You may also try to generate new palette for each frame, so you can skip the first pass, and use the new option in the paletteuse filter. If you have ffmpeg installed, you can run in terminal: ffmpeg -i video.webm frame04d.png and then make the GIF from the frames: gifski -o anim.gif frame. The recommended way is to first export video as PNG frames. You might need to fiddle with the params and the dithering methods to achieve best result. There is no GUI for Windows or Linux (there is one for macOS). Then, use this color template to generate the actual gif file: ffmpeg -i -i palette.png -filter_complex "fps=10 scale=500:-1:flags=lanczos paletteuse=dither=sierra2_4a" -t 10 ![]() Good compression Gifski lets you resize animations and tweak compression levels, so you can make your GIF s fit within upload file size limits. hookffmpeghtml() uses FFmpeg to convert images to a video hookgifski() uses the gifski to convert images to a GIF animation hookscianimator() uses the JavaScript library SciAnimator to create animations hookr2swf() uses the R2SWF package. (tested on M1 CPU, so YMMV) The latest version performs LZW encoding of frames in parallel, and avoids using most of gifsicle codebase except the lossy LZW compression part. Share your clips in their full quality, not a bland dithered mess. With the -fast flag gifski is now about as quick as ffmpeg in wall-clock time, but still generates files that are smaller and look better at the same time. On the other side, you can achieve better results with ffmpeg only.įirst, I'd generate a palette of the input video: ffmpeg -i -filter_complex "fps=10 scale=500:-1:flags=lanczos,palettegen=stats_mode=full" -t 10 palette.png Gifski makes smooth GIF animations using advanced techniques that work around the GIF format's limitations. Gifski also requires us to have ffmpeg to convert video to PNG images. (Also, there's no such things like "huge" pixels, they are the atomic elements of raster images.) Gifski lets you resize animations and tweak compression levels, so you can make your GIF s fit within upload file size limits. This program is capable of creating animated GIFs that use thousands of colors per frame. For best results, I'd recommend floyd_steinberg or sierra2_4a, and maybe bayer with scale set to 3. I suppose you have no imageMagick installed on your environment, because "convert" is one of IM's tools.Īs for the video artifacts, it is caused by the default dithering method in FFmpeg. ![]() Shell_exec("/usr/bin/ffmpeg -i video.mkv -r 20 -f image2pipe -vcodec ppm - | convert -delay 5 - output.gif")
