Crop

Hello.

What does it mean that crop mod-2, mod-4, mod 16 etc???

It means that the image dimensions in pixels after cropping are divisible by that number. That means it's supposed to be an integer, no something point something.

For example the number 640 is mod16 (which implies that it is also mod8, mod4 and mod2). 640/16 = 40
360 is not mod16: 360/16 = 22.5
But 360/8 = 45 so it's mod8.

I have a movie in 1200x790 as I should have cropped in mod2

But i can't get the right number i should crop.

1200x790 is mod2 (mod2 is easy: any even number is mod2).
But that is a pretty weird size. We need a sample (image or video).

I found out that I just had to resize and my problem away.
