Interesting that you complain about AMD performance and list an nvidia video adapter.

How about my Ryzen 3900X

That isn't a GPU. GPU decode and rendering support is what was added. Vegas has always supported AMD CPUs. I'm using it now with a Ryzen 7 1800x. The fastest Vegas render speeds ever posted on this forum used AMD Threadripper CPUs.

Your issues likely stem from a driver issue with your nvidia GPU. Try updating your driver to the latest STUDIO driver from Nvidia (not game ready).

Then why isn't it working w/o GPU? Just to make it clear, I have been using Vegas for years but always with an Intel mobo. Obviously Vegas has problems with the AMD Ryzen 3900x because v16 has similar but not as severe problems. I am using the latest drivers...

I too am having this problem, and have submitted a support ticket. I have an AMD Ryzen 9 3900X 12 core processor @ 3.8 GHZ (which does not have HDMI graphics), but I had an old i7 Intel on an Asus motherboard with built-it Intel graphics, and while not perfect, it was far more stable than Ryzon. (And of course about 40% slower).

I have an NVDIA GeFORCE GTX 1070 card, but tried GeFORCE RTX2080 Super and a Radeon 5700XT cards, same problem. I have all the latest drivers (yes the STUDIO driver for the NVIDIA). I spent two days with a reputable repair shop making sure everything was up to date. We even tried using older drivers.

I mix a lot of 4k multicamera live concerts, but also do lo-res webinars and 1080p docs, and the problem is the same no matter what the source material.

Is there anyone out there who uses Vegas and it does not crash? What are your system specs?

I have a Ryzen 3900X with a Radeon Vll running vegas with no problems.

Have you tried the latest AMD chipset drivers? Latest version is 2.03.12.0657. Does Windows crash when Vegas stops? Did you uninstall Vegas completely, then reinstall? Is BIOS up to date? I know the shop said everything is up to date and did they tell you it is a Vegas problem? What motherboard are you using? How much memory?

When you uninstall you video card drivers did you use DDU? Then reinstall latest studio drivers? DDU is free to use, and very easy to use.

What version of Windows are you running. Fully updated?

1. I would uninstall Vegas. 2. I then would update Windows. 3.Then Install the AMD chipset driver restart system. 4. Then run DDU in safe mode to uninstall video drivers make sure you have checked in DDU options do not let Windows update driver. 5. Then install latest NVIDIA studio driver restart. 6. Then reinstall Vegas.

I use a program called Revo uninstaller it searches the registry when I uninstall a program and cleans the registry along with the program. It leaves no traces of any program you decide to uninstall.

Ask, and ye' shall receive!

Check my signature. I use Vegas Pro 17 (Edit - Bld. #421). My computer specs are in signature.

Does Vegas Pro crash? Occasionally. So does Vegas Movie Studio Platinum 16 (Bld. # 175). But, with the funky-a$$ drivers AMD puts out for their GPU's, this computer has crashed more when clicking on a tab for YouTube videos. More so than either of the Vegas products!

Oh, on an older MSI X99A Gaming 7 with i7-6800K running Vegas Pro Suite 15 (Bld. #416), using Gigabyte GTX 1080 Windforce 3 OC, 32 GB DDR-4 3200 Mhz, doing fine. Guess what? The machine crashes, rarely with Vegas Pro, but crashes more when playing Mass Effect Trilogy.

And of course, my last machine with a 2920X on Asus X399 ROG Strix, RTX 2070 Founder's Edition, 64 GB RAM and only Vegas Movie Studio Platinum 16 (175), runs fine too.

Biggest thing? Don't use the screwed up "Microsoft Downloadable" drivers, get them from the manufacturer's site. Plus, if you are using AMD newer chipsets (AM4, X399, TRX40), you also need to go to AMD's site and download the updated chipset driver.

Yeah, all three machines running Windows 10 Pro 64-Bit (1909), all with the latest Windows updates. Both computers running Vegas Pro also have the Happy Otter Scripts by wwag (1.0.2.71 - have not installed the 1.0.2.72 yet).

Also, NO OVERCLOCKING! And, all three machines on Air Cooling. And, unlike the stupid gaming trend of "no one needs an external 5 1/4 Bay", or "cram all that into a small, air restrictive case", mine actually all have external bays, with Blu-Ray burners, and LOTS OF VENTILATION!

Oh, the majority of my video is from a Sony FDR AX-33, Sony FDR AX-53, GoPro Hero 5 Black, GoPro Hero 6 Black, (2) GoPro Hero 7 Blacks' - all recording in 3840 x 2160 @ 30 or 60 fps, with the Sony's using the 100 Mbps 4K XAVC-s. Poor lonely Canon 80D can only do 1080, but I use the .mov ALL-I for the higher bit rate. All the machines handle the footage fine, whether H.264 or H.265 - just use either Proxy files, or transcode to AVI via Happy Otter Scripts - depending on what I am doing.

Does that answer your request, sufficiently?

Just to be sure, in my case Vegas does not stop or crash. The rendered mp4 file is the problem. Rendering runs w/o any problem. With GPU faster than w/o but that's it. But the resulting mp4 file stutters and stops. Sometimes after just 3 or 4seconds, sometimes later. Then the video does not show anything for several seconds before showing the rest of the video. Sometimes it is smooth before and after the stop (v16 w/o GPU); the worst case with a lot of stutter and a long interruption is with v17 plus GPU.

Again, there is no indication while running Vegas that the rendered result will have these issues.

Driver issues are likely the culprit as others have mentioned.... However, search the Internet & you will find a TON of folks complaining on various forums about AMD 3900X overheating issues... Also, certain motherboards are not as stable as others when powering the 3900X or 3950X... Download several stress test apps & see how your system runs them 24/7. I've been building my own editing workstations for over 20 years.... I find the CPU clock speed my system runs a stress test 24/7 and then slow it down one notch. My current 9900K will run 24/7 at 5.0 ghz, so I slowed it down to 4.9 ghz. All is stable with an Intel CPU & AMD VEGA 64 GPU. IMO Vegas runs better on Intel CPUs & AMD GPUs than the reverse...

Harold what rendering template are you using? Are you changing any settings when you render out? Try to render with a different mp4 templete see what happens.

Is it the same event giving you the problem? Try another event and render that see what happens.

I agree with therhino could be driver issue. See my post above.

Chief try the pro drivers for your Radeon VII. I was having crashes also with the 20 series Radeon drivers just by playing 4k videos from my Sony AX 700. I installed the newest pro drivers have not had 1 crash. I have not yet tried a full project yet with vegas, but have put 6 minutes or so of 4k events on time line previewed and render out to different formats with no problems.

I did notice when I rendered out that my Radeon was using most of the memory on the card and the clock speed hardly was used. I forgot what template I was using. I was using gpuz to monitor.

Actually did try the "New" pro driver the day after it was released. Did not see any difference in performance, for my work, but changed back to the WHQL 20.2.2 because that version is what is recommended for the Happy Otter Scripts that I use (based on the requirements put out by wwag). They've been pretty "steady" so far, and like I mentioned, have had more crashes when clicking on the "New Tab" for YouTube while watching videos, than from Vegas Products. I really do like the Radeon VII card, and it is a Beast for Vegas Pro and Movie Studio, sort of like the Frontier Edition that BruceUSA uses.

I do not "Overclock" anymore since retiring, but do know the pros and cons. Like TheRhino above who has that i9-9900K "Smoking" for his work, he also found the "Sweet spot" and backed-off a tad, which so many people out there won't, then complain about their systems, or like this or the Magix forum - "The crappy software". I frequent the Magix forum as well since I have Audio Studio, Xara Graphics, and Music Maker, and see all the same type of complaints, with unfortunately so many of the Moderators who try to help, being excoriated by the masses, with most of the problems brought on them by themselves. Therefore, some of my "Replies" in the forums are a bit Blunt. Never one to back away from the Bullies.

But, aside from that, having fun with my systems. That "elderly" X99 system is starting to act up more frequently now, so looking at how I want to upgrade that one. Who knows, maybe I'll try and go back to the "Main Stream" platform again!?

If people would look at the "Minimum Requirements" for software, then plan their build, along with their finances, around those requirements, then go a notch or so above on the hardware side, even if having to wait one more pay-day, they would probably see fewer issues. See the same with all the Gamers out there trying to run the newest AAA title on close to 10 Year Old hardware. Ain't happening! Best example (or phrase I should say): "But, can it run Crysis?"

Not stressing my system at all

I tried different templates and files. Same results. The weird thing in my opinion: after the 1st stoppage the remainder of the rendered video looks just fine with the exception of stutter with v17.

By the way, the difference in behavior between v16 and v17 directly points to an issue pertaining to Vegas and not to my drivers. Obviously Vegas has a significant problem with the AMD 3900X. If I had know beforehand I most likely would created an Intel system again instead of switching to an AMD base. Too late now. I, and many others can only hope that Magix addresses and fixes that problem very soon,

I tried several Vegas supplied rendering settings and some work, some don't. E.g.

Sony XAVC 1920 x 1080 29.97 worked like a charm,

Sony AVC Internet 1920 x 1080-30p did not. The high quality worked, the lower one did not.

MAGIX AVC Internet 1080p 29.97 (NVIDIA NVENC) did not,

but w/o (NVIDIA NVENC) Internet 1080p both 29.97 and 59.95 did work.

The MAGIX NVIDIA drivers all stopped at around 32 seconds for 13 secs whereas the Sony stopped at around 19 secs for 7 seconds.

By the way, the difference in behavior between v16 and v17 directly points to an issue pertaining to Vegas and not to my drivers. 

No, it doesn't, or others (like Sassylola) using the same CPU here would have the same issues. There's an underlying cause you're missing.

Great, so it is all my fault. You intentionally overlook the others that have the same problem. With support like that...

I just rendered a 3 minute clip of 4K videos taken with my Sony AX 700 shot at 29.97 with text and jpeg overlays and a MP3 file. I rendered with The Sony AVC Internet 29.97 and Magix AVC Internet 1080P 29.97. Both played back in Vegas and VLC player with no problems. For the Magix AVC I used the AMD VCE mode as I have a AMD GPU.

@harald 

1) “It stutters and stops rendering mp4 files“

2) “The rendered mp4 file is the problem. Rendering runs w/o any problem.”

So which is it? Is it a rendering issue within vegas pro? or is it that the rendered output file has playback issues? or is it both?

Item 1) is a known issue when using HW encoding, nvenc, it renders very fast, pauses, then picks up again, but completes the rendered files aok, just appears a bit odd.

If its 2) then you need to supply mediainfo screenshots of your render template that gives item 2) plus mediainfo screenshot of your source file.

Ideally supply a downloadable sample file that others may render out with your chosen render template that causes the problem.

I misspoke initially, i.e. it is not 1). The rendered file stops and stutters.

You obviously decided to ignore my responses afterwards where I made clear what my problem is. That it works for you is great for you. It works for many others as well; great. But I and also others have the same problem I described. You seem to conclude and insist that I have a set-up problem. My set-up is just so basic that it should work every time: string 3 simple mp4 files together and add some text. NOTHING else. No need for mediainfo or screenshots. That has worked for me for years and now it doesn't for SOME of the rendering settings I described. I.e. I am limited in my selections, at least for the time being.
