Two ways to change what’s in a trailer after it’s been generated. Pick based on how much you’re changing.

​
Rebuild with different clips

Best when the AI’s selection is mostly right but you want to swap one or two moments.
1

Click Rebuild with different clips

Action button under the video on the trailer review page.
2

Toggle moments

The modal shows every detected moment as a checkbox, both the ones the AI included and ones it considered but rejected. Toggle them on or off.
3

Submit

The trailer recomposes in 1–3 minutes. You’ll see a progress panel where the player was.
4

Done

The new trailer replaces the old one at the same URL, any share link you’ve already sent updates automatically.
Rebuild is non-destructive on the video file, you’re just swapping which moments get composed. The original transcript, deal brief, and engagement data stay attached.

​
Build your own trailer (custom clips)

Best when you want a fully bespoke cut, different intro, different feature emphasis, A/B test variant.
1

Click Build your own trailer

Action button under the video.
2

Pick exact start/end timestamps

The modal lets you scrub the source recording and add up to 12 clips with hand-picked in/out points.
3

Optional: add a custom narration prompt

“Open with the energy problem, then walk through the integration features, close on pricing.”, guides the AI in stitching narration between clips.
4

Submit

The AI composes them into a trailer with narration that ties them together. ~2-4 minutes.
5

Lands as a NEW demo

The custom trailer doesn’t replace the original, it’s a new demo row, so you can A/B test different cuts side-by-side.

​
When to use which

SituationUse
AI picked the wrong feature on slide 4Rebuild
Want to swap two moments and add a thirdRebuild
Original trailer is “discovery-heavy”, want a “feature-heavy” versionBuild your own
Doing an A/B test on cutsBuild your own (creates new demo, original stays intact)
Prospect’s CIO asked for a 30-second exec summaryBuild your own (cap at 4-5 short clips)

​
Editing narration text directly

Not yet supported. Today the path to changing narration is:
  1. Edit the moment’s feature/benefit text in your AI Personalization context, OR
  2. Use Build your own trailer with a custom narration prompt
Direct narration text editing is on the roadmap.

​
Re-running the AI summary / deal brief

Re-running the AI after a rebuild is automatic, the new trailer’s deal brief regenerates with the new moment set. No separate action needed.

​
Reverting a rebuild

There’s no explicit revert today. If you rebuilt and don’t like the result, you can:
  1. Rebuild again with the original moment selection
  2. Or contact support, we can restore from the previous trailer file if you reach out within a few days
