Why is my quality so bad?
 

I use this tutorial:
High quality video for YouTube and Vimeo from Sony Vegas

Its extremely good and professional. I suggest you have a look.
(NOTE: I remove the Lanczos thing due to my video being the correct size anyway).

Anyways, I record cod clips, but my output is terrible.
Here are my in game settings
1024x768 (:<) (NOTE: I can "downsample" to 16:9 1920x1080, looks better, but no point as my quality is terrible. However, the vid at the end is recorded @ 1920x1080)
4:3 Ratio
4xAA
Max settings in terms of textures etc.

My nvida control panel.

In game, I put the timescale to 0.1 and record @ 60 fps.
Speed it up in vdub = 600 fps. No compression (uncompressed), no audio.

Vegas render settings.

Blend fields as in the bubble vision guide. 60 fps due to 600/10= 60.

Render with Frameserverdebug so no need to render out and therefore keeping quality.

Megui settings:

This is my result
1280x720-QTGMC-ST-muxed - YouTube

Why is the quality so bad? Btw, no audio for it. Is it the megui settings? Did I do something stupid?

This person uses Xvid compression codec In sony Vegas, records @ 1920x1080 and renders into 1280x720.
Example of his quality: Why is mine so bad, is it the compression, the codec? Should I be using Xvid, not megui?

Cheers
