Reset = Determines after how many frames cropdetect will reset the previously detected largest video area and start over to detect the current optimal crop area. Round = Ensures the output resolution is divisible by the value specified. You can play around with that, it worked mostly well for me with the default value 24 Limit = The threshold of the intensity of the black bar. The cropdetect filter is configured with the arguments cropdetect=limit:round:reset with the following meaning: Or using FFmpeg with a command line like ffmpeg -i YourMovie.mp4 -vf "cropdetect=24:16:0" dummy.avi This can be done using the command line ffplay -i YourMovie.mp4 -vf "cropdetect=24:16:0" This can be done by FFplay using the cropdetect filter. Let’s have look how we can do it the easy way using FFmpeg.Īt first we need to find out the necessary values for the cropping filter. Ok, before you leave the keyboard and stop reading.
In this article i’ll show you how to do this with FFmpeg. If you’ve ever been in a situation where your recorded video had a blank interval or you just want to get a specific part of your video you’ll definitely want to crop your video.
