# AI Facebook video ad maker built for Reels and feed.

An AI Facebook video ad maker makes video and image ads for Facebook and Instagram without a shoot. RiffAds turns your script into a lip-synced AI actor video, re-frames it for Reels or feed with its Resize tool, and prices every job before it runs.

## What is a Facebook video ad maker?

A Facebook video ad maker is software that drafts, voices and renders video ads for Facebook and Instagram. Give it a script or a product photo, and it returns an AI actor speaking your lines or a static image ad. RiffAds shows the cost of each job first, and you upload the finished file in Meta Ads Manager yourself.

### How it works

1. **Choose the format**: Pick a talking actor for a Reels video, or an image model such as Nano Banana Pro for a static ad.
2. **Brief the script**: Paste your own script, or give the AI writer your product and audience and let it draft a few hooks to test.
3. **Check the credits**: Each job shows its credit cost before it renders, so you decide how many variants to make before you spend.
4. **Resize and upload**: Resize a copy to 4:5 or 1:1 if a placement needs it, add captions, then upload the files in Meta Ads Manager yourself.

## Questions

### What size should a Facebook or Instagram Reels ad be?

Vertical 9:16. For Instagram Reels ads, Meta's Ads Guide lists 1440 x 2560 pixels and files up to 4GB, and suggests keeping at least 14% at the top, 35% at the bottom and 6% on each side free of text and logos. RiffAds makes talking actor videos in 9:16, 16:9 or 1:1, and its Resize tool turns a finished video into 4:5 with bars or a crop.

### How long can an Instagram Reels ad be?

Meta's Ads Guide lists 0 seconds to 15 minutes for Instagram Reels ads. One RiffAds talking actor clip is shorter: under 60 seconds of audio on OmniHuman 1.5, 4 to 30 seconds on Seedance 2.5 Actor, or 5 to under 14.8 seconds on MiniMax H3 Max Lip Sync. Input longer than the model allows is refused before any credits are held, not cut short, and the Stitch Videos tool joins clips into a longer ad.

### Does Meta add an AI info label to ads?

Yes, in some cases. Since June 1, 2026, Meta detects ad media made with third-party AI tools, using signals such as C2PA metadata, and adds an "AI info" label under "About this ad". In the European region, California, New York, India and Taiwan you can also self-disclose it. Social issue, election and political ads must disclose a photorealistic AI person, even one who does not exist, or they are rejected.

### Can I run AI UGC videos as Facebook and Instagram ads?

Yes, as long as the ad does not mislead. FTC staff say the testimonials rule has no blanket ban on AI avatars in marketing. What it targets is a fake or false testimonial, such as an AI actor claiming to be a buyer, and an avatar ad can still be deceptive under the FTC Act. Let the actor present your product, then upload the file in Meta Ads Manager yourself.

### Can AI write Facebook ad copy and make image ads too?

Yes. In RiffAds the AI writer drafts text from a short brief, such as hooks, a video script or the primary text for your ad. Image models such as Nano Banana Pro, GPT Image 2.5 and Seedream 5 make static ads, and the Rebuild an ad around your product workflow reads an ad you like and returns two static versions with your product in them.

### How much does it cost to make a Facebook video ad with AI?

About 848 credits on RiffAds for a 30 second talking actor video with its voice-over, and 1 credit is $0.01. The studio shows the cost before you generate. Plans start at $49 a month, or try Growth for $1 for 3 days with 500 credits, then $99 a month. Credits never expire.

### Can my AI agent make Facebook and Instagram ads?

Yes. The API, MCP, Agent Skills and CLI come with every plan, so an agent such as Claude can write hook variants, price each ad and render it from the same credits as the studio. An owner or admin sets the caps: 600 credits per job and 2,000 a day by default, plus an optional budget on each API key. The agent gets a download link, not access to your Meta account.
