Bad Sony Vegas grain and motion blur?

[parkercorr]

Hey all!

I have an issue where no matter what settings I choose, my Sony Vegas renders videos with a grainy picture quality and it's driving me nuts!

I shot the following film at 1920x1080 24p, shutter speed of 50, with a neutral picture setting:
Sharpness 0 Contrast back as far as possible Saturation: minus2 Color Tone is 0
I only did color correction at a few points - most of the actual 'skating' sections is done with no color correction.

I made sure to check the box with 'match project settings to source" When rendering, I chose 'best' quality, I also chose variable bitrate of 15,000,000 as both the min and the max, I tested both 2step bitrate and no 2step bitrate (no difference), and I tried 'use CPU only' for rendering, and also compared to 'automatic' (no difference). I also chose the blending option for interlacing, and disabled resampling.

The video isn't in 'HD' as Vimeo caps my HD uploads at one per week, but the issues were there in the movie before I uploaded it. Does anyone have any idea how I can get a better quality video? I believe it's something I'm doing wrong with Sony Vegas, as the footage looks so much better before I open it there.

Thank you

Have you tried lowering the minimum bitrate since you are using a VBR? If yes, does it make a difference? What happens if you don't check the "match project settings to source"?

I fixed it by choosing interpolation instead of blending, setting the rendering to baseline instead of main, and by choosing a higher bitrate at constant bitrate!

Glad to hear you got it solved and thank you for posting how you fixed the problem.
