Verdict

AVerMedia Streamer Ultra

5 / 10 Expert Rating

A plausible budget pick for live-commerce streamers who don't need more than 4K30 capture, but it's untested by independent reviewers and clearly the junior sibling to the GC535.

Blackmagic Design DeckLink Mini Recorder 4K

8 / 10 Expert Rating

An excellent low-profile SDI/HDMI capture card for DaVinci Resolve editors, entirely wrong for gaming capture.
