Yes, because filter combinations with only one input and one output apparently aren't complex. (I wasn't aware of that.) See below. > ffmpeg -i input.mp4 -c:v libx264 -filter_complex > "scale=640:-1,split=2[v1][v2]; > [v1]crop=200:306:456:0,lutyuv=y=val*0.75[brightpart]; > [v2]lutyuv=y=val*2.5[darkpart]; > [darkpart][brightpart]overlay=x=456:y=0[v]" -map "[v]" -c:a copy > -threads 2 -crf 20 -f mp4 output.mp4 Use the same as above with "-vf", drop the "[v]" at the end. The map then refers to the demuxed input streams, so either omit it, or use "-map 0:v": $ ffmpeg -i input.mp4 -map 0:v -c:v libx264 -vf "scale=640:-1,split=2[v1][v2]; [v1]crop=200:306:456:0,lutyuv=y=val*0.75[brightpart]; [v2]lutyuv=y=val*2.5[darkpart]; [darkpart][brightpart]overlay=x=456:y=0" -c:a copy -threads 2 -crf 20 -f mp4 output.mp4 Moritz _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user
