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. For our longer gifs, this method cut our file size down by about 40. You might need to fiddle with the params and the dithering methods to achieve best result. 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 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 (Also, there's no such things like "huge" pixels, they are the atomic elements of raster images.) Bilateral blur, non-linear, edge-preserving, and noise-reducing smoothing filter. For best results, I'd recommend floyd_steinberg or sierra2_4a, and maybe bayer with scale set to 3. create a GIF animation sequence from a group of images. 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. ffmpegexample.gif - The resulting output file. The above GIF was generated with this tool. Assumes ffmpeg command is globally available. r 10 - Set the frame rate to 10 to reduce the overall size. A small script that converts videos to a high quality GIF, by spawning ffmpeg in two passes using palettegen filter. Shell_exec("/usr/bin/ffmpeg -i video.mkv -r 20 -f image2pipe -vcodec ppm - | convert -delay 5 - output.gif") vf subtitlesffmpegexample.srt - Run a video filter (vf) over the input, this one being the subtitles filter with the file containing the subtitle information.
