Record only Video from the speaking person in HD despite shared screen

[frank_k]

I have tested the recording function at Zoom (for enterprises) and found out how the HD recording works. However, I still have one problem: As soon as a presentation, screen, etc. is shared in the webinar, the speaker video is automatically in small sized in the recording because the shared screen is then automatically displayed in large size. However, for a later video editing, I would like to record only the speaker with the best possible resolution, but not the shared screen. How can I solve this problem?
