First passes
- AI masks and tracking give a quick first pass. Edges, hair, motion blur and fast movement still need a person.
- Object removal works best on small, simple things. Check every frame for smears and flicker.
Checking
- Play the shot at speed, then step through frame by frame. Look at edges, hair and anything crossing the mask.
- Log what was AI and who checked it.
Who signs off
- The compositor, then the VFX supervisor. On a small job, the editor or colourist who owns the shot.
Check
3 questions drawn from 8 · pass mark 80% · safety-critical questions must be right · 3 attempts in 24 hours · new questions each time

Do
Plan a clean-up · 20 minutes
A boom pokes into the top of a shot for 40 frames while the actor walks past a window. Plan the clean-up: tools, checks and sign-off.
How it's marked
- Tries reframing or another take first
- Uses AI removal or a mask as a first pass
- Checks edges, the window and motion frame by frame
- Logs it and names the sign-off
Met or Not yet, with a comment from a trained reviewer. Until accounts open, open the model answer after you submit and mark your own work against it.
Model answer (open after you submit)
First check for another take or a reframe. If not: AI removal on the boom, with a mask to protect the actor's head; step through all 40 frames for smears near the window frame and hair; fix by hand where needed. Log 'AI removal, checked by [name]'; compositor and VFX supervisor sign off.
