Making ads

Create multiple video ads to choose from with simple prompts
Use Captions to create video ads at scale. To get started, enter a link to the product or service you want to advertise. AI will scan your website and use that information to generate several scripts for you to choose from. Once you’ve selected a script, choose a digital avatar as your spokesperson. Customize the character’s background and outfit to suit your video’s tone. Then, choose your subtitle style and click “Generate Ads.”
Captions will generate multiple videos featuring real product images and your AI actor. Select your favorite ads for publication or additional editing, then share across platforms — it’s that easy.
Save time with fast ad generation and no post-production process
Captions lets you quickly create video ads that fit your brand’s voice. AI generates multiple variations of each ad, and they’re ready within minutes. These options take different visual approaches, and you can select your favorites. Once they’re ready to publish, it’s just as easy to create additional sets of ads. Take another approach to the same product, or target a different offering altogether. You’ll find yourself building huge campaigns in the time it would have taken to make a single ad using traditional methods.


Prepare your video for use on your desired platforms
Captions expands your video marketing efforts by letting you customize ads for different social media platforms. Adjust aspect ratios and frame rates to suit sites like YouTube, Facebook, and X (formerly Twitter), then share across your channels. No matter which adjustments you make, Captions’ video editor intelligently keeps the subject in the frame, even when the video changes from horizontal to vertical.
Since our ad maker generates videos quickly, you can tailor unique messages to your YouTube subscribers and LinkedIn followers with just a few clicks. Simply input this viewer base into the “Target Audience” box and watch as AI adjusts its messaging to each unique platform.
How to make video ads
in three steps

Paste your
product link
Upload a link to your product or service, and Captions will generate several script options. Select your favorite and edit it if necessary, or upload your own script.

Generate
your ads
Pick the AI Creator and select a background and font style that will engage your target audience. Tap “Generate,” and Captions will create your ads.

Share videos across platforms
Select your favorite ads to export and share. You can upload to social media as they are or make additional edits before posting.

Select the perfect avatar
- The AI Creator lets you choose from various characters to speak for your brand. These avatars can even interact with one another as narrators in your script. Select the digital actors that match best with your brand, modify their style if necessary, and put them to work in your video ads. AI avatars inform, engage, and persuade your viewers with natural-sounding speech and authentic facial expressions. You can reuse the same character in an entire ad campaign or mix it up to feature a range of avatars.
Become your own avatar
- With Captions, you can transform into a digital character using the AI Twin feature. Film yourself reading a short script and upload it to the site. Then, the AI will use that footage to generate future videos based on scripts you select — no more cameras, reshoots, or outtakes. Just select your own image as an AI Creator and cast your digital likeness.
Engage with music
- While editing your ad, include royalty-free, AI-generated music in your posts. Just tap “Music,” select your desired AI model, and enter a text prompt to describe the song you need. Captions will generate a new tune customized for your ad. You can edit the song as needed or try various options until you get the perfect one for your brand. Create studio-grade sound without expensive equipment or technical expertise.

Frequently asked questions
What type of video ads are most effective?
Different ads work best depending on the product or audience. For instance, makeup fans enjoy seeing people using products, so tutorials and user-generated reviews tend to perform well.
Examples of other popular posts include explainer videos, product spotlights, and customer testimonials. These ads feature demonstrations and feedback from real users, which creates credibility for your brand. Mix and match styles to find the right ones to make the best video for your brand.
What makes a good video ad?
Great marketing posts grab viewers’ attention in the first few seconds and have a clear call to action. To boost views and engagement, tailor ads to your audience, keep them short, and use royalty-free music. The best ads lead to a specific result, whether that’s selling a product, growing a mailing list, or encouraging channel subscriptions.
What type of video ads can I make with Captions?
You can use Captions’ AI ad maker to make any commercial you want. Use it to promote products or services, send viewers to your website, or share a cause you care about. Whether you need a single video or a large ad campaign, there’s no limitation on what you can make with Captions’ creative suite.
How long should video ads be?
Aim to keep social media ads under 15 seconds and in-stream ads under 10. Work to capture attention early with short-form video so viewers will want to stick around for your entire ad. Website pages can feature videos of any length, but 30 to 60-second clips are more likely to capture viewers’ attention. Use Captions’ video ad editor tools to trim posts to the right length.
What platforms can I use video ads on?
All the major social media platforms, including Facebook, Instagram, and LinkedIn, accept video ad content. Even Amazon runs sponsored brand videos on search result pages, which have higher click-through rates than display ads. You might need to customize your ad format depending on where you’re uploading the content. Ads that run on mobile apps, for example, will display better in a vertical format.
What’s the ideal resolution for video ads?
Most default video resolutions will work for ads, but 720 and 1080px are common for social media. While editing footage, your aspect ratios are also important, as the requirements vary across platforms. For instance, Facebook and Instagram use a 1:1 aspect ratio for carousel ads, a 9:16 aspect ratio for Instagram Stories, and a 4:5 ratio for news feeds. YouTube, in contrast, typically uses a 16:9 ratio, except for YouTube Shorts. Check your platform’s guidelines before making video ads. Fortunately, Captions makes modifying commercials for different social media sites easy.
