Review on 🎥 Mirabox USB3.0 4K HDMI Video Capture Card: Capture and Stream in 1080P 60FPS for Xbox, PS5, Switch, DSLR - Perfect for OBS, Twitch Live Streaming and Recording by Dewitt Bhattacharya

This card is a decent mid-range streaming/recording card. It actually streams 4K which is important for console/TV streaming and I checked the 1080p60 output. The quality is acceptable for most 1080p streams, most people won't notice any difference, but for a high quality setting this mjpeg compression can be problematic. USB 3.0 speed cannot be tested. I measured the latency below on a Win10 i7-6XXX system with a stopwatch with microsecond precision, the monitor running at 60Hz. 5, standard deviation = 3.3): avg: 65ms, avg: 65ms, low: 62ms, High: 70ms. Capture latency with Directshow over FFmpeg (n=10, SD=40.8): Average: 143.6 ms, Medium: 125 ms, Low: 61 ms, High: 194 ms
