In brief:
- What you give it: the product, the one benefit, the hook and the call to action.
- What you get: a short, captioned ad that works on mute, built for 9:16 and renderable in 1:1 and 16:9 too.
- Testing hooks: each new opening is a 5-credit edit to the same video, not a new one.
- Cost: 35 credits to create and 10 per render; three hooks and one render come to about 55 credits.
What is an AI video ad maker?
An AI video ad maker builds a short video ad from a written brief: it writes the on-screen text, designs and animates the scenes, adds captions and music, and outputs the sizes each ad platform needs. Instead of editing footage, you describe the ad and adjust the draft by asking for changes.
How do you make a video ad with Relo?
- Write a short brief: the product, the one benefit, the hook, the call to action, and "15 seconds, vertical".
- Switch on captions and music in Video options. Both are free. Energetic or Upbeat music suits most ads.
- Watch the draft and ask for changes: "Make the hook text bigger", "End on the app store badges".
- Make hook variants by asking for a new opening. Each one is a 5-credit edit.
- Render 9:16 for TikTok, Reels and Shorts, and 1:1 or 16:9 for feed and YouTube ads, 10 credits each.
An example brief:
15-second vertical ad for Penny, a budgeting app. Hook: "Where did my $400 go?" on a fast zoom. Show spending sorting itself into categories. End on "Free on iOS and Android". Energetic, bold captions, upbeat music.
What structure works for a 15-second ad?
| Seconds | Beat | What goes on screen |
|---|---|---|
| 0–2 | Hook | A question the viewer is already asking, or a bold claim |
| 2–9 | Benefit | The one thing the product does for them |
| 9–13 | Proof or product | The product on screen, or a number that backs the claim |
| 13–15 | Call to action | What to do next, with your logo |
The vertical video ad guide covers hooks, safe zones for text and when to add a voiceover.
Which sizes do ad platforms need?
| Placement | Size |
|---|---|
| TikTok, Instagram Reels, YouTube Shorts | 9:16, 1080×1920 |
| Instagram and Facebook feed | 1:1 |
| YouTube and LinkedIn | 16:9 |
In Relo you render each size from the same video, so a campaign doesn't mean rebuilding the ad three times.

| Item | Credits |

Can I copy the style of an ad that works?
Yes. Paste a link to a reference video (+10 credits) and Relo follows its pacing, structure and look with your content. Use Clone it to copy its script beats and timing too, then make variants from it.

Frequently asked questions
What size should a TikTok or Reels ad be?
9:16 vertical at 1080×1920. Keep key text in the middle of the frame, clear of the app’s buttons at the bottom and right edge.
How do I test different hooks?
Make the ad once, then ask for a new opening by chat. Each variant is a 5-credit edit, so three hooks cost 10 credits more than one.
Do ads need captions?
Yes. Many people watch with the sound off. Captions in Relo are free.
How much does a video ad cost?
35 credits to create it and 10 per render. Three hook variants and one final render come to about 55 credits.
Can I match the style of an ad I like?
