Review on ShuOne Capture Card: HDMI Game Capture for PS5, PS4, Switch with USB 3.0, 1080p 60fps HD Video, Low Latency HDMI Passthrough - Ideal for OBS, Twitch Streaming and Recording by Frank Ridl

The software documented on the device is called PotPlayer. When recording (it's the only function I've used) it would skip, freeze and generally not handle the recording well. I switched to OBS Studio (Open Broadcaster Software®️) Open Source. It does the job a lot better. OBS creates large files when writing in lossless mode, but this can be fixed with HandBrake (also open source), an encoder that reduces file size.
