How to cut footage to a narration and keep every shot short
Give Vizard Agent the narration and the footage, and state the maximum shot length as a rule rather than a preference. It transcribes the narration into timed sections, indexes what the footage actually shows, and pins each spoken beat to a span, so the picture follows the words instead of running alongside them.
What do you type into Vizard Agent?
State the rule in absolute terms. "Keep it snappy" produces a cut with a few long shots in it; "no shot longer than four seconds, split longer scenes into several cuts" produces a cut you can check against a number. Vizard Agent also needs footage with enough coverage, because no edit map illustrates lines the source never shows.
Prompt
What does Vizard Agent actually do?
Every dissolve in a finished source is a run of frames that are half one shot and half another, or simply white, and a cut that lands there looks like a mistake in your video. Without an index of what the source shows and when, matching picture to narration reduces to cutting on the beat and hoping. In the session behind this article it:
- Transcribed the narration and surveyed one long source film in parallel, read both into one compact edit map and grouped the narration into timed story chapters.
- Built a scene index of the source, pinned the key beats to precise source spans and rendered the synced cut under the four-second rule, chapter by chapter.
- Inspected a chunk-render failure, corrected the join list, found missing duration and repaired overlapping source windows.
- Discovered the cut was using the source's own fade frames as picture, removed the white and black transition ranges from the edit map and re-rendered every chapter that had used them.
- Extended a chapter the removal had left short with a valid held frame, trimmed a stray narration tail and built an ending that does not cut the voice off.
When does this not work well?
Some narration cannot be matched from the footage you have. If the voice track describes things the source never shows, Vizard Agent has the choice of repeating shots or showing something irrelevant, and it tells you which sections have no coverage rather than quietly padding them. Narration with long pauses also produces cuts over silence.
Common questions
What maximum length should I choose? Three to five seconds suits fast-paced work. Vizard Agent will hold to whatever you set.
Why do white flashes appear? They are the source's own dissolves. Vizard Agent strips those ranges out.
How do I check the length rule was kept? Ask Vizard Agent for the cut list: every shot and its duration.
