ScribeMedia.org produced a number of video interviews at StreamingMedia West, including an interview with StreamingLearning Center's founding visionary, Jan Ozer (sorry, couldn't resist, writing in the third party is so freeing). As the title suggests, host Peter Cervieri and I discuss WebM, HTML5 and several other issues. Click over to the main article to see the video.

I just finished my H.264 vs. WebM Bakeoff presentation - you can download the PDF below.

You’ve heard the hype about VP8, but how does it really compare to H.264? This session compares quality, encoding speed, and playback requirements. It also details access to VP8 encoding from within live and on-demand encoding tools, the availability of hardware playback acceleration, and features like adaptive streaming. The session also reviews VP8 usage by YouTube and other websites.

This article compares H.264 to WebM, Google's implementation of the VP8 codec, using three variables (encoding time, compressed quality, and CPU requirements) for playback on three personal computers. Here's the CliffsNotes version of the results: Using Sorenson Squeeze to produce both H.264 and WebM, the latter definitely took longer, but there are techniques that you can use to reduce the spread to less than 25%, which is pretty much irrelevant. Though H.264 offers slightly higher quality than the VP8 codec used by WebM using the aggressive (e.g., very low data rate) parameters that I tested, at normal web parameters, you couldn't tell the difference without a score card. Even compared to H.264 files produced with x264, VP8 holds its own.

WebM/VP8 is Google's recent entry into the codec market. Here's a roughly chronological list of resources about the codec/technology.

As part of my First Looks review of VP8 and WebM for StreamingMedia.com, ran a bunch of VP8 and H.264 comparisons, initially using the MainConcept H.264 codec, since that's the codec included with Sorenson Squeeze, which I used to produce the VP8 files. Then, I added some comparison files produced using the x264 codec, encoding via the QuickTime-based x264Encoder version 1.2.13 (dated 6/27/2010). 

You can read the StreamingMedia article here. In this article, I present the frame comparisons that were too big to fit in the StreamingMedia article, plus present URLs for the streaming files that I created and compared. 

VP8 is now free, but if the quality is substandard, who cares? Well, it turns out that the quality isn't substandard, so that's not an issue, but neither is it twice the quality of H.264 at half the bandwidth.
