Frequently asked questions
Can I use AI video commercially?
Under paid plans of Runway, Luma, Pika, and Sora, commercial use is permitted under each platform's terms. Always read the specific terms for the plan you're on. Kling's licensing for Western commercial use is less polished — verify before relying.
Why did Sora take so long to release?
OpenAI cited safety, deepfake, and consent concerns. The February 2024 announcement showed striking demos; broad availability followed over an extended period as OpenAI worked through provenance markers and policy frameworks. The slow rollout reflects the same concerns we discussed in our AI voice clone ranking.
How long are typical AI-generated videos?
Most consumer tools generate 5-20 second clips per generation. Multiple generations can be stitched. Long coherent narrative video remains technically challenging for all current platforms. Don't expect to generate full short films from a single prompt.
Is AI video really replacing stock footage?
For specific shots described precisely, often yes. For complex multi-element scenes, stock footage still wins on quality and predictability. The cost-quality curve is shifting toward AI for many use cases — quickly.
What about deepfakes and consent?
All platforms in this ranking restrict deepfake creation of identifiable people through terms of service. Enforcement varies. Detection of AI-generated video is improving but it's an arms race. For commercial use involving any recognizable person, treat AI video the same as you would AI voice — explicit consent or don't do it.
