Frequently Asked Questions
Learn how to use the Video Extend tool efficiently
What is the Video Extend tool?
Video Extend uses AI to continue your existing video by generating new frames that flow naturally from the ending of your clip. You define what happens next and the system handles the rest.
How does the AI know how to extend the video?
The AI analyzes the ending frames of your video—motion trajectories, lighting, subject position—and then predicts and synthesizes additional footage that matches scene context and style.
How long can I extend my video?
Extension length depends on clip complexity, style, and resolution. Typically you can add from a few seconds to longer durations depending on your plan and selected settings.
Will the extended part match the original footage in style and motion?
Yes. Video Extend ensures that visual style, lighting, camera movement and subject motion remain consistent so the extended footage looks like an integral part of your story, not a separate add-on.
Which formats and resolutions are supported?
The tool supports standard video formats (e.g., MP4) and common resolutions suitable for social media, HD & beyond. For higher output quality or longer durations, check the premium plan options.
What kinds of projects is Video Extend ideal for?
