New very good codec test in Computer Magazine

[sirbender]

Ther german most respected computer magazine c't has tested 10 of the most recent codecs very intensively - also a H.264 codec - I haven't read it yet but it looks promising.

I don't like that comparison, it's more about web-streaming (most bitrates are rather low and the bit/pixel values are kept in the <15 range) and they obviously see nothing wrong with sacrificing details for less macro-blocks (rather than looking at it as trade-off where you have to find the best balance)

Most of it seems tweaked to let XviD perform as bad as possible - I don't think that it's intent, their articles about video encoding were always rather amateurish compared to the rest of the magazine

sirbender: Mh, as stated in the article - the settings for xvid and the decodes where done by the xvid team (as the have asked the developers of each codec (giving to them the test-sources) what would be the best settings in that circumstances) - so you can say the setting was worse for xvid (wich is a strange argument because it ended up as one of the best - and IMHO the setting was well choosen (even if I would have wished for the rating for archiveable backups)), but not the tweaking....

Well, for that test some trade offs were to make:

- to reach the demanded low bitrate at all
- to keep something of xvid's nature, ... details.

Thus I didn't tweak the avisynth script too much.
As i stated in the according thread on general discussion forum, Volker from the c't wanted to test real hard scenarios to better make visible where the codecs "belong".

The test isn't amateurish at all, believe me. It's just not about things we do here... the result is more useful for amateurs and web-streamers.

And I repeat what I as well wrote already on "the other thread": XviD isn't made for such scenarios. It could be tweaked for that, but then the "usual encodes" we're talking about here would look bad. (As doom9 wrote: it would be possible to tweak xvid to behave like RV9...)

It's already very good that xvid anyways can play in that league.

Actually, I am very happy about Xvid's Position in the field. IMO it is really on its way to become the equivalent to LAME in the field of video compression. Once again proving the power of open source development. I like it!
