1.1 Crop video with dimension 640x360 into video with dimension 202x360 (cropped part should be centered relatively the main video):
ffmpeg \
-i ./media/cmd01/input.mp4 \
-vf "crop=x=219:y=0:w=202:h=360" \
./cmd01_out_01.mp4
You may also use the short version of command and skip parameters name, but you need follow the right order of parameters according to doc:
ffmpeg \
-i ./media/cmd01/input.mp4 \
-vf "crop=202:360:219:0" \
./cmd01_out_01.mp4
1.2 Crop a landscape video into a portrait video with aspect ration 9x16 (cropped part should be centered relatively the main video):
ffmpeg \
-i ./media/cmd01/input.mp4 \
-vf "crop=x=(in_w-ow)/2:y=0:w=in_h*9/16:h=in_h" \
./cmd01_out_02.mp4
At first we need to crop landscape video into partrait with aspect ratio 9x16 and after horizontally flip it
ffmpeg \
-i ./media/cmd02/input.mp4 \
-vf "crop=x=(in_w-ow)/2:y=0:w=in_h*9/16:h=in_hhflip" \
./cmd02_out.mp4
ffmpeg \
-i ./media/cmd03/laptop_stream.mov \
-i ./media/cmd03/stage_stream.mp4 \
-i ./media/cmd03/logo.jpg \
-filter_complex "[0][1:v]overlay=x=W-w:y=H-h:shortest=1[screenWithStage];[screenWithStage][2]overlay" \
