Split padding fields to vertical/horizontal

[chrisdola]

It would be incredibly helpful to split out the padding fields to horizontal & vertical to allow for more custom sizing by default. As it stands now, the only way to handle this after the fact would be editing the mp4 to crop the size once it's done.

I already made the changes locally and can submit a PR.. Just wanted to get input before submitting it. 😊
