I'd stick with 4K and try to diagnose the problem.

What are your system specs?
What version of Vegas are you using?
What GPU are you using?
Please share a screenshot of your render settings.

Green screen is likely because you disabled the modern decoder. I'd set the file I/O tab to disable all legacy decoding and keep hardware decoder to auto.
For renders dynamic ram preview to 0MB for rendering might help.

Then if you are on VP 18 go to help/driver update and update GPU drivers.

If you are using 10-bit footage you'll need to switch to 32-bit video (or full if you want ACES) to get the most out of it. That will further slow down render times.

@dez123-vaghy Long discussion here re: user with A7S3. If you have VP16 try it as a temporary solution, it may be better? The next update may, very likely will, bring improved support for Xavc hevc 10-bit HEVC 420 support. The new generation of Intel Xe GPU's, to be announced soon, will bring hardware decoding of your A7s 3 footage if using 10-bit HEVC 422, maybe?

My system is as follows.

ASUS GeForce RTX 2070 Super 8G EVO Turbo Edition GDDR6

CPU Ryzen 7 3800x

Windows 10 64bit with 32 gig ram.

Vegas 18 Build 482

Willl try some tweaks as suggested above thanks.

The Ryzen is a great CPU, but at the moment Vegas relies on CPU-integrated Intel GPUs to decode some formats of video. You may have to transcode outside Vegas until a software (CPU) decoder is released.

For the RTX 2070 download the latest Studio driver (help/driver update should find it or you can go to Nvidia.com).

@dez123-vaghy Don't how how your camera is set up but according to the specs on B&H there are recording mode options: in addition to 422 options there are also h.265 420 10-bit and h.264 420 8-bit options which should be fine with Vegas. With your Ryzen system you probably need to use the h.264 mode for good edit performance. But try them both and see how it goes.

Its hopeless, now I can't even compile what I was able to do last night. I have to use my 8 bit camera until I can figure this out. Aggravated very much....

By compile, you mean render? What happened? What render template did you use (screenshot if you can).

The a7sIII can also shoot 8-bit but that shouldn't be necessary. Which media setting did you use?

You are on the NVIDIA Studio Driver?

Yes Render. It seems that ever since I enabled the ability to see 10 bit HD files, everything is going wrong. What was a stable system now freezes or the render doesn't complete. I have multiple edits to do every day and I am stressed to compile something 3 minutes long. I only have done a few changes, and reverted, and then also reverted back to 8 bit video, and am left with wondering if I have to reboot, or restart the application after it stalls after 3 minutes of rendering.

I wonder if Final cut is hard to learn. LOL I am considering it.

My drivers are up to date since a few weeks ago and the system was rock solid! No crashes or any issues for a long time. All I did was adjust Dynamic Ram Preview to 0, Maximum number of rending threads to 16 and in File IO tab uncheck "Enable Legacy AVC decoding" which let me view the Sony A7S3 HD 10 bit files. (this enabled a feature which I saw briefly) I wonder if this simple change screwed things up for me? I can't see how these changes could fuck the system up totally. Initially I was able to render 4K footage and now I can't render anything as I could a day ago which screws me for 2 projects that need changes made.

One solution for when things inexplicably stop working is to reset Vegas. You won't lose any projects or Fx or media, just custom settings. You can do this by holding down control and shift on startup until it prompts you to clear the cache (and do clear it). I'd give that a try, especially if the issues started after updating to 482.

Then keep it on defaults and see if it can render the project. I might then disable legacy HEVC decoding (which is the default).

It really shouldn't be this bad for you and none of the settings you changed are problematic. I always have legacy decoding disabled and while I don't have an sIII, have played with test 10-bit footage to get experience with it and didn't have render issues.

Thanks for the suggestion. I have done it. A reset. Edited a video and rendered no problem in 8 bit, then went back to my project with 4K XAVX HS 10bit, and during rendering it simply froze up about 23% in. had to kill Vegas and restart. Funny, I was able to render this project before enabling the option to view XAVC S HD footage. Its only after the step to enable this feature that things have started going wrong. I wish I can undo that one thing.

What are your exact settings on the XAVC HS?
https://support.d-imaging.sony.co.jp/support/ilc/hevc/01/en/index.html

Is it HEVC 10-bit 422 or 420? I'm guessing the latter if you were able to edit it at all. Is all the footage in this project the same or is there anything notable happening 23% in? Can you copy the timeline (select all, copy/paste) to a new project just in case it is a project issue?

You said your drivers are up to date but didn't confirm you had the Studio driver, not the general GeForce one. Under help/driver check does Vegas find a different driver? You can also download it from Nvidia.com.

That "one thing" is just a coincidence and isn't the cause of your problems. Resetting completely Vegas undid any changes.

HAVC HS 4K 60 frames a second, 150M 4:2:0 10 bit

I had a workaround... that didn't work. I rendered the project a bit at a time to put them together at the end. I was able to render a 2 minute section, and then going on to doing the next 2 minutes the program just froze. I think the application is running out of resources and just stalls.

Anyhow, the client will make due with current version. I'm dropping back to using the A7S2 until I can figure out what to do next. Thanks so much for everyones help.

If you can't find a fix you can also try rendering in Vegas using Voukoder. Try x264 and apply the general preset.

"The new generation of Intel Xe GPU's, to be announced ... "

Not just announced, it's here, it's available.

@Marco. I admit to a little confusion on my part re: availability of new Xe iGpu's and dedicated XE GPU'S.

I know that several, three?, laptop models have been available, in the low to middle range. for a while.

I'm not aware that any Xe GPU'S were yet available, in say PC's. I suspect you are more au fait with all of this. Glad to have any more input from you on this.

My own interest is in updating/replacing my laptop with this tech, but afaik no “Gaming” type laptops are yet available, probably this summer?

I meant particularly the Acer Swift 3x with Intel Iris Xe as iGPU and both the Xe Max as dedicated GPU (and i7-1165G7 CPU). I just didn't have the time to test with VP18 yet.

@Marco.

 "I just didn't have the time to test with VP18 yet."

No pressure there.

I'll check out those items u mentioned.

Hi guys, I have a request. I want to know if anyone knows how to revert back to before the state of unchecking the option in File I/O "Enable legacy AVC decoding"

Here is why. My observation with Vegas 18 is for a couple of months now that It has been solid for me, never crashing or stalling or anything while using it extensively. My only change, Unchecking "Enable legacy AVC decoding" which brought up a small window (can't remember what it said) enabling some service.

I only did this in the first place because I bought a Sony A7S3 to up my game in video making.

I have dropped back to the A7S2 but now I have stalls. Hanging the program mid way through a render. Not at any particular location. I find that after editing and before rendering, I have to exit the program, execute again and then perhaps it will make it through a render. I conclude that perhaps it is because Vegas is running out of resources. The CPU calms down and the render just stops.

there must be a way to disable some sort of DLL file that it is suddenly using because I was trying to use the 10bit HD files. I just want my system back, I can't stand the waste of time this is causing.

Any ideas? Thanks

Reset Vegas. There's no huge change you made so nothing to restore.

What are your export settings? Codec, renderer, settings? Can you playback the file ok on the timeline without any problems? Are you using any plugins that could cause the issue?

Hi there! Is there a way I can manage to get 10 bit files to work with VP 15?
For a project I shot with the A7S3 in XAVC-S-I HD, in 4:2:2 10 bit, and this turns out as a green screen in VP15.

Is there a way to fix this or am I really going to have to buy VP18?

Any help would be very much appreciated!!!

Thank you!!!
