[greg janza] "hardware acceleration for H264 rendering has been turned on. This is a huge development for those of us who export everything from rough cut to final delivery in H264. On my system, H264 renders are now 70% faster."

I'd be interested in what H264 codec you were using, what hardware and what operating system.

I just tested the new Premiere 14.2.0 vs an older 2019 version 13.1.5 on playback smoothness and export performance to single-pass 4k H264. I could see no difference. This was a 10-core Vega 64 iMac Pro on Catalina 10.15.4. Media was UHD 4k 29.97 Sony XAVC-S which is 100 mbps 8-bit 4:2:0 H.264.

Premiere's H264 encode performance had already been greatly improved around late 2018. At least on the iMac Pro I don't see any further improvement with ver. 14.2.0. Playback performance at 1/4 resolution remains quite laggy, esp. response time to JKL commands. FCPX and Resolve are much more responsive on the same hardware.

However Premiere's H264 export performance is quite good and equals or beats FCPX on the same Mac hardware. But that is not new -- it was that way last year.

I think the new improvements are mainly targeted at platforms with certain versions of nVidia's NVDEC/NVENC hardware acceleration, which is similar to Quick Sync. Supposedly Adobe says similar improvements were made to support AMD's UVD/VCE hardware, but I don't know if that is Windows only, or what versions of AMD and nVidia hardware are required.

The updated Premiere Pro handles ProRes RAW and is very fast on that.
