-a --audio_params FFmpeg audio settings flags (Default: copy audio from source to output)
Example: -a '-c:a libopus -b:a 64k'
-w --workers Overrides automatically set number of workers.
Example: rav1e settings " ... --tile-rows 2 --tile-cols 2 ... " -w 3
-w --workers Override number of workers.
--resume If encode was stopped/quit resumes encode with saving all progress
Resuming automatically skips scenedetection, audio encoding/copy,
spliting, so resuming only possible after actuall encoding is started.
/.temp folder must be presented for resume.
--no_check Skip checking numbers of frames for source and encoded chunks.
Needed if framerate changes to avoid console spam.
By default any differences in frames of encoded files will be reported.
--keep Not deleting temprally folders after encode finished.
-log --logging Path to .log file(By default created in temp folder)
--temp Set path for temporally folders. Default: .temp
-cfg Save/Read config file with encoder, encoder parameters,
FFmpeg and audio settings.
-ff --ffmpeg FFmpeg options. Applied to each segment individually.
Example:
--ff " -r 24 -vf scale=320:240 "
-fmt --pix_format Setting custom pixel/bit format(Default: 'yuv420p')
Example for 10 bit: 'yuv420p10le'
Encoding options should be adjusted accordingly.
