How to move the camera in a generated shot without the scene moving too
Tell Vizard Agent that the camera is the only thing moving, and name the things in the scene that must stay as they are. A generated camera move is still a generated shot, so it animates whatever it contains: the subject takes a step, and anything that was knocked over quietly resets itself to standing.
What do you type into Vizard Agent?
List for Vizard Agent the things that should stay still. It reads as pedantic when you write it out, and it is the entire difference between a camera move and a new shot: anything you leave off the list is something the generator is free to animate.
Prompt
What does Vizard Agent actually do?
A camera move sounds like a purely geometric request and isn't. The generator is producing new frames, and new frames contain a scene that has to be decided again, including the parts you'd already established. So the move starts from a real frame, and the subject and objects are locked one by one. In the session behind this article it:
- Prepared a matching reference frame, created the side profile as a still first, animated the move into it and added the new beat after the original ending.
- Reviewed the three-angle sequence as a whole, then took the original front-on frame as the orbit's starting point.
- Generated a true orbit rather than a cut to a new angle. The first orbits were geometrically correct, but the world inside them was still alive.
- Regenerated the orbit with the subject and the objects locked, and verified there was no walking and no reset in the final cut.
- Removed the seam while keeping the angle change, so the join didn't show. It took three attempts in all.
When does this not work well?
Large moves invent more. A small orbit around a subject can be anchored to what's visible; a move to the far side of the room has to generate a wall nobody has seen, and the state of the scene there is a guess. Complex scenes have more state to hold still, and freezing a subject mid-action looks unnatural.
Common questions
Why does the subject move at all? Because the frames are being generated. Vizard Agent has to be told to freeze them.
What should I list as locked? Anything whose state matters. Vizard Agent holds a spill, a broken thing or an open door.
Can it do a full orbit? Short ones hold up best. Vizard Agent will say where invention takes over.
