Firefox 3.5 Beta Boosts Open Video Standard

Posted by kdawson on from the nothing-flashy dept.

bmullan writes "Dailymotion, one of the world's largest video sites, announced support for Open Video. They've put out a press release, a blog post on the new Open Video site, and an HTML 5 demo site where you can see some of the things that you can do with open video and Firefox 3.5. (You can get the Firefox 3.5 beta here.) Dailymotion is automatically transcoding all of the content that their users create, and expect to have around 300,000 videos in the open Ogg Theora and Vorbis formats."

    But Theora has come a long way since then, coming much closer to x264's fidelity.

    You must have missed the retraction that was done when it was shown that they were calculating PSNR wrong for x264. Theora is nowhere near the quality of even a low-range h.264 codec.

    'Publishing' the graph like that drew well-deserved scrutiny and unfortunately our own data was also off (although by considerably less). ffmpeg had another bug we didn't know about which caused it to mishandle the colorspace on x264 output, so the x264 PSNR value was too low by 1-4dB. Greg fixed the error in the data collection and immediately set about collecting new measures:

    If you actually read TFA, you might have noticed

    Do other browsers support this HTML tag? Yes, but our code works best on Firefox 3.5 beta and is not yet optimized for other browsers. We would be happy to work more closely with developers from Webkit and Opera.

    Considering that the demo is intended to show what an emerging standard can do better than current ones, it's understandable that they want it to look the best it can, which means they're going to want people to watch it using the optimized platform and not something that's barely going to run their demo.

    3 dB is a factor of ~ 1.41 times.

    A factor of two is 6 dB.

    Depends on what your working with. Just straight amplitude, 3dB = double. If you're working with power, then 6dB=double.

    But.. audio uses the amplitude scale.

    What does dB even mean in this context?
