Hi friends, have any of you encountered this use case? Using Rails 5 on a project to do this and wasn't able to find anything on StackOverflow. Hoping to convert an mp4 to an animated gif using ImageMagick. Any help is greatly appreciated, or just a point to a tutorial or the right direction. Many thanks!

I believe to be able to convert mp4, you need ffmpeg loaded where ImageMagick could find it. If that is available, then the following should work in the command line. Sorry I do not know Rails.
Code: Select all
convert -delay X image.mp4 -loop 0 animation.gif
If that does not work, then try
Code: Select all
convert -delay X image.mp4 -coalesce -layers optimize -loop 0 animation.gif
Where X is the desired frame delay in ticks (1/100 s)

Please, always provide your IM version and platform when asking questions, since syntax may differ. Also provide your exact command line and if possible your images.
