How to put your own pet into a video in place of the one that is there
Give Vizard Agent photographs of your pet and say the animal in the video should be replaced by it rather than added alongside it. It studies how the original animal moves and substitutes yours into the footage using your references. Where the clip has more than one animal, it finds the exact frame the change happens so only the one you meant is swapped.
What do you type into Vizard Agent?
Use the word "replace" and then tell Vizard Agent what should happen to any other animals in the clip. That second half matters more than it looks: a clip that cuts to a different animal halfway through will otherwise have both of them changed into yours. Send several photos from different angles, in reasonable light.
Prompt
What does Vizard Agent actually do?
The original animal's movement is the performance, the way it lands and the way its tail goes, so Vizard Agent builds the replacement onto that rather than generating it fresh. It surveys the footage first, because you can't replace a subject reliably without knowing how many subjects the clip contains. In the session behind this article it:
- Looked at each reference photograph and surveyed the source video shot by shot.
- Studied the sections containing the cat to be replaced, and watched its movement in detail before attempting anything.
- Checked which capability suited replacing a subject in footage, fed the original video in as the basis, and substituted the owner's cat from the reference pictures.
- Compared source frames with replaced frames side by side, to see whether the movement survived.
- Found the exact frame where the second cat took over, left that animal untouched, and finished the swap.
When does this not work well?
A replacement follows the original's body. If your pet is a very different size or shape, such as a small dog standing in for a large one, the movement won't sit convincingly on it, and the result reads as the original animal wearing your pet's colours. A different species is usually too far, fast or blurred movement leaves little to anchor the likeness to, and on long clips the likeness drifts.
Common questions
How many photos should I send? Two or three from different angles. Vizard Agent will say if it needs more.
What if there are two animals? Say which is which. Vizard Agent finds the frame where they change over.
Does my pet need to be the same colour? No. Vizard Agent takes the colour from your photos, and a similar build matters far more.
