    No the container for both is the same and it is ogg. So lets say you transcode movie1.mpeg with theora. The result will be movie1.ogg.
    If you transcode the audio sound1.wav with vorbis the result will be sound1.ogg as well.
    But just to be more obvious if an ogg file contains video or just audio, usually people just rename the movie1.ogg to movie1.ogv (ogg video) and sound1.ogg to sound1.oga (ogg audio) or they leave that last one as just sound1.ogg.
    So finally for movies we have the ogv extension and for audio ogg or oga


    Now about Theora Thusnelda:
    HURAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAH

      I've been waiting for Theora to reach a decent quality level. I want to use it for backup up my personal DVDs, but it just wasn't quite there before. Looking good. This is certainly adequate for youtube stuff.

        I have found screenshots comparing 1.0 vs. 1.1 on polish news page:

        Looks promising for me. Would like to see Google reconsidering using Theora for Youtube. Last time they complained about lower quality for low resolutions movies.

          If we judge just from the pics, it looks promising yes.

          That would be a really big hit to flash and h264.

            Errr... Only h.264, really. Flash is a container. You can junk whatever you want inside it, I think.

                Don't know about matched, but it's certainly getting closer:

                and it has already surpassed 263:

                  What is more important is what Google will do with on2, once the purchase is finalized.

                  http://www.on2.com/blog/2009/08/goog...ty-on-the-web/


                  Very likely Google will make the VP codec open source, so VP can be the video codec for HTML5.


                  VP7 is used in Flash.

                    No. Google wanted h.264 for HTML5 fot it's awesome quality/size and hardware acceleration availability.

                      Yes Flash Video is a container. I just mean that with Theora implementation in youtube, you don't need flash player to play the videos in firefox since they are supported out of the box.
