# 360 Video Metadata

Use the
[Spherical Video](https://github.com/google/spatial-media/blob/master/docs/spherical-video-v2-rfc.md)
standard for encoding 360 video.

## Camera Manufacturer and Model

We *strongly* recommend that you specify camera manufacturer and model in
[user-data atoms](https://mp4ra.org/#/atoms) in your MP4 360 video. We support
two ways of doing this:

- `manu`: Camera manufacturer (make)
- `modl`: Camera model

OR

- `©mak`: Camera manufacturer (make)
- `©mod`: Camera model

## Camera Firmware Version

We *strongly* recommend that you specify camera firmware version in
moov/udta/meta/ilst/FIRM as a string in your MP4 360 video.

## Verification

You can verify your video with [ffprobe](https://ffmpeg.org/ffprobe.html) command:

    $ ffprobe your_video.mp4
    ...
      Metadata:
        make            : my.camera.make
