How to know when to stop masking and regenerate the shot
Let Vizard Agent work through the masking options before deciding, because whether a shot is maskable is a finding rather than a guess. When the thing you want gone is visible through a full rotation, the mask usually fails, and rebuilding the movement is the honest alternative — with its own defect to check for.
What is the short version?
You want something removed from a shot where the subject turns all the way round. Masking is the cheap answer and it may simply not work here, because the object changes shape, lighting and occlusion on every frame of the turn. Vizard Agent finds that out and then changes approach.
- Ask Vizard Agent to remove it and let it try the masking routes.
- Accept it if the answer comes back that the shot is not maskable.
- If the motion is rebuilt, check the end of the move specifically.
What do you need before you start?
The clip, and a clear statement of what must not change. "Remove this and keep everything else exactly the same" is the version that keeps masking on the table; if you would also accept a rebuilt shot, say so, because that changes which routes are worth trying at all.
Know what else is wrong with the shot. In the session behind this article the spin also reversed direction halfway through, and that second problem is the one that made regeneration attractive rather than merely acceptable.
What do you type into Vizard Agent?
Describe the removal and the movement together in one brief. A removal request that does not mention the rotation gets answered by Vizard Agent as though the object sits still, and then the first attempt fails for a reason nobody planned for and nobody learns anything from.
Remove the grey hood entirely so it does not appear at all, and make the spin go in one direction instead of reversing. Keep everything else exactly the same.
That last sentence is worth keeping even though it is the thing most likely to be renegotiated. It tells Vizard Agent to exhaust the conservative options before proposing anything that replaces your pixels.
What does Vizard Agent actually do?
It runs an escalation rather than picking a method. Each rung is cheaper and more faithful than the next, so the order matters: the first thing that holds across every frame wins, and the ladder itself is the diagnosis.
In that session the attempts went:
- Made a closer, frame-by-frame view of the spin and analysed its direction and the object's timing.
- Tried targeted object removal, then object segmentation to isolate the fabric.
- Built a tracked mask, extracted its alpha channel, and inspected a raw mask frame for usable coverage.
- Refined the tracked mask, then tried a broader one, and previewed the detected coverage.
- Tested a local fill on the isolated area, and looked for clean neighbouring poses for a frame-accurate patch.
- Tried a still-frame removal and two localised crop repairs on the upper body.
None of it survived the full rotation. So the approach changed: the movement was regenerated hood-free and in one direction, with a clean end pose prepared first, and the original audio re-attached afterwards.
What does the result look like?
A shot that does what you asked, built rather than repaired. The object is genuinely absent instead of patched over, the turn goes one way, and the original audio sits on top of the new motion in sync.
What you have given up is the original pixels. That is the real cost of this route and it is worth naming — the subject is now a rebuilt version of themselves, which is fine for some purposes and not for others. Vizard Agent names that trade rather than letting you discover it afterwards.
When does this not work well?
When the original footage is the point. A rebuilt shot is no longer a record of what happened, so anything documentary, evidential or personal is better left with a visible flaw than replaced with a convincing substitute, and Vizard Agent will say which of the two you are choosing.
Regenerated motion also fails at the extremes of a move. In that session the first generated version put the head the wrong way round at the end of the spin, which had to be regenerated with anatomically consistent head motion and then verified at that exact point.
And a cheaper generation setting shows. The user's own reading was that the lower-cost option was a false economy, and on a shot with a full rotation in it that is usually right.
How do you fix a result that came back wrong?
If the anatomy breaks, say where in the move it breaks. The extremes of a rotation are where it usually happens, and Vizard Agent regenerates with that constraint named in the brief rather than trying the same settings again and hoping for a luckier result.
If the masking nearly worked, ask which rung got closest. Sometimes a frame-accurate patch from neighbouring poses covers the worst few frames and the rest holds, which keeps most of your original pixels.
If the audio drifts against the new motion, that is a separate fix. Vizard Agent re-attaches the original track and verifies the sync rather than regenerating anything further.
How does Vizard Agent compare to doing it yourself?
A compositor would run the same ladder and reach the same conclusion, and the value is in reaching it quickly rather than spending a day on a mask that was never going to hold. Knowing a shot is unmaskable is a real result.
The part worth copying is checking the regenerated version at the extremes of the movement, which is where Vizard Agent looks first. A rebuilt turn looks fine in the middle and comes apart at the ends, which is exactly where nobody thinks to scrub to.
Common questions
Why is a rotation so hard to mask? Because the object changes shape, lighting and occlusion on every frame of the turn.
Will it tell me masking failed? Yes. Vizard Agent reports that the shot is not maskable rather than delivering a poor patch.
What does regenerating cost me? The original pixels. Vizard Agent will say so before it proposes it.
Can it keep my audio? Yes. Vizard Agent re-attaches the original track and checks the sync.
Where does generated motion break? At the extremes of the move. Vizard Agent checks the end of a turn specifically.
Should I use a cheaper generation setting? Usually not on a full rotation. The saving rarely survives the review.
Can part of the shot be masked and part rebuilt? Sometimes. Ask Vizard Agent which frames the mask actually held on.
What if I need the real footage? Then keep the flaw. A rebuilt shot is no longer a record of what happened.
Does it try the cheap options first? Yes. Vizard Agent works up the ladder from the most faithful method.
How many attempts is reasonable? Enough to exhaust the ladder. That is the diagnosis, not wasted effort.
Can it fix the spin direction as well? Yes, and that is easier to do in a rebuild than in a repair.
Will the subject still look like themselves? Approximately. Vizard Agent compares against the original and will flag drift.
What about the end pose? Prepared first, so the new motion has somewhere to land.
Can I see the failed masks? Yes. Ask Vizard Agent for the coverage previews it built.
