On paper the RTX 4000 meets all the requirements or Movie Edit Pro (MEP) ie DirectX 12, OpenCL, NVENC f, however it appears that it is designed more for advanced graphics design eg architectural design, science simulations etc.
The real performance will depend on the rest of the computer specification and what you are actually using in the project in the way of effects, transitions, and for the encoding speed the actual NVENC module built in to the card - I can find no information on this, however given the target market for this card I suspect it would be no different to the the NVENC module in GPU's such as the RTX 2000 and 3000 series.
If you have a friendly computer supplier, would they let you test a RTX 4000.
Thanks, for your response, but my problem is probably bigger...Is possible to use hw acceleration for AMD processor? I have AMD Ryzen 9 3900XT and NVidia GeForce RTX 3060Ti. There is not any internal Intel HD graphic...Is there exists any alternativ process how set hw for this case?
Movie Edit Pro 2022, and Video Pro X 13, can utilise 3rd party GPU's with or without an Intel processor, the options are in the program settings as shown below - the image is from VPX 13, MEP 2022 is similar however an option is missing.
if you are not gaming on this PC, check that the drivers are up to date and you are using the Studio version these are more stable than the Gaming (GRD) drivers and are specifically designed for video/design/imaging work, the current version is 472.39 (30.0.14.7239).
If you are using MEP 2021 or earlier than the program is more limited and as you have no Intel processor the RTX 3060 should already be selected in the Program Settings, Display options tab.
