Upload a clip, describe what happens next, and continue the motion from there.
Clip ends too soon? Upload it, write what happens next, and the AI video extender picks up from the final frame. The same people, the same light and the same camera move carry on, so the new seconds feel like part of the original shot rather than a new clip glued on. It is an AI video extender free to start, with no sign up and no restrictions on how you describe the next move.
A 4-second clip of a bikini model at a waterfall ends mid-turn. The video extender adds 4 more seconds: she sinks into the water, rises and winks.
Prompt: Continue the scene. She sinks to her shoulders, rises with water streaming off her hair and ends on a slow wink.
The upload ends with a puppy sneezing at a tub full of foam. Extend scene, and it dives right in and pops up wearing a bubble beard.
Prompt: Continue the scene. The puppy dives head-first into the bubble bath and pops up with a foam beard and a foam hat.
From social posts to ads, here is where people use AI video expansion the most.
Your nightclub spin cuts off at the best moment. Extend video clip by a few seconds and let her finish the move. A free NSFW video extender for glam and party content within our rules.
Most tools that make a video longer just loop or slow it down. Video continuation AI writes new motion that matches what came before, so you can expand video AI clips into real scenes.
As a video frame extender AI, it starts from your last frame, so faces, outfits and lighting stay the same. It works for slow sensual clips as well as fast action, and is open to mature scenes within our rules.

My AI clips always stopped right when it got good. Now I upload the clip, write one line about what happens next, and the scene just keeps going. You cannot see where the new part starts.
I make swimwear and dance content. Four seconds is never enough for a slow turn. With the video extender I add a few seconds and the model, the outfit and the light all stay the same.
Ad slots need 6 or 10 seconds and my product shots were 4. Extending the clip saved me a reshoot more than once. It is now part of my normal workflow.
I used to set up a ComfyUI extend video workflow for this. Here I just upload and click. Same idea, none of the setup.
My pet clip cut off before the funny part. I extended it and wrote the ending myself. It got more views than anything I posted that month.

It makes a video longer by generating new footage that starts where your clip ends. The AI reads the last frame and the motion, then continues the scene with the same look.
Upload your clip, describe what should happen next, pick how many seconds to add and press generate. You get the original and the new part as one video.
You can start free and try it with no sign up. Longer extensions or higher resolution use credits, and the cost is shown before you generate.
Each run adds a few seconds, depending on the model. To extend video duration further, run it again from the new ending. This is the best way to build long AI videos without losing consistency.
It works the same way: you continue a clip from its last frame. If you searched for Grok extend video or Kling extend video and want to do it online without installing ComfyUI, you can do it here.
Mature and sensual clips such as swimwear, lingerie and dance are fine, and your prompt is not secretly rewritten. Explicit exposure, intimate acts and content of real people without consent are not allowed.
You can choose the output resolution the model offers, up to 1080p on supported models. A 4K video extender option and an AI video size extender for changing the frame ratio are not available yet.
To build a new clip from images, video and audio references, use our reference video to video AI tool. The AI video generator extender is for continuing one clip you already have.
