MXO2
"MX Oxygen"
was a Pro PCIe capture device, still good enough today for HDMI 1080p30p
has a PCIe card, but can be used with Thunderbolt2 or ExpressCard34.

there was 2 versions available...
Standard: I/O Only,
different size configuration i/o, small mini basic, medium, battery powered portable, rackmount, pcie card mojito, pcie dsp only compresshd.

MAX version = includes aditional DSP ic that allows encoding h.264 video in HW, fast, silent, and power efficient.
No need for CPU fans spinning at 2000rpm for hours.

Matrox Max Caputre h.264 SW is better for Windows8.1, 10,
Ventura Capture for OSX only works in Yosemite 10.10 or older, never updated..
but Matrox MAX v4.6 drivers work upto OSX HighSierra 10.13.6
works up to FinalCutPro 1O.4.3 + Compressor 4.4.1
Adobe CS6 Encoder Pre-Mercury Engine..
FCP+Compressor+GPU acceleration+MAX DSP+CPU does encode faster & silent.

there is also Unofficial OSX drivers Non-MAX, that support QuickTime Apps.

Official drivers for OSX v4.6 do Not support QuickTime Apps, Only direct support: Avid, Adobe, etc...
There are MAX and Non-MAX drivers.

seems there is No Linux support.
