Mina LabsAI Video Extender
An AI video extender carries on a clip you already have: the same scene, the same light and the same subject, continuing from the last frame into whatever you describe next. Upload the video, write what happens after it ends, and choose how many seconds to add. Seedance 2.5 Video Extend adds 4 to 30 seconds to a clip of up to 30 seconds, with sound, at 480p or 720p. MiniMax H3 Max Extend Video adds 5 to 15 seconds to a clip of up to a minute, renders up to 2K, can crop the continuation to a new aspect ratio, and can hand back the whole video or only the new part. Flux 3 Extend Video is a third option at 720p or 1080p. Each is priced by the second, and the exact number is on the Generate button before you spend.

Seedance 2.5 Video Extend adds 4 to 30 seconds to a clip up to 30 seconds long. MiniMax H3 Max Extend Video adds 5 to 15 seconds to a clip up to 60 seconds long, at up to 2K.
Will the new part match my video?

Can I change the aspect ratio while extending?

How is it priced?
By the second, on your clip and the seconds you add. The exact price is on the Generate button before you spend, and a failed generation is refunded automatically.
