ffmpeg - adding white background to complex png command
5 août 2022, par Uriel RomanoI have a complex concatenation of commands working perfectly :


ffmpeg -r 24 -i "D:\batches\S3025C-SV_"%%03d.png -vf "scale=out_color_matrix=bt709,eq=gamma=1:saturation=1,fps=25, crop=trunc(iw/2)*2:trunc(ih/2)*2" -color_primaries bt709 -color_trc bt709 -colorspace bt709 "D:\batches\S3025C-SV.mp4"


Now I need to add a white background to this mp4 render, as ffmpeg is using a black one by default. I've found the following command here :


-filter_complex "[0:v] setpts=PTS-STARTPTS [graphs]; [1:v][graphs] overlay=shortest=1 [out]" -map "[out]"


How could I combine this operation into the first one ? I've tried a couple of different syntaxes but couldn't get it to work.


Thanks for your help !
