View specs and play first clip

ffprobe clip1.mov
ffplay clip1.mov

Deinterlace

ffplay -i clip1.mov -vf "bwdif=1"

Crop video to 16:9 Ratio

ffplay -i clip1.mov -vf "bwdif=1,crop=in_w:in_w*9/16"

Center crop and align to top

ffplay -i clip1.mov -vf "bwdif=1,crop=in_w:in_w*9/16:(in_w-out_w)/2:0"

Scale SD video to 720p*

ffplay -i clip1.mov -vf "bwdif=1,crop=in_w:in_w*9/16:(in_w-out_w)/2:0,scale=1280:720" -aspect 16:9

*added “-aspect 16:9” to fix problem with non-square pixels

Pad and scale (This is an alternative to crop and scale)

ffplay -i clip1.mov -vf "bwdif=1,pad=in_h*16/9:in_h:(in_w-out_w)/2,scale=1280:720" -aspect 16:9

Prepare for Concatination

files.txt:
file ‘clip1.mov’
file ‘clip2.mov’
file ‘clip3.mov’

Concat (join) multiple video files

ffplay -f concat -safe 0 -i files.txt -vf "bwdif=1,crop=in_w:in_w*9/16:(in_w-out_w)/2:0,scale=1280:720" -aspect 16:9

Save output as H.264 mp4

ffmpeg -f concat -safe 0 -i files.txt -vf "bwdif=1,crop=in_w:in_w*9/16:(in_w-out_w)/2:0,scale=1280:720"  -aspect 16:9 -pix_fmt yuv420p -ss 00:00:0.0 -t 10 out.mp4

Look at available H.264 encoders

ffmpeg -codecs | grep 264

Save output as H.264 mp4 with hardware encoding (on Mac)

FFmpeg documentation on hardware accelerated encoding

ffmpeg -f concat -safe 0 -i files.txt -vf "bwdif=1,crop=in_w:in_w*9/16:(in_w-out_w)/2:0,scale=1280:720" -aspect 16:9 -pix_fmt yuv420p -vcodec h264_videotoolbox -ss 00:00:0.0 -t 10 out2.mp4

Compare software and hardware encoded files

ffprobe out.mp4
ffprobe out2.mp4

Hardware encoding with higher bitrate

ffmpeg -f concat -safe 0 -i files.txt -vf "bwdif=1,crop=in_w:in_w*9/16:(in_w-out_w)/2:0,scale=1280:720" -aspect 16:9 -pix_fmt yuv420p -vcodec h264_videotoolbox -b:v 5400k -ss 00:00:0.0 -t 10 out.mp4

Speed up video

ffmpeg -f concat -safe 0 -i files.txt -vf "bwdif=1,crop=in_w:in_w<em>9/16:(in_w-out_w)/2:0,scale=1280:720,setpts=1/7</em>PTS" -aspect 16:9 -an -pix_fmt yuv420p -vcodec h264_videotoolbox -b:v 5400k -ss 00:00:0.0 -t 10 out.mp4

Output final video (without audio)

ffmpeg -f concat -safe 0 -i files.txt -vf "bwdif=1,crop=in_w:in_w<em>9/16:(in_w-out_w)/2:0,scale=1280:720,setpts=1/7</em>PTS" -aspect 16:9 -an -pix_fmt yuv420p -vcodec h264_videotoolbox -b:v 5400k final_without_audio.mp4

Merge final video with audio without re-encoding video

ffmpeg -i final_without_audio.mp4 -i Rolling_Hills.mp3 -vcodec copy -acodec aac -b:a 128k -map 0:v:0 -map 1:a:0 final_with_audio.mp4
