  • ffmpeg how to put color overlay over video

    17 novembre 2015, 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 ?
