Я конвертирую FLV
фильм в GIF
файл с помощью ffmpeg.
ffmpeg -i input.flv -ss 00:00:00.000 -pix_fmt rgb24 -r 10 -s 320x240 -t 00:00:10.000 output.gif
Он прекрасно работает, но выходной GIF-файл имеет очень низкое качество.
Любые идеи, как я могу улучшить качество конвертированного GIF?

ffmpeg -i input.flv -ss 00:00:00.000 -pix_fmt rgb24 -r 10 -s 320x240 -t 00:00:10.000 output.gif
