How to stop a dissolve showing two of the same person
Tell Vizard Agent you can see two of the same person at the transitions. It replaces the dissolves between shots of one speaker with brief black-edged transitions that never show both frames at once, times each one against the speech so nothing lands mid-word, and checks the joins on the delivered file rather than in the timeline.
What is the short version?
A dissolve blends two frames together. Between two different scenes that reads as a transition; between two shots of the same person it reads as two heads overlapping, and the effect people call ghosting is simply both faces being visible at once.
- Go to Vizard Agent with the cut.
- Say you can see two faces at the joins.
- Say you still want it smooth rather than hard cuts.
What do you need before you start?
The cut and a description of what you are seeing. "Ghosting", "two heads" and "it doubles" all describe the same thing, and any of them is enough — the useful extra detail is whether you want smoothness kept or would accept straight cuts.
- The cut with the transitions in it.
- Where you see it. Roughly, or everywhere.
- Whether smooth still matters. Usually it does.
- How the speech runs. Continuous, or with gaps.
- The delivered file, not just the preview.
What do you type into Vizard Agent?
Describe the symptom to Vizard Agent rather than naming a transition you want instead. Asking for "no dissolves" gets you hard cuts everywhere, which solves the ghosting perfectly and throws away the smoothness you added the dissolves for in the first place.
Prompt
Variants worth knowing:
- "Two of me overlapping." Names the artefact.
- "Keep it smooth." Rules out hard cuts everywhere.
- "On the delivered file." Where transitions really live.
What does Vizard Agent actually do?
Here is the order Vizard Agent worked in on a real promo cut together from four separate excerpts of the same presenter. The dissolves get added deliberately partway through and then taken out again once their cost becomes visible, which is the usual arc for this fault.
- Transcribes the presenter so the cuts follow real sentences.
- Views the selected frames as one sheet to check the presenter stays consistent.
- Prepares the subtitle timings and a short music bed.
- Cuts the excerpts into one continuous story with gentle reframes.
- Renders the promo with the mixed audio, labels and end card.
- Checks the frames, the placement and the loudness.
- Traces a silent tail at the end card and patches the music.
- Rebuilds with short dissolves to smooth the speech joins.
- Has the uploaded cut watched for pacing and sync.
- Rebuilds with black-edged micro-transitions instead of the dissolves.
- Times each transition against the speech rather than evenly.
- Renders the master with no face-ghosting and phrase-accurate captions.
- Checks the master again after the transition and caption fixes.
- Runs a final transition check on the uploaded file.
Step ten is the substitution that works. A very short transition that passes through black never has both frames on screen together, so it smooths the join the way a dissolve does without ever showing you two of the same head.
Step two earns its keep before any transition is chosen. Looking at the selected frames together shows whether the presenter's position, clothing and framing actually match across the planned joins, and two shots that differ noticeably will draw attention to a transition however it is built.
Step eleven is what stops it feeling mechanical. A transition placed at an even interval will sometimes land in the middle of a word; placing each one against the speech means the join happens where a listener was already pausing.
What does the result look like?
An edit that still moves smoothly between the excerpts, with exactly one of you on screen at every moment of it, and joins that Vizard Agent placed between phrases rather than across the middle of them, so nothing lands mid-word.
Nobody notices the transitions, which is the entire job of a transition.
When does this not work well?
Some material genuinely needs the blend. A slow atmospheric piece, a montage cut between different scenes, or a cross-fade used deliberately as a stylistic device all rely on the two images overlapping each other, and having Vizard Agent remove that removes the effect itself.
- Deliberate cross-fades. The overlap is the point.
- Different scenes. Ghosting is not a problem there.
- Very fast cutting. There is no room for any transition.
- A moving camera on both sides. The join is harder to hide.
- Long dissolves. Anything long enough will show both frames.
How do you fix a result that came back wrong?
Say what you can see and roughly where in the cut it happens. Vizard Agent keeps the list of transitions it built and the speech timings behind them, so a fix changes one join rather than re-cutting the whole piece around it.
- "It feels choppy now." Longer black-edged transitions.
- "One join still ghosts." That transition replaced specifically.
- "It cuts mid-word." Re-timed against the speech.
- "Use hard cuts throughout." Rebuilt without transitions at all.
How does Vizard Agent compare to doing it yourself?
By hand a dissolve is the default smoothing tool and the ghosting is only visible while it plays, which is a fraction of a second in the middle of a transition. It is also judged in the timeline, where the preview may not render the blend the way the export does.
| By hand | Vizard Agent | |
|---|---|---|
| The transition | A dissolve | A brief transition through black |
| Two faces at once | Unavoidable | Never on screen together |
| Placement | Evenly, or by feel | Timed against the speech |
| Where it is judged | The timeline preview | The delivered file |
| Smoothness | Traded away | Kept |
Common questions
Why do dissolves double the face? Because they show both frames at once, and both frames have your face in them.
Will hard cuts fix it? Yes, and Vizard Agent offers a smoother option than that.
What is a black-edged transition? A very brief pass through black, so the two shots never overlap.
Will it look abrupt? Not at that length. Vizard Agent tunes it and shows you.
Can it keep some dissolves? Yes. Vizard Agent keeps them between different scenes, where the overlap works.
Where should the joins fall? Between phrases. Vizard Agent times them against the speech.
Does this apply to b-roll? Less so. Vizard Agent finds the problem specific to the same face on both sides.
Can it check the exported file? Yes, and it should — Vizard Agent checks the uploaded copy.
Will the captions still line up? Yes. Vizard Agent re-times them to the rebuilt cut.
Does the runtime change? Barely. Vizard Agent uses transitions shorter than the dissolves.
Can I see before and after? Yes. Ask Vizard Agent for frames at the same joins.
What about a whip or a blur transition? Both work; Vizard Agent will build either.
Does this happen with two cameras too? Yes, whenever the same person is on both sides of the blend.
Why not just make the dissolve shorter? Because any dissolve at all shows both frames, and a short one just shows them for less time.
