![]() Gifsicle -resize _x90 -colors 256 -color-method diversity -dither=ordered -resize-method sample input.gif > output. gifsicle -i anim.gif -O3 -colors 256 -o anim-opt.gif This will optimize and reduce to 256 colors, if the animation uses more colors (the example image does). ![]() Replace input.gif and output.gif with the input and output file names, and 99 with the number of frames in your animation. 2 Answers Sorted by: 81 Use gifsicle (available for Mac OS X, Windows, DOS, Debian, FreeBSD and NetBSD). We tried tweaking colour quantization in gifsicle as well but it was of no use. Here's a simpler solution using gifsicle than JohnB's script: gifsicle -U input.gif seq -f 'g' 0 2 99 -O2 -o output.gif This command should work in most Unix shells I've tested it in bash. Paletteuse=dither=bayer:bayer_scale=5:diff_mode=rectangle We even tried changing dithering algorithm to further reduce size but it ended up adding noise and damaged the gif quality using ffmpeg version 4.1.4īut we observed a huge difference in size between the gif we created and the one created using tenor.įfmpeg -i input.mp4 -filter_complex "fps=10,scale=-1:90:flags=lanczos,split palettegen paletteuse" -y output.gif Now we wanted to create our own gifs and are using the following command to convert mp4 to gif while maintaining the properties of tenor's nano gif. Gifsicle is 10x faster than our previous converter. We used to embed tenor nano gifs(90px height maintaining aspect ratio, used for GIF previews and shares on mobile) in it. Gifsicle is a powerful, simple command line tool for creating, editing, and optimizing animated.
