Dear list,
I 'd like to encode a video as Quicktime Animation with compressor 
quality at 100%.
this is my command line:

./ffmpeg -i MLM_LT_%*.jpg -s 1280x720 -vcodec qtrle -r 25 test.mov

The result is smaller and worse than the result from QT pro.

Settings in QT Pro are:
fps: 25
keyframe every 24 frames
colors 16,7
quality: optimal

Which parameters do I have to add.
Many thanks,
Sascha
