Video Duration Options

Video Duration Guide

Choose the right video length for your content needs. Duration directly impacts both your video's impact and credit cost.

Available Durations by Model

Different models support different duration options:

Kling 3 Pro offers the widest range — from 3 to 15 seconds — making it the most flexible option for any content length.

How Duration Affects Cost

Video cost is calculated per second:

Formula: Duration x 5 credits x Model Multiplier

Example costs for Kling 2.6 Pro (2x multiplier):

• 5 seconds: 5 x 5 x 2 = 50 credits

• 10 seconds: 10 x 5 x 2 = 100 credits

Example costs for Kling 3 Pro (2x multiplier):

• 5 seconds: 5 x 5 x 2 = 50 credits

• 10 seconds: 10 x 5 x 2 = 100 credits

• 15 seconds: 15 x 5 x 2 = 150 credits

Example costs for Veo 3.1 (5x multiplier):

• 4 seconds: 4 x 5 x 5 = 100 credits

• 8 seconds: 8 x 5 x 5 = 200 credits

Note: If you select a higher resolution (on supported models), the cost is multiplied further — 2x for 1080p, 3x for 4K. Audio generation also adds to the cost where supported.
