How to Extend a Video with AI
To extend a video with AI, upload a continuous shot, describe what follows its ending, choose a supported duration, and review the generated continuation. Here is how to prepare the clip and direct the next beat.
Do you need new footage or more screen time?
Several techniques make a clip longer, but only continuation generates a new action after the source.
Prepare the clip and settings
These are the current default requirements in LumiYing. Recheck the uploader when selecting another model.
Read the last moment before writing the prompt
The ending supplies the starting point for the new footage. A prompt works best when its instructions agree with that moment.
Name the next visible action
Replace “make it longer” with an action: the cyclist follows the bend, the camera continues pulling back, or the product completes a small turn.
Separate subject and camera
A subject moving right does not mean the camera should pan right. State both when they matter, and keep their directions consistent with the source.
Keep only the details that matter
Mention the outfit, product silhouette or lighting that must remain recognizable. Leave unrelated style changes for a separate generation.
Extend your video in four steps
Keep the source and prompt together so you can compare revisions.
Prepare the ending
Watch the last second. Remove a cut or obscured frame, then upload the continuous clip through AI Video Extender.
Write a continuation instruction
Use the displayed reference label, such as @Video1. Describe the next action, camera movement and two or three important details to retain.
Choose a short first request
Confirm video extension mode, supported duration, resolution and credit estimate. Start with the shortest duration that fits the intended action.
Inspect, download and assemble
Watch where the source hands over to the continuation, then the full result. Check motion, shapes and sound. Download the accepted output and arrange the final sequence in your editor as needed.
Worked example: finish a coastal ride
This is a planning example for a source clip, not a measured video result. The cover illustrates the intended sequence.
Three continuation prompts to adapt
Replace @Video1 with the reference label shown for your upload. Match each instruction to what actually happens in your source.
Continue an action
Continue @Video1 from its ending. The cyclist in the rust jacket follows the coastal path through the bend at the same steady pace. Keep the existing tracking direction, bicycle, outfit and late-afternoon light. One continuous shot.
Use a source that ends before the cyclist completes the bend.
Finish a camera reveal
Continue the slow pullback at the end of @Video1, revealing more of the lighthouse headland and surrounding sea. Keep the lighthouse shape, horizon and golden-hour lighting consistent. Do not cut to another angle.
Keep the direction and speed compatible with the original camera move.
Extend a product shot
Continue @Video1. The blue ceramic teapot completes a gentle turn on the display, then settles into a quiet closing shot. Retain its spout, wooden handle, proportions, tabletop and soft window light. Add no text or new objects.
Add titles and an end card later in your editor; inspect the product geometry first.

Questions about extending videos with AI
Can I extend a video that was generated by AI?
You can upload an exported clip if it meets the input requirements. Its source model does not remove the need to check duration, format, visible detail and the generated continuation.
What should the continuation prompt include?
Name the source, the action after its ending, the camera direction and the important details to retain. Avoid retelling the whole original scene as though it should begin again.
Can I extend the result again?
You can reuse a compatible exported clip as a new input. Prepare it within the upload limits and review each stage; details can drift over several generations.
Will the original audio be preserved?
Do not assume the output retains the source soundtrack unchanged. Listen to the result and keep your original audio in the editing project if exact dialogue or music timing matters.
When should I use a loop instead?
Use a loop when repeating motion is the intended effect. Use AI extension when you want new action or a camera move to continue beyond the source ending.
