gif speed is very fast

Post by 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 and ... .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

Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '':
    major_brand     : qt
    minor_version   : 512
    compatible_brands: qt
    creation_time   : 1970-01-01 00:00:00
  Duration: 00:00:00.04, start: 0.000000, bitrate: 374 kb/s
    Stream #0:0(eng): Video: mpeg4 (Simple Profile) (mp4v / 0x7634706D), yuv420p
, 32x32 [SAR 1:1 DAR 1:1], 228 kb/s, 25 fps, 25 tbr, 25 tbn, 25 tbc (default)
      creation_time   : 1970-01-01 00:00:00
      handler_name    : DataHandler
This movie is 25 fps, so "-delay 4" should work.
