robertogreco : codecs   5

""moDernisT" was created by salvaging the sounds and images lost to compression via the mp3 and mp4 codecs. the audio is comprised of lost mp3 compression material from the song "Tom's Diner", famously used as one of the main controls in the listening tests to develop the MP3 encoding algorithm.

Here we find the form of the song intact, but the details are just remnants of the original. the video was created by takahiro suzuki in response to the audio track and then run through a similar algorithm after being compressed to mp4. thus, both audio and video are the "ghosts" of their respective compression codecs. version one.

AnimGIFs need a better codec
"Short, looped silent video clips have become a medium. They're a way to quote, remix and comment on longer videos. They're a way to share jokes and cats' mishaps. AnimGIFs are to videos what Twitter is to blogs.

The problem is that the video codec powering this medium is horribly outdated and inefficient. Browsers already support better video codecs natively, but due to historical reasons, they're not allowing animGIFs to take advantage of the better technology.

The divide between "animations" and "proper videos" is a false dichotomy and creates needless complexity. Plenty of GIFs are conversions from YouTube and other videos. 4chan allows GIF-like WebM clips. Websites like gfycat and Twitter convert GIFs back to H.264 or WebM to save bandwidth.

RealPlayer is gone, codecs are not a pain any more

Annoying plug-ins from the '90s have left a long-lasting impression that video codecs must be slow, clunky and could not be played without a special ceremony. It's not true any more.

The latest codecs are not only much more bandwidth-efficient, they can be cheaper to decode as well (thanks to hardware acceleration and ability to seek). There is no reason to keep GIF as the only video codec with special privileges and force faster codecs to have limited usefulness."

Daring Fireball: Creating Ogg Theora Files on Mac OS X With ffmpeg2theora
"ffmpeg2theora is the one tool I found that simply just works for transcoding to Ogg Theora. The downside to ffmpeg2theora is that it’s only available as a command-line tool."
