Please help? I am running the 30 day trial of Movie Studio Platinum 9.0b on a 64 bit Quad core with 6.Gb of Ram.

I have created a couple different projects about 5-10 mins length using about 20 different .mt2s files from a sony HD handycam, with one video track, two audio, and a few text overlays.

When I try to render, Vegas crashes consitently, or freezes with the elpased time still running but no frames being processed. I have tried playing with a variety of render parameters suggested in various forums and keep having the same problem.

Can any one shed some light on the compatibility o Vista 64 bit and Movie studio? or anything to try or a direction to go?? Please!!

I was having the same problem except with Windows 7 64 bit. Sony Vegas Movie Studio Platinum using .m2ts AVCHD files from my Sony camcorder. It always crashed during rendering. I did some research and found a lot of people having the same problem with Vegas Pro and Movie Studio. I found the solution on a Sony Vegas forum somewhere. I have lost the website link to the information, but below is what it said (I copied the info to a document and saved it for future reference. I pasted it into this message.) This solved the problem for me, and according to the forum where I read this, it solved it for other people also. I hope it solves it for you.

Google "CFF Explorer", download and install it.
Most 32 bit exe and dll files have a 2 gig maximum memory cap. I've been playing around with CFF EXPLORER (free download) which is a program that allows you to easily open the exe or dll and click the 2 gig memory switch that allows it to use more than 2 gig.

(the .dll's listed below are in the program's folder in the subfolder FileIO Plug-Ins)
Reset the memory flags in
>For Vegas Pro: vegas80.exe or vegas90.exe) ... or for Vegas Movie Studio Platinum: VegasmoviestudioPE90.exe)
>m2tsplug.dll
>mcstdh264dec.dll
>sonymvd2pro_xp.dll
to "greater than 2gig"

How to do this:
open the CFF Explorer program as administrator
goto file\open
then find the file... (one of the files listed above)
On the left side you'll see "NT HEADER".... "DOS HEADER"... etc
Highlight "FILE HEADER" under "NT HEADER"
On the right side you'll see a chart and in the bottom right corner you will see "CLICK HERE"
Click on that and a check box menu system will open.
Scroll down the menu list until you see "app can handle > than 2gig address space" and check that.
Save the file and close.

Open the others and do the same.

MAKE SURE YOU DO A BACKUP COPY OF THE FILES BEFORE CHANGING THEM JUST IN CASE YOU GET INTO TROUBLE!!!

I also use Win7 x64 and have the same problem with the Sony AVC encoder. With projects of a running time over about 10-15 minutes, I CANNOT get a full render. I get "render failed for an unspecified reason" What a piece of garbage.

Be sure to check out my earlier post about Core i7 machines and hyperthreading. That COULD help.

Any software engineer that writes code that gives so little diagnostic information should be fired! I have no idea of where to start trying to fix this problem.

I tried the fixes listed above, but they didn't fix the problem. I am going to resort to splitting into smaller projects and stitching them together later, but I should NOT have to do this. I'm using video from a Sony camera with Sony's software using Sony's AVC encoder...I mean...come on!

Does anyone know of a good way to debug VMS9?
