Comparison of Quicktime (mov) compressions::

Adobe Premier was used for testing

MPEG-4 video or MotionJPEG-B at higher quality, or sorrento3.
File size-wise, MPEG4 is the smallest (e.g. 770k), then Sorrento3 (963k) MotionJPG-B (1231k) is the largest.

sorento (2)
- limit data rate to 100kb/sec
- "quality" does not really matter, 30% is almost equal to 100%
--> small structures disappear.
--> contrast becomes high. 10 point texts cannot be resolved.

sorento3
limit data rate to 100kb/sec
"quality" does not really matter, 30% is almost equal to 100%
---> best quality

MPEG-4 video
-- very poor quality, with "quality" at 30%. at 70%, OK.
-- file size is incedibly small.

MJPG A or B (motion JPEG)
-- vertical lines appear after compresion with 30% quality.
-- with 70% quality, small structures are resolveable.File size becomes more than two times the 30% file.
