- -dither strength
- Specify a dithering strength between 0 and 100. Dithering is a
post-processing effect applied to chroma components in lossy compression.
It helps by smoothing gradients and avoiding banding artifacts. Default:
50.
- -mt
- Use multi-threading for decoding, if possible.
- -info

other options afterward will be ignored. If the input file is
"-", the data will be read from stdin instead of a
file.
KEYBOARD SHORTCUTS¶
