Questions
Is Kling 4 priced on Kling’s own API page?
No. The video pricing table at kling.ai lists Kling 3.0, 3.0 Turbo, 3.0 Omni, O1, 2.6, and 2.5 Turbo. There is no Kling 4 row. A Kling 4 price is not published on their site in that table.
What Kling price can be quoted?
Kling 3.0 without native audio is $0.084 per second at 720p, $0.112 at 1080p, and $0.42 at 4K. With native audio and no voice control, 720p is $0.126 per second. These are API unit prices, not an app subscription.
How long is Kling 4?
Clip length for Kling 4 is unconfirmed. A Kling release note for 3.0 Omni says video editing supports up to 15 seconds and 4K. That note is not a Kling 4 specification.
What is the Seedance 2.5 API formula?
BytePlus LAS lists an enhanced unit price of $0.303 per second. For Seedance 2.5 with no input video, the 720p factor is 1.525 and billing uses output duration. With input video, the 720p factor is 0.9125 and billing uses input duration plus output duration.
Where does AI Video Swap fit?
We do not sell Kling or Seedance text-to-video. A face swap video here is £0 for 5 seconds at 480p, then £4.99 for 10 seconds at 720p.
