How to change how far a movement goes without breaking the motion

Last updated 2026-09-10 · 8 min read

Tell Vizard Agent which movement should go further and by how much. It rebuilds only the window of frames that contains that movement, narrows the window when a seam starts to show, stitches it back with the original audio, and then checks the frames on both sides of every boundary against the original's own clean motion.

What is the short version?

Changing how deep a squat goes, how high a jump reaches or how far a door opens is a change to a few dozen frames, not to a shot. Rebuild the whole shot and everything else drifts; rebuild the window and the only risk left is the two joins.

Go to Vizard Agent with the clip.
Say which movement and how much further.
Say the scene and framing must not change.

What do you need before you start?

The clip and a description of the movement in ordinary terms. You do not need to give a percentage or an angle — "a bit lower", then "a tad lower still" is a perfectly workable way to converge, because each round costs only the window rather than the shot.

The clip at its original quality.
Which movement. By what the person is doing.
How much further. Roughly is fine.
What must not change. Scene, framing, clothing, audio.
Whether it must be one continuous motion.

What do you type into Vizard Agent?

Name the action and the direction. This is a request that converges over two or three short rounds, so the first message does not need to be precise — it needs to be about the right thing, which is the movement rather than the shot.

Prompt

Make the squat a bit lower. Keep everything else the same — the same scene, the same framing, the same person, the original audio. It should read as one fluid movement, not something that changes partway down.

Variants worth knowing:

"A bit lower." Converges faster than a number.
"One fluid movement." Rules out a mid-motion seam.
"Keep the original audio." It should not be regenerated.

What does Vizard Agent actually do?

Here is the order Vizard Agent worked in on a real clip whose movement had to go further. The second half is the same operation done again on a narrower window, which is what fixes the seam the first attempt left behind.

Samples frames to see how far the movement currently goes.
Checks the timing of the action before editing anything.
Checks whether the tools support a pose change rather than only retiming.
Checks the options and the price before committing.
Prepares only the section containing the movement.
Rebuilds that section with the movement extended, scene preserved.
Checks the new section for continuity, framing and whether it looks natural.
Views the edited section beside the original for comparison.
Recombines it with the untouched parts and the original audio.
Prepares a shorter window focused only on the lowering and the bottom.
Regenerates that narrower window with no extra scene changes.
Inspects the replacement before stitching it in.
Stitches it into the original footage with continuous audio.
Inspects the frames immediately around both boundaries.
Rechecks the movement at higher sampling to confirm the change.
Compares the middle of the edit against the original's clean motion.

Step ten is the move that fixes the glitch. A wide rebuilt window has more frames in which the generated motion can drift away from the real one, so narrowing it to the part that actually has to change reduces both the cost and the amount of movement that can go wrong.

Step fourteen is the check that matters more than watching it. A seam lives in two or three frames at a boundary, which plays in a tenth of a second, so the boundaries are examined as frames rather than judged at speed.

What does the result look like?

The same shot with the movement now going as far as you asked, still reading as one continuous action, with the scene, the framing and the person left unchanged around it by Vizard Agent and the original audio still running underneath.

Compared against the original, the only difference is the thing you asked to change.

When does this not work well?

The movement has to be the only thing changing. If the camera moves during the action, if something passes in front of the subject, or if the change is large enough to alter the whole body's balance, the rebuilt window stops matching what surrounds it.

A moving camera. The window and the shot diverge.
Something crossing the frame. It has to be rebuilt too.
Very large changes. Balance and shadow stop matching.
Fast movements. Fewer frames to work with.
Loose clothing or hair. These are hard to keep consistent.

How do you fix a result that came back wrong?

Say whether it is the amount or the smoothness, and roughly where. Vizard Agent keeps the window and the comparisons, so going further is another short pass and a glitch is a narrower window rather than a fresh attempt at the whole shot.

"Still not far enough." Another pass on the same window.
"It glitches partway." The window narrowed and rebuilt.
"The clothing changed." Rebuilt with tighter preservation.
"You can see the join." The boundaries re-checked frame by frame.

How does Vizard Agent compare to doing it yourself?

The usual approach is to regenerate the shot with a better description, which produces a different shot rather than the same one with a deeper movement. It also throws away the framing and the audio you already had, so each round moves several things at once.

	By hand	Vizard Agent
What gets rebuilt	The whole shot	The window with the movement in it
Everything else	Regenerated too	Untouched
A seam in the motion	Accepted or restarted	The window narrowed
Checking	Watching it back	Frames at both boundaries
Converging	Each round is expensive	Each round costs a window

Common questions

Can it change only the movement? Yes. Vizard Agent rebuilds the window, not the shot.

Will the person still look the same? That is the point of the narrow window; Vizard Agent preserves the scene.

Can I ask for "a bit more" repeatedly? Yes, and Vizard Agent finds that converges faster than numbers.

What causes the glitch in the middle? A window wider than it needs to be. Vizard Agent narrows it.

Does the audio change? No. Vizard Agent keeps the original track underneath.

Will the framing move? No, unless the change is large enough that Vizard Agent has to.

Can it do this to real footage? Yes. Vizard Agent applies the same window logic to filmed footage.

What about several movements in one clip? Yes. Vizard Agent handles each as its own window.

Can I see before and after? Yes. Ask Vizard Agent for the two sections side by side.

How small can the window be? Just the frames that change. Vizard Agent finds smaller is safer.

Will shadows match? Vizard Agent checks them; large changes make it harder.

Does it cost a full regeneration? No. Vizard Agent rebuilds only the window.

Can it make the movement smaller instead? Yes. Vizard Agent works in both directions.

Why not just describe the shot better? Because a better description produces a different shot, and what you wanted was this shot with one thing changed.
