Repeat options for multiple tracks. For each track at most one of -k, -c or -p can be specified. Counting starts at 0. -k TID, --keep-pitch TID change tempo of track TID while keeping the pitch -c TID, --no-keep-pitch TID change tempo of track TID without keeping the pitch -p TID, --passthrough TID do not filter track TID -s TID:FPS, --sfps TID:FPS assume source FPS for track TID License: refps.py by Alexander Blinne alexander@blinne.net mediainfo.py by AndreFMi...@gmail.com https://code.google.com/p/medianav/ Both published under GPL v3, see COPYING
