h264 has a proablem in that it can look desaturated on screen while look perfect within a compositing app. Something to do with how it looks at monitor color profiles.
Sorenson 3 also loses a lot of color information, though it generates the smallest file and is probably fine for captures where the motion is more integral than color.
Photo JPEG files are heavier than sorenson 3 but seems to have a good combination of good color and compression.
cheers!

Which type I use would depend on what kind of material I am compressing, but I usually use Mpeg4 Video for my work and it provides good quality and reasonable filesizes. I think 264 is superior to that but I have had trouble encoding with 264, so I went back to mpeg4. I always use full quality and fiddle with data rate until I get either the filesize I need for mailing or ftp or a good balance between size and quality required for reasonable viewing.

Subject: OTish - Best Quicktime format for previews
Hello all,
So, who uses what QT format for the best results? What's the flavour of the month?
Recently we've had some people saying Motion JPEG-A is the way to go & others saying "OH no, don't do dat!".
We used to be happy with Sorenson3 'till Motion JPEG-A was brought up.
Or is it H.261, 263 or 264 that gives the best result?
There are bound to be sliding scales but what good balances have been found for colour accuracy & size.
Cheers,
Adam.
