V12 crashing while rendering

So... I decided I would benefit from the new color match tool along with the new masking tools of V12 on a project.

It all looked good... I was rendering to the Main Concept AVCHD templates and no problems.

Then I switched to rendering to MPEG2 (for DVD) and I get crashes after a few minutes of timeline rendering.

My work-around is to create dozens of regions and do a batch-render to NTSC DV (this format still crashed if I tried to render the whole timeline). For some parts of my project I have to render the timeline in 1 minute chunks.

So.. this is obviously not related to specific parts of the timeline.. but more to do with the way the rendering is being done and some cumulative build-up of some bug/issue.

I'm almost done with this render now.. but it's not left me with a warm fuzzy about this stuff.

Not sure if the issue is with color match - or with complex key-framing of a mask.

Anyone else have the same experience?

I sure have. My system crashes when rendering an HDV project (1440x1080) to an .mpeg2 or .avi file at 720x480 widescreen. I did an AVCHD project (1920x1080) and it rendered to 720x480 .mpeg2 with no problems. For me, it always happens when going from HDV to 720x480 widescreen (16x9).
If I go into Options/Preferences/Video and then turn OFF GPU Acceleration of video processing, then I can do the render without crashing. Since 720x480 files render faster, I guess that will due until Sony fixes the problem. I can turn it on to render Blu-Ray files.
I am using an ATI Radeon HD6870 GPU.

So... I had disabled GPU - and the crashing still happened.

As long as I split the render in to multiple regions (no more than 2 minutes in length) - I can render the entire project.

I found a couple of additional DEAL BREAKERS for using V12.

I am using the new Masking tool to do some "magic" replacement of some objects in view that the client didn't want to see in the final video. It requires a bit of key-framing on the mask. Beneath the mask layer is an image of some flooring that shows up in the masked hole and that looks pretty clean while previewing the project.

On the top layer I have a static graphic on to which I have a simple rectangular mask that shows just this graphic on the left/right of the screen - with the video below appearing in the middle portion.

Now the problems

1). After the rendering - this graphic overlay now has severe "jaggies" (like HUGE jagged edges) along what should be a pretty smooth curve in the image. I tried everything to get this to render correctly within V12. It renders OK to AVCHD... but not when I am going to DV AVI or MXF

2). The masking below this graphic appears to interfere with the graphic itself. At various points in the video some of the top graphic colors appears as blurred and moving pixels inside the area that is being masked. To my understanding the static graphic and it's simple mask should have NO impact on the mask below it. It's job is just to sit there and display whatever is the result of all the work in the lower layers.

My work-around was to switch off this top graphic layer. Render the whole project again in small chunks to that MXF format... then create a V11 project where I drag all that rendered video... and place the graphic with it's simple mask back on the top track of this project (I can copy/paste the graphic from V12 to my V11 timeline)

Then I render that to my final MPEG2 format for DVDA.

The V11 render does not introduce the "jaggies" in that top graphic and my project now looks clean and ready for the client review. PHEW!!!

So... I'm sharing this to at least provide some warning to others - that there are some very severe issues you may encounter if you use the new masking tools in V12.... and... I have no idea what caused the "jaggies" in that graphic... but watch out for that. I'll try and upload some images to show you what was happening later on.

I too have had numerous crashes rendering DVDs from the timeline on two HD projects. Vegas 12 crashes at random points on the same project, sometimes a few minutes in, but other times 30 minutes or so into rendering to DVD. Extremely frustrating. What is a little odd is that the same projects successfully produce BluRay discs rendered and burned from the timeline.

The only way I got DVDs burned was to use DVD Architect 5.2 to burn them, re-rendering from an HD rendered file from the projects. I am now wondering whether the free upgrade to DVD Architect 6.0 will have similar new bugs?!!!

I am a bit annoyed that I was asked to pay for this version of Vegas 12 as an upgrade. I don't find the extras very helpful to me. I just want stability, which I had got with version 11. Why couldn't it have been incremental upgrade of 11?
