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. When comparing Gifski and FFMPEG-gif-script-for-bash you can also consider the following projects: video2gif - A batch script for convert video to GIF files by FFmpeg. You might need to fiddle with the params and the dithering methods to achieve best result.
FFMPEG VS GIFSKI HOW TO
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 Use Gifski (Homebrew Package) to Convert a Video File to a Gif Image Macro Library video, image, gifski, homebrew, shellscript cdthomer January 24, 2022, 4:34pm 1 Howdy folks, I've been trying to learn some how to work with shell scripts lately, so I've been making great use of Homebrew packages to make some basic macros.
FFMPEG VS GIFSKI FULL
Share your clips in their full quality, not a bland dithered mess. 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 lets you resize animations and tweak compression levels, so you can make your GIF s fit within upload file size limits. Gifski makes smooth GIF animations using advanced techniques that work around the GIF formats limitations. If you want to reduce the video dimensions, add a scaling filter: ffmpeg -i video.mp4 -vf scale400:240 frame04d. (Also, there's no such things like "huge" pixels, they are the atomic elements of raster images.) ffmpeg -i video.mp4 frame04d.png gifski -o clip.gif frame.png It generates good per-frame palettes, but also combines palettes across frames, achieving even thousands of colors per frame.
FFMPEG VS GIFSKI WINDOWS
For best results, I'd recommend floyd_steinberg or sierra2_4a, and maybe bayer with scale set to 3. Simple batch scripts for making gifs from videos on Windows based on FFmpeg and Gifski - GitHub - qwe321qwe321qwe321/vid2gif-ffmpeg-gifski: Simple batch. If gifski is not installed, the rendering will be much slower than using the gifskirenderer() and can potentially result in system problems when many frames need to be rendered (if gifski is installed magick will use it under the hood) avrenderer() which requies the av package and uses ffmpeg to encode the animation into a video file. 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. Not sure if you or someone else have tested to see if there is a difference of size ( and quality maybe ) of the output gif using the 2 methods. Shell_exec("/usr/bin/ffmpeg -i video.mkv -r 20 -f image2pipe -vcodec ppm - | convert -delay 5 - output.gif") related to above : is ffmpeg 'piping' directly the video to gifski or decomposing the input video into png's frames internally before feeding gifski.
