Intel Quick Sync Video (QSV) is a technology available on some Intel processors, that provides hardware acceleration for video encoding/decoding. QSV offloads video encoding/decoding to a dedicated hardware CPU core, providing faster results and reducing the video footprint on server CPU performance.
Attention!
C-Werk applies Intel QSV for decoding:
- Remote clients.
Video formats: H.264, H.265 and H.265 +.
- Live, Archive modes (forward playback only) and TimeLapse.
To use Intel Quick Sync Video, make sure your system meets the following requirements:
Since QSV is incorporated into the graphics processor, your CPU must have one (iGPU).
Note
You can check if the CPU supports QSV here.
Attention!
For H.265 and H.265 + video, Intel Quick Sync Video technology is supported only on Intel processors with microarchitecture: Braswell (only decoding), Cherry Trail (only decoding), Skylake, Apollo Lake, Kaby, Gemini, Coffee Lake.
- The mainboard supports iGPU (includes Flexible Display Interface).
The Graphics driver supports QSV. We recommend using the latest version of the Intel HD Graphics Driver.
Note
You can also update the driver automatically using the Intel Driver Update Utility utility.
To activate the Intel QSV in C-Werk you need to:
Enable using the integrated graphics option in the BIOS settings.
Note
Depending on the BIOS version, it may be named differently (iGPU , Internal Graphics , Integrated Graphics Adapter - PEG).
- In general, the simultaneous use of the integrated graphics unit (iGPU) and external GPU has to be avoided. In this case, to use Intel QSV, do as follows:
- Enable Multi-Monitor in the BIOS settings.
Connect a “Fake/Virtual” Monitor/Display on Windows and then connect it to your iGPU and select Extend desktop to this display in the Multiple displays list.
- Go to Settings → Options → User interface (1–2).
- Select the Intel Quick Sync check box (3).
- Click Apply to save the changes.
