How to get ten versions of the same video to choose between
Tell Vizard Agent you want one video in ten treatments, not ten videos. It builds the shared parts once (the narration, the subtitle timings, the cut), then varies only the axes you name, renders the set in parallel, and puts frames from all ten on a single contact sheet so you can compare them without watching ten files.
What do you type into Vizard Agent?
Say "the same video". Those three words do most of the work, because the default reading of "ten videos" is ten separate pieces of work rather than one piece of work in ten coats of paint, and Vizard Agent will do the expensive thing if that's what you appear to ask for. Name the axes that may vary.
Prompt
What does Vizard Agent actually do?
Almost all of the work happens once, before any individual variant exists, which is what makes a set of ten cost barely more than a set of two. One narration recorded once means the only audible difference between two variants is the thing you asked to vary, not a take that happened to land better. In the session behind this article it:
- Found the meaningful scene boundaries in a gameplay source and auditioned voices: an energetic one, a low one and a playful one.
- Generated each line of the narration and three music beds in different moods.
- Assembled one shared speech track for all ten variants, took exact subtitle timings from it and built one subtitle treatment used by every version.
- Measured the level of each music bed before the batch mix, since beds at different loudnesses bias the choice toward the loud one.
- Rendered all ten variants in parallel, then built one contact sheet of all ten and collected the download links.
When does this not work well?
A variant set is for choosing between treatments, not for finding out whether the edit works. If the cut itself is wrong, all ten will be, and the sheet shows ten versions of the same problem. Too many axes at once makes nothing attributable, and beyond about a dozen you'll stop looking properly.
Common questions
Does it cost ten times as much? No. Most of the work is shared, and Vizard Agent only repeats the render.
Can I vary just one thing? Yes, and that gives the cleanest comparison. Tell Vizard Agent which one.
Should the music be the same loudness? Yes, or you're testing loudness. Vizard Agent measures the beds first.
