![]() ![]() 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. Everything is OK, only in several video, the result is 'Pixelated' or small squares appear on the picture. ![]() The screen resolution of the flv and mpg files are exactly the same (ie 320x240 pixel). You might need to fiddle with the params and the dithering methods to achieve best result. I had converted several hundreds flv video to mpg using ffmpeg. 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 Before you start it is always recommended to use a recent version: download or compile. 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.) ![]() 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") ![]()
