http://unix.stackexchange.com – I have about 300 videos, on a Debian server, stored in the following manner: /mediaroot/1/m32.mp4 /mediaroot/2/m421.mp4 /mediaroot/n/mx.mp4 They all need to be deinterlaced, and I want to do it with FFmpeg. With the assistance of another helpful sole, I have reached a somewhat tolerable result with the following steps: extract audio transcode video, example ffmpeg -y -i m148.mp4 -pix_fmt yuv420p -an -pass 1 -passlogfile m148.x600.1351896878.log -an -vcodec libx264 -b:v 600k -preset medium -tune film -threads 0 m148.x600.1351896878.mp4 ffmpeg -y -i m148.mp4 -pix_fmt yuv420p -an -pass 2 (HowTos)
