+**--use-timestamp** - If you extract the frames using ffmpeg's __-frame_pts 1__ option, then use this argument to make the bot parse timestamp from the filenames.

 **--verbose** - Turns on verbosity.
 
 **--dry-run** - Testing mode. Bot carries out all the works except making any web request. A dummy response is returned for checking. Dry-run mode turns on verbosity automatically.
