Hardware Encoding Unavailable at High Settings Premiere Pro 2020

Question

Hello, I recently have started using Adobe Premiere Pro 2020 and I have run into a problem with encoding. I wish to use my Hardware Encoder when I encode, but when I try to select my hardware encoder, premiere says "Your system's hardware does not support hardware acceleration for the current settings". I am trying to render at 4K, 240mbps, 60 fps, at maximum render quality with VBR, 1 pass. I am also using Optical Flow for my time interpolation.

I know for sure that I can use my GPU to render because I am able to render at the same quality in Sony Vegas Pro 17.0. I just don't know what to do. Premiere actually will in fact allow me to use Hardware Encoding but the best quality it will allow with Hardware Encoding is 1080p, 60fps, 50mbps, with optical flow. Using CBR as well.

My System Specs:

CPU: Intel Core i5-3470 (Integrated Graphics Enabled)

RAM: 20GB DDR3 @1600Mhz

GPU: PNY GTX 1050 Ti

Sony Vegas Pro 17.0 allows me to use Mainconcept HEVC, Intel Quicksync, and my NV Encoder (Hardware Encoder). I do not know why Adobe's software thinks my computer cannot handle it.

I have attached what Sony Vegas Pro 17.0 allows me to do, what I want to render with Premiere, and what it will only let me render with Hardware Encoding.

If anyone could help, I would love you forever. Thank you!

I am very sorry to tell you this, but your CPU platform is now too old for any recent version of Premiere Pro. You see, Adobe now only supports QuickSync from 6th-Generation or newer Intel Core CPUs. In fact, it now requires a 6th-Generation (Skylake) or newer generation CPU just to run properly. Your CPU is only a 3rd-Generation (Ivy Bridge) CPU. Therefore, the Compatibility Report should have flagged even the latest 3rd-Generation driver as "Unsupported."

And no official release of Premiere Pro so far officially supports anything other than Intel's QuickSync for hardware encoding. Unfortunately, Adobe's implementation of the QuickSync hardware encoder is hard-limited to a maximum of around 60 Mbps. If you try to export at 240 Mbps, QuickSync will default that bitrate to a very low fail-safe rate of about 16 Mbps.

A beta 14.2 release of Premiere Pro, which is available to Creative Cloud subscribers via the "Beta Apps" section of the Creative Cloud app, supports NVENC and VCE in addition to QuickSync. However, the non-Intel hardware encoding is still in beta at this time, so you may want to wait for a finalized release of 14.2 or similar in order to get your wish.

By the way, Vegas may technically permit you to set an encoding hardware-accelerated bitrate that high, but the finished exported video's actual file size, and therefore bitrate, is far lower than your intended setting. That is due to the limitations of current hardware encoders. The REAL bitrate of that exported file is, unfortunately, very low at about 16 Mbps.
