Kling 4.0 is best for long, directed shots up to 30 seconds with audio, and for keeping subjects consistent from reference images. ### How is Kling 4.0 different from Kling 3 Pro? Kling 4.0 runs up to 30 seconds at 720p or 1080p and takes up to 10 reference images. Kling 3 Pro runs up to 15 seconds at 1080p with subject elements. ### Can Kling 4.0 animate an image? Yes. Video Lab supports a starting image, first-to-last-frame direction, or a reference pack of up to 10 images. ### Is Kling 4.0 free? No. Kling 4.0 runs on a paid monthly plan. Eligible new accounts get one free Topic Short, which is a separate studio from Video Lab. Every monthly plan opens every Video Lab model, including Kling 4.0, and every generation is quoted before you generate. ### How much does Kling 4.0 cost? Kling 4.0 uses the monthly generation allowance that comes with every Clip Studio plan. Clip Pro is $19/mo ($9 for the first month if you have never subscribed). How much of the allowance a clip uses depends on its length, resolution, and audio, and the exact amount is quoted before you generate. At the default setup (5 seconds at 1080p with audio), Clip Pro’s monthly allowance covers about 5 Kling 4.0 clips, roughly 25 seconds of video, if you spend it all on Kling 4.0. A different length or resolution changes that number, and Studio Elite and Studio Scale have larger allowances. Plan details live on the pricing page. ### How do I try Kling 4.0 online? Open Video Lab at /video-lab?model=kling-4 with Kling 4.0 already selected. Sign in, write a prompt or add a source image, set the length and format, check the quote, then generate. Generate 3–30 second shots at 720p or 1080p from text, a start image, first and last frames, or up to 10 references.
