Frequently Asked Questions
How does the AI video extender work?
It uses "Generative Outpainting" technology. The AI analyzes the last frames of your video and your text prompt to predict and generate new frames that logically follow the original action.
Can I control what happens in the extended part?
Yes! Use the "Prompt" box in the tool to describe the action. For example, if your video shows a car driving, you can type "car enters a tunnel" to guide the extension.
What is the difference between Extension and Slow Motion?
Extension adds new time to the video by generating new events (making the story longer). Slow Motion stretches existing time by adding intermediate frames (making the action slower). WeryAI does both.
How long can I extend a video?
You can extend a clip by 5 seconds at a time (as seen in the "Extension Duration" setting). You can repeat the process to create longer sequences.
Is it free?
Yes, WeryAI offers free credits to try video extension and slow motion effects.
