  FPS reduction for H264 - Александр А Newest 'ffmpeg' Questions - Stack Overflow
  There is a USB camera that sends H264 frames with a frequency of 30 fps in a resolution of 1920x1080, GOP size 30 or 60 (1 or 2 I frame per second depending on the camera), which requires throughput of about 6 mbit/s.

  How to batch process with ffmpeg script, but do each step in a loop instead of two stages - Matt Newest 'ffmpeg' Questions - Stack Overflow
  I'm a novice script editor. I convert MOV/AVI video files to MP4 format using a script with ffmpeg and then move the files after processing: for f in *.mov; do ffmpeg -y -i "$f" "$f%.mp4"; done mv -f *.mov /Users/me/Videos/mov mv -f *.MOV /Users/me/Videos/mov mv -f *.avi /Users/me/Videos/avi mv -f *.AVI /Users/me/Videos/avi Currently the script converts all videos, then moves them all to the other folders. Please how can the script be adjusted so that each video is moved immediately after processing (instead of waiting until all are complete)? (...)
