A walking subject
The person continues walking slowly along the path. Keep the same outfit and warm afternoon light. Follow at the existing camera height with a steady movement.

Clouds over the mountains
5.0s original + 6s ≈ 11.0s complete video
Watch clouds move across a sunlit mountain landscape, then continue into the next six seconds. Review the transition near the end of the original clip. The source has no audio track; the complete result includes one.

View source exampleWhat does an AI video extender do?
An AI video extender generates new footage after the end of an existing video. It uses your source clip and a written direction to propose the next movement, camera position, and scene details. This gives a shot more room to finish: a subject can keep walking, a camera can complete a gentle pan, or a product reveal can settle before the cut. The continuation is generated content, so review the join before using it in a finished edit.
| Source video | 2–15 seconds; MP4; up to 50 MB |
|---|---|
| Added duration | 6 seconds per generation |
| Complete result | Original clip + continuation; about 8–21 seconds total |
| Output | MP4; original aspect ratio; up to 720p |
| Access | Account and sufficient paid credits |
This tool extends video duration. It does not expand the frame, change a portrait clip into a landscape composition, or recover footage that was never recorded. Your original scene is the starting point; a focused continuation usually gives the model a clearer direction than a completely new setting.
How to extend video with AI
The AI video extender works in your browser. Prepare one short, playable shot and decide how you want its ending to develop. You can inspect a local preview before signing in; uploading and generating use your account.
- 01
Upload a short clip
Choose a 2–15 second MP4 within 50 MB. Check that the final moment shows the subject clearly and that the clip plays correctly. Trim a longer recording in your editor first. The workbench displays the source duration and the expected total after the six-second extension.
- 02
Describe the next action
Write what should happen next, using one main action and a camera direction. Mention details that should remain consistent, such as the room, lighting, or clothing. Keep the prompt aligned with the final movement in the source rather than requesting several unrelated scene changes.
- 03
Generate, review, and download
Check the displayed paid-credit cost, then start the extension. Keep the task link to reopen its progress. When the complete MP4 is ready, play across the join, check the sound and subject, and download it. Your result is also available from your account history.
For example, an 8-second source becomes approximately 14 seconds. The AI video extender adds six seconds to the timeline; six seconds is not the total length of the download. Frame rates and encoding can cause small timing differences.
Prompt ideas for the next six seconds
Use these as starting points for your own footage. They are writing examples, not recorded outputs or guaranteed results. The best prompt for an AI video extender explains a small, visible change that follows naturally from the existing shot.
A landscape pan
Continue the slow camera pan to the right across the lake. Keep the horizon level and the distant mountains in view. The water moves gently under the same soft light.
A product close-up
Continue the subtle orbit around the product on the table. Preserve the background and lighting. Ease the camera movement to a gentle stop while keeping the product centered.
Video extension, looping, or slow motion?
Choose the method that fits your edit. An AI video extender is useful when the story needs new motion after the last frame. A conventional editor is often the better choice when you only need a repeated background, an exact pause, or a change in playback speed.
| Method | What changes | Use it for |
|---|---|---|
| AI video extension | Generates new frames after the existing clip | Continuing a gesture, camera move, or scene ending |
| Looping | Repeats frames already in the source | Repeating textures or a deliberate repeating motion |
| Slow motion | Plays the same event over a longer interval | Slowing an action without inventing its next moment |
| Frame expansion | Adds or reframes image area around a shot | Changing composition; not provided by this tool |
Help the AI video extender keep your scene coherent
Video continuation is a creative prediction. It can follow useful visual cues, but it cannot promise identical faces, precise lettering, physical accuracy, or an invisible transition on every clip. Make the input easier to interpret and leave time to review the result.
- End on a readable moment. A stable subject and clear direction of motion give the continuation a useful starting point. Sudden cuts, heavy blur, or a subject leaving the frame make the next action more ambiguous.
- Keep one continuous shot. Ask for a modest continuation of the current action. Multiple characters, fast collisions, rapid camera changes, and intricate hand movements introduce more details that may drift.
- Check the connection point. Watch the last moments of the original and the first moments of the extension together. Compare clothing, lighting, object positions, and camera direction before placing the clip in an edit.
- Listen as well as watch. Audio behavior depends on the source and the generated result. If dialogue, music timing, or a particular sound must be exact, plan to finish that part in an audio or video editor.
Clear credit costs before you extend a video
The AI video extender is a paid generation tool. Each run uses the paid credits shown beside the generate button. The same six-second extension is used for every accepted input length. Gift and check-in credits do not fund this model; review your eligible balance and choose a credit pack or subscription if needed.
If a generation fails technically, its charged credits are returned. A completed result may still differ from your creative intent; that is not the same as a failed task. Review the source and prompt before starting another paid generation. Download and watermark access follow your account entitlements.
View credit plansAI video extender questions
How many seconds can I add to a video?
This AI video extender adds six seconds per generation. Accepted sources are 2–15 seconds long, so the complete result is approximately 8–21 seconds. A single run does not turn a short clip into a minute-long video. Only videos within the input limit can be submitted for another extension.
Which video files can I upload?
Upload an MP4 file up to 50 MB with a duration of 2–15 seconds. Supported codecs are H.264, H.265, and AV1. Browser preview support varies by device; an H.264 MP4 is a practical choice if your original will not play locally. Convert other formats before uploading.
Does the download include my original clip?
Yes. The AI video extender returns the original clip followed by the generated continuation as one MP4. It keeps the source aspect ratio, with output up to 720p. It does not promise a byte-for-byte copy of the original encoding or an upgrade to 1080p or 4K.
Can I use the AI video extender with audio?
You can submit a supported clip that contains audio, but sound in the complete result should be checked after generation. Exact dialogue continuation, uninterrupted music, and matching lip movement are not guaranteed. Use your editor to adjust or replace the soundtrack when timing matters.
Is there an AI video extender with no login here?
You can read the guide and preview a local video without logging in. Sign-in is required to upload, spend paid credits, and generate. Your account connects the job to its progress, result, and history so you can return to it later.
Does this offer no censorship or unrestricted generation?
No. This AI video extender follows the website terms and the model provider’s content rules. Only upload content you own or have permission to use. A paid account does not remove content restrictions or guarantee that every prompt will be accepted.
What happens if generation fails?
A task marked as failed returns the credits charged for that generation. Upload or input errors can be corrected before a task starts. If a request loses its connection, keep the page and retry the same submission; the tool retains its request identity to avoid creating the same task twice.
Will the extended scene look exactly the same?
The AI video extender aims to continue the visible scene, but faces, small objects, text, motion, and lighting can change. A short, clear source and a restrained prompt improve the guidance you provide. Review the result for your intended use before sharing or publishing it.
