Which type of program editor should I use to edit both movie files such as avi or mpeg and svg files? I have tried inskape, I guess that is only for svg files and not movie files.
Which editor should I use?
They’re completely different things. Use a different editor.
It’s like asking why you can’t open an Excel spreadsheet in Photoshop, or why you can’t open PowerPoint files using YouTube: it ain’t gonna work I’m afraid.
