How to add an on-screen correction when the speaker said the wrong thing
Give Vizard Agent the correction as the exact line you want on screen. It leaves the spoken audio untouched, places the note above the captions for the seconds the mistake is audible, and checks the finished frame to be sure it reads clearly and does not land on top of the captions or a name title.
What is the short version?
A speaker names the wrong thing in an otherwise good take. Re-recording is not available, cutting the line loses the sentence around it, and letting it stand publishes a mistake — so you annotate it, the way a broadcaster would.
- Go to Vizard Agent with the moment and the wording.
- Say the note goes above the captions, not inside them.
- Ask it to show you the frame.
What do you need before you start?
The moment and the exact words. Vizard Agent will not invent the correction — you decide what it should say, and the phrasing matters more than it looks, because a note that is longer than a glance is a note nobody reads.
- When the mistake happens. Roughly is enough.
- The exact correction line. Short, in your words.
- Whether the captions stay verbatim. Usually they should.
- What else is on screen there. Name titles, lower thirds.
- How prominent it should be. Discreet, or unmissable.
What do you type into Vizard Agent?
Give the line and the placement in one instruction. Left open, a correction can be applied three different ways — edited into the captions, spoken over, or annotated — and only one of them keeps the record honest.
Prompt
Variants worth knowing:
- "Do not change the audio or the captions." Keeps the record.
- "Above the captions." The placement that reads as a note.
- "Reading exactly." Your wording, not a paraphrase.
What does Vizard Agent actually do?
Here is the sequence Vizard Agent worked through on a real film cut from staff interviews, where the correction was one of several caption fixes made in the same pass. Notice carefully which things it changes and which ones it deliberately leaves exactly as they were.
- Finds the moment in the word-level transcript.
- Corrects transcript spellings where the captions were wrong.
- Leaves the spoken words alone where the speaker misspoke.
- Prepares the correction line as its own element.
- Places it above the caption band.
- Times it to the seconds the mistake is audible.
- Renders and checks the note on the frame.
- Confirms it does not collide with titles or captions.
- Checks it is legible at the size the video plays at.
Step three is the distinction the whole job rests on. A caption that mishears a word is an error in your transcription and should be fixed silently; a speaker saying the wrong thing is a fact about the recording, and changing the caption to disagree with the audio is worse than leaving it.
Step six matters for how it reads. A note that appears with the mistake and leaves with it is clearly attached to that sentence, whereas one that hangs around afterwards starts to look like a general disclaimer.
Step eight is not optional in a video that already has captions and name titles. The area above the caption band is the busiest part of the lower frame, and a correction placed there without checking usually lands on something.
What does the result look like?
The take exactly as recorded, with a short line on screen for a few seconds saying what the right answer actually is. Viewers read a note like that as care rather than as an error, which is the whole difference between annotating a mistake and quietly hiding one.
Vizard Agent also tells you the exact seconds it is on screen, so you can hold it longer when the wording needs more reading time than you expected.
When does this not work well?
An annotation suits a small factual slip and nothing larger. Vizard Agent cannot rescue a line that is wrong in substance with a note, and a video that needs several corrections is usually telling you the take should be recorded again rather than annotated.
- Substantive errors. A note cannot carry those.
- Several corrections. It starts to look unreliable.
- Fast cuts. There is no time to read.
- Videos with no captions. A floating note looks odd.
- Formal or regulated content. Ask what the rules require.
How do you fix a result that came back wrong?
Say whether the problem is the wording, the timing or the placement. Because Vizard Agent built the note as its own separate element rather than as part of the captions, each of those is an independent adjustment, and naming the right one avoids redoing all three.
- "It is gone before I can read it." Held longer.
- "It sits on the captions." Moved up, or the captions down.
- "Reword it." Your wording, applied exactly.
- "Make it less prominent." Smaller, or a plainer style.
How does Vizard Agent compare to doing it yourself?
By hand the choice is usually between cutting the line and living with it, because adding an annotation means building a graphic, timing it and checking it against everything else in the lower third. Most people live with it.
| By hand | Vizard Agent | |
|---|---|---|
| The options | Cut it, or leave it | Annotate it |
| The captions | Sometimes quietly altered | Left verbatim |
| Timing | Approximate | To the seconds it is audible |
| Collisions | Found on playback | Checked on the frame |
| The wording | Improvised | Exactly what you wrote |
Common questions
Should I change the captions instead? No. Vizard Agent keeps captions matching what was said.
Can it fix the audio? Vizard Agent can replace words, but a note is more honest and far cheaper.
How long should it stay up? Long enough to read. Vizard Agent reports the duration.
Where exactly does it go? Vizard Agent puts it above the caption band unless you want it elsewhere.
Will it collide with a name title? Vizard Agent checks the frame for exactly that.
Can I have several? Yes, though Vizard Agent will note when there are too many.
Does it change the transcript file? No. Vizard Agent leaves the spoken record exactly as it was recorded.
Can it match my caption style? Yes, or be deliberately different so it reads as a note.
What about a spelling error in the captions? That is a different fix; Vizard Agent corrects those directly.
Will it re-render everything? Vizard Agent re-renders only the section carrying the note.
Can it be a symbol rather than a line? Yes, though Vizard Agent will point out that plain wording is clearer.
Does it work in other languages? Yes. Give Vizard Agent the wording in the language on screen.
What if I am not sure of the right answer? Then do not annotate. Vizard Agent uses your wording, not its own.
Why not just cut the sentence? Because you usually lose the thought it was part of.
