How to get the stray hands out of a generated sequence
Tell Vizard Agent which shots have people in them and ask for the hands to be edited out of the stills rather than the shots regenerated. It cleans each affected image, checks the cleaned frame before it goes anywhere near the timeline, and then animates from the cleaned versions, so the sequence keeps the composition you already approved.
What do you type into Vizard Agent?
Ask for an edit rather than a regeneration. The composition, lighting and style of the shot are already right, and the only thing wrong with it is a pair of hands. Regenerating throws away everything that worked to fix the one thing that did not. Say "no people at all" as a rule for the whole piece.
Prompt
What does Vizard Agent actually do?
Some words quietly summon people into a shot. Ask for planting, harvesting, unboxing or applying, and the picture comes back with hands in it, because the action implies a person. Vizard Agent edits the hands out of the stills and cleans before it animates. The job was a vertical short about a plant's growth stages, built as nine generated shots. In the session behind this article it:
- Inspected the shots and reviewed the two with hands at full size, the two whose descriptions involved a person doing something.
- Checked which editing method suited each frame, since a method that works on flat soil will smear a detailed background.
- Cleaned the affected stills to remove the hands, then checked the cleaned first shot and the cleaned last shot.
- Confirmed the rest of each frame was unchanged, because an edit that removes hands can quietly redraw the subject underneath.
- Generated the animations from the cleaned stills and sampled them for visual continuity.
- Rebuilt the sequence with the cleaned shots in place.
When does this not work well?
Some frames cannot lose their people, and Vizard Agent will tell you which ones. If a hand is holding the subject, occluding most of it, or is the reason the composition works at all, removing it leaves a hole that has to be invented from nothing rather than simply uncovered. Already-animated shots are harder too: clean before animating, not after.
Common questions
Can I just say "no people"? Yes, up front. Vizard Agent applies it to every shot.
Will editing damage the picture? It can. That is why Vizard Agent checks each cleaned frame.
Is regenerating ever better? Sometimes, and Vizard Agent will say when the occlusion is too big.
