You're trying to accomplish something incredibly complex straight out of the block there. Video editing is a bit of a fine art and one that's a lot harder than you might think.
If you've got the know how, time, knowledge and patience, then there's no reason you can't do video editing in VB
, but I'd suggest it's not a practical language for this purpose (and it sounds like your skill level isn't really up to this sort of task in any language.)
Think a bit more simply for now - try and make something like a calculator. It'll still have a fair amount of challenges, but without the technical complexity of what you're trying to achieve at present.
