# How to Create a Product Demo Video Without a Film Crew

> Produce a professional product demo video using just your phone, with Captions Camera, Prompt to Video, B-roll overlays, and auto-generated captions.

Product demos used to require a camera operator, lighting setup, and a post-production editor. With Captions you can produce a polished demo video with just your phone, whether or not you want to be on camera.

## Plan your demo

Before you record anything, answer one question: what is the single thing this demo needs to show? The best product demos focus on one feature or benefit, not the whole product. A 30-60 second runtime is ideal for social distribution.

Write a short script before you start. Even a rough bullet-point outline will make your recording faster and your final video more focused.

## Record or generate your talking head

<Steps>
  <Step title="Option A: Record with Camera and Teleprompter">
    Open **Camera** in Captions, paste your script into the teleprompter, and record. The vertical 9:16 format works for TikTok, Reels, and YouTube Shorts. You don't need a studio. A clean wall and decent window light is enough.
    <Tip>Record 2-3 takes and use the best one. The teleprompter keeps your eyes on the lens and your pacing consistent.</Tip>
  </Step>

  <Step title="Option B: Use Prompt to Video (no camera needed)">
    If you'd rather not be on screen, open **Prompt to Video**, write or paste your script, choose an actor (or your AI Twin if you've set one up), and generate. Captions produces a realistic talking-head video synced to your script, with no filming required.
    <Tip>Prompt to Video requires a Max or Scale plan. See the AI Twin setup guide to create an avatar that looks like you.</Tip>
  </Step>
</Steps>

## Add product visuals as B-roll

<Steps>
  <Step title="Gather your product footage">
    Record a close-up of your physical product, take screenshots of your app or dashboard, or use screen recordings to capture your product in action. These become your B-roll overlays.
  </Step>

  <Step title="Add media overlays in the editor">
    In the Captions editor, tap **Media** and import your product images or clips. Position them over your talking-head footage at the moments you're describing that feature. Resize and reposition to fit.
    <Tip>Screen recordings work especially well for software products. They show the product actually working, not just described.</Tip>
  </Step>

  <Step title="Add a CTA text overlay at the end">
    Use a text overlay in the final 3-5 seconds to show your price, a discount code, or a call to action like "Link in bio." Keep it short and high-contrast.
  </Step>
</Steps>

## Polish the audio and captions

<Steps>
  <Step title="Remove background noise with Denoise">
    If you recorded at home or in a noisy environment, tap **Denoise** in the audio settings. This removes air conditioning hum, keyboard noise, and ambient room sound.
  </Step>

  <Step title="Generate captions">
    Tap **Captions** to auto-generate a caption track. Most product demo viewers watch without sound, so captions keep them watching. For demos, choose a clean, readable style like Byline or Blueprint rather than a flashy animated style.
    <Tip>Review the captions for any product names or technical terms that the AI may have misspelled.</Tip>
  </Step>
</Steps>

## Export and post

Tap **Export**. Choose 1080p for social platforms. Your captions are burned into the video by default, or you can export an SRT file if you're uploading to YouTube or LinkedIn separately.

## Tips

* Show the product actually working. Don't just describe what it does
* Screen recordings are the most convincing B-roll for digital products
* 30-60 seconds is the sweet spot for demo videos on social platforms
* A clean caption style reads better than an animated one when the goal is clarity
* Record in a quiet space even if you're using Denoise. The cleaner the source, the better the result
