New Nvidia 20xx cards give improved NVENC quality & Open cl speed

Former user wrote on 9/19/2018, 7:26 PM

The reviews so far demonstrate the improvement over GTX10xx NVENC video quality. The following is from Nvidia:

Turing GPUs also ship with an enhanced NVENC encoder unit that adds support for H.265 (HEVC) 8K encode at 30 fps. The new NVENC encoder provides up to 25% bitrate savings for HEVC and up to 15% bitrate savings for H.264. Turing’s new NVDEC decoder has also been updated to support decoding of HEVC YUV444 10/12b HDR at 30 fps, H.264 8K, and VP9 10/12b HDR. Turing improves encoding quality compared to prior generation Pascal GPUs and compared to software encoders.

Figure 13 shows that on common Twitch and YouTube streaming settings, Turing’s video encoder exceeds the quality of the x264 software-based encoder using the fast encode settings, with dramatically lower CPU utilization. 4K streaming is too heavy a workload for encoding on typical CPU setups, but Turing’s encoder makes 4K streaming possible.

Open CL performance is also greatly improved, which as I understand is relevant to vegas due to GPU accelerated plugins only able to use open CL.

@Former user Do you have a link to this info?

The support for HEVC encoding will become more important in future. We need that.

I don't know about that. there is this new codec Av1 that almost everybody agreed on in the industry. that would maybe mean a more shorter life to HEVC in the future than we could think of... Don't really know what will happen.. (Hardware... so with accelerated encoding / decoding).

Interesting. If you encode something for HDR footage, then you use the HEVC encoder in Vegas and other NLEs. At least at the moment. To bring in metadata for HDR takes place also in the HEVC encoder only. We have no AV1 implementation up to now.

However, as someone who has started to test the HDR workflow in Vegas Pro 16, based on log footage of my EVA1 but also FS7, I can state that this works - the HEVC footage plays back in a fine way on my HDR Sony TV.

Off course, as every time with emerging technological change there are different opinions about HDR. Up to you what you think about the development of that in future.

Has anyone tested how well this works with either VP 15 or 16? This is a good candidate for me so far if there is a noticeable upgrade in performance compared to the 1080 Ti.

Hi Bunch; it's been a long time!

As I might be totally not up-to-date, please tell me:

- how is VP 16 doing regarding RTX 2080ti new acceleration?

- what's your workflow of HDR HEVC encoding using Vegas?

Thanks

Piotr

Hello again Piotr,

I have been following your hardware thread in the Resolve forum so I know you are looking at a new system. For Vegas 16, you are a little early; the dust needs to settle a bit. Vegas 16 and due another patch soon, which hopefully will resolve some issues. Graphics card choice is complicated for Vegas because of HDR support and 10 bit monitor output for workstation class cards only. More 10 bit monitoring options may be on the way soon.

PS XML export for resolve roundtrip currently does not work, but may be fixed soon.

I did a Nvenc test comparison (Gtx 1080 vs Rtx 2080) using Wwaag's free app ... VP16, 4K, 135/100 Mbps h264.

It showed a % improvement of 7.89%, for my test data. 

This only refers to the quality difference.

my question will be: Will VP be able to use these glorious resources? Would this affect timeline playback performance or rendering only? I've got a 1060/6 in there which gets barely touched unless I use some 3rd party plugins that use it...

VEGAS uses QSV for Decode Acceleration, and NVENC and VCE only for Encoding to certain formats.
