Key features
Kling V4 Reference turns reference images into video inside Enhance AI. It produces clips from 3 to 30 seconds at 720p or 1080p. On top of that it renders auto, 16:9, 9:16, 1:1 and 21:9 and it accepts up to 10 reference images. Kling V4 Reference is built by Kuaishou. On Enhance AI it runs on the same account as every other model, with no separate subscription.
Clip length
Kling V4 Reference renders clips from 3 to 30 seconds, and you pick the length before you render. Longer clips cost more because video is billed by length, so rough out an idea short and only render the full length once the shot works.
Resolution
Choose 720p or 1080p before you render. A lower resolution costs less, so test a prompt low and rerender the keeper at the top setting. The studio shows the price for the setting you picked before anything is charged.
Input modes
Kling V4 Reference takes a written prompt, reference images (optional), reference videos (optional) and reference audio (optional). Add them in the studio, check the preview and render. Every output lands in your history, ready to download or to pass to another model on the same account.
Reference images
Add up to 10 reference images and Kling V4 Reference holds a character, a product or a style steady across shots: the gap between a clip that looks like your brand and one that looks like the model's idea of it. Attach them next to the prompt.
Aspect ratios
Kling V4 Reference renders auto, 16:9, 9:16, 1:1 and 21:9. Pick the ratio for the platform before you render rather than cropping afterwards: 9:16 for Reels and Shorts, 16:9 for YouTube, 1:1 for feeds and 21:9 for cinema. The whole frame is generated for that shape.
Audio
Kling V4 Reference can generate sound with the picture, so the clip arrives with audio that matches what is on screen rather than silence you have to fill later. You can still mute it and lay your own voice or music track over the top in any editor.
