gif speed is very fast

[owenclements]

Hi all, I am a Linux user in which I have used the "convert" command to get a list of images from a .mov file and converting those images into a .gif.

While the process works, whenever I used the ImageMagick application to open the .gif files, the speed that it is playing the .gif is very fast, and there is a need for me to click on the "speed" button followed by the "slower" option so as to match the speed with the .mov.

My question would be wow can I check or ensure that the .gif animation is playing at its 'supposed' speed/ framerate? (Using either the Faster/ Slower speed does not seems to assure me that I am converting my .gif animation correctly..)

What was your command to convert the files to gif? Did you include -delay XXX. See https://imagemagick.org/Usage/anim_basics/ and https://imagemagick.org/script/command- ... .php#delay

What is your Imagemagick version?

I don't think IM will automatically set the delay rate. You can get this from ffmpeg or ffprobe:

Code: Select all

ffprobe ball4.mov
:
:
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'ball4.mov':

This movie is 25 fps, so "-delay 4" should work.
