Can I record myself in Video using Metronaut?

Yes!

Starting version 6.2.0 you can make Video Recordings of your performances, with yourself included (or not) via your device's Camera.

You can enter Video Mode by pressing the Record button on any music score page, and then selecting Video. While in Video mode, any performance triggered by the Play button will record the screen, the audio and your camera input.

After each practice session, your recordings will appear in "My Recordings" in the My Music tab or the My Recordings section of the piece that can be reached through the same Record button on each music sheet.
