I followed a youtube tutorial and was able to adjust a preset template from 1980 HD to 2160 4K and successfully rendered an mp4 file after a few tries.

Why, VMS16 has already a 2160/4k preset template?

e, but each time I try I get the "an invalid argument was specified" error message.

HOW CAN THIS BE? Please Help.

Because you have changed some settings in the rendertemplate.
If you do what @3POINT is telling you and use a default 2160 4 K template that message should not be possible.
F.i. one of these

The .mov selection to make a movie carries the 4K dimensions, but didn't work with 5.1 surround sound. There is no preset for 4K and mp4 that I discovered in VMS16. I used the 1920 x 1080 preset and made adjustments from the youtube tutorial,

I can see that these presets will render 4K video. HOWEVER, I am editing with 5.1 surround sound and they only support stereo sound. There is not adjustment you can make to in the AUDIO tab to switch from stereo to 5.1 surround sound. So THAT is the real problem. Rendering in 4K with 5.1 surround sound.

I did it once successfully and my query to this group asked How This was Possible, not how to render 4k.

The YTvideo shows changing a rendertemplate in Sony VegasMovieStudio13 also without 5.1 surround. We're now in VMS16, were that rendertemplate is already implemented.

If have no experience with surround audio. The only rendertemplates i know that can do surround is Sony AVC, but that goes only to FHD.

As mentioned in a previous post there are rendertemplates in VMS16 for 4K. But they do not allow for 5.1 surround sound. (I haven't found any, if you know of one, post it here). My question is about some kind of cache file or software glitch as I have successfully rendered 4k with 5.1 surround sound ONCE, but now get the error message when trying to render it again from the same project. I thank you for your posts. But I have already researched the render capabilities for VMS16 with 4K and 5.1 surround. I need help with the software cache problem.

@Antony have you tried a new project, get 4K 5.1 render and then the same error on subsequent renders? In otherwords can you duplicate the problem with a new project?

What template would you choose?
I 'm not finding any 4K template in VMS or Pro that can do that.
The only ones I can find are FHD Sony AVC or HD WMV, not 4K, so help me!

Eagle Six:

I just created a short new 4K 5.1 surround sound project and followed the same path to render it as mentioned in the youtube tutorial for version 13 of Movie Studio. I got the error message the FIRST time. It did not render as was the case in my original project.

I followed the instructions on this youtube tutorial:

If you look the right way when the render options were changed the audio still remains Stereo and thats also the new rendertemplates will do. Faster than the older versions but still not in 4K surround, it stays in stereo
You also did not ask in your OP to render surround. You only wanted your project render to 4K video and that did we answer with the new possibilities in VMS 16 Pl.
What you want you can try only to render your 4K video seperated from the audio and your audio also seperated to a surround audiofile and stich them together in one or another program, that I not know because I will never search for it, because with the modern audio players attached to my TV I don't need it.

Thanks for your posts on this matter. As you read in my original post I successfully rendered a 4K mp4 file with 5.1 surround sound. If you don't believe me I have the file to prove it. I posted my query not for a discussion on 4K and stereo vs surround sound, I posted to ask if anyone could tell me why my render worked once, but now fails.

Eagle 6 gets it. You don't.

Have a good day.

That video file you once rendered to 4k 5.1 – which type is the audio of this file? Is it AC3 or AAC? Could you check via MediaInfo?

No problem for me because I don't have any problem with the program. 😊
But I'm very curious about the file you rendered once with the settings you wanted, but that was not following the tutorial you showed because if you did you would get a stereo mp4 like I show you here in that tutorial.

You can place the link of that file(or a part of it) of VMS 13, I'm very curious about, uploaded to an website like dropbox or so.

I just see what works for rendering 3240 x 2160 with 5.1 audio is WMV. In the WMV render settings just switch the audio type to "Windows Media Audio 10 Professional" to get the 5.1 options.

There's no such option for MP4 output, though, and it's never been there, not even for Vegas Pro.

Hey j-v:

If you look to the bottom of the requester you see the Audio tab. When you click on that there is a pull down menu that defaults to Stereo, but has a 5.1 surround option. That's what I did, changed it from stereo to surround.

But even though I changed the video aspect ratio to 3840 by 2160 when the mp4 file rendered it had correct 5.1 surround sound, but defaulted to the 1920 x 1080 aspect ratio which I didn't notice until now. So that 4K mp4 file with 5.1 surround sound is really only an HD file.

Hey Marco:

Thanks for the post. You asked about the audio. When I checked the details for the mp4 file it was listed as AAC and to my surprise the aspect ratio was 1920 x 1080! Ooops. Looks like I never rendered 4K after all! I swear I changed the parameters to 3840 x 2160 and when I watched on my 65" Vizio 4K smart TV I thought the images were 4K. Well, there you go. Seems I can get 5.1 on mp4 as HD, but not on 4K.

In Platinum 16 I can manipulate and edit with 4K video files and export as 4K with several options, but none of the options include 5.1 surround sound.

So any ideas on what software supports editing 4K with 5.1 surround sound that you can export to mp4?

but defaulted to the 1920 x 1080 aspect ratio which I didn't notice until now. So that 4K mp4 file with 5.1 surround sound is really only an HD file.

😁👍
And that is exactly the reason ( you did not see the difference), why I since a few years don't need to render to 4K when that export file is only for my 4K TV, with, I think, a very good upscale option.

So to summarise;

Question - How can you export 4K video with 5.1 Audio to a mp4 file with Vegas Movie Studio 16 Platinum?

Answer - It doesn't appear that you can at present.
