I tried a couple of 720p exports using compressor, but it took in excess of three hours! to export an 8 minute video.
I must admit i’ve never really used compressor before, is it usually this slow.
I’ve done a couple of tests this afternoon, exporting as a final cut ProRes 720 quicktime, then compressing to h264 in streamclip it’s it’s nigh on impossible to tell the difference between the compressor version and the streamclip version.
