How to make a marketing video with AI, step by step

By the Qevio team · · 9 min read

A marketing video used to mean a shoot, an editor and a few weeks. With AI you can go from an idea to a finished short video in an afternoon: write a short script, generate each scene, then put it together with captions and music. This guide covers the whole process for the most common marketing videos, such as product promos, launch teasers, explainer clips and social ads, with a script template, prompt tips and a review checklist.

Decide the goal and the channel first

Every choice in the video follows from what it's for and where it will run. A 15 second Reel to drive sales looks nothing like a 30 second landscape video on your homepage. Write down the goal (awareness, sales, sign-ups, education), the channel (TikTok, Instagram, YouTube, your website, an email) and the audience before you write a word of script.

Choose the type of marketing video

Most short marketing videos fall into a few types, each with its own structure.

  • Product promo: show the product, the main benefit and the offer. Best for ads and product pages.
  • Launch teaser: build curiosity with mood shots and a date, without showing everything.
  • Explainer: a problem, how the product solves it, and the result, in three or four scenes.
  • Brand video: mood, values and atmosphere more than features. Good for websites and YouTube.
  • Seasonal or sale video: the offer and the deadline, repeated clearly.
  • Creator-style (UGC) clip: a natural, handheld look, as if a real person filmed it. Keep it honest.

Write a short script with a scene list

Even a 15 second video benefits from a script. Write it as a list of scenes, each with what we see and what (if anything) is said or shown as text. Keep each scene to one action. This list becomes your prompts.

A simple 15 second product promo template:

  • Scene 1 (0 to 3 seconds), hook: the product in motion or the problem it solves. Text: the hook line.
  • Scene 2 (3 to 8 seconds), benefit: the product in use, close up. Text: the main benefit.
  • Scene 3 (8 to 12 seconds), proof: a detail, a result or a feature that backs the benefit up.
  • Scene 4 (12 to 15 seconds), call to action: the product hero shot with the offer and what to do next.

Generate each scene as its own clip

AI video models are strongest with one scene and one camera move at a time. Turn each scene in your list into a prompt that names the subject, the setting, the action, the camera and the light, and generate it as a short clip. Keep the setting, light and colours the same across scenes so the finished video feels like one piece.

If the video must show your real product, use a product photo as the first frame for the product scenes. Text-only prompts are fine for mood shots, backgrounds and lifestyle scenes where the exact product doesn't appear.

Add on-screen text, captions and music

Most people watch social video with the sound off, so on-screen text and captions carry the message. Add them in an editor rather than asking the AI to generate text inside the video, which often comes out garbled. Keep text short, large and inside the safe area of the frame.

Music sets the pace. Use music you have the rights to, or the licensed audio inside each social platform's app. If there is a voiceover, add subtitles so the video still works on mute.

Make versions for each channel

Once the main video works, make the versions each channel needs. A vertical 9:16 cut for TikTok, Reels and Shorts, a 4:5 or 1:1 cut for feeds, and a 16:9 cut for YouTube and your website. Generating scenes in the right shape from the start gives better results than cropping a landscape video into a vertical one.

It's also worth making a shorter cut. A 6 to 10 second version of a 30 second video is useful as an ad, a Story or a teaser.

How to make a marketing video with Qevio

In Qevio's AI Video Generator, describe a scene, pick a length of 5, 10, 15, 20 or 30 seconds (depending on the model), a resolution and a shape (9:16, 1:1, 4:5, 16:9 or 21:9). Attach a JPG, PNG or WebP product photo up to 10 MB to use it as the first frame. Choose a quality mode: Fast to test, Cinematic for brand films, Product Ad to keep a product accurate, or Realistic for creator-style footage. The credit price is shown before anything runs, and you can ask for changes in the same chat.

To get the video together with images, a caption, hashtags, Content Write and a call to action, use the AI Campaign Generator. If you already have your own footage, the Auto Video Editor cuts it into a short edit with captions and music, and Qevio's video tools can add subtitles and effects to a finished video. Brand Kit keeps your colours, voice and logo consistent.

What to do outside Qevio

Download the MP4s and assemble multi-scene videos in your usual editor if you need precise timing, exact on-screen text or your own music. Qevio doesn't post videos for you, so upload the finished video to each channel yourself.

Review checklist

Watch the finished video on a phone, with the sound off and then on.

  • The message is clear in the first two or three seconds.
  • The product looks like the real one in every scene.
  • Nothing looks odd in faces, hands, text or backgrounds.
  • Captions are readable and inside the safe area.
  • Claims, prices and dates are correct.
  • You have the rights to the music and any uploaded footage.
  • The call to action is clear and matches the goal.

How long does it take?

For a 15 second product promo, expect roughly half an hour to write the script and prompts, a short wait for each clip to generate, and some time to choose the best takes and assemble them. Most of the time saving comes from not needing a shoot or a location, and from being able to remake any scene in minutes.

Questions

Yes, for short videos. Generate each scene with AI, then add on-screen text, captions and music. For long videos with many scenes, an editor helps assemble the clips.
