colors messed up (distorted) when making a gif from png files using ffmpeg
13 novembre 2019, par wxyzI have a sequence of png images :
image_00.png,image_01.png,image_02.png, etc. I want to convert them to a gif, so I tried the commandffmpeg -i image_%02d.png video.gifUnfortunately, the resulting gif has distorted colors. More specifically, it added a weird sort of yellow haze around some objects in the video.
I also tried using the command above with all possible pixel format options (which I determined using the command
ffmpeg -h encoder=gif) :rgb8,bgr8,rgb4_byte,bgr4_byte,gray,pal8. For exampleffmpeg -i image_%02d.png -pix_fmt rgb8 video.gif. Unfortunately, all of the resulting gifs had some sort of color distortion.I also observed that this distortion does not occur if I convert the images to mp4 instead of gif. However, if I try converting that mp4 to a gif, I end up with the distortion again.
How can I produce this gif without color distortion ?

Washed colors with ffmpeg in macOs
18 décembre 2020, par GabrielleI am having problems regarding the colors of a screen recorded video generated by ffmpeg on mac.




I am using the following command to generate the video :


ffmpeg -f avfoundation -video_size 1980x1140 -framerate 30 -capture_cursor 1 -capture_mouse_clicks 1 -i '1' -preset ultrafast -an -qp 0 -crf 22 -pix_fmt yuv420p -y -c:v libx264 -c:a libfaac -vf eq=brightness=0.00:contrast=1:saturation=1 video_test.mkv


I tried to change
qpto 1 and 2, to change thecrfto 0 and 2 (let it higher and lower than qp), tried to usepix_fmtyuv444p and bgr0 and 0rgb, tried to changec:vto libx64rgb, tried to not usevfbut the result is the same.

The only real difference I've noticed is when I put a really high crf that makes the image very pixelated...


I've tried different numbers for brightness, contrast and saturation but I couldn't find a good combination.


Any idea how to make the video look more as the original ?


Full log :




About the red message in the middle of the image, this is always printed even when I use yuv444p (the red message prints yuv420p)
