Vegas 7 has failed to render my clip.

[Joe White]

Computer specs? File specs? Rendering specs?

[Deryan Pressley]

what do you mean by specs?:/ sorry

[Danny Hays]

Do you have s faster computer with more ram to try this with?

[Stephen Mann]

Low Memory or Out of Memory does not mean “Not enough RAM”, though adding RAM can sometimes fix a “Low Memory” waning. A “Low Memory” warning usually means that you have exceeded your commit limit. You need either a bigger page file, more physical memory, or both.

One of the biggest sources of confusion over Windows memory usage is the whole concept of virtual memory compared to physical memory. Windows organizes memory, physical and virtual, into pages. Each page is a fixed size (typically 4 KB). To make things more confusing, there’s also a page file (sometimes referred to as a paging file and dynamic RAM). Many Windows users still think of this as a swap file, a bit of disk storage that is only called into play when you absolutely run out of physical RAM. In versions of Windows starting with Vista, that is no longer the case. The most important thing to realize is that physical memory and the page file added together equal the commit limit, which is the total amount of virtual memory that all processes can reserve and commit.

All Windows since XP (and Unix/Linux for that matter) always wants to have page space. Always. Programs (including drivers and codecs) like to and are allowed to pre-allocate as much memory as they want. Even if they are never ever going to actually use it. Sometimes those programs properly deallocate memory, sometimes they don’t (resulting in “memory leak”). Sometimes, programs leave parts of themselves in allocated memory just in case you are going to run that program again. (MS Word, Excel and other Office programs are particularly adept at this). If you have no page file and a program wants to commit some for itself, your PC will crash (AKA, BSOD, or Blue Screen of Death).

Paging file configuration is in the System properties, which you can get to by typing “sysdm.cpl” into the Run dialog, clicking on the Advanced tab, clicking on the Performance Options button, clicking on the Advanced tab (this is really advanced), and then clicking on the Change button. I would suggest a value of 1.5X the currently allocated value. The old advice of 2X or 3X your RAM is, well, old advice when a few MB of RAM was normal. The largest paging file that you can select in Windows is 4,095 megabytes (MB).

Also, Windows supports up to 16 paging files, but each must be on a separate volume, so if you have more than one internal disk drive you could try enabling a Paging File on your second hard-disk. DO NOT put a paging file on an external drive because if it’s not present when Windows boots, then Windows will crash.

Well i just bought this computer a couple months ago. Its a dual processor, and im just really confused.

[Stephen Mann]

You need to tell us what processor, how much memory, hard-disk configuration – those specs.

Also what antivirus program is running? Some, especially those whose names begin with an “N”, are tremendous resource hogs. (I use Microsoft Security Essentials).

In Vegas you can go into options/preferences/video tab and reduce the preview RAM. Some people reduce it all the way to zero and others find improved performance with a small, but non-zero amount. (Mine is set to 512Kb.) This is ram that is set aside for ram preview (Shift-B), but it is unavailable for rendering or encoding. If you’re never using shift-B Ram Preview, then it’s wasted memory.

And you can try increasing your paging file size. It’s a bit difficult to find the settings, so here’s a map:

Open Control Panel
System
Advanced tab
Performance Settings
Advanced tab

Here, select “programs” in processor scheduling.

Now, you can change the Virtual Memory. I would suggest a value of 1.5X the currently allocated value. The old advice of 2X or 3X your RAM is, well, old advice when a few MB of RAM was all that a PC had. The largest paging file that you can select in Windows is 4,095 megabytes (MB).

Hope this helps.
