It has a crop filter that lets you pick any frame you want and crop to that, but it also has a VERY good auto-detect button that almost always detects the edges correctly (the exception is very low light scenes, but you can use a slider to pick a brighter frame). Generate a video by removing duplicate frames from input video using ffmpegįfmpeg -i input.mp4 -vf mpdecimate,setpts=N/FRAME_RATE/TB out.Well since others have mentioned their favorite alternatives to plain ffmpeg for this task, I'll just mention Avidemux. Filter a video to get duplicate frames in a video using ffmpegįfmpeg -i input.mp4 -vf mpdecimate -loglevel debug -f null -ġ2. Split a video into multiple segments of equal in length or approximately equalįfmpeg -i input.mp4 -c copy -map 0 -segment_time 8 -f segment output%03d.mp4ġ1. Split a video into multiple segments at key frames using ffmpegįfmpeg -i input.mp4 -f segment -vcodec copy -reset_timestamps 1 -map 0 output%d.mp4ġ0. Insert few black frames to an input video using ffmpegįfmpeg -i input.mp4 -f lavfi -i 'color=c=black:s=1080x1920:r=25' -filter_complex ' setpts=PTS-STARTPTS trim=end=10,setpts=PTS-STARTPTS concat=n=2:v=1:a=0 ' -map '' -vcodec mpeg2video -maxrate 30000k -b:v 30000k output.mp4ĩ. Generate video with only black frames, using ffmpegįfmpeg -t 60 -s qcif -f rawvideo -pix_fmt rgb24 -r 25 -i /dev/zero dummy.mp4Ĩ.

Change the resolution of the video using ffmpegįfmpeg -i input.avi -vf scale=320:240 output.aviįfmpeg -i 'concat:input1.avi|input2.avi|input3.avi' -c:a copy output.aviħ. Calculate PSNR/SSIM from input video and reference video using ffmpegįfmpeg -i input.mp4 -i rf.mp4 -strict -2 -filter_complex 'psnr' 'output.mp4'ĥ. Cut specific portion of video using ffmpegįfmpeg -ss 24 -i input.mp4 -t 25 -c:a copy out.aviĤ. Extract individual frames from a video using ffmpegįfmpeg -f rawvideo -framerate 25 -s 352x288 -pixel_format yuv420p -i akiyo_cif.yuv out%03d.png or ffmpeg -i input.mp4 -vf fps=25 out%d.pngģ. Crop specific portion of video using ffmpegįfmpeg -i input.mp4 -filter:v 'crop=1080:560:0:650' -c:a copy out.aviĢ.
