Types of AI Videos You Can Create

Not all AI video tools do the same thing. Before picking a tool, decide what type of video you actually want to make.

Choosing the Right Tool

Pick based on your video type and technical comfort level:

  • Complete beginner, wants a presenter - Start with Synthesia or HeyGen. Sign up, paste your script, pick an avatar, generate. That is literally the whole process.
  • Content repurposer (blog posts to video) - InVideo AI or Pictory. Paste your article, AI assembles the video.
  • Social media creator - CapCut AI. Free, fast, mobile-friendly, built for vertical video.
  • Wants creative cinematic clips - Runway Gen-3. Steeper learning curve but best visual quality.
  • Does screen recordings and tutorials - Descript. The transcript-editing workflow changes everything.

Creating Your First AI Video

Let us walk through making a real video from start to finish using Synthesia as the example. This process applies to most avatar-based tools.

  1. Sign up and explore free features - Synthesia offers a demo video. HeyGen gives one free video. Use the free option to test quality before paying anything.
  2. Write a focused script - Keep your first video under 2 minutes (about 300 words of spoken text). Short scripts are easier to nail and reveal any issues quickly. Write conversationally - the way people actually talk, not the way they write emails.
  3. Choose your avatar - Pick one that matches your audience and content tone. Business content generally calls for a professional-looking presenter. A casual lifestyle brand might use a more relaxed avatar. Most tools show a preview so you can check before generating.
  4. Select a template or layout - Most tools have pre-built layouts with text overlays, side panels, and lower-third title cards. Pick one and customize the colors to match your brand.
  5. Add your script to the text box - Type or paste it. The tool will generate the avatar speaking your words. Add pronunciation guides for unusual words using the phonetic spelling option if available.
  6. Preview and adjust - Play the preview. Check lip-sync, pacing, and that the script sounds natural spoken aloud. Adjust speaking rate (most tools have a speed slider) if it sounds rushed or too slow.
  7. Generate the final video - Hit render. This takes 2-10 minutes depending on the tool and video length. Download the MP4 when done.

Pro Tip

Read your script aloud before generating. If you stumble on a sentence while reading it, the AI will too. Rewrite any awkward phrasing before submitting to generation.

Adding Voiceover and Music

Most avatar tools include text-to-speech voiceover built in. But if you want higher quality voice, there are better specialized options.

Built-in TTS: Good enough for most corporate and educational content. Synthesia and HeyGen have noticeably better voices than InVideo's built-in options.

Dedicated voice tools:

  • ElevenLabs - Best TTS quality available. Can clone your own voice with 3 minutes of audio. Pricing from $5/month.
  • Murf.ai - Large voice library with good pronunciation controls. Great for e-learning content.
  • Play.ht - Good voice quality, competitive pricing, long-form friendly.

Background music: Use royalty-free music libraries to avoid copyright issues. Epidemic Sound ($15/mo), Artlist ($200/year), or YouTube's Audio Library (free). Avoid using popular songs - even if you think it is covered by fair use, it usually is not.

Did you know? Adding custom avatars increases viewer trust by 35%. Vertical video (9:16 format) gets 2x more engagement on mobile platforms.

Editing and Refinement

Avatar video tools do not offer traditional frame-by-frame editing. What they do offer is script-based editing - you change the words and regenerate. This is both simpler and more limited than traditional editing.

What you can typically edit without regenerating:

  • Background images and colors
  • Text overlays, titles, and captions
  • Music track and volume
  • Transition effects between scenes
  • Aspect ratio (portrait vs landscape)

What requires regenerating:

  • Any changes to the spoken script
  • Changing the avatar
  • Changing the voice or language

For more flexible editing after generation, export the video and bring it into CapCut, DaVinci Resolve, or Descript for additional editing. This two-step workflow (AI generates, you polish) produces the best results.

Exporting for Different Platforms

PlatformFormatResolutionAspect Ratio
YouTubeMP41920x1080 minimum16:9 horizontal
TikTokMP41080x19209:16 vertical
Instagram ReelsMP41080x19209:16 vertical
LinkedInMP41280x720 minimum16:9 or 1:1
Twitter/XMP41280x72016:9 or 1:1

Most AI video tools let you choose aspect ratio before generating. Always match the ratio to your target platform. A horizontal video on TikTok gets letter-boxed and looks amateurish.

Common Mistakes to Avoid

  • Too long for the platform - TikTok and Reels viewers lose interest after 60-90 seconds. Keep first videos short and test engagement before going long.
  • No captions - Most social video is watched without sound. Always add captions. Most tools have auto-caption generation.
  • Generic template with no customization - If you use the default template without changing colors or fonts to match your brand, your video looks like every other AI video from that tool.
  • Script that reads like writing, not speech - "Furthermore, it is worth noting that..." sounds awful when spoken aloud. Write how you actually talk.
  • Ignoring platform disclosure rules - YouTube, TikTok, and others require you to disclose AI-generated content. Check platform guidelines and disclose appropriately.

Next Steps and Advanced Techniques

Once you have made your first video, here is what to learn next:

  1. Create a custom AI avatar of yourself - HeyGen and Synthesia let you train a personal avatar with 2-5 minutes of recorded footage. This builds authenticity while keeping the AI convenience.
  2. Try multi-scene videos - Add visual variety by cutting between different scenes, screen recordings, and animated text slides. Single-scene talking-head videos for 5+ minutes feel monotonous.
  3. Experiment with B-roll from text-to-video - Use Runway or Pika to generate 5-second visual clips that illustrate your points. Cut them in during editing for a more polished result.
  4. Test different AI voices - Try ElevenLabs voice cloning. Having your own voice on an AI avatar feels more authentic to viewers.
