Kling 4.0 takes a clip to 30 seconds and lets you pin the first and last frame or feed it ten reference stills; Kling 3.0 Omni stops at 15 seconds but offers 4K and seven cast faces, and is the cheaper per second. Long staged shots go to 4.0, short 4K close-ups go to 3.0.

What 1,000 credits buy
1,000 credits is $4.00. At the cheapest listed rate that is about 28 seconds at 720p on Kling 4.0 and about 56 seconds at 720p on Kling 3.0; at the dearest listed rate, about 18 seconds at 1080p and about 11 seconds at 4k. The Lite plan's 800 credits a month are four fifths of that.
A brief written for each
The studio's scene writer works in timed beats with a camera plan and an audio line, and these two briefs are shaped the same way. Paste either into Mint Studio with the model chosen and the price appears on the button.
Kling 4.0
A 24-second single take, 0–24 s: from the first frame (a closed shop door at night) the camera pushes through the door, glides past the counter and ends on the last frame, the owner turning the sign to OPEN at dawn. CAMERA: one continuous dolly. 1080p.
Kling 3.0
A 10-second close-up: the shop owner @Ana leans on the counter and says "Best bread in town, since 1962" at 6 s. CAMERA: slow push-in on her face. 4K with native audio: the line, a kettle, street noise.
