Upload a short video and continue the scene from where it ended: the action, the story, or the camera movement. Enter a prompt describing what happens next and generate up to 30 seconds of new footage while maintaining the characters, setting, and visual style of your original clip. Make a video longer for social posts, story scenes, ads, and cinematic shots without filming from scratch. No sign up is required to start.
This AI video extender is for one job: make it longer without rebuilding the opening shot. Upload a video, describe the continuation, and generate new footage that follows the original scene.
Add up to 30 seconds of newly generated footage to your original clip. Turn brief moments into longer scenes without recreating the beginning or recording additional footage.
The clip you upload is the reference to video generation. Models read the last frames and keep the people, objects, lighting, and motion consistent. The last-frame read is a video frame extender AI pass. What you get is reference video to video AI: the next shot is written from footage you already have, not from a blank prompt.
Guide the video continuation using simple text. Describe the next character action, scene development, camera movement, or environmental change. Video continuation AI follows that prompt. It also works as an AI video generator extender: the generator only writes the next seconds.
Upload an MP4 or MOV video, then select the exact clip you want to extend. Your selected input footage can be up to 30 seconds long. The first run does not require an account.
Enter a prompt explaining the next action, scene, or camera movement. Choose how long to extend video time, plus resolution and audio. On supported models you can output 4K, so the same flow works as a 4K video extender when you need a larger frame.
Click Create to generate the continuation. Preview the complete video with the original and extended footage, then download the finished result.
People looking for the best AI for long videos often already have a take they like. Extend that clip instead of generating a long video from nothing.
Extend short clips for TikTok, Instagram Reels, and YouTube Shorts. Continue actions, reactions, transformations, and reveals to create more engaging content without recording another take.
Video Extend is an AI video extender that adds newly generated footage after the ending of an existing video. It analyzes the uploaded clip and follows your prompt to create the continuation—an AI video expansion of the original scene, not a separate video.
Upload a video and describe what should happen next. The video extender AI studies the original characters, setting, objects, motion, and visual style, then generates the new footage from that reference.
Your selected input video can be up to 30 seconds long. If the uploaded file is longer, you can trim it and choose the section you want to use.
You can extend video duration by up to 30 seconds. The available options may vary depending on the selected AI model.
No. The extension length is not dynamically reduced based on the input duration. A 5-second or 15-second input can both extend length by up to 30 seconds, subject to the selected model.
The complete video contains the original input and the generated extension. With a 30-second input and a 30-second extension, the combined video can be up to 60 seconds long.
Video Extend supports MP4, MOV, M4V, and WEBM files.
Yes. You can select the exact section you want to use before generation. After trimming, you can also choose Re-trim to adjust the selected segment again.
Describe what should happen after the original video ends. You can specify character actions, scene changes, object interactions, camera movements, atmosphere, or the next story event.
Supported models can preserve important details such as character appearance, clothing, environment, and visual style. Clear footage with visible subjects generally provides better continuity.
Yes. You can preview and download a complete video containing the selected original clip followed by the AI-generated extension.
Yes. You can use a completed result as the input for another extension. Keeping each prompt focused on the next immediate action can help maintain better continuity.
A Faster Way to Finish Short Videos
I often have clips that end before the action feels complete. I just needed the video longer—make it more long, honestly—and Video Extend lets me describe the next moment without shooting everything again.
Turned One Clip into a Complete Story
I uploaded a short character scene and treated it like an AI video expander. It continued the interaction until I had enough footage for a complete short story.
Useful for Product Campaigns
We extended a short product shot into a longer promotional sequence. It saved us from arranging another shoot just to capture a few extra seconds.
Simple Prompt-Based Control
I like that I can explain what should happen next instead of a complicated timeline. I tried the AI video extender free, no sign up, and I didn't install an app to extend video length. I also didn't need Grok extend video or a ComfyUI extend video graph.
Better Use of Travel Footage
A drone clip from my trip ended too soon, so I used Video Extend to continue the camera movement. I exported 4K when I needed an AI video size extender for the cut. The longer result worked much better in my travel edit.
Helpful for Testing Story Ideas
I use it as an AI video continuer to try different ways a scene could go. If I already have a take, that is more useful than hunting for the best AI for long videos from scratch. Kling extend video is the same job; I just stay in the browser.
