TL;DR — Keep each individual message to 30-60 seconds regardless of headcount. The total reel length should scale with contributor count, but past about twenty contributors, group or trim clips rather than letting the full reel run past four or five minutes.
- Per-person: 30-60 seconds, not longer.
- Total reel: 2-3 minutes for small teams, up to 5 for larger ones.
- Past twenty contributors, trim or group rather than including everything in full.

The short answer
Thirty to sixty seconds per contributor, and a total reel length of two to five minutes depending on headcount. Below ten contributors, use every message close to full length. Above twenty, start trimming to the strongest ten to fifteen seconds of each clip so the whole reel doesn't run past five minutes.
Why shorter clips actually say more
A message with a time limit in mind tends to get straight to the specific thing worth saying, rather than warming up for thirty seconds first. Encourage brevity in the prompt itself rather than leaving duration open-ended.
A length guide by team size
| Contributors | Per-clip length | Target total reel |
|---|---|---|
| Up to 10 | 45-60 seconds | 2-3 minutes |
| 10-20 | 30-45 seconds | 3-4 minutes |
| 20+ | 15-30 seconds, trimmed | 4-5 minutes |
Frequently asked questions
Is a longer video always better?
No — attention drops off past about five minutes regardless of how many people contributed, so trimming matters more than including everyone in full.
Should we cut anyone out entirely to save time?
Prefer trimming everyone down over cutting any one person out completely — being left out entirely reads worse than a short clip.
Does video length affect how it's shared afterwards?
A shorter reel is more likely to actually get rewatched later, which is usually the point.
