ffmpeg how to put color overlay over video
17 novembre 2015, par flieksI 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 ?
