Quality And Color Correction Mixing

[PK]

Hey All  PK Here,

I've edited a short video showing between 2 styles I'm having. One which is "BEAUTIFUL" and the other one which is "HARDCORE".
I've added 2 color corrections to the same vegas project file.

Here's a screenshot of the CC's.


Beautiful:





Hardcore:



My quality gets lower,
Do I have to start another vegas file to make 2 CC's in one video?
or does this have to do with my motherboard cards ?
here are the the processor and gfx card.

GFX Card: NVIDIA GeForce 8400 GS
Processor: Intel(R) Core(TM)2 Duo CPU - E6550 @ 2.33GHz

I Used Fraps 3.6.4 (30fps setting) and Vegas 8.0

The In-game settings was:
Draw Distance - Full
Anti-aliasing - x3
Brightness - Only 4-3 Bars
FX - High
Widescreen - Off

Please help
