Sony vegas pro 12 error

[newbieclocker]

Hey guys,

Before anyone says, my perfectly "legitimate" copy of sony vegas would cost me £300 to buy. This is unrealistic and expensive and this software is essential for what I want to do.

I have been trying to render a 1 min long video in 1080p which I recorded with FRAPs at 120 FPS with custom settings; 1920x1080, high profile, allow source to adjust frame size, 29.970000 FPS, none progressive scan, 10,000,000 max bps, 8,000,000 min bps, render using open cl, 48,000hz, 384,000 bitrate.

However I find the preview of the render to be distorted and after a few seconds I get this error;

(When rendering onto my SSD and HDD)

I used to get an error referring to a FRAPs .dll but not any more and I still have FRAPs installed.

I have an AMD 7950 OC'ed 1100 core and 1500 memory, a i7 3770k OC'ed 1.25v 4.5GHz this may not be stable.

I have the 13.8 catalyst driver and a ffcshow codec pack.

I have tried run as administrator, reinstalling, run in windows 7, run in vista, I have tried vegas pro 11 and rendering in internet HD 1080p and still nothing works.

I am going to try and add more voltage to my CPU but before my system format I was running at this voltage.

Thanks.

EDIT: 1.255 still doesn't work. Going to try 1.3v and stock on GPU and CPU.

EDIT 2: At 1.26v my render managed to complete. Going to have to find out why it needs more volts all of a sudden...
