plan in his new book, Mission to Mars: My Vision for Space Exploration, due out May 7th.

And finally, spring is here on the northern hemisphere, on the calendar if not in the weather forecast. Baseball is back, and so are a few very popular TV programs, including the BBC’s Doctor Who (which featured a geektastic episode about scary Wi-Fi) and HBO’s Game of Thrones (which broke the BitTorrent Swarm record with more than a million downloads in less than a day). HBO, however, does not seem to be worried.

Fans of these two franchises can also take in David Tennant (the beloved 10th Doctor) in the BBC miniseries Spies of Warsaw this month, and enjoy John Lanchester’s 4,600-word essay on George R.R. Martin’s opus in the London Review of Books. Both might be a nice distraction for all those who were crushed to find out, alas, that Scope Bacon was not real.

Sound Decisions

In his eternal quest for the Perfect Pair of Headphones that sound great and keep the background noise out of the mix, Pedro Rafael Rosado takes a listen to two new models:

P3

The Bowers & Wilkins P3 headphones ($199.99)

700M

The NuForce NE 700M titanium-coated in-ear headphones ($75)

How did the gear hold up against the cacophony of the New York City subway system?
El Kaiser tells all in Episode 41.
