Buyer’s guide
How to choose an AI video tool
Video AI covers three different jobs: generating new footage, creating presenter videos with avatars, and editing or repurposing what you already filmed. Know which one you need before you compare tools.
- Pick the job. Generation, avatars and editing are separate tool types.
- Check credits and length. Most plans limit clip length, resolution and monthly credits.
- Watch for watermarks. Free plans often add watermarks or block commercial use.
- Get consent. Only clone voices or faces you have clear permission to use.
