Hi, is there something provided within that link that corrects the problem above? Most of what was being said went way above my head unfortunately.

Is Sony XAVC a good alternative for 4k gameplay rendering? I might have to try that one out next if I can't find a fix for the above issue.

Certainly better than hardware encoding.

Seems that Sony XAVC rendered it correctly at least :). File size was gb's larger than I anticipated but nothing my upload speed can't handle. If another render ever glitches out I know where to turn to. I have rendered 3 more videos since and not one of them had that odd glitch.

Have you tried to set DRAM to zero before rendering ?

This is a sample example of rendering errors.
The solution is to leave the DRAM at any number (eg 2000) and change only the number rendering threads to 1.

Method:
1. Permanently set number rendering threads to 1
2: DRAM for example 2000
3. Restar Vegas

4. Render your project

It works for me, without artifacts and errors in the video.
Do not use Magix AVC - it is of poor quality. Much better is the Sony AVC.

Sometimes updating your GPU driver, especially changing to the studio drivers for nvidia cards if you haven't already, can help this.

The link you were given is to a Vegas extension called happy otter scripts. you can sign up for its beta, then download it for free (at least while it is still in beta testing). HOS has a sub-program called Render + that allows you to utilize ffmpeg encoding within Vegas, as well as other cool tools like noise reduction, free. The x264 encoders it uses are of the highest quality for the format, and they typically do not suffer from the repeat frame stutters the Vegas GPU encoders have.

I just tried that but that particular video still glitches post render.

I will just change to a different render codec going forward. When you say Sony AVC did you mean the XAVC? Sony AVC doesn't seem to have a customizable profile for 4k just custom framerate with a locked maximum bitrate which is set pretty low in comparison with some of the others.

I might download that then thank you for the explanation :)

I used the Nvencoder to begin with at 4k, 60fps, 100k bitrate but whenever I play it back post render there are two 5s or so glitches 

"100k bitrate" is obviously a typo. If that is actually 100Mbps, try cutting that in half and see if it makes a difference.

That actually fixed it using the Magix AVC profile. What's odd though is in the recording the bitrate details display 128445kbps yet rendering it caused glitches with high bitrates. I will set this as the solution but I might go ahead and render using a different template going forward.
