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.
