why go to mp4? I usually do the following
file: export: quicktime movie (not quicktime conversion) with current settings
Take this file into compressor
use the apple: formats: quicktime: h264 preset and customize by adjusting the video setting in the encoder panel by moving the quality slider to high.
Depending on the duration of the file, that usually gets a reasonably sized file with pretty good quality. If the file size is too big, I'll adjust the pixel dimensions to 720 in compressor.
One friend told me dont choose none of the three options...
Told me about exporting a reference movie from timeline and then take the reference file into compressor.
I finally took the reference file and took him to compressor. I installed x264 and got one .mov very heavy, so I had to use the handbrake to get less weight and get mp4.
I did the same operation in streamclip and got a mp4 file (x264) with same size than .mov (compressor). So in both cases, if I want the less size I have to go on 2 steps (first compressor or streamclip and then handbrake ..)
any more suggestions? :-)
