There’re some editing softwares available for windows that help to solve below problem but I have trouble to find a graphic/video editing tool for linux that provide source quality .gif output. Most linux software similar kdenlive, shotcut etc auto detect source file resolution and other essential basics but when export to a file, none of them provide source quality gif file. Usually i can see tiny shaking dots or bit color differences.
In this case, i use .gif file as source (but this must be applicable to .mp4 file formats etc and get source quality output as .gif). Once again i expect to get very smooth and high quality gif.
Shotcut video editor developer said,
Good GIF export requires pre-processing to generate a palette that is rather old and unique in a video format and not available in Shotcut. Most GIF-like things on the web now are actually MP4 or WebM videos, and GIF is very low priority for us.
We do not take feature requests. You can search the web for how to use ffmpeg. For example, GIPHY Engineering | » How to make GIFs with FFMPEG » How to make GIFs with FFMPEG
Our Shotcut builds include ffmpeg.
Above “giphy engineering” link page contain gifs also has mentioned problem as well.
I only found GIMP as solution to that source-quality-output file problem but it isn’t optimized yet for edit gif animation then quite difficult to use
gitlab.gnome[dot]org/GNOME/gimp/-/issues/6133 (one difficulty to use it)
Then is there any tool available on this linux world to solve this problem?
