Short answer: rotoscoping (isolating people or objects frame by frame) and cleanup (removing unwanted things) used to be among the most time-consuming VFX tasks. AI tools now produce first-pass mattes and fills in a fraction of the time. They still need a human pass on edges, motion blur, hair and consistency across frames, that is where shots are won or lost.
Typical cleanup jobs
- Wires, rigs and safety equipment.
- Logos, signs and brand names that were not cleared.
- Crew, reflections of cameras, modern objects in period scenes.
- Blemishes and small continuity errors.
What AI does well
Separating a person from a background in clear footage, filling a removed area with plausible texture, and tracking the fill through a moving shot. For many shots this turns hours of manual work into a review task.
Where humans still check
- Hair and fine edges, especially against busy backgrounds.
- Motion blur, where a fast arm is part person, part background.
- Temporal consistency: fills that change slightly from frame to frame cause shimmering.
- Reflections and shadows of the removed object.
Shoot to make it easier
Clean plates, tracking markers where needed, and avoiding unnecessary logos on set all reduce cleanup. Learn more on the AI VFX page.
Frequently asked questions
What is rotoscoping?
Isolating a person or object in every frame so it can be separated from its background, colour-corrected or composited.
Can AI remove logos from footage?
Yes, in many cases. Complex shots still need a human pass to avoid shimmering or leftover reflections.
Does AI replace VFX artists for cleanup?
It speeds up the first pass. Edges, motion blur and frame-to-frame consistency still need expert review.
