FFmpeg

Régler les niveaux d'une vidéo

ffmpeg -i input.mov -filter_complex "colorlevels=rimin=0.19:gimin=0.29:bimin=0.24:rimax=0.76:gimax=0.91:bimax=0.87" output.mov

Combiner deux vidéos

ffmpeg -i contrast.mp4 -i IMG_2918.mov -filter_complex "[0:v] format=rgba [bg]; [1:v] format=rgba [fg]; [bg][fg] blend=all_mode='multiply':all_opacity=1, format=rgba"  combined.mp4

Avec décalage de la deuxieme video

ffmpeg -i contrast.mp4 -itsoffset 3 -i contrast.mp4  -filter_complex "[0:v] format=rgba [bg]; [1:v] format=rgba [fg]; [bg][fg] blend=all_mode='multiply':all_opacity=1, format=rgba"  combined.mp4

Avec de la rotation

ffmpeg -i contrast.mp4 -itsoffset 3 -i contrast.mp4  -filter_complex "[0:v] hflip,vflip,format=rgba [bg]; [1:v] format=rgba [fg]; [bg][fg] blend=all_mode='multiply':all_opacity=1, format=rgba"  combined.mp4

Coloriser l'image

ffmpeg -i combined2.mp4 -i noir.png -filter_complex "[0:v] format=rgba [bg]; [1:v] format=rgba [fg]; [bg][fg] blend=all_mode='screen':all_opacity=1, format=rgba"  combined_screen_noir.mp4
