# Stack two clips to prove the link

A fitness format, measured November 8, 2026 by Volume. https://tryvolume.app/working/fitness/stack-two-clips-to-prove-the-link

Use a top-and-bottom split screen to compare two versions or movements in sync. It worked for 3 accounts, with a median of 22x their usual reach. Type: Editing trick. Seen as: Video, Voiceover.

## Why it works

The viewer sees the match or difference at once, with no explanation needed. Corner highlights or a talking head add the commentary.

## How to make it

1. Film both movements from the same angle
2. Stack or sync them in a split screen
3. Add color highlights or a short commentary on what matches

## Hook formula

[Easy exercise] vs [hard skill]: same [joint path]

## How this is measured

- Every post is compared with its own account's usual reach, not with other accounts. "14x their usual" means the post got 14 times the median views of that account's recent posts.
- TikTok videos and Instagram Reels are measured on views. Instagram carousels have no view count, so they are measured on likes against the account's usual likes, and say so.
- A post makes the library at 2x its account's usual or more. A format is a repeatable move (what is said or shown, or how it is edited) that several accounts used in breakout posts. It is listed here once it worked for 3 or more different accounts.
- Formats rank on how many accounts they worked for and how far above usual, damped so a fluke on one tiny account cannot outrank a format that worked for ten.
