Meta ad creative generator
Genyad generates Meta video ad creative from your footage and exports it at 9:16 for Reels and 4:5 for feed with each placement's safe zone respected. For Advantage+ campaigns the number that matters is distinct creatives, not files: 8 to 20 genuinely different ads give the system something to optimise across.

How to do it in Genyad
- Upload footage and let it index.
- Create a campaign with the offer, audience and language, and set duration to 15 seconds or under for feed placements.
- Generate 8 to 20 variations covering at least three different arguments.
- Export 9:16 for Reels and Stories and 4:5 for feed. Each export is laid out for its own safe zone.
- Upload the whole set to one ad set rather than drip-feeding it, and let Meta allocate.
What good looks like
| Placement | Aspect | Length that performs | Watch out for |
|---|---|---|---|
| Reels | 9:16 | 6 to 20s | Top 14% and bottom 20% covered by UI |
| Stories | 9:16 | 6 to 15s | Same safe zone, faster drop-off |
| Feed | 4:5 | 6 to 20s | Headline area competes with your overlay |
| Marketplace and right column | 1:1 | 6 to 15s | Often muted, captions carry it |
- The hook earns the next two seconds. If the first frame is a logo, the ad is already lost.
- Captions are not optional. A large share of feed impressions are muted.
- One argument per ad. Two arguments in 15 seconds means neither lands.
Mistakes that cost you the test
- Treating four aspect ratios as four creatives. That is one creative in four shapes. Advantage+ needs different ads.
- Reusing last quarter's winner unchanged. Decay is measurable and predictable, see the fatigue report.
- Letting the offer land in the last two seconds. Most viewers never reach them.
- Ignoring the 4:5 headline area. Your overlay ends up behind Meta's own text.
Frequently asked questions
What is the best video ad format for Meta in 2026?
9:16 at 1080x1920 for Reels and Stories, 4:5 at 1080x1350 for feed, both under about 20 seconds, with burned-in captions and the offer stated before the halfway point.
How many creatives does Advantage+ need?
Enough genuinely different ads to choose between, practically 8 to 20 live per active campaign. One ad exported in four ratios counts as one.
Does Genyad upload directly to Ads Manager?
No. It exports standard MP4 files ready to upload to Ads Manager or TikTok Ads Manager.
Are exports watermarked on the free plan?
No. The free plan's five variations export without a watermark, which is the point of having a free plan you can judge the output on.
