To make video ad variations, lock one master edit and change one part at a time. Pick the hook, the length, the caption style or the end card, and export each version as its own file.

## Steps

1. Finish a master edit you are happy with. Save it and do not touch it again.
2. Pick one thing to change. Use the table below.
3. Save a copy of the project. Change only that part in the copy.
4. Export the copy and name it so you can read results later.
5. Repeat from the master, not from the last copy. Otherwise changes pile up.
6. Upload the files as separate ads and track them in a [creative testing tracker](/templates/creative-testing-tracker-template).

We make Marxx. In [Marxx's AI video editor](/features/ai-video-editor) the built-in assistant can fit a cut to a target duration or reframe it for another placement. Marxx chat is on Match, $29 a month at launch prices (checked 3 Nov 2026).

## What to change

| Change | Example | What it can move |
|---|---|---|
| Hook | Open on the problem, then on the price | Hook rate, the share who watch past second three |
| Length | A 30-second and a 15-second cut | Hold rate and cost per result |
| Caption style | Bold box captions, then plain white text | How long people keep watching |
| End card | "Order today", then "See the range" | Click-through rate |

See how to [edit the first three seconds](/guides/how-to-edit-a-video-ad-hook) and how to [cut a 30-second ad into 15 and 6 seconds](/guides/how-to-cut-a-30-second-ad-into-15-and-6-seconds).

## Name your files

Use one pattern: product, hook, length, version.

```
desklamp_hookA_30s_v1.mp4
desklamp_hookB_30s_v1.mp4
desklamp_hookA_15s_v1.mp4
```

## A worked example

Say you want to test 3 hooks and 2 lengths of the same ad.

- 3 hooks x 2 lengths = 6 files
- Add 2 caption styles: 6 x 2 = 12 files

Every file needs enough budget to read a result. So test the hook first with 3 files. Then take the winning hook and test lengths. See [how to build a creative testing budget](/guides/how-to-build-a-creative-testing-budget).

## Mistakes to avoid

- Changing the hook and the length in the same copy
- Editing the last copy instead of the master, so changes pile up
- Giving files names like "final2", which tell you nothing in a report
- Judging a result before the ad has enough views to compare

## FAQ

### How many variations should I make?

Start with 3 hooks on the same master. Add a second change only after you have read the first result.

### Why change only one thing?

If you change the hook and the length together, you cannot tell which one moved the result.

### Do variations help with ad fatigue?

A new opening gives a tired ad a fresh start. See [how to fix ad fatigue](/guides/how-to-fix-ad-fatigue).
