How to Make a Video Ad with AI (Step-by-Step Guide)

You no longer need a production crew, a shoot, or an editor to ship a video ad. With AI, a clear brief becomes a finished spot — scripted, storyboarded, voiced, scored, and rendered. The catch is that “a clear brief” is doing a lot of work in that sentence. This guide walks through the exact steps to get a great ad on the first try, and the small decisions that separate a generic result from one that performs.

Step 1: Write a brief, not a sentence

The model produces far better work from intent than from a bare topic. A strong brief names four things:

• The product — and the one thing it does better than the alternatives.
• The audience — who you’re talking to, and what they care about.
• The action — what a viewer should do (visit a page, book a demo, buy, install).
• The tone — energetic, premium, playful, deadpan, urgent.

Compare these two prompts:

“Coffee ad.”

“A 30-second ad for a cold-brew coffee brand aimed at busy morning commuters. Premium, calm tone. Show the product in real kitchen and on-the-go moments. End on the website and a ‘first bag free’ offer.”

The second gives the pipeline a strategy to execute. You’ll get a tighter script, more relevant visuals, and a real call to action.

Step 2: Pick the right format

Where the ad runs should drive its shape. Choose a video style that matches the channel:

• Vertical UGC (9:16) for TikTok, Reels, and Shorts — handheld, authentic, fast.
• Cinematic spot (16:9) for connected TV, YouTube pre-roll, or a hero section.
• Product showcase for a landing page or product-launch email.
• Square (1:1) or 4:5 for in-feed social where vertical real estate is limited.

The style sets pacing, look, voice persona, and structure, so you’re not specifying all of that by hand. If you’re new to the styles, the Video Styles catalog has an example and a one-click start for each.

Step 3: Let the pipeline plan before it generates

This is where AI ad tools differ. A good one doesn’t jump straight to pixels. Wavemaker first strategizes (angle, pacing, structure), writes the script, and builds a storyboard. Only then does it generate images — and it reviews each scene’s still image for quality and consistency before animating it into a clip. Catching a bad frame at the still stage is cheap; catching it after you’ve rendered video is not.

If you want to see and approve the plan before production runs, you can — the storyboard is surfaced as a draft you can edit.

Step 4: Ground the ad in your brand

A generic ad is forgettable. To make the ad unmistakably yours, give the pipeline your real brand assets:

• Paste your website URL and Wavemaker scrapes your colors, logo, and product photos, then grounds the visuals in them.
• Upload assets — a hero image, a product cutout, a logo — and they’re preferred over anything generated.

The result: the product on screen is your product, the palette is your palette, and the end card carries your logo. (Deep dive: Turn a Website URL Into a Branded Video.)

Step 5: Refine in plain language

The first cut is a starting point, not a take-it-or-leave-it. Don’t like scene three? Say so:

• “Make the opening hook punchier.”
• “Swap the music for something warmer and slower.”
• “Use our logo on the end card and add the website.”
• “Cut the third scene and tighten the pacing.”

Refinement edits the existing video instead of regenerating from scratch, so your good scenes stay put while the weak ones improve.

Step 6: Export for the channel

Export at the resolution and aspect ratio your channel needs. For broadcast and connected-TV, Wavemaker can hit frame-exact :15, :30, and :60 durations — the kind traffic systems require. For social, export the vertical cut. You can produce multiple aspect ratios from the same concept.

Common mistakes to avoid

• Being too vague. “Make it pop” gives the model nothing. Name the feeling and the moment.
• Over-stuffing a :15. Fifteen seconds holds one idea and one CTA, not five features.
• Skipping the brand step. If you have a URL or assets, use them — it’s the single biggest quality lever.
• Ignoring the hook. The first two seconds decide whether anyone watches the rest. Make them earn attention.

Put it together

The whole loop — idea to export — takes minutes, and every step is editable. Write the brief, pick the format, ground it in your brand, and refine until it’s right.
