ffmpeg -i in.mp4 -filter:v "crop=out_w:out_h:x:y" out.mp4

# Where:

#     “in.mp4” refers to the input file to be converted
#     “out.mp4” is the name of the output file to be saved after conversion
#     out_w is the width of your desired output rectangle to which the original video’s width will be reduced
#     out_h is the height of your output rectangle to which the original video’s height will be reduced
#     x and y are the position coordinates for the top left corner of your desired output rectangle

# If you want to crop a 1280×720 rectangle from a 1920×1080 resolution video with a starting rectangle position of 10, 10; your command would be:

ffmpeg -i in.mp4 -filter:v "crop=1280:720:10:10" out.mp4
