 Nageru currently needs:
 
- - An Intel processor with Intel Quick Sync, or otherwise some hardware
-   H.264 encoder exposed through VA-API. Note that you can use VA-API over
-   DRM instead of X11, to use a non-Intel GPU for rendering but still use
-   Quick Sync (Nageru does this automatically for you if needed).
-
- - Two or more Blackmagic USB3 or PCI cards, either HDMI or SDI.
+ - Some sort of video capture cards; typically two or more Blackmagic USB3
+   or PCI cards, either HDMI or SDI (V4L2 is not generally supported).
    The PCI cards need Blackmagic's own drivers installed. The USB3 cards
-   are driven through the “bmusb” driver, using libusb-1.0. If you want
-   zerocopy USB, you need libusb 1.0.21 or newer, as well as a recent
-   kernel (4.6.0 or newer). Zerocopy USB helps not only for performance,
-   but also for stability. You need at least version 0.7.4.
