the console) which is pretty easily processed. This puts the information out to stdout (e.g. The other options above are just to stub off the output. I don't do any of that NFT stuff, but if you want to support what I do here and elsewhere, I'll happily send you a randomly generated token, and moreover be extremely grateful.The blackdetect filter takes in a parameter to indicate the duration period of black frames (d=2) and the threshold of frame 'blackness' pix_th=0.00. Just add the -y parameter into your command and it won’t bother you anymore. One last trick if you’re scripting these commands and you’re constantly having your script stop and ask you if you want to override your previous output gif with a new animation. Of course, the other thing I mentioned last time was that ImageMagic will consistently use so much memory that the process just crashes and fails, whereas ffmpeg never has a problem in that area. Other examples weren’t quite that bad, but ImageMagick always wins handily in the size category. A quick test:Īnd the ffmpeg test included generating the palette as well as the animation.įile size is not so good a story though. Other considerations when deciding whether to use ffmpeg or ImageMagick are rendering speed and file size.įfmpeg will create gifs way faster than ImageMagick. Using these two commands, I was able to get a correctly paletted animation, with no yellow: And apparently, ffmpeg was smart enough to figure out that input 0 was the frames and input 1 was the palette, So I could shorten the entire thing down to : so I could get rid of that whole first action. In my case, I’d already set the framerate. In short, uses the palette image as the palette for the animation. Paletteuse Takes the data in x and uses input 1 (the palette image) as a palette using the paletteuse filter. filter_complex "fps=24,scale=$:-1:flags=lanczos Sets the fps to 24, scales the gif to a given size on x and keeps the aspect ratio on y (the -1 param), uses Lanczos resampling to do the scaling.
