Christian/Blink,

I see now that you can actually turn the paging file off - even though MS "strongly recommends that you do not disable the paging file". Blink, that's how you run?

My paging file size is set to 5GB at the moment. Vegas 8.0c cannot render AVCHD files for me without crashing. I render to MPEG2 1920x1080 files as a work around.
I'm running WinXP 32 SP3.

"I see now that you can actually turn the paging file off - even though MS "strongly recommends that you do not disable the paging file". Blink, that's how you run?"

Yes. I have been running on 8 gig ram and no page file for months now with no issues at all.... but then I'm not normally rendering avchd, but rather mpeg2 at 25M

Blink - what OS are you running with no paging file? WinXP? Vista? 32 bit or 64 bit?

Vista 64 Ultimate

Hi,

The source for my AVCHD material is a Sony SR12 (PAL). Im' on Vista Ultimate 64 bit.

I have NEWER had problems with 8.0b on 8.0c rendering out to DVD (mpeg2 SD). Even from a timeline with AVCDH or mixed material!!

BUT the problems starts with 8.0c (fails almost in all projects) - IF I render AVCDH material out to the BluRay (1920x1080i 25fps) format using all 4 threads. Seems that the codes used for this purpose has a problem... or is triggering the problem. It seems like a page file size leak, since the page file grows suddenly before the crash...

Please note that everything I render is PAL, one way or the other.

8.0c does NOT fail if I set the number of render threads to less than 1 or 2 (I never tested 3).

8.1 renders (on the same system) every project WITH ALL 4 threads active, also those projects that fails in 8.0c. It is not an CPU overheating issue, since 8.1 can run the CPU close to 100% for hours and hours, without any problems.

My CPU is QX9650, running normally OC:d to 3.82GHz, but during critical tests (like these) I run at 3.2GHz.. My ASUS mobo has the Intel X48 chipset, so the intel CPU is very happy...

I really hope some of you could replicate this problem. It seems that SCS does not take this too seriously if only a few complain about such an issue. They suggested that I should use 8.1. GLADLY - but I cannot use my most important plugins...

I would gladly like to upload an AVCDH clip somewhere, if you could test this with the same settings... but where should I upload the clip?

"I really hope some of you could replicate this problem."

I will gladly give it a try.... but I need a 1920 avchd sample.

Christian:

I got a hold of a 10 second 1920x1080 avchd sample. It was NTSC so i used Vegas (8c) to transcode over to PAL avchd

I then reimported that, threw it on the time line and repeated it for 20 minutes with a bunch of Xfades here and there.

I rendered it out with the standard Blu Ray template set on BEST (1920x1080/50i). The only thing I changed in the template was bitrate. The template defaults on VBR which I hate, and changed it to 25m cbr

At no time during any part of this entire process did Vegas crash. CPU usage (with all 4 cores) was between 80 and 100% and memory usage was between 2gigs and 2.48gigs (I had some other programs going)

Again, I have to suggest that you have a hardware/software conflict going on there somewhere.

Hi BLink,

So the DIFFERENCES were that
- the AVCDH material was actually generated by Vegas (not the cam)
- you changed the bit rate to CBR.

I used the standard template with only one modification, I set the quality glider all the way to 31, but did NOT touch the VBR/CBR settings.

And then - you have no page file... Maybe I should try that too. Just before Vegas crashed my page file grew to about 2,9 gig...

Anyhow, thanks for the testing. Would you still consider to test with an original AVCDG file from my cam, and with the exact same settings?

Christian

No Christian... I believe that Blink mentioned that the clips were indeed AVCHD. But I basically get the same results he does when rendering in that fashion--I cannot get v8.0c to fail or lock up, and I am using all 4 cores. Of course I am using XP 32-bit, so that might be an issue. I have ordered Vista Home Premium 64-bit to try running v8.1, but I haven't yet received it.

So if anyone is interested, I can post some AVCHD clips of a volleyball game that I am taping tonight. I will make sure to record it at the highest resolution possible on the Sony SR11 (it's identical to the SR12, except I only have a 60gb hard drive), and then can upload the whole game to a server tonight after the game. The clips will be anywhere from 30 seconds to 10 minutes in length, depending upon time-outs and such. So it will take me a bit to get that done, but at least it would give everyone the same footage to test--and there would be a good 70-80 minutes of it.
