Where 100 is the desired amount of vertical pixels you want to offset from right to left, shifting the image toward the right:įfmpeg -i /path/to/input.mov -filter_complex 'overlay=100:0 overlay=100-W,format=yuv420p' -map '' -an -codec:v libx264 -crf 23 -preset medium /path/to/output.FFmpeg can be used to encode videos into difference formats.

c:a or -c:v = refers to a command relating to the codec, so if you want to copy one of those codecs you can write: -c:v copy which is passthrough for video Commands Remove Audio:įfmpeg -i input.mp4 -c:v copy -an output.mp4 Extract Audio (use preferred codec):įfmpeg -i video.mp4 -vn -c:a copy -acodec pcm_s16le output.wav Add Audio To Video:įfmpeg -i input.mp4 -i input.wav -c:v copy -c:a aac -b:a 320k output.mp4įfmpeg -i input.mov -i input.wav -c:v copy output.mov Adjust the Volume (percentage or db works) :įfmpeg -i input.mp4 -vcodec copy -af 'volume=-15dB' -b:a 320k output.mp4 Adjust Length to the shortest audio or video:įfmpeg -i input.mp4 -i audio.aac -shortest -c:v copy -c:a copy output.mp4 Scale a video for performance:įfmpeg -i input.mp4 -s 1920×960 output.mp4 Scale a video by video filter for reducing size:įfmpeg -i input.mp4 -vf scale=iw*.5:ih*.5 output.mp4 Convert to DNxHD for Pro Toolsįfmpeg -i input.mp4 -c dnxhd -s 1280x720 -r 24000/1001 -pix_fmt yuv422p -b 90M OUTPUTNAME.mov 360 Video Manipulation Stereoscopic to Monoscopic: Over-under (top-bottom):įfmpeg -i input.mp4 -vf crop=h=in_h/2:y=0 output.mp4 Side-by-side (left-right):įfmpeg -i input.mp4 -vf crop=h=in_w/2:y=0 output.mp4 360 Video Rotation

b:a or -b:v = bitrate, great for reducing a HQ video to work on mobile (example: -b:v 20m) an or -vn = remove either audio or video Some common audio/video related flags or arguments to FFmpeg commands and what they mean.
