Imagine that you shot an interview and later realized you need a quick cameo from a colleague, or you're producing a product demo and want a presenter in the scene, but they weren't available on the day of shooting. Perhaps you're creating a skit and need to drop a character into a background. These are the real issues that can be solved by painstakingly using VFX software to add a person to a video manually, but today, there is a faster solution.

You can add a person to a video with AI in a few simple clicks without any re-shoots. If you've used AI to add people to photos, the same thing is now possible for videos.

Concerns of Using AI to Add People to Videos

Adding people to videos with AI is powerful, but with great power comes great responsibility. Use this quick checklist to keep your edits legal, ethical, and high-quality.

  • Consent, likeness, and platform policies: Make sure that you have permission from the people you are inserting, especially if they are famous.
  • Copyright and assets: Only use footage, photos, or model assets that you have the rights to use. If you're inserting a subject from a photo or another clip, confirm that your license covers derivative works and commercial use. As a general rule, you can avoid logos, artwork, or locations that are clearly someone else's intellectual property.
  • Realism and scene matching: If the video is to be believable, the lighting, perspective, scale, and contact of the added object need to be spot on everywhere.
  • Safety, context, and brand integrity: Avoid placing people into scenes that could be misleading, harm reputations, or imply certain endorsements.
  • Quality and export: Use the highest-quality sources.

Conclusion

Traditionally, putting a new person into a video meant advanced compositing or a complete reshoot. Now, AI lets you solve the issue without breaking your workflow. Filmora's new AI tool is designed for this. It keeps everything inside one editor, gives you instant previews, and removes the need for manual masking and complex setups. Use it to add a missing presenter, craft a quick cameo, or tidy up a scene.

And, don't forget to do it responsibly, with permission and clear context.
