# Kling Video V1 (Legacy)

**Node type:** `video:kling_video_v1_standard_text_to_video`  
**Category:** `video`  
**Hidden in sidebar:** yes (auto-selected by routing)

## Description

Auto-switches between variants based on inputs

## Pricing

- **Cost:** ~9 credits per second
- **Per-second rate:** The figure is the rate at a 5-second reference run. Our margin is progressive and steepest on the smallest runs, so a clip shorter than that can cost more per second, and a model priced with a flat multiplier is exact at every length. The charge is always computed from the real duration.

## Variant family

- **Family:** `kling-video`
- **Is primary:** yes
- **All variants:** `video:kling_video_v1_standard_text_to_video`, `video:kling_video_v1_standard_image_to_video`, `video:kling_video_v2_5_turbo_pro_image_to_video`, `video:kling_video_v2_5_turbo_standard_image_to_video`, `video:kling_video_v2_1_master_image_to_video`, `video:kling_video_v2_6_pro_image_to_video`, `video:kling_video_v2_6_pro_text_to_video`
