If it's 2-3x of native code, that's plenty good enough. Everyone uses Handbrake in an async mode - just set up the conversion and let it run overnight. Of course, a website would be better for smaller conversion jobs (in case you have browser restarts or whatnot). Desktop apps can block computer restarts to a greater degree than websites.
