I'm using MSP13 to remove a few seconds of audio from an MP4 file. When I thereafter use the Make Movie feature and select to save it to my hard drive, the resulting MP4 file is many times larger than the original file. (My goal is to generate a replacement MP4 file that will be accessed from a Plex Media Server.)
I used Handbrake to reduce the resulting MP4 file down to ~1/6-th the original size. The only apparent difference is that the Video Data Rate and Total Bitrate are ~1/7-th and ~1/6-th smaller (respectively) and the Audio Bitrate is reduced from 192kbps to 160 kpbs.
Is there a way I can do this more efficiently?
