Can I record a RemoteSpark session?
At present time, there is no embedded recording functionality within RemoteSpark - but there are workarounds to record the session outside of RemoteSpark.
To record from the PC:
You can use video screen-capture software to record the screen during video calls from the PC, including from within Microsoft PowerPoint.
To record from the HoloLens:
You can also take video using Mixed Reality Capture on the HoloLens to record what the HoloLens is seeing.
