  • ffmpeg how to put color overlay over video

    13 mai 2020, par flieks

    I want to put a color overlay (blue, red or green or hex value) over a video giving it a Instagram filter like effect.

    



    I think it should be in the lines of :

    



    ffmpeg -i video.mp4 -i "red.png" -filter_complex "blend=all_mode='screen':all_opacity=0.7" output.mp4


    



    or maybe with all_mode=overlay

    



    But I get an error :

    



    First input link top parameters (SAR 0:1) do not match the corresponding second input link bottom parameters (SAR 1:1).


    



    I also tried with lutrgb=r=1.5, but that didn't give it a red color (it takes the red away).

    



    What am i doing wrong ?

    of matching color space to ensure the color space information to be
    correctly passed from encode to decoder in compressed vp9 streams.
