And much more importantly, 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.

[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.

I'm running a custom built PC. I have an i7-6900k CPU and a GTX970 that I'll be upgrading to an RTX2060 later this week. My media is on nvme so my thru put is 2600/MB/sec read and 1800/MB/sec write.

I've tested the hardware acceleration on a variety of media - sony mxf 4k, xavc, etc. I see equal speed gains on every type but I also transcode all media to cineform before editing.

If you're working from H264 4k media you won't see any improvement. Transcode all H264 media to an edit friendly codec and any lag issues should disappear.

Here's a clarifying document from Adobe:

I tried it using some 4k ProRes RAW test material from a Sony FS5 and Ninja Inferno. It works well and seems very fast. That is on a 10-core Vega 64 iMac Pro running Catalina 10.15.4. I tried a few basic effects and it seemed OK but this was a very cursory test. The Premiere version number is 14.2.0 (build 47).

Speaking of a huge improvement, DaVinci Resolve Studio 16.2.2.012 just added 10-bit HEVC encode acceleration on Mac platforms. This results in approximately 25x performance increase, at least on my iMac Pro.

When exporting 10-bit HEVC from Premiere 14.2.0, the dialog says "software only" but it's much faster than FCPX. Resolve is now much faster than both of them on 10-bit HEVC encoding.

Time to encode a 17.5 sec 4k H264 timeline to 10-bit HEVC, all on 10-core Vega 64 iMac Pro running Catalina 10.15.4:

FCPX 10.4.8: Over 5 minutes
Premiere Pro 14.2.0: 34 seconds
Resolve 16.2.2.012: 12.4 seconds (was formerly slower than FCPX)
