How to change a generated film without regenerating it
Upload the film you already have and tell Vizard Agent explicitly not to regenerate it. Vizard Agent studies the master frame by frame, detects its exact shot boundaries, analyses its sound design, and fits the new material into the existing cut so everything you liked survives untouched.
What do you type into Vizard Agent?
Put the prohibition first and be emphatic about it. Vizard Agent will otherwise reach for the generator when a change would be easier to generate than to edit, which is usually the right instinct and is exactly what you are ruling out here. Then name what you love about the master, so it isn't traded away for the change.
Prompt
What does Vizard Agent actually do?
When a generated film comes out right, rerolling it gives you a different film. So Vizard Agent treats the master as footage rather than as a prompt: the existing frames stay, and the change is an edit. Most of the time goes on understanding the film well enough to change it without disturbing it. In the session behind this article it:
- Read the project ledger, downloaded all the inputs, and viewed the master frame by frame alongside the real footage supplied.
- Built a contact sheet of the new photos, then zoomed into the film's final seconds to check the ending frames in detail.
- Fetched the photos used in the original master, so a new section could use the same photographs rather than images from another visual world.
- Listened to the real recording, analysed the master's sound design, checked for duplicate photos and identified who was who in the footage.
- Detected the master's exact shot boundaries before cutting anything in, so new material landed on cuts rather than across them.
- Delivered a 1920x1080, 30fps film of 60.01 seconds with the master's lighting, pacing, typography and atmosphere intact and nothing rerolled.
When does this not work well?
Preserving a master limits what a change can be. A scene that doesn't exist yet has to be generated, extending one shot moves everything after it, and real footage against a generated look can show at the join. A colour pass on the master changes it, and reordering a film is a rebuild by another name. Vizard Agent says which requests these are rather than quietly rerolling.
Common questions
Will Vizard Agent regenerate anything? Not if you say not to. Vizard Agent treats the master as footage and edits rather than rerolls.
Can I add real footage to a generated film? Yes. Vizard Agent cuts it in at existing boundaries and can grade it toward the look.
Will the length change? Not unless you ask. Vizard Agent fits changes inside the original duration by default.
