I needed a good quality monitor and HQ video recorder to operate with my Blackmagic ATEM mini extreme so that, principally, I could record myself at my weekly Zoom meetings, and if I needed to absent myself from the meeting for a short while, I could seamlessly playback the recording of myself (via this unit through the ATEM) without any of the attendees realising that I was not there in person! It was then very easy to switch back to live when I returned. I did try a much cheaper alternate version of this type of unit before purchasing the Blackmagic Design Video Assist, but that cheaper item just did not compare in any way at all. The Blackmagic Design Video Assist however, just does the job perfectly. Highly reccomended.
