For four distinct outputs, ffmpeg -i input -vf crop=1920:1080:0:0 output1 -vf crop=1920:1080:1920:0 output2 -vf crop=1920:1080:0:1080 output3 -vf crop=1920:1080:1920:1080 output4 (I've ignored audio. The above command will transcode it. Add -c:a copy before each output to avoid that) _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
