I took an 18 GB ProRes 422 24 minute master and made two H.264 transcodes -- one in Compressor v.3.0.5 and one in MPEG Streamclip v.1.9.1.
Size results:
Compressor: 1.63 GB
MPEG Streamclip: 750 MB
I can understand there would be some variation, but over
twice the size in Compressor. Does that mean that Compressor is doing a better job - or perhaps a worse one?
I am also curious that with Compressor running QMaster on all 8 cores of my Mac, it took far longer to transcode than with MPEG Streamclip running normally. Unfortunately I didn't time it.
What's going on?
Lost in space,
