Frequently Asked Questions

What is Video Extension and how does it work?

Video Extension uses the MAGI-1 AI model to seamlessly extend 10-second videos to 20 seconds. The AI analyzes your video's content, motion patterns, and visual style, then generates an additional 10 seconds that naturally continues the video. The extension maintains consistency with the original in terms of motion, lighting, and overall aesthetic.

Which videos can I extend?

You can extend any 10-second video generated with VEO 3.1 Fast, VEO 3 Fast, SORA 2, or SORA 2 Pro. The video must be exactly 10 seconds long to be eligible for extension. Videos generated with WAN 2.5, Seedance, or other models cannot currently be extended.

How much does video extension cost?

Video extension costs 8 credits per extension, regardless of the original model used or resolution. This is in addition to the credits used to generate the original 10-second video. For example, a VEO 3.1 Fast video (8-15 credits) + extension (8 credits) = 16-23 total credits for a 20-second video.

How long does the extension process take?

MAGI-1 video extension takes approximately 90-120 seconds to process. This is faster than generating a new video from scratch. You'll receive a notification when your extended video is ready, and it will appear in your video library.

Can I extend videos beyond 20 seconds?

Currently, video extension supports extending 10-second videos to 20 seconds only. You cannot extend a 20-second video to 30 seconds or beyond. However, we're working on supporting longer extensions in future updates. For now, the maximum video length with extension is 20 seconds.

What quality is the extended portion?

The extended portion maintains the same resolution as your original video. If you generated a 1080p video with VEO 3.1 Fast or SORA 2 Pro, the extension will also be 1080p. The extension seamlessly matches the visual quality, motion style, and aesthetic of the original video.

Can I extend image-to-video outputs?

Yes! As long as your image-to-video was generated with a compatible model (VEO 3.1, VEO 3, SORA 2, or SORA 2 Pro) and is 10 seconds long, you can extend it to 20 seconds. This works great for product videos where you want to show more angles or motion.

What if I don't like the extension?

If the extension doesn't meet your expectations, you can try extending a different generation of the same video or regenerate the original video and try again. Each extension attempt costs 8 credits. We recommend previewing your 10-second video carefully before extending to ensure you're happy with the content and motion.

Can I edit the video before extending?

Currently, you must extend the original AI-generated video without edits. The video extension feature works with the raw output from VEO or SORA models. If you've downloaded and edited a video externally, you cannot re-upload it for extension. The extension must be applied to the original 10-second generation.

Which aspect ratios does extension support?

Video extension supports all aspect ratios: 9:16 (vertical for TikTok/Reels), 1:1 (square for Instagram), and 16:9 (horizontal for YouTube). The extended portion will maintain the same aspect ratio as your original video.
