Vegas Pro 19 - Nvidia Render fps jumping

VVV wrote on 4/27/2022, 2:09 AM

Hello :)

Straight to the point, when I do render with a constant bitrate, and I have some indicators in the render window that behave strangely, namely: "Current speed", goes up to 120 frames, then goes down to 0 - and I don't understand why, disk usage no more than 20%, cpu usage is the same... I have more than enough ram, as well as bread oven body (= pc) pieces, they are good in terms of gaming performance: 5800x, 3060ti (497.29 - because the February update was causing crashes in one game), 32gb, 750w, win10 pro latest updates, vegas pro 19 550

I feel like I need some simple advice - "how to set up vegas 19", please tell me what I can do to solve this

ps. render and project settings are pretty correct, I believe

It's a Vegas bug that affects MagixAVC, and probably MagixHEVC when using NVENC for encoding. It pauses every 60 frames.

In a single test recently I found this caused a slow down of 13% at 4K, 0.0% slow down at 1080P, and 43% slow down at 720P. 1080P not having any slowdown is strange so needs further testing as the pause was still very obvious.

The gauge of how much slowness was caused by the pausing was made by comparing it to Voukoder NVENC encodes which don't have the pause.

@VVV Hi, you can upload video & pics on here using the arrow button next to the smiley at the top of a new comment, not everyone wants to click on a link 👍 (don't know about Gifs, - just tried it & apparently not - 'Error: The selected format is not supported ' - so you'd have render as MP4 or something else)

Also Hi, can you go to your icon at the top, click it - My Profile, & fill in your Signature with your Vegas version, Windows version & system specs, full name of CPU, GPU, & amount of RAM etc. this will then show at the bottom of the comments & will help people help you 👍 (see mine & other peoples at the bottom of comments) thanks.

@Former user thank you for reply

(I don't understand why such a big company with a complex product can't fully implement the basic functions, which is why it is necessary to use a third-party rendering library @vegasCollective)

such a big company

@VVV Vegas is definitely a Tiny Company. It definitely has fewer employees than your family members.

I believe you are experiencing normal buffering. Possibly some non-accelerated stuff on your timeline.

@walter-i. @Musicvid If the 60frame pause was normal it should be seen with VCE and QSV encodes via MagixAVC but it's not, and the encodes are faster due to there being no pause. This is what created the myth that AMD and Intel hardware encoders were faster. The encoders are slower, but in Vegas they're faster due to the 60fps pause bug. People then went on to extrapolate based on hardware encoding figures that the GPU processing was also much faster on AMD GPU`s

Seems to be typical for using NVENC rendering with Vegas. I don't experience this "buffering" when using QSV rendering with Vegas. (Also I don't experience this "buffering" using NVENC rendering with Resolve).

My internal iGPU renders much quicker with Vegas than my expensive NVGPU.

re: I guess I found the render problem, all the time I was using 32 full levels for my project props, because on default 8 picture is grey in preview, but ONLY in preview; amazing

Try rendering with Voukoder for Vegas. It will render faster, better and without jumping (when NVENC supported) than Magix (when NVENC supported).

Yeah, I saw this method, but with 32 bits it always took a long time to live with

And it always jumping does not matter if you using Veg or Vou render..

So I fact checked you,

MagixAVC pauses, Voukoder doesn't. 32bit processing , 4K60 project, 4K60 encode, encoding Nvenc

Voukoder was 14% faster due to the lack of pausing.

What you showed in that GIf, is a bug specific to MagixAVC/HEVC using Nvenc, so why claim it exists in Voukoder?

Voukoder loads the GPU evenly- if you don't see that maybe you have a bigger bottleneck elsewhere.

And the worst thing is that these MagixAVC/HEVC NVENC encoding pausing are afterwards visible in the renderresult. You will see pulsating artifacts in detailed parts with same colour.

VoukoderAVC/HEVC NVENC encodings are faster and look much better.

3Point: really? I never saw such phenomen in V19.
Voukoder is faster also by me, but only a few percentage, i think because the lack of pauses.
Quality is nice, better in general at the same bitrate compared to Magix nvenc hevc, but i found a scene where Magix was better visually at the same bitrate. Main benefit to me is, that Voukoder doesn't need 3x the free space than the rendered while, and dont do muxing at the end of process. Write the final file from the start, right?
Can anybody confirm? I have to test this soon.

Never saw such artifacts myself. It just renders in batches of frames.
