Having some issue with Vegas Pro 15 That I cant work out -

I am having issues with Vegas Pro 15 that have semi started out of the blue.

Ever since I have been using it it regularly hangs and crashes - these seem common problems that show up on many google searches and I was able to work around them and as long as I saved often it didnt really affect my work flow too much - besides a lot of frustration and about 50 reports to Magix via the crash log thing that pops up.

However yesterday I was using the software to make a video - I chose to make the preview full screen which happened however the image on the screen was frozen - I couldnt get it back to normal with escape.

I could bring up task manager and alt tab to select other things running however the full screen was always in front.

I figured it was another crash and software bug so I selected to restart the computer which it did - now this is where my real problems have started.

When the computer restarted I got the Error 59 Bug which I worked aroudn eventually I had to reinstall 15 pro to fully get around that.

Now Vegas 15 starts ok you can use it just as normal but I am having an issue rendering as I was before.

Using the GPU render option as I have been successfully for months the video I am creating gets to 25 - 35% and hangs and either the preview window flashes with some odd frames - Or it goes white with some other part of the video overlaid onto it.

Or it goes white and the overlaid video is upside the down like the preview window has rotated 180 degrees

I have tried all the obvious fixes - reset the software, disable SO4, Video preview to 0mb - to be honest I had done all these anyway to try and get better stability.

I am trying a CPU render now to see if its any better and just hoping for the best as I need to get work out but I am pretty peeved that this software is so buggy and I am having so many issues after spending hundreds of pounds on it.

My PC is modern powerful with loads of ram and a good GPU so there is no issue there, Its also not hot in the slightest.

I am hoping someone can advise me here - I really dont want to have to try an OS Reinstall as its a lot of work because its my work computer and downtime is bad for me

Thanks in advance - really appreciate any and all help

The error 59 was fixed with a new installation of the software.

However the registration process didnt seem to work and I had to keep doing it every time I started Vegas again

Another installation of Vegas fixed that issue.

I did try third time lucky and installed Vegas again but not joy on the gpu rendering problem

I thought things mere miraculously fixed - I changed a HD for a larger one - 3TB to 8TB - I used the 8TB as the source for the media and another 4TB as the drive to render to.

The video got to 74% before it crashed same as usual - talk about a tease.

So then I tried a render with GPU disabled and the pc seemed to be acting strange there was nearly the full 32GB of ram being used.

A restart - the same project rendering now using 11GB of ram. That's how much the software is messing around for me

@Pursuit-Perfect-System sorry if that has already been covered, but can you share what kind FX and Plugins you are using in that project? Are all native to Vegas?

Pursuit-Perfect-System wrote on 4/30/2018, 1:24 PM

only some basic ones - native brightness contrast, Luts and Sharpness - nothing external.

That is my concern 4-5 hours for a render like this cpu only will be 20 once I start using Denoise or Mercalli or the one that stops led light flicker - forget the name now

VP15's build in LUTS FX or VisionColor? And you mentioned this is a 8bit project? Did you monitor disk activity too?

I was using Vison colour but realised recently they make renders slow as hell so moved over to the native Luts option in VP15 and rendering times reduced by about 10x.

I havent monitored drive activity no - however I can run a test now rendering to my OS SSD from my new 8TB Barracuda Pro to rule out the Other HD which is a WD Black I think

Could it be too slow now its 85% full? Surely it would slow the project down not cause it to crash.

It renders fine to that drive using CPU Only GPU disabled

Thanks for trying to help

85% is rather full and if the drive is fragmented, it can cause problems.

I will run the test as mentioned - if thats a fix then happy days.

I thought I would update this thread - Magix support had me trying all sorts and nothing fixed my problem.

I posted today in the new 361 Build thread and one of the developers contacted me personally try a fix.

This is the fix

If you hold down the shift button can going into the preferences dialog, there is a tab called "Internal". Go to that tab. In the bottom of the dialog there is a text box. Type "Enable OpenCL/GL Interop". Set the value of this setting to "FALSE" and restart VEGAS. Then do your render again

I actually dont believe it - my problem is fixed at last - with a really simple settings change - I knew it had to be something.

There is a slight trade off - the cpu is working harder than normal but only about 80% with gpu working a little less at approx 10%

However an approx 8 hour render on CPU only is down to 3 hours like this so I am not complaining and am happy to be not leaving a render running all night every night.

Thanks very much to the Magix Developer for contacting me personally with this fix I am extremely grateful to you. So grateful in fact!!! Thank you

That's cool you got help after all that. Just for my own info, what does OpenCL/GL Interop do exactly? Why was that the culprit?
