I'm trying to convert a .mov to a .gif and I'm not having success.

Here's the error:

ffmpeg -pix_fmt rgb24 -i yesbuddy.mov output.gif

If I leave out the -pix_fmt rgb24 part it complains. Thoughts on how to fix?

FYI, There is an excellent solution for high quality conversions given here. –  shootingstars Mar 28 at 13:37

The order of command line arguments matters. This command line should work but will generate a giant file:

ffmpeg -i yesbuddy.mov -pix_fmt rgb24 output.gif

Note that you probably want to reduce the frame rate and size when you convert, as well as specify a start time and duration. You probably do not want to convert the entire file at its original resolution and frame rate.

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

The file size will still be huge. You may be able to use ImageMagick's GIF optimizer to reduce the size:

convert -layers Optimize output.gif output_optimized.gif

Awesome answer, thanks :) GIF is a crazy format... the original .mov was 250k, the converted .gif from ffmpeg was 8mb, and the convert-optimized version was an astounding 10k! Impressive! –  TooTallNate Jan 22 '13 at 1:37

ffmpeg complains about the pixel format, and switches from rgb24 to pal8; should the command in the answer be updated? –  user1071136 Mar 17 at 20:39
    
Incompatible pixel format 'rgb24' for codec 'gif' –  Andy Jul 18 at 10:15
