How to make a short that must not exceed a hard time limit
Give Vizard Agent your script and a hard time limit. Vizard Agent auditions narrators, records the full read, measures it against your ceiling, and when it runs long it speeds the narration slightly and rescales every word timing so the graphics still land on the lines they belong to.
What do you type into Vizard Agent?
Write the constraint as a rule, in capitals if you like. Vizard Agent holds a stated hard limit and will change the read rather than your script to meet it, which is exactly the behaviour you want when the words are the part you actually care about. Say explicitly if no introduction or outro should be added to fill time.
Prompt
What does Vizard Agent actually do?
Platform limits are absolute: fifty-nine seconds means fifty-nine seconds. When the narration came back too long, Vizard Agent changed the delivery rather than cutting the words. Speeding a read invalidates every timing you had, so it re-derived the whole word map at the new speed before building the graphics. In the session behind this article it:
- Extracted frames from the previous video in the series and studied eight of them in detail.
- Searched for a mature documentary narrator, generated a short test line, then sampled three stronger voices and two subtle music beds, measuring each before choosing.
- Generated the full narration, timed the read and took a word-level transcript.
- Sped the narration by ten per cent to fit inside the 59-second ceiling.
- Printed every word with its rescaled timestamp, then rendered the opening and the motion cards against those numbers.
- Measured the delivered file rather than assuming: 58.0 seconds at 1080x1920, inside the ceiling and inside the target range.
When does this not work well?
Something always gives to meet a hard limit, so decide in advance whether you would rather lose words or pace. A ten per cent speed-up is slightly audible to a careful ear, and beyond that it sounds rushed. If the words need seventy seconds, they need cutting rather than speeding. And a diagram held on screen for one second is decoration, not information.
Common questions
Will it cut my script to fit? Only if you ask. By default Vizard Agent adjusts the delivery and leaves your words intact.
How much can it speed the read? Around ten per cent is unobtrusive. Beyond that, cutting lines is the better answer.
Will the graphics still line up? Yes. Vizard Agent rescales every word timing after the speed change and builds the cards against the new numbers.
