# Kling Video O1 Video To Video Reference

**Node type:** `video:kling_video_o1_video_to_video_reference`  
**Category:** `video`  
**Hidden in sidebar:** yes (auto-selected by routing)

## Description

Kling O1 video-to-video restyling guided by a reference

## Pricing

- **Cost:** ~27 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_o1_reference`
- **Is primary:** no
- **All variants:** `video:kling_video_o1_reference_to_video`, `video:kling_video_o1_video_to_video_reference`
