Length and format
How long the video runs and how the script is written.
Length
Seven lengths: 1, 3, 5, 8, 15, 25 and 45 minutes. The default is 5, or whatever your brand profile sets.
If your prompt names a length, the chip follows it. Write "a 4-minute explainer" and Vidax sets the nearest length it offers and tells you it did.
The finished video lands close to the length you ordered, not exactly on it — the script is written to a word budget and then fitted, so expect a range rather than a stopwatch match.
On a free balance
Format
Format is how the script is written, separate from how the video looks.
| Format | Voice |
|---|---|
| Auto | Picks the format from your topic |
| News report | Dated, attributed, wire-service voice |
| Documentary | Cold open, measured narration |
| Explainer | Fast, direct, answers a question |
| Story | Character-driven narrative |
| Top-10 / countdown | Ranked items, each with a payoff |
| Commentary | An opinionated take with a thesis |
Auto reads your own words. Say "a news style video on…" and it picks News report. Say "top 10…" and it picks the countdown.
Format also decides whether the run reads today's coverage. A current event does; a settled historical subject works from the record instead.
