Animated gif to avi on linux

Question

Is there any way to convert an animated gif to a video format (e.g. .avi), on linux?


p.s. i have already tried ffmpeg's
ffmpeg -i thegif.gif thevideo.avi
but all i get is the first image of the video.

Answer 1

I can suggest combination of imagemagick and ffmpeg

do this to extract each frame as png/jpeg

$magick> convert 'images.gif[0]' image.png

Do this to convert images to movie sequence

ffmpeg -f image2 -i image%d.jpg video.mpg

Answer 2

ffmpeg's gif input doesn't work too well. It's usually easier to unpack the gif frames with convert (from ImageMagick) and process these with ffmpeg:

convert some.gif some%05d.png  
ffmpeg -i some%05d.png some.avi  
rm some*.png
