Keep the decisions that need your judgment, and hand the repetitive cuts to the model. You choose the claim, the footage, and whether the result is true. The model can find moments, draft the on-screen line, and export a vertical file. You watch that file on mute and reject anything that could have been said by a competitor.

AI is useful on a marketing reel when it saves the cutting and the first draft of the line. It is a waste when it invents a product you do not sell, or when you post the file without watching it.

## What people mean by a marketing reel

A marketing reel shows the product doing a job a buyer cares about, in under a minute, with the point written on the screen. It is not a trend with your logo in the corner, and it is not a brand anthem. The buyer should be able to say what you do after one viewing.

The raw material is almost always something you already recorded for another reason: a demo, a webinar answer, a loom you sent a customer, a conference clip. AI does not remove the need for that footage. It removes the evening you would have spent finding the twelve seconds inside it.

## Which steps you should still do

You still decide the claim. A model will happily make a reel about a feature you do not want to lead with, because that feature was mentioned out loud. Write the claim down before you upload anything. 'Show that setup takes one afternoon, not a quarter' is a brief. 'Make it viral' is not.

You still check that the line is true, that the customer's face or data is allowed to be public, and that the product on screen is the product you sell today. Those are not editing tasks. They are publishing tasks. No model should take them from you.

1. **Name the claim.** One sentence a buyer could repeat. If you cannot say it, do not ask a model to find it in the footage.

2. **Choose the source.** The demo, the webinar, or the screen recording that actually shows the claim. Do not upload a montage and hope.

3. **Review on mute.** Watch the file with sound off. If the claim is not on screen, send it back or recut it.

4. **Post, or do not.** Download the file. Put it on the account yourself, or drop it. Publishing is the part you keep.

## Which steps a model can do

A model is good at scanning a long take for moments where the topic changes, drafting a short line from words you already use, and framing a vertical crop so the speaker stays in shot. That is the tedious middle of the job. It is also the part founders skip, which is why the footage sits on a hard drive.

A model is bad at knowing which claim matters this week, at sensing that a joke will age badly, and at noticing that the price on screen is the old price. Treat the output as a first cut from a junior editor who has read your site and has never met your customer.

Split the job before you pick a tool. If a product wants to own the right-hand column, do not use it.

| Step | You | A model |
| --- | --- | --- |
| The claim | You write it | It should not invent a new one |
| The footage | You filmed it | It should not replace it with stock |
| Finding moments | You can, slowly | This is the useful part |
| First draft of the line | You can | Fine, if it uses your words |
| Truth and permission | You | Never hand this off |
| Publishing | You | A tool that auto-posts is a different product |

## How to review a cut before it goes out

Watch once on mute and once with sound. On mute, read only the on-screen line. On sound, check that the line does not contradict what was said. A common failure is a punchy caption over a sentence that was hedged. The caption says 'we replaced the CRM.' The speaker said 'we are trying to replace the spreadsheet.' That reel should not go out.

Then ask three questions. Could a competitor paste their logo on this and post it unchanged? Is there a number, a screen, or a specific objection, or only adjectives? Would I say this line on a sales call? If the first answer is yes, or the second is no, or the third is no, rewrite the line or drop the clip.

```
Review note, pasted onto the file before you post

Claim I asked for: setup is one afternoon.
On-screen line: "Most teams are live the same day."
What was actually said: "Our last three customers were live the same day. Yours depends on the import."
Decision: rewrite the line to "Our last three customers were live the same day." Do not post the absolute version.
```

## What to skip in an AI reel tool

Skip a tool whose demo is stock footage of people who do not work at the company. You will spend the week explaining that the face is not yours. Skip a tool that posts to your accounts the moment the render ends. You want a file. Skip a tool that will only write a generic subtitle of every word, with no sense of which sentence is the offer.

Also skip the workflow where you re-explain the entire product in a blank prompt every time. If the tool cannot read the site and the posts you already published, you are the one doing the voice work, and the model is only a caption style.

## Where Runmeg fits

ReelGen takes a video you upload, picks moments, and writes the line from the product voice it already has. You download the files and post the ones that survive the review above. It does not publish them, and it does not invent a presenter. If you wanted a hand-built timeline, this is the wrong tool. CapCut, or any editor you already know, is the right one for that.

## Questions

### Can AI make a marketing reel with no footage?

Some products will generate a face and a script. That is a different job, and it often looks like an ad for the tool rather than for you. For a product, start from a video you already recorded.

### How many reels should I make from one video?

As many as have a distinct claim. Five is a reasonable batch to review in one sitting. Posting all five on the same day is usually worse than posting the two that survived the mute test.

### Should I edit the AI line?

Yes, whenever it is broader than what was said, or whenever you would not say it on a call. The draft is there to save the blank page, not to be the last word.

### Does the AI need my brand colors?

Colors help recognition. They do not fix a vague line. Get the sentence right first. A red wordmark on a generic sentence is still a generic reel.
