Automatically generate optimised palettes for animated GIFs

[SleepyCatten]

Hi folks

At present, Shotcut doesn’t generate optimised palettes for animated GIFs. This can be worked around by exporting the output as a video file, then running it separately through FFMPEG, as a lovely user pointed out here:

Increasing exported GIF quality doesn't remove artifacting or increase quality or increase file size

Settings I’ve tried: quality-based VBR at 100% quality constant bitrate (maxing all values) constrained vbr (maxing all values) average bitrate (maxing all values) Resulting output (uncompressed file host): https://lensdump.com/i/0TL9XA What gives? I want a bigger file size (my host size limit is up to 8 megabytes for GIF and I want to utilize almost all of it so that I can have a better quality image). I’m thinking I’m doing something wrong because the resulting file is always the same siz…

For high-quality GIF conversion, consider exporting the Shotcut video as Ut Video Lossless, then use FFmpeg to generate an optimized palette. The command looks like this:

ffmpeg -i Input.mp4 -filter_complex “[0:v] split [a][b];[a] palettegen [p];[b][p] paletteuse” Output.gif

If this could be incorporated into Shotcut for all animated GIFs, it would make the program a one-stop-shop for creating high-quality animated GIFs, avoiding the need for other programs.
