I'm using an Intel Core 2 Quad 6600 and 64 bit Vista in English. They say Sony software isn't supported under 64 bit, I know, but this doesn't seem like a 64 bit issue, though I may be mistaken.

I have a laptop with XP 32 bit installed, would I be able to install a copy of Vegas on it without angering the Registration Code Gods?

Yes - as far as I remember from the licence - you may install on more machines but on use on one at a time.

I'm currently rendering my files on my laptop and it's at 58% so far no crash.

I tried uninstalling everything from my main computer like DVD player programs and codec packs, but Vegas still crashed when rendering AVCHD.

I went in and changed the threads option to make Vegas use fewer threads (2 threads, then 1 thread), but the program still crashed, albeit much much later (past 60% in comparison to <5%).

Is it a flaw in the way Vegas handles quad cores?

Either quad cores, or 64bit. Do a bug report to Sony using their online form, and give them all these details, including how long your video is, at what point it crashes, if you are using plugins or not, how many threads you are using in the settings panel of Vegas etc. This is a bug that only Sony can fix it, so you should bring it to their attention as they don't always read this forum.

I found also same issue with my Q9300 and Vista 64-bit. I made also a bug report. We'll see what can be found and if Sony can provide some help on this issue.

I made a bug report to Sony before coming here.

I tried running in XP compat. mode but got this error message:

My XP laptop rendered (very slowly) the entire thing to the end, but the video exhibited strange blocks of colors about 2 minutes in and then became super jumpy and garbled, completely unwatchable, for the remainder.

"Either quad cores, or 64bit. Do a bug report to Sony using their online form"

The relevant product manager is aware of that issue discussed here, I can tell you for sure.

I recently read about a 64-bit version of Vegas Pro. Does anyone know if they're working on one for Vegas Movie Studio as well?

I got reply from Sony tech support where they said only Vegas Pro will be 64-bit, not VMS. And they said during this year..

About the rendering problem they suggested to allocate more memory for Vegas and try to reduce processing threads. With 4, 3 and 2 threads I got Vegas crashing. I also allocated 1024 MB memory for Vegas. It says that it is maximum amount although I could allocate little bit more from 4 GB.

@ Timpe,

so it did not help. You can only do two things:

- render to mpeg2-based footage, that will be more stable during rendering
- wait for Moviestudio 9b.

I'm a newby to this forum and very recently changed from many years of being an (unsatisfied) Pinnacle7/8/9/10/11/12 user to VMS, only to find out that my projects, when rendering 1920 x 1080 AVCHD, consistently crash irrespective of the duration of my video. I sincerely hope that the cause will be remedied quickly as to restore my confidence in this product. Sofar it was a joy working with VMS as I did not experience a single crash while editing, which cannot be said about Pinnacle. But I do still have an unfinished product, which I cannot show to the world. I meanwhile filed a bug report.

Josenegro, what kind of system are you running? 64 bit windows? Quad-core? I'm curious to see if there's a pattern, here.

I had the same problem and thought it was because I was using an amd tourion 64 laptop with only 2 gig of ram. but then I tried and advance render to a different codec and it rendered just fine. I had to make sure I turned off all other programs and it took about 2 hours to render 4min video at the highest resoultion. Needless to say I need a faster more powerful system for HD. I rendered the video in several codecs as mp4 and to burn for dvd. and toplay on my hard drive. I did have a couple of crashes while doing the edits and adding music. I found by saving the project after each transition or effect limited the crashing

good luck

Click on my name and you'll see the environment I'm working with. In this case Vista 32 and not 64. I received the following reply to my request for assistance from Sony:

Go to Options / Preferences / General tab... Scroll to the bottom and uncheck the option that says 'Enable no-recompress for long GOP rendering' and try rendering again.

Have tried it and it seems to work, but I had sofar insufficient time to really test it out. It did render without a crash, but couldn't find the file back on my blu-ray disc. I'm still a newby. Will keep you posted.

Well then it seems like it's not just a 64 bit problem, which is both good and bad. Good, because they're more likely to fix it, bad because, well, they released a software package with broken AVCHD support.

You will probably find the crashes only happen when you trim the AVCHD clips in your project and apply a transition.

Rendering non trimmed clips will work OK.

This has been reported to Sony who are investigating.

A work around is to render the project to AVI full HD (thought you will need a lot of disk space!) and then make a new project and place the large AVI clip on the timeline, then render AVCHD. The quality looks fine to me.

Hopefully Sony will have a fix soon.

I also have a quad processor with 64-bit and the rendering blows up within a few seconds. My movie does have transitions. I am now rendering to the hard drive. It seems to be working. I will see how it goes when I try to compress and send it to the blu ray disc.

Has anyone experienced that with the 9b (build 92) version the impossibility to render AVCHD 1920x1080 has been resolved?

It has been not solved!!!!!
