-e<event_id>, --event=<event_id> - What event to create the video for
|
|
-f<format>, --format=<format> - What format to create the video in, default is mpg. For ffmpeg only.
|
|
-r<rate>, --rate=<rate> - Relative rate , 1 = realtime, 2 = double speed , 0.5 = half speed etc
|
|
-s<scale>, --scale=<scale> - Scale, 1 = normal, 2 = double size, 0.5 = half size etc
|
|
-F<fps>, --fps=<fps> - Absolute frame rate, in frames per second
|
|
-S<size>, --size=<size> - Absolute video size, WxH or other specification supported by ffmpeg
|
|
-o, --overwrite - Whether to overwrite an existing file, off by default.
