AI Video Extender
The AI video extender on Wandura continues a clip from its last frame with Grok Imagine Extend, following a prompt for what happens next. Your clip ends too soon? Upload it, describe what happens next, and AI generates a seamless continuation — 4 to 8 extra seconds that pick up exactly where your video left off. The credit cost depends on how many seconds you add and is shown before you create (1 credit = $0.01).
Make Any Video Longer Without Reshooting
Video Extend analyzes the last moments of your clip — subject, motion, lighting, camera — and generates new footage that continues the scene according to your prompt. Wandura runs it on Grok Imagine Extend at a flat 10.6 credits (about $0.11) per second of generated video, shown in the widget before you spend anything. Feed it a 2–15 second source clip and choose how many seconds to add; the result lands in your Creations as a normal video you can download or extend again. The pair playing here is a real generation: a 5-second source clip on the left, the same clip with 6 AI-generated seconds added on the right.

Extend a Clip Beyond Its Original End
AI video extension continues a clip past its final frame, giving you the extra seconds a cut needs without regenerating the whole shot. It is handy when a generation ends a beat too early, or when you need a longer hold for a caption or logo.
Extend in small steps rather than one long jump — shorter continuations keep the motion and subject coherent. Then trim to the exact length your edit calls for.
1 AI Model, One Video Extend Tool
Continue the Scene, Keep the Look
The continuation inherits the visual DNA of your source clip: the same subject, palette, motion direction and framing carry into the new frames. Your prompt steers what happens next — the camera keeps pushing in, the character turns around, the wave finally breaks — so the extension feels shot in one take rather than glued on — the clip playing here is a real extended result, 5 original seconds continued by 6 generated ones.
Try AI Video ExtenderBeat the AI Generator Duration Cap
Most AI video models stop at 8–10 seconds per generation. Extend is the way past that ceiling: generate a base clip with Text to Video or Image to Video, then feed the result back through Video Extend to add another 4–8 seconds — and repeat. Chaining runs is how you build 20–30 second AI sequences from 10-second building blocks.

A reaction that ends a beat too soon, a pan that never finishes, a punchline with no breathing room — extend the clip instead of re-recording it. Describe the natural continuation in one sentence and let the model finish the shot for you.

A 6-second product clip can become a 12-second version for placements with minimum-duration rules. Add a lingering hero shot or a slow pull-back after the action — you pay only for the seconds generated, at a price shown up front.

Treat each extension as the next story beat. Extend, review, extend again — each run takes the latest ending as its starting point, so you can steer a scene shot by shot with a fresh prompt every 4–8 seconds.

- Step 03
Step 3: Create and Chain
Hit Create. The extended video is saved to your Creations — download it, extend it again for an even longer cut, or send it into another tool.

FAQs
Grok Imagine Extend. You upload a clip, describe what happens next, and the model continues the shot from its last frame.
A tool that makes an existing video longer by generating new footage after the last frame. The AI studies your clip and your continuation prompt, then renders extra seconds that match the scene — no reshoot, no editing timeline.
Video Extend runs on Grok Imagine Extend at 10.6 credits (about $0.11) per second of generated video — the price is shown in the widget before you create. Adding 6 seconds therefore costs 64 credits (about $0.64), and credits are deducted only when you generate.
The source clip must be between 2 and 15 seconds long — the upload slot checks this before you spend credits. Clips with a clear subject and steady motion in the final second give the model the most to work with.
Between 4 and 8 seconds per generation, set with the "Extend by" control (default 6). For longer additions, run the tool again on the extended result — each pass adds another 4–8 seconds.
Yes — the prompt is required and it is your steering wheel. Describe the next moment of the scene rather than the whole video: "she smiles and walks out of frame" works better than a paragraph of setting description the clip already shows.
Text to Video creates a clip from scratch and tops out around 10 seconds per run. Video Extend continues footage you already have — real or AI-generated — preserving its exact look. The two chain naturally: generate the base with Text to Video, then extend it past the duration cap here.
The model conditions on the end of your clip, so subject, lighting and motion usually carry over cleanly. Abrupt cuts, heavy motion blur or a scene change in the final frames make continuity harder — trim the clip so it ends on a stable moment for the best joins.
There is no resolution setting. The extended clip keeps the shape of your source clip and comes out at up to 720p, so start from the best version you have. To go higher, run the result through Video Upscaler.
Every result is stored in your Creations library. Download the file, share it, extend it again, or chain it into another tool — upscale it or restyle it with Video to Video.
You can open the tool and add your files without signing in. When you press Generate, Wandura asks you to sign in or create an account, and the generation uses credits from your plan.
Both plans do. Basic is $15/month with 1,500 credits and Growth is $49/month with 6,000 credits, billed monthly; Growth adds priority support. Credit packs top up a plan and are valid for 90 days.
The credit cost depends on the model and the settings you pick, such as duration, resolution, audio or the number of results. The composer updates the price as you change settings and shows it before you create (1 credit = $0.01).
