Render Crash – Unmanaged Exception (0xc0000005)

[Phil Ingleby] ” but it’s always down to the “mc_enc_avc_ocl.dll”.”

That is the Mainconcept OpenCL GPU encoder. In the render as template you are using it is still trying to use GPU for the encoder. Set that to CPU only.

There are two GPU settings. One for Vegas itself and one for the file encoder.

Thanks for the reply!

I set the render encoding to CPU only but unfortunately I’m getting the same crash but with “mc_enc_avc.dll” as the culprit instead. The crash also happened a lot sooner than when I render with OpenCL, if that’s any help.

UPDATE: So I tried rendering the same project as .avi and it worked without a crash with OpenCL enabled. I did notice that rendering .MP4 causes my CPU usage on all 4 cores to go to 100% load and spike my temperatures to 100c, where as .avi it stayed below 50% with relativity cool temps. I didn’t notice any difference in the rendering speed either.

Could this be an issue with there being too much load on my CPU and my temps causing the render to halt?

[Phil Ingleby] ” go to 100% load and spike my temperatures to 100″

Yes, It does sounds like you were getting an unstable CPU due to overheating. You need to clean/dust and/or fix/upgrade your CPU cooler.

You AVI render sounds like you were rendering to Sony YUV.

[Phil Ingleby]

Yep, after I took the side of my case off my temps lowered by about 30c and the video rendered normally!

Thanks for all your help. 🙂
