How to find the words your captions left out
Ask Vizard Agent to audit the finished caption track against every word in the transcript. Words spoken right where a pause was cut out are the ones that disappear, because the caption sat on the boundary that was removed. It restores those phrases, checks they do not overlap their neighbours, and regroups them so they read as natural units.
What do you type into Vizard Agent?
Describe it to Vizard Agent as words going missing rather than as a timing problem. A gap in the captions and a caption that arrives late look almost identical on playback, and it will go looking for a timing fault if timing is what you name. One timestamp is enough to start from.
Prompt
What does Vizard Agent actually do?
The root cause is usually not a transcription failure. When pauses are cut from the picture, the caption timings have to be remapped onto the shortened timeline, and events sitting exactly on a removed boundary are the ones that mapping gets wrong. The words were transcribed correctly, then lost. In the session behind this article it:
- Inspected the two silent windows reported on a talking-head render and traced the caption events around them.
- Checked the source caption entries by their spoken text and examined the pause-mapping logic that rebuilt the timings.
- Found captions that began exactly on a removed boundary, restored those events, re-rendered and confirmed each caption now appeared immediately after the cut.
- Audited every caption event against every transcribed word and added the remaining missing words.
- Checked the restored words for overlap and readability, and regrouped them into natural phrases so none flashed up alone.
When does this not work well?
An audit compares captions against a transcript, so anything the transcript got wrong stays wrong. Vizard Agent can't restore words that were never transcribed, and heavily accented or overlapping speech is exactly where that happens. Translated captions won't match word for word, and some stylised caption tracks drop words by design.
Common questions
Why do captions disappear at cuts? Because events on a removed boundary get lost when timings are remapped.
Is it a transcription failure? Usually not. Vizard Agent checks the transcript before blaming it.
Can it show me what it added? Yes. Vizard Agent lists each restored word with its timing and spoken text.
