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.) 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. Gifski is described as macOS app for the gifski encoder, which converts videos to GIF animations using pngquants fancy features for efficient cross-frame palettes and temporal dithering.It produces animated GIFs that use thousands of colors per frame and is a animated gif creator in the photos & graphics category. Install npm install -save puppeteer-lottie Renders Lottie animations via Puppeteer to image, GIF or MP4.Shell_exec("/usr/bin/ffmpeg -i video.mkv -r 20 -f image2pipe -vcodec ppm - | convert -delay 5 - output.gif") On macOS, you can run: brew install gifski If you want to generate GIFs, you must also install gifski. On macOS, you can run: brew install ffmpeg If you want to generate MP4s, you must also install ffmpeg. Render the first frame of the animation as a JPEG image Output: 'frame-%d.png', // sprintf format Render each frame of the animation as PNG images with height 128px Create a GIF with width 640px from a lottie animation Usage const renderLottie = require('puppeteer-lottie') MAC GIFSKI INSTALL If you don't pass width or height, the animation's intrinsic size will be used, and if that doesn't exist it will use 640x480. If you pass width or height, the other dimension will be inferred by maintaining the original animation's aspect ratio. If both width and height are passed, the output will have those dimensions, but there will be extra whitespace (or transparency if rendering PNGs) due to lottie-web's default rendererSettings.preserveAspectRatio of xMidyMid meet ( docs and demo).įor mp4 outputs, the height may be different by a pixel due to the x264 encoder requiring even heights.
