I've got a bunch of videos I've uploaded to STP and the original videos have a large black border around them. Is there a way to crop off those black borders automatically with the encoder?

Goodwill at Smart-Scripts told me there is NOT a function for cropping off black borders yet when I tested it out by uploading to YouTube it strips the black border off before making it live... Anyone know what I need to do?

no one has any ideas?

If you know the number of pixels you want to chop off the borders, it's easily done. Just use ffmpeg.

As for having it detect the black border, I'm sure it's possible, but don't know exactly how. Would need to research that one. But chopping borders of videos is no problem, assuming you know the number of pixels you want to chop.

Would that be a universal thing if I added it to ffmpeg? It's only on the exclusive videos I've uploaded so I don't need to crop everything

"Black borders" can mean a lot of different things? Are there borders around the entire video, or just the top/bottom and left/right?

YouTube has a zoom function that can be applied to zoom in the entire image. Their encoder may be auto-detecting the black space if there are borders around the entire video frame?

Any decent encoder can crop (same as zoom) X pixels form the tops and sides. Whether or not you want to use FFmpeg depends on the format you're encoding to. It does a sloppy job with some formats, like FLVs (sadly that's what most people use it for).

It's literally a black box with a video inside it so it's on all sides.
