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.
LumiYingUpdated
Several techniques make a clip longer, but only continuation generates a new action after the source.
These are the current default requirements in LumiYing. Recheck the uploader when selecting another model.
The ending supplies the starting point for the new footage. A prompt works best when its instructions agree with that moment.
Replace “make it longer” with an action: the cyclist follows the bend, the camera continues pulling back, or the product completes a small turn.
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.
Mention the outfit, product silhouette or lighting that must remain recognizable. Leave unrelated style changes for a separate generation.
Keep the source and prompt together so you can compare revisions.
Upload one continuous source clip in AI Video Extender. Check the selected model’s file, duration and size requirements before generating.
Describe what happens after the uploaded clip ends. Name the next action, camera direction and details to retain, then choose the model and available duration.
Choose a supported model and duration, then review the displayed credit estimate. The current default produces 720p; available input and output limits depend on the model.
Review the returned video against the source ending. Check motion, subject details and sound, then download an accepted result and assemble your final edit as needed.
The coffee example below uses a 4-second stock source and a 5-second continuation request. Compare the actual source and generated result before adapting the prompt.
Compare a 4-second source with a separate generated continuation. Load a clip and its settings to try your own next action.
Keep the overhead coastal view moving as the next wave reaches the same shore.
Check shoreline angle, wave motion and camera drift at the join.
Continue the overhead coastal shot from its final moment. The next wave rolls onto the same shore and its foam recedes naturally. Maintain the same camera height and slow drift, shoreline direction, wet sand, water color and daylight. No cut, zoom, new objects or text.

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.
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.
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.
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.
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.
These examples return a separate continuation of about 5 seconds; the 4-second source is not automatically included. Keep your original and join the clips in your editor for a complete sequence. Check the returned footage when changing models.
Prepare one continuous shot and a short instruction describing what happens next.
