Hasta La Motion!

I have hundreds of trackers to matchmove or stabiliz one sequence. I want to swtich them, set the ‘transform’ and the reference frame by scripting. However when I use the following script it doesn’t evaluate even the number in the knobs appears changed. the image still have no effects, it doesn’t move! But if I manually double click the node to make it active. Then run the script, it works!

Anyone have idea why this happens?

Thanks

hope someone can help me even though I not much of a technical person when understanding hardware and I been thinking of upgrading my CPU for awhile now. Main reason being I’ve been having trouble rendering, whenever I try to render in Maya with mental ray the PC shuts itself off (to me it looks like it can’t handle the information) and it has a blinking light (power light), the only way to restart the PC is to unplug the mains power source.

The PC is a custom built and has the following specs-

Dual Core AMD Opteron ™ Processor 2216 2.41 ghz
4GB RAM
nvidia Quadro FX 1700 512MB
Windows XP Professional Edition X64 Service Pack 2

I’m using Maya 2008

My main piority is for the PC to be able to render out passes and I believe that it maybe the processor that is the issue. So the main item I’m been considering to upgrading is the processor as I dont have much of a budget. So what do people suggest to upgrading the processor? How much would it cost (UK prices)? Any help welcome thanks.
