What is being recorded?

Video

We record the output source of the routed output (by default set to Engine).

If there is no level launched, an empty file is being recorded.

To record the input, pass it through the LVL_VideoPassThrough level.

Tracking (optional)

If enabled, we record the tracking data of the active camera.

For compatibility reasons is the tracking information embedded inside the audio channel. This data sounds like loud noise when listened to in a video player.
