Why h264?
maziyarutei:
err, im not really familiar with this place so please forgive me if it's obvious, how do i know which file is coded using h.264? just want to see the difference between h.264 and XviD. anyway im glad that l-e ambraced h.264, im always up for good crystal clear movie quality. i've just downloaded quicktime 7 for windows, going to see check out h.264 trailers real soon....

Just watched Space Symphony Maetel, encoded using h264.
I was blown away by the quality. Very impressive!
It uses between 11-15% of one core on my A64 X2 4200.
That would be about 22-30% of a single core A64 3500.
I would like to try encoding something with this.
That would require some horsepower!
I will look around, if anyone has any recommended links, I wouldn't object.. ;)
I remember when it would occasionally be asked if a system had enough power to play back a MP3...
JL:
Is h264 the PSP codec? If I should ever get PSP will this ep of Maetel play on it? Just about to install the required codec/players for my pc...

A quick test, not by any means very scientific:

The xvid actually used 2% more CPU power to render than the h.264 for the same exact resolution.
20% of 3.2 Ghz is the equivalent of about 800 Mhz, so even a high PIII should be able to render it properly (unless your system is so full of spyware that you have no system resources left, in which case you have more problems to worry about :P).
Anyway, all I am saying is, the idea of h.264 using an insane amount of CPU to render is a myth. It uses no more CPU than xvid :X

That can't be true, because I never had syncronisation problems, wait problems when I hit the timeguage to skip 20 minutes...
It really consumes much more than xVid does, I got a notebook over here and you really see the different.
By the way, if someone knows how to get rid of the synchronisation problem, tell me will ya, because when the opening song ends I just started to see the intro.

I've only been around long enough to remember the time when xvid went 1.0. There was on particular situation with a series where the group switched from xvid 0.9 to xvid 1.1. This meant that everyone had to upgrade their codecs. It caused NO END of trouble. However once people stopped complaining and giving up they were able to play the file after having upgraded their codecs.

Hehe, your right, I can see why people wants to use this codec, still it's hell to get the right codecs upto date.
