How to smooth the jumps where a person changes position at every cut

Last updated 2026-09-22 · 8 min read

What is the short version?

The content is fine and the video twitches its way through. Each time a take was restarted the speaker had moved slightly, and every one of those small differences lands as a visible jump at the cut, which is what Vizard Agent is measuring here.

1. Tell Vizard Agent the position jumps are what needs fixing.
2. Let it find the cuts rather than listing them yourself.
3. Expect the first dissolve length to be too short.

What do you need before you start?

Just the video, in most cases. Vizard Agent detects the cut points itself, and the genuinely useful thing you can add is whether the audio has to stay continuous underneath, because that limits how long a picture dissolve is allowed to run at each join.

• The video. The edited version with the jumps.
• What is jumping. Position, framing, or both.
• Whether the audio is continuous. It usually is.
• How much you mind. Invisible, or just calmer.
• The delivery length. Dissolves consume frames.

What do you type into Vizard Agent?

Describe the symptom in terms of the person. "Tidy the transitions" could mean anything; "his position jumps at each cut, make it look natural" identifies which of the many things a transition could fix is the one that matters here.

Prompt

Variants worth knowing:

• "The person's position jumps." The specific fault.
• "Reads as continuous." The standard to hit.
• "Keep the audio as it is." Picture-only change.

What does Vizard Agent actually do?

Here is the Vizard Agent sequence on a talking-head video that jumped at every single join. The first version gets built, reviewed and then rebuilt with longer dissolves, which is the normal shape of this job rather than a sign that the first attempt failed.

1. Checks the video's duration, size and structure.
2. Samples frames to see how the person's position moves.
3. Reviews the sequence of frames to locate the jumps.
4. Detects the cut points and scene changes precisely.
5. Inspects the frames immediately before and after each transition.
6. Assembles the frames around the cuts into one review sheet.
7. Compares before-and-after frames at each join.
8. Renders a version with a soft dissolve at every cut.
9. Checks the duration and confirms the audio survived.
10. Reviews the rendered frames and the audio's validity.
11. Watches the result at the cut points to judge the smoothness.
12. Re-renders with longer dissolves so the position jumps are better disguised.
13. Re-checks the frames around every transition on the revised version.

Step seven is the step that sets the dissolve length. Two frames side by side tell you how far the person actually moved, and the size of that difference is what decides whether a six-frame dissolve is enough or whether you need twice that.

Step twelve is the honest second pass. A standard dissolve is designed to be barely noticed and therefore barely covers anything; absorbing a real jump in position means a longer one, which is a trade against pace.

Step nine matters because picture-only edits drop audio more often than anyone expects. Checking the track exists after the render is a two-second habit that saves a delivery.

What does the result look like?

The same video with joins that read as movement rather than as errors: the speaker appears to shift naturally rather than teleporting, the audio runs as before, and the runtime is close enough to the original to drop into the same slot.

When does this not work well?

Some jumps cannot be dissolved away. If the person moves a long way between takes, if the background changes, or if they are mid-gesture on both sides of the cut, a dissolve shows both positions at once and looks worse than the jump.

• Large position changes. The dissolve shows two people.
• Changed background. The room appears to melt.
• Mid-gesture cuts. Two arms in different places.
• Very short shots. No frames to spend on a transition.
• Hard-cut styles. Dissolves fight the register of the edit.

How do you fix a result that came back wrong?

Say whether it is still jumping or whether it now looks soft and smeary. Those two complaints pull in opposite directions, so Vizard Agent lengthens or shortens the dissolves accordingly rather than changing its approach to the whole video.

• "It still jumps at 0:14." That transition is lengthened specifically.
• "It looks smeary now." The dissolves are shortened and the worst cut handled separately.
• "I can see two of him." That cut is covered another way, or reframed.
• "The video got longer." The dissolves are absorbed into the shots rather than added between them.

How does Vizard Agent compare to doing it yourself?

By hand you add the editor's default cross-dissolve everywhere and it barely helps, because that default is tuned to be invisible rather than to cover a moving subject. The fix is longer transitions at specific cuts, which means measuring the jumps first.

Common questions

Why not just reframe instead? Sometimes that is better — Vizard Agent can crop each shot to match rather than dissolve.

Will the video get longer? Only slightly, and Vizard Agent can absorb the dissolves into the shots.

Can it fix only the worst cuts? Yes. Name them, or ask Vizard Agent for the list of the largest jumps.

Does the audio change? No. Vizard Agent keeps the original track and checks it afterwards.

What about a jump in framing rather than position? Same approach — Vizard Agent sets the treatment from the measured difference.

Can it use something other than a dissolve? Yes. Vizard Agent can hide a jump with a small push or a whip instead.

Will it work on a vertical video? Yes, and jumps show more there, so Vizard Agent treats them harder.

Can it prevent this next time? Mark your position before you restart a take; that is the real fix.

How long should a dissolve be? Long enough to absorb the jump; Vizard Agent measures the jump rather than guessing.

Does it work with hard cuts elsewhere? Yes. Vizard Agent treats only the jumping cuts and leaves the rest alone.

What if the speaker moves a lot? Then a cutaway is usually better, and Vizard Agent will suggest one.

Can it add B-roll over the joins instead? Yes, if you have footage — that hides a jump completely.

Will the pace suffer? Longer dissolves do slow a cut; it is a trade you can ask to see both sides of.

How do I check it? Step through each cut frame by frame; that is where a dissolve shows two of them.
