| Capability | Free tier | Paid plan |
|---|---|---|
| Resolution | Capped, often 720p | Up to 4K |
| Clip length | Short | Longer |
| Watermark | Often applied | Removed |
| Commercial rights | Limited | Granted |
Paid plans raise resolution and length and remove the watermark a free AI video generator applies. Choosing between a free tier and a paid plan depends on output length and quality — covered in how to choose.
An AI video generator differs from a manual video editor: it generates new footage from a prompt, while an editor assembles existing clips, and an AI marketing tool uses that video in a campaign. Knowing what an AI video generator comprises lets a creator choose the right one per use case.
AI video generators work by predicting and rendering video frames from your prompt using a trained diffusion model. An AI video generator reads a text prompt or image, generates frames that match it, and stitches them into a clip — resolution and length depend on the model and the plan.
Choosing the right AI video generator means matching use-case fit, output realism and resolution to your project. An AI video generator is best judged against eight selection criteria.
Matches text-to-video, avatars, editing or social.
Produces believable, artefact-free footage.
Renders the quality and clip length you need.
Returns value at the free or paid price.
Supports presenters and narration.
Grants rights to use the output commercially.
Generates without a steep learning curve.
Produces a clip in a workable time.
Weigh realism, resolution, commercial licence and pricing against each AI video generator's limitations — the constraints every tool carries, covered next.
AI video generators fall short across four areas: realism artefacts, clip length, consistency, and cost — an AI video generator can warp hands, faces or text, caps clips at a few seconds on most models, drifts across shots, and runs up rising credit costs.
Usually — most AI video generators grant a commercial licence on paid plans, but rights vary by tool and by the training data, so check each vendor's terms. Tools like Synthesia and Runway document commercial use on paid plans.
Only with consent — generating a real person's likeness without permission can breach publicity, defamation and, where in force, deepfake laws. Check publicity-rights and deepfake legislation in your region, and use only consented or licensed likenesses.
Use real footage for brand films, authentic testimonials, and high-stakes ads, where authenticity and trust matter — work an AI video generator cannot do reliably:
