Hi there!

I'd like to know how can I remove, for example, built-in subtitles from a video file. I will worry about recognizing letters later, right now I only want to know how can I process a movie frame by frame, and remove pixels from those. Is it even possible using this library? Samples show only how to add something...

This is certainly possible, using the same technique as adding say a time display to a video - you have a bitmap of the frame to edit, so you can add/remove/blur etc.

See this article by Eric Willis showing a blur effect being applied to a region of an image - which you could use to obfuscate a watermark etc.
