an update on open video codecs and quality

Two days ago we posted a comparison by Greg Maxwell of low and medium resolution YouTube videos vs. Theora counterparts at the same bit rates. The result in that test was that Theora did much better at the low bit rate and more or less the same at the slightly higher bit rate. The conclusion being that Theora is perfectly appropriate for a site like YouTube.

Now Maik Merten has done the same with videos at HD resolution, comparing videos encoded by YouTube and a video encoded with the new Theora encoder at a managed bitrate. The results? Go have a look at the images in the post. Tell us if you can honestly see a major difference. We can’t.

    What is most important?
    Create a default Audio & Video codec for WEB that can be open directly on browser.
    But this codec MUST be open source, with quality and low CPU power use. THEORA is a candidate. Let’s test him!

      I completely agree!

    Well said,

    I’m so glad we have native support and the codecs improving all the time, hopefully one day we can get rid of adverts that use flash to redirect you anywhere they like and flash LSO cookies and have code that’s ratified by responsible browser developers that is as cross platform as can be and make life easier for developers by only needing to support one open format. ;)

    Great thanks for new VIDEO tag. I use ogg for web TV streaming. But how I did understand, new VIDEO element not yet support stream video – infinite file. This element can only single files play. It is thuth?

    No noticable difference. Theora is better because it’s free and open sourec.

    Very nice.

    I’ve followed up to original images and found no noticeable differences between them. Why I see face smoothing here (small format) but not there (large format)? What algorithm is used for resizing original images to thumbnails? I’ve downloaded original images and stretched them to 480×270 with Lanczos and Belinear algorithms. The images became almost identical.

    I know that H.264 is much better than Theora. You’ve used unknown codec with unknown settings for encoding, so I don’t believe that your results are correct. There is another comparison that looks more convincing: http://www.osnews.com/story/19019/Theora-vs-h.264/

    Wow, you’re so wrong. First, why are you comparing the resized images? This makes no sense. Second, that comparison you have (from which you “know” h264 looks better) is from late 2007. There was much done in the year and a half that occurred between then and when this comparison was done.
