Generate controlled AI videos with keyframes and references



Kling 4.0 is an artificial intelligence video generation model developed by Kling AI, available through this independent studio web application. It transforms written concepts and still media into moving footage. The system addresses common generative video challenges such as erratic movement, visual drifting, and short clip limits by allowing users to guide scene transitions and character consistency.
Instead of relying entirely on text prompts to determine how a clip unfolds, Kling 4.0 introduces deep reference controls. Users can supply beginning and ending frames, multiple mid-scene milestones, or reference collections of imagery and motion clips to direct the generation path.
The platform supports extended video generation ranging from 3 to 30 seconds. With adjustable frame framing, multiple resolution choices, and multi-asset guidance, it gives creators granular control over visual storytelling without requiring complex local hardware setups.
Kling 4.0 serves creators and teams that need visual consistency and directed pacing in AI-generated footage:
Marketers can develop short commercial drafts. By supplying a product still as a reference, a team can test different commercial backdrops and visual treatments before booking an expensive live studio shoot.
Video creators can produce serial vertical shorts. Setting start and end frames guarantees that visual assets remain cohesive across dynamic camera pans, preventing the morphing artifacts common in standard text-only video tools.
Educators and trainers can build visual explainers. Turning abstract explanations into continuous 30-second instructional clips helps viewers follow technical procedures and concepts clearly.
Kling 4.0 operates on a paid, non-subscription credit model where purchased credits never expire. The Starter pack provides 260 credits for $9.90 ($0.038 per credit). The Creator pack costs $29.90 for 960 credits ($0.031 per credit). The Studio pack offers 2,000 credits for $49.90 ($0.025 per credit), and the Business pack costs $99.90 for 5,000 credits ($0.020 per credit). For Kling 4.0 Text to Video, generation consumes 5 credits per second at 720p (25 credits for 5 seconds) and 8 credits per second at 1080p (40 credits for 5 seconds). A 7-day refund window is available if no more than 10% of purchased credits have been consumed.
Do credits expire or require a monthly subscription?
No. Credits are bought through one-time credit packs with no recurring subscription, and purchased balances never expire.
What input files can be used with Omni Reference?
The studio accepts up to 10 reference images and up to 5 reference videos totaling 30 seconds, with a combined limit of 15 reference files.
Can I generate 4K video directly in this web studio?
The underlying Kling 4.0 model supports up to 4K resolution, but the web generator studio currently provides 720p and 1080p outputs.
Can Keyframes and Omni Reference modes be combined?
No. You must choose between Text to Video, Keyframes, or Omni Reference for each generation task.
