How to compress a long product review into one short
Upload the long review and ask Vizard Agent for one short. Vizard Agent looks at a frame from every minute to map the whole video, checks each on-screen figure and product graphic individually, cuts the sections that carry the verdict, and joins them with quick transitions rather than hard cuts.
What do you type into Vizard Agent?
State the constraints as a list and say you want one short, because the default from a long video is several clips. Vizard Agent treats a maximum duration, a required aspect and a "must contain the key parts" instruction as three requirements to satisfy together, a more reliable brief than a description of the feel.
Prompt
What does Vizard Agent actually do?
A review's value is in its numbers, so a compressed review keeps the measurements and the verdict rather than the most watchable moments. A cut that lands halfway through a measurement graphic delivers half a fact, which is worse than leaving it out. In the session behind this article it:
- Transcribed the audio and mapped the shots, then looked at a frame at every minute mark, one through seventeen, rather than sampling every few minutes.
- Inspected the word-by-word timestamps, extracted frames at the possible cut points and reviewed them as a grid against the transcript timings.
- Simulated the vertical crop on the key frames and checked the framing at each moment.
- Checked each on-screen product graphic individually: every measurement, every comparison card, every title.
- Extracted the nine vertical clips in parallel, built a closing card, aligned the subtitles to the new timeline and delivered a 119.04-second short at 1080x1920, with the total verified under the two-minute ceiling before rendering.
When does this not work well?
A compressed review is shorter than the thing it summarises, so someone has decided what a viewer doesn't need. Nuance gets cut first, and a qualified verdict compresses into an unqualified one. Wide review footage crops hard, graphics sized for wide may not read after reframing, and a sponsored disclosure has to survive too.
Common questions
One short or several clips? Say which. Vizard Agent defaults to several from a long video, so ask explicitly for one.
Will the measurements survive? Yes, if you say they matter. Vizard Agent checks each on-screen figure individually.
Why look at every single minute? Because a review has no obvious structure to skim, and sampling every few minutes misses whole product sections.
