  • ffmpeg - "Incompatible pixel format 'rgb24' for codec 'gif', auto-selecting format 'rgb8'"

    8 février 2017, par fordprefect

    I’m trying to convert a .webm to .gif at a pretty good quality, so I decided to have a go at ffmpeg (very new to this). I followed some instructions and did some research and after setting everything up figured out what I wanted in the command line :

    ffmpeg -i input.webm -pix_fmt rgb24 -vf scale=-1:720 output.gif

    Whenever I start the conversion it gives me a warning (as seen in the title), and gives me a somewhat low quality gif by using ’rgb8’. I’ve googled around but can’t seem to find an answer, not that my skill level can understand at least.

    Help would be much appreciated ! Thanks :)

    I tried with other stackoverflow questions but none of them worked. Also I think it is partially because the trim timings are mixed. That is start time can be anywhere between 0-end. When I make it strictly increasing it is working fine.
