# Nikon

Gyroflow plays Nikon RAW video files, but Nikon cameras don't record gyro data.

Nikon cameras don't record gyro data, so they need an [external gyro source](/app/advanced-usage/using-external-gyro-source.md), or the motion measured from the video with [Optical correction](/app/advanced-usage/input-data.md#optical-correction).

Since Gyroflow 1.7.0, Gyroflow can open Nikon's RAW video files directly: **N-RAW** (.nev) and **R3D NE** (.r3d), recorded for example by the Nikon ZR. It also reads their recording metadata, like the lens focal length and the shooting settings.

## RAW playback

Gyroflow opens **.nev** and **.r3d** files directly, so there's no need for transcoding. Like R3D files from RED cameras, they're decoded with the RED SDK, which Gyroflow downloads the first time you open such a file.

## Lens profile

The camera doesn't record the lens distortion, so you have to provide a lens profile. You can either find it in the list of community-provided lens profiles, or calibrate your lens by following [🏁 this guide](/app/getting-started/lens-calibration.md).

## Zoom lenses

The camera records the focal length of every frame, and Gyroflow follows it, so you can zoom during the shot. 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 isn't recorded in the file, so you have to set it in the Stabilization panel. Read more in [🔥 **Stabilization -> Rolling shutter correction**](/app/getting-started/basic-usage/stabilization.md#rolling-shutter-correction). It's best to save it in your lens profile.

## Exporting

Exporting these files works the same way as with RED files: Gyroflow first converts them to ProRes with *REDline* (available with the REDCINE-X installation). Read more on the [RED](/app/getting-started/supported-cameras/red.md#exporting) page.

It's recommended to use one of the [video editor plugins](/app/video-editor-plugins/general-plugin-workflow.md) instead, to keep all RAW color controls.

## Shutter speed, ND filters and motion blur

You should avoid motion blur when recording if you want to stabilize in post, 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/nikon.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.
