Comments Posted On :The Moving Picture: Everything You Always Wanted to Know About H.264 but Were Afraid to Ask

It should also be noted that .h264 is a delivery format, NOT a codec to be used while working. For example, when working on the soundtrack of a video you need to be working with a video codec that has discrete frames, not interframe long-GOP compression such as used in h264. If you try to sue h264 when sound editing it soon becomes apparent how useless it is when you try to scrub/play video backwards. Interframe compression means the codec is only storing the difference between frames, when moving forwards. So when you try to scrub the video backwards it is very very slow/inefficient. For sound editorial/scoring/dialogue editing MJPEGA or PhotoJPEG codecs are much better codecs to use, as they store discrete frames....

Great Article. Extremely helpful and informative. Well done. Keep more articles like this coming!

another well-written, useful article from jan ozer, thanks... the part about h.264 licensing costs is rather disturbing, especially considering that there isn't any clear cost structure as of yet. for the previous poster, ben balser: it's a well-known fact that the h.264 codec that is implemented in quicktime compressor is inferior, it becomes rather obvious once you start using professional encoding tools, at minimal bitrates.

What? Where did you get information that QuickTime's H.264 encoder is bad? We use it all the time, and find it very top shelf, even compared to other encoding engines. And seeing as how Apple had a major hand in developing H.264, well, I don't see where you get your information. The comparisons we've done in our studio show QT's H.264 to be as good as anyone else. So, at our studio, we're a bit baffled. Great article with that one little misinformation exception.
