Hello.
There is a way to obtain availability of "hardware encoding" with 8th gen Intel CPU?

I'll better explain.

I've a Nvidia GT1030 (without NVENC) on a Z370 with 8th gen Intel i5 8400 (that has UHD630 QuickSync GPU).

GT1030 doesn't have any HW encoder.
UHD630 (the GPU within the i5) has QuickSync, that I use with Handbrake, for instance.

QuickSync is a VERY fast way to encode in Handbrake, compared to the CPU.

Why, when I choice "GT1030" in "performance", I've the checkbox "Use hardware encoder" availability even if GPU doesn't have NVENC?
Obviously, if I try to encode, it doesn't works.

And why, when I choice "UHD630" in "performance", I've not same checkbox availability?
UHD630 doesn't suitable for this?

I'm confused about this.
Does Vmix use ONLY NVENC or other engines, like QuickSync.

An AMD RX GPU will works?
And what about a Ryzen 2400G (with Vega GPU)?

Thanks for attention.

Not sure about the QuickSync encoder in the CPU. Will be interesting to see how admin replied.

The encoder in the AMD GPU is definitely not supported.

If QuickSync is not supported, I would suggest replacing the GPU with one that offers NVENC.

It's my last chance, but QuickSync it's a VERY GOOD and cheapest encoder.

When VMIX will supports FFMPEG3-4 maybe it works.

You can use QSV externally of vMix. I agree it's fast and very low on resources.

Just use EXTERNAL out to feed your own encoder with QSV support (for example FFMPEG or OBS)

I've a little fps loss when I import 60fps Vmix video to OBS.

Better adopt FFMPEG3 (we are on FFMPEG4).
