<b>I cut the Short to 18 seconds and it did worse</b>

Conventional wisdom says shorter wins. So I took a 38-second Short that ran at 22% completion and trimmed it to 18 seconds, expecting completion to soar.

It dropped to 16%, and total watch time per view fell by 6 seconds.

Here's the thing — the cuts I made removed the two micro-loops in the middle that kept people curious. I'd optimized for length and accidentally deleted the retention engine.

The fix wasn't longer or shorter. I rebuilt the 18-second version to 31 seconds, but spaced three open loops at seconds 4, 13, and 22.

The result: completion rose to 34% and watch time per view beat the original 38-second cut.

The lesson: length isn't the lever — loop density is. A longer video with questions you keep almost answering beats a short one with nothing pulling. Don't cut seconds; cut dead air between hooks.
