VP19 Rendering issues.

Brandon-Hoover wrote on 1/4/2023, 7:22 PM

I have Vegas Pro 19.0, and I recently did a new build. Got a 7950x and 7900xtx, and I've ran into a couple issues. A side issue is it doesn't seem like rendering is using any of my 7900xtx GPU to assist in rendering, which is another topic for another day.
My main issue is CPU usage is in the 4-10% range, which is taking what would be about a 10 hour project, in 20+ hours. I have no idea why it's not utilizing CPU to any reasonable level.

There's too many variables here and too little information. Certain Fx are not well optimized and can slow the CPU to a crawl while they complete. Or this hardware doesn't yet work well in Vegas, who knows.

I'd start by trying a known good sample project and see what kind of render times and performance you get. You can see much more detailed performance reports in Windows not on the processes tab but the performance tab. Please come back with screenshots of the performance tab and the render time.

This one is during.

And this is the end

This is absolutely insane for the level of hardware present.

It doesn't matter what format I use, or what render settings, none of them are getting any proper utilization.

Reyfox wrote on 1/11/2023, 7:42 AM

did you follow the instructions? Did you post the required information in the sample project? Have you compared with others who have posted there?

I recently upgraded my much overused RX480 8GB with a RX 6700XT. I got a 3x improvement in the sample project.

Specifically, what are you expecting to see?

The reply to Roger is the sample project, with the projects sample render settings. It has a screenshot of during, and in the end.

It is literally unexplainable how bad this software is acting in conjunction with this hardware. 2 minutes and 12 seconds with a 1-2% CPU usage. There are hardware configurations considerably worse beating me.

Once again, this is a 7950x and 7900xtx, the highest end AMD hardware for consumers.

You need to look at the results again (and thank you for your upload!) You're row 65.

Your system is the only one to date to be able to preview that difficult part of the timeline at the full 25fps.
Your system is the fastest time for a UHD render, period. (You can go to data/ filter views to only see UHD results)

You reported 0:53 for a UHD VCE render, that's correct?

Congratulations on the great score! You might experiment with dynamic ram preview- see if the default of 5% speeds things up any (and if it introduces any artifacts like black frames with VCE).

I'm pretty sure that's what I saw, but in the screenshot I replied to you with on this thread, and the many times I've ran it since, its 2+ minutes. Currently running it, 16% done at 1 minutes 40 seconds.

There is something very wrong here. In the screenshots here on this thread, you can see how long it took to do the first little but on the in progress screenshot, but how fast the back 70% or so got done. Longest time yet.

I'm just going by what you submitted. Are you seeing a lot of variability between renders? For me it's within 1 second.

Try restarting Windows and do another run?

I do agree if you're over 2 minutes something is quite wrong.

The project should be slow at first and slow in the back half- it's the nature of the Fx that are used along the timeline. One of the toughest sections is the one highlighted with markers for playback. No system is normally able to play it back at full speed.

I've restarted countless times. It's so bad on my file that I did a full windows reinstall and had to download all drivers and main programs again, no better. My per thread chart on task manager looks like this, with this next to no

CPU usage.

RogerS wrote on 1/11/2023, 9:58 AM

The CPU use itself isn't necessarily an issue as this is a project that really pushes the GPU to move things around and you are also using GPU encoding (VCE).

One thing that's interesting is I see 2 AMD devices here- one is an integrated GPU? Just for testing purposes can you disable it in device manager, restart and try a render (I assume the monitor is plugged into the other card).

Can you also try a Mainconcept render (not VCE) and see what your time is and what the CPU load is like?

@Brandon-Hoover You seem to be breaking new ground with that Ryzen 7950x with an Amd igpu. Not to mention the 7900xtx which I understand is an evolution of the 6000-series gpu. I get good performance from Amd 22.11.2 drivers on a 6900xt but don't know if that applies to you. I generally select the gpu in vidoeo prefs and an igpu or 2nd gpu in i/o. Might not apply to you either. I'd suggest you try every permutation and see what works.

Btw, I wouldn't necessarily call low cpu utilization a bad thing. I go by the render time which tends to be optimal when each device in the chain is doing what it does best. If it's taking 2+ minutes to render Sample Project udh after having seen 53 seconds, maybe Vegas settings have gotten scrambled... that's happened to me on occasion and got fixed after I did a control-shift Vegas reset on startup.

And this here is the problem, after a bunch of clicks, I get it back to normal. Averaging about 4 minutes per % of completion. Then it slows down and CPU cores stop getting utilized. Then the last shows that next % is 40+ minutes.

This is just a waste of time when it drops off like that for no apparent reason.

After clicking and changing so many different things, one included disabling iGPU my project got back to the render speed I expect. The problem then becomes it dies off for no reason. This is just clips plugged in sped up 2.5x, no effects, and it goes from about 1% per 4 minutes, to over 40 minutes per %, which is so absurd there's no point in continuing this.

1st is what should happen, with speeds that reflect my computers hardware level, then at some point it dips down, and the last shows roughly how long it takes to get one more %. Just hit 68% at 6 hours 51 seconds.

RogerS wrote on 1/12/2023, 1:09 AM

Did you try Howard's suggested driver, playing with decoder settings in preferences/ file io, doing a Mainconcept render or disabling the iGPU entirely?

For this stick to the sample project as I have no idea what your real project is and higher and lower CPU loads for a project is entirely normal depending on what is going on in the project.

Brandon-Hoover wrote on 1/12/2023, 4:27 AM

I can't get very far just sticking with sample, as I've beat both 4k and 1080p record on the excel sheet, and I still clearly have a problem. I turned off and on all these settings, disabled iGPU per your earlier idea in device manager.

Then I start my render, and with earlier screen clips show it's getting proper time, with 4 minutes per %, then showed where it's started to take around 40X per minute for the SAME files, still with no effects or extra tracks on.

The file I'm working with is just recorded chunks thrown in, it's the same at the end, as it is the start. The problem is that is just simply stops using the compute power present. It simply isn't scratching the capability of what I have for the entire duration.

The current FPS counter is quite clearly bugged, as it's stayed in the same relative range as the start, but the average is tanking, and what was going to be about 6.5 hours, is gonna turn into 30 hours. It's not using my hardware as shown my screen snips, and that's in line with the amount of watts the system is pulling, as the xtx pulls 100 idle overclocked like it is.

It's really important to reduce variables for troubleshooting.

As Howard said you're a pioneer, using hardware that isn't yet really tested in Vegas. AMD drivers are also a variable. Avoid non WHQL versions.

If the sample project is rendering okay and doing it consistently then my guess is there's an issue with the media you are using in your project.

Please share MediaInfo for that: https://www.vegascreativesoftware.info/us/forum/faq-how-to-post-mediainfo-and-vegas-pro-file-properties--104561/

Please also share a screenshot of preferences/ file io in Vegas. From your CPU usage I'm guessing maybe it's HEVC and you have legacy HEVC checked? Try unchecking it and see if that makes any difference.
