# Z CAM

Z CAM Mark II cameras record motion data and lens metadata internally.

Since Gyroflow 1.7.0, Z CAM Mark II cameras are supported. They record the motion data, the lens focal length and the frame readout time in the video file.

## Supported formats

* **MP4** and **MOV** files play in Gyroflow, and the motion data is read from the same file.
* **ZRAW** (.zraw) - Gyroflow can't play these files, but it can read their motion data. Open a playable copy of the clip (e.g. a transcode or a proxy) as the video, and then load the original **.zraw** file in **Motion data -> Open file**.

## Lens profile

Gyroflow creates the lens profile from the focal length and the sensor area recorded by the camera. That lens profile has no lens distortion, so it works well for rectilinear lenses with little distortion. For wide or fisheye lenses, load a calibrated lens profile instead, or calibrate your lens by following [🏁 this guide](/app/getting-started/lens-calibration.md).

If your lens doesn't report its focal length to the camera (e.g. a manual lens), you also have to provide a lens profile.

## Zoom lenses

The camera records the focal length of every frame, so Gyroflow follows the zoom automatically. If you want to smooth out fast zooms, enable **Stabilize focal length** in the Stabilization panel. Learn more in [🔭 **Advanced usage -> Lens profiles**](/app/advanced-usage/lens-profiles.md#zoom-lenses).

## Rolling shutter correction

The frame readout time is read from the file, so you don't need to set it.

## Shutter speed, ND filters and motion blur

You should avoid motion blur when recording, read more why in the [📸 **Common filming tips and issues**](/app/getting-started/common-filming-tips-and-issues.md).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.gyroflow.xyz/app/getting-started/supported-cameras/zcam.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
