Missing video

Hi everyone, I need your help.

We're running an event with a pre-recording of an interview which was recorded over Zoom. The interviewer switched the recording to pin the interviewee, and now the entire interview is solely of the interviewee - which will be pretty boring viewing for an event. 

Does anyone know if there's a way to retrieve the interviewer's video feed? 

Thanks in advance for any suggestions - all ideas welcome!

Nikki
