eli5: Why is rotoscoping (in video editing) so hard ? why can’t you just draw a new mask from scratch on every frame ?
In: 1
I mean, you could draw a new mask every frame…. But that’s even MORE difficult. That’s drawing 24 masks every second.
When rotoscoping, you set a mask with points, and every frame you drag those points to match the object you are rotoing. I think dragging points is way easier than drawing all the points again.
