A small script that appends CRC-32's to every mkv in the current directory.

generate_keyframes

Generic script to generate keyframes for all files of a given extension. Heavily inspired by kagefunc's generate_keyframes, but made to work as a standalone script for timers. Special thanks to begna for helping me with writing big parts of this.

Argument	Arg	Description
--help	-h	show this help message and exit
--recursive	-R	check recursively
--extension	-E	pick extension to generate keyframes for
--noheader	-N	do not include header line for aegisub
--outfile	-O	name for keyframes file output
--trims	-T	string of trims to source file. format: "[inclusive,exclusive],[inclusive,exclusive],[None,exclusive],[inclusive,None]"

Usage Example:

Trim one second off of the start and end

$ python generate_keyframes.py -T "[24,-24]"

Trim three seconds off of the end

$ python generate_keyframes.py -T "[None,-72]"

Trim the first five seconds

$ python generate_keyframes.py -T "[120,None]"

remux
