Video length varies by platform: Kling AI leads with 2-minute generations, Runway ML offers 10-second clips (extendable), Pika Labs generates 4-second videos (extendable), and Luma AI creates 5-second clips. Most platforms allow extending videos by generating additional segments.
Do AI video generators have copyright restrictions?
Generally, you own the rights to videos you generate using your own prompts and content. However, review each platform’s terms of service carefully. Synthesia and HeyGen provide clear commercial usage rights, while some platforms have restrictions on certain types of content or require attribution.
