# ExifTool

[Exiftool](https://exiftool.org/) is a command line tool, much like FFMPEG, but it’s strength over FFMPEG is metadata. I started using it years ago because I needed to pull lens information off of some video files. Premiere doesn’t tell you what the focal length is of a video file, but Exiftool does.

### ExifTool Cheat Sheet

To get all metadata of a file

```
exiftool file.mp4
```

To update the metadata so that it says that it’s 360° spherical VR (this is so you can preview VR in VLC!)

```
exiftool -XMP-GSpherical:Spherical="true" file.mp4
```
