At any rate, the example I used looks as if it's just taking 10 pixels, and the person who answered the person asking the question just told them to look at the manual for more details. I'm not sure what I'm missing here, but I suspect it's pretty obvious. (If anyone is kind enough to look at the man page for me, just search for in_w on the page and the crop section begins above it.) I understand that by using in_w and/or in_h with no arguments, one just uses the original width or eight, but I'm not sure how the h-10 takes 20 pixels off the bottom. The man page refers to taking equal amounts off top and bottom. I'm not sure how one designates top and bottom with the new syntax. However, I'm confused as to why it works. Now, one uses -vf crop= and some syntax that I am not getting. Say I wanted to take 20 pixels off the bottom, it used to be -cropbottom 20. I'm having trouble understanding the new version of ffmpeg cropping syntax.
