Input #1, png_pipe, from '/tmp/pallete.png': To slow down the, we can use a larger ratio: convert -delay 1x100 respect.gif respect-slow.gifĪnimated GIFs still have a place on the web optimizing their effectiveness remains important.I am using ffmpeg to convert high quality videos to gif, most of the videos are 60fps and over 720p, but when I use the code below, to convert the video to gif, I get very low fps for the gif output, #!/usr/bin/envįilter='fps=50,scale=480:-1:flags=lanczos'įfmpeg -y -i test.mov -vf $filter,palettegen=stats_mode=diff $paletteįfmpeg -y -i test.mov -i $palette -lavfi '$filter paletteuse' test.gifĪnother issue I have noted is - as the width increases e.g 720 instead of 480 I get even lower fps. To speed up the animation, we can use a smaller ratio: convert -delay 1x30 respect.gif respect-fast.gif The ratio returned represents the hundredths of a second between the animated GIF's frames. The first step in modifying a GIF's speed is determining the GIF's root speed to determine this ratio, we'll use ImageMagick's identify command: identify -verbose respect.gif | grep Delay Let's use the following GIF as our sample: With that idea in mind, I set about trying to figure out how to modify the speed of an animated GIF let's explore it! The same could be said about animated GIFs whether they're used as a meme or to illustrate a process, the speed of an animated GIF can effect its effectiveness. Comedians would tell you that timing is the most important part of any joke.
