Answer by alijandro for How do I convert a video to GIF using ffmpeg, with reasonable quality?

The answer from @Stephane is very good. But it will get a warning like Buffer queue overflow, dropping. for some video, and the generated gif has some frame dropped.

Here is a better version with fifo filter to avoid Buffer queue overflow when using paletteuse filter. By using split filter to avoid the creation of intermediate palette PNG file.

ffmpeg -i input.mp4 -filter_complex 'fps=10,scale=320:-1:flags=lanczos,split [o1] [o2];[o1] palettegen [p]; [o2] fifo [o3];[o3] [p] paletteuse' out.gif
