Real results

One clip, extended by each AI video extender model

The same 8-second clip, extended once by each model with the same instruction: the whale glides past the coral and swims off into deep water as small fish scatter. These are unedited outputs from October 4, 2026; the new footage starts at 0:08. Veo 3.1 Fast keeps the same shot rolling, while both H3 models continue from a new camera angle.

How it works

How to extend a video with AI in three steps

  1. 01

    Upload your clip

    MP4 or MOV, 2–60 seconds, up to 50 MB. The workspace checks the length and size before anything is charged.

  2. 02

    Choose a model and length

    H3 Max Turbo and H3 Max add 5, 10 or 15 seconds. Veo 3.1 Fast adds 7 seconds. Describe what happens next.

  3. 03

    Extend and download

    Check the exact credit price, start, and download the extended MP4 when it is ready. Credits come back if a job fails.

What you get

An AI video extender that keeps the scene going

AI Video Extender continues an existing video instead of starting from scratch. The model reads the last moments of your clip, keeps the same subjects and setting, and generates new footage that follows on: Veo 3.1 Fast carries the same shot forward, while the H3 models usually continue with a new camera angle, like the next shot in an edit. You get one MP4: your original clip with the extension joined to the end.

01

Continues your own footage

The extension starts from the last frames of your clip, so the same subjects, place and light carry on. Choose Veo 3.1 Fast for one unbroken shot, or H3 for a follow-on shot from a new angle.

02

You decide what happens next

Describe the next action in plain words, or leave the box empty and the model simply continues the scene.

03

One MP4, ready to post

You download a single video: your original clip followed by the new seconds, at 768p, 720p or 1080p depending on the model.

Know before you upload

Which clips extend well

The three models trade cost, length and style of continuation. All of them start from the end of your own footage; they differ in how much they add, which clips they accept and whether they keep the same shot or move to a new angle.

Works well

  • Clips that end mid-motion: a walk, a pan, a drone shot (Veo keeps the shot going)
  • B-roll that needs a few more seconds to fit the edit
  • Product and nature shots with one clear subject
  • AI-generated clips you want to take further

Harder to extend

  • Hard cuts or scene changes right at the end
  • Readable text, logos and faces close to camera: details can drift
  • Fast action with many people, where continuity is hard to hold
  • Clips shorter than 2 or longer than 60 seconds

Pricing

What the AI video extender costs

You pay in credits for the seconds you add, never for the length of your original clip. The exact price is shown after upload and before anything is charged, and credits are returned if a job fails. Each job rounds up to whole credits. New accounts get 6 free credits.

Questions

AI video extender FAQ

What is an AI video extender?

An AI video extender adds new footage to the end of an existing clip. Instead of generating a video from a prompt alone, the model studies how your clip ends and continues it, keeping the same scene, subjects and camera movement.

How do I extend a video with AI?

Sign in, upload your clip to the AI video extender at the top of this page, choose a model and how many seconds to add, and optionally describe what happens next. The exact credit price is shown before you start. When the job finishes, download the extended MP4.

Which videos can I extend?

MP4 or MOV, 2–60 seconds, up to 50 MB, at least 256 pixels on each side and no wider than 5:2 or taller than 2:5. H3 Max Turbo and H3 Max accept any such clip. Veo 3.1 Fast needs a 16:9 or 9:16 clip at 720p or 1080p.

How long can the extension be?

H3 Max Turbo and H3 Max add 5, 10 or 15 seconds per job. Veo 3.1 Fast adds 7 seconds. To go further, extend the result again: each job continues from the end of the video you upload.

Which model should I choose?

Choose Veo 3.1 Fast when the extension should look like the same shot simply kept rolling; it adds 7 seconds and accepts 16:9 or 9:16 clips at 720p or 1080p. Choose H3 Max Turbo or H3 Max when a follow-on shot is fine: in our tests both usually continued the scene from a new camera angle. H3 Max Turbo is the cheapest and fastest, and H3 Max is MiniMax’s full model at twice the rate. The side-by-side examples on this page show all three on the same clip.

What happens to the sound?

Your original soundtrack stays on the original part. All three models also generate sound for the added seconds, matched to what happens on screen. If you do not want it, mute or replace the audio in your editor.

How much does the AI video extender cost?

In credits per added second, by model and output size: H3 Max Turbo 1.2 at 768p and 2.2 at 1080p, H3 Max 2.2 and 4.2, and Veo 3.1 Fast 4. Each job rounds up to whole credits, so a 5-second H3 Max Turbo extension at 768p costs 6 credits. Your original clip is not charged. New accounts get 6 free credits, enough for that first extension. Credits are returned if a job fails.

How long does the AI video extender take?

Usually one to five minutes, depending on the model, the length you add and how busy the provider is. You can leave the page; the result is saved to your account history.

What happens to my video?

Your clip is stored in your account so it can be sent to our video model provider and the result can be delivered. You can delete your account data at any time. Upload only videos you have the right to edit.
