Loosing saturation when frameserving from Vegas

[Bencuri]

I have Sony Vegas 12. I have problems with colors when frameserving. That is: I load an mpg to Vegas. Do nothing, start frameserving it by Debugmode Frameserver. I open in Avisynth. I can see that the colors are different when I open the mpg directly in Avisynth. I loose some saturation if I frameserve from Vegas. You can see it on the photos:

What do I do wrong? I notice this all the time I frameserve from Vegas. I frameserve with YUY2, the other options are RGB24 and 32 but they give no different results. The code is DirectShowSource ("Video.avi/mpg"). So I added no filters yet just opened the mpeg and the avi.

I don't know what your tools are doing. The levels are off quite a bit. Darks too high, brights too low
Vegas levels corrected:

ImageSource("Vegas.JPG")
converttoYV16(interlaced=true)
crop(0,0,0,-1)
levels(32,1.0,225,0,255,coring=false)
turnright().histogram().turnleft()

I don't do anything just opening the files. Anything Vegas does is an internal default setting.

You're using studio RGB in vegas - RGB Black reference level 16, White reference level 235 . But most other programs use "computer RGB" Reference Black = 0 , Reference White = 255

In older versions of vegas, the simplest solution is to add a levels filter (studio RGB to computer RGB preset) before you frameserve out

Thanks, that is the solution exactly.
