  • Is there a lossy compression option for video to GIF conversion in ffmpeg ?

    3 octobre 2019, par formicini

    I’m trying to achieve a certain minimum file size when converting videos to GIF files, and willing to sacrifice video quality to get to that size if it’s required.

    I have tried the usual stuff : reducing framerate and resolution. Reducing color palette’s max_colors gave no noticable loss in file size.

    My current code :

    ffmpeg -i in.mp4 -filter_complex "fps=3,split[s0][s1];[s0]palettegen[p];[s1][p]paletteuse[s2];[s2]scale='min(200,iw)':'min(200,ih)':force_original_aspect_ratio=decrease:flags=lanczos" out.gif

    I know using another tool like gifsicle or ImageMagick is an option, is there any built-in way in ffmpeg to reduce output quality in order to lose file size ?

  • How to add compression to ffmpeg command

    13 septembre 2019, par balfred

    I am trying to add a good level of compression to the following ffmpeg command or if it is already good can you help me understand ?

    I have seen that people might have luck using this command but I dont know how to merge it into mine

    ffmpeg -i sourceFilePath -vcodec h264 -acodec mp3 newFilePath

    This is my current command that I am using that I need help understanding why the previous command might be a better solution but how to implement my additional arguments

    ffmpeg -i sourceFilePath -vcodec libx264 -profile:v baseline -level 3 newFilePath

    I want to see optimal compression and still have my existing functionality using my additional arguments. I dont know what will produce the best results, this is out of my area of expertise.
