# Runway Act-Two

Directed dialogue shots and short character performances

- **Availability**: available
- **Where it runs**: hosted
- **Costs**: October 2026: 5 credits per second. The web guide lists a 3-second minimum; API credits cost $0.01 each, making the API rate $0.05 per second. Budget for repeat takes.
- **Adult content policy**: restricted

Act-Two suits a character cutscene where delivery matters: you record the timing, expression and movement, then transfer that performance to a character reference. A still image allows gesture transfer; a character video keeps its existing body and camera motion while Act-Two changes the facial performance. Rehearse and approve the driving footage first, then review the result for identity and gesture drift. The output is rendered video, so keep the shot separate from the game’s reusable rig, collision and skeletal animation. Clear the rights to both inputs before uploading.

## Commercial use & license

Proprietary hosted model governed by Runway’s service terms and your access plan. No downloadable weight license is listed for this route.

## Adult content rules

Runway prohibits adult nudity and sexually explicit content on its hosted services. It may also restrict sexually suggestive imagery, including lingerie.

[Read the policy](https://runway.com/safety/usage-policy)

## What you need

For API use, select act_two with a Runway developer project, API key and funded credits. The web app requires Standard or higher. Supply a driving performance video and a character image or video. Use one subject with a visible face, waist-up framing and an uninterrupted take. Gesture transfer requires a character image; character videos retain their own body and camera motion. The web guide lists clips up to 30 seconds.

Ranks are recommendations for the task described, based on reviewed documentation. Model ranks cover non-explicit development work. We have not run practical benchmarks. Check content policies and commercial terms separately. [How the ranks work](https://bestadultgames.io/en/developers/methodology.md)

## Why consider it

- Uses recorded delivery and expression to guide a character shot
- Transfers hand and body gestures with a character image
- Retains camera and body motion from a character video

## Tradeoffs to plan for

- Driving footage requires permission and appropriate rights
- Delivers video without an editable character rig
- Identity and gesture consistency need review

The tier reflects documented fit for the workflow described here and availability. No numeric score or hands-on performance results are provided.
