When I see a trailer in .mov format the quality is usually DVD-like and the files are the same size as avi's and the avi's have a slightly lower quality, so why have have that bit extra?:01:

Probably because it's proprietary format...
I'm not so sure about avi has lower quality...

.mov files won't play on stand-alone DVD players.

If you try converting from .mov format to .avi format there's an additional loss in quality during the conversion which doesn't occur if you convert from the original source, but of course people who don't have the original don't have that option.

But what about now that the new codec is coming to windows soon... h.264

The difference should be huge.. i hope ppl will code with that codec... it seems to be over divx , xdiv and all the codecs we have known.

its not xdiv, its xvid :) (divx, backwards. get it? hahaaha :P)

and yes, H.264 is fantastic, but I like open source codecs more (xvid ;))

A well made xvid (mpeg-4) formatted video has DVD-like quality. Along with vbr lame mp3 audio there is very little other formats I find out there that can beat that combo that are free/gpl or even ones that are "commercial" can`t.

vbr ... audioNO! NO! NO!

Never try to combine vbr audio into an avi video stream, it simply doesn't work properly.

Avi indexing is done purely on the video stream, and consequently it assumes that the audio stream is synchronised. But most (all?) avi combiners assume that the audio stream is at least a(average)br, and consequently treat it as cbr. With abr the result is some loss of audio sync. If vbr is used audio sync is often totally out of the window.

Considering that the difference between vbr, abr and cbr for 1hr of video is usually well under 10MB (assuming reasonable bitrates) there seems little point in suffering loss of audio sync for the compartively minor drop in video bitrate required to achieve the same file size.

ok then. It works for me here... sometimes :wacko:

I do usually VBR for short videos and CBR for long ones.

Anyone have any idea how to incode a movie with H.264
I can't even find the codec. I thought I could just use QuickTime Pro 7
but QT is very piky about what kind of movie files I can open.
I'm LOST!
