Review on 4K Video Capture Card USB 3.0, 1080P 60fps HDMI Audio Video Capture Device - Portable Converter for Gaming, Streaming, Live Broadcasting, and Teaching by Dianne Williams

As advertised, first make sure your input settings are of a high enough resolution to output sharper and better images. I've used OBS to record videos, but it also works with Discord to share your screen. I like that an AV recorder can be connected to the headphones so my voice can be easily streamed and the voice recorded through the connectors. I also add external comments as I play. Super easy to use capture card and for the price you can't go wrong.
