What is AI Video Extender?
AI Video Extender is a Veo 3-powered tool designed to seamlessly lengthen existing generated clips. Instead of restarting from scratch, it appends new segments while maintaining consistency in style, lighting, motion, and story continuity. It returns a single merged video file, allowing longer and more cohesive storytelling workflows.
Frequently Asked Questions
Learn how to use AI Video Extends to create longer, cinematic stories.
How does this Veo 3-powered AI Video Extender work?
This Veo 3-powered extension workflow takes your existing video clip and a new prompt to generate a continuation. It analyzes the final frames of the source video so the new segment matches the original style, physics, and camera movement as smoothly as possible.
Can I extend any video file?
For best results, we strictly recommend using videos originally generated by Veo 3 (or Veo 3.1). Uploading non-Veo footage may result in generation failures or audio-visual inconsistencies.
How long can I extend a video?
Each extension adds a fixed unit of 7 seconds. You can chain up to 20 extensions in a row, allowing for a maximum total video length of 148 seconds (original clip + extensions).
Does the extension include audio?
Yes. In supported Veo 3-powered extension workflows, synchronized audio can be generated for the new segment and aligned with the original track for a more seamless result.
What is the 'True Continuation' feature?
Unlike restarting a generation, 'True Continuation' ensures that the subject, background, and lighting remain consistent. It builds upon the previous context, making it perfect for storytelling or extending hero shots without visual breaks.
What resolutions are supported for extension?
To ensure stability and quality, the input video must be in either 720p or 1080p resolution, with an aspect ratio of 16:9 or 9:16.
Do I get two separate video files?
No. The AI Video Extends tool returns one single, merged MP4 file containing both your original footage and the new extension, ready for immediate use.
