How to Extend AI Video
Want to know how to extend AI video—add neighboring seconds to a clip you already like? On Anyken, open the AI Video Extender tool, upload a source clip you are authorized to continue, write a short continuation prompt, and generate about +5 seconds of AI continuation (default model Seedance 2.0 on that tool). Credit cost shows before submit. Eligible accounts get starter credits; plans start from $19. This page is the SFW how-to; /video-extend is the live tool—do not treat this tutorial as a replacement for the extender. Continuation is not a lossless splice of your original frames.
Open video extendTutorial page vs tool page
| Role | URL | Use when |
|---|---|---|
| How-to (this page) | /how-to-extend-ai-video | You want steps, expectations, and prompt tips |
| Tool (extender) | video extend | You are ready to upload and run |
Keep Title/H1 on the how-to question. Keep the extender page as the product URL for “AI video extender” tool intent.
How to extend an AI video clip in Anyken
- Have a source clip Use a short clip you generated or own. If you only have a still, start on a motion pass first—extend needs a video input.
- Open the extender Go to video extend. Confirm the workbench shows upload + continuation prompt. Default model on this tool is Seedance 2.0 unless your session shows otherwise—trust the UI.
- Write a continuation prompt Describe what should happen next, not a full remake. Example: “Continue slow push-in, same lighting, subject keeps walking forward.” Avoid contradictory camera flips.
- Read credits and submit Expect about +5 seconds of continuation by default. Exact length and look depend on model options—check the estimate. This is AI continuation, not frame-perfect lossless splicing.
- Inspect endpoints Watch the join between original and new motion. If identity drifts, tighten the prompt or re-export a cleaner source before spending more credits.
Continuation prompt tips
- Speak in next-beat language: “continue…”, “keep…”, “then…”.
- Reuse the same lighting and subject identity cues from the source.
- Prefer one motion vector over a list of cuts.
- If you need a rewrite of the whole clip (keep/change instructions), use the video editor path instead of extend.
Extend vs start over from a photo
| Situation | Prefer |
|---|---|
| Clip is good; need a few more seconds | video extend (this how-to) |
| Only a still; no source video yet | a clip from the still |
| Want first & last frame endpoints | ai video first last frame |
| Want Wan-led prompt / image / frames | a clip from the still |
| Wan vs Seedance (extend default) | wan 2 7 vs seedance |
| Better motion prompt before re-run | best prompt image to video |

Frequently asked questions
How do I extend an AI video on Anyken?
Open video extend, upload your clip, write a continuation prompt, read credits, and submit. Default model on that tool is Seedance 2.0 when shown.
How long does the extender add?
About +5 seconds of continuation by default. Exact results depend on the model and options—check the workbench.
Is this a lossless splice?
No. Anyken generates continuation from your upload and prompt—it does not losslessly splice original frames.
Is this page the same as /video-extend?
No. This page is the tutorial; /video-extend is the tool. Link both; do not replace the tool URL with this how-to.
Can I extend a clip that started from a photo?
Yes—first create the clip via an ai video (steps: how to turn image into video ai), then extend. Or use first/last frames on Wan when that input fits—see a clip from the still and ai video first last frame.
Is extending free?
Eligible accounts may use starter credits. Not unlimited free. Plans from $19—pricing. Starter framing: a written motion.
