Gamma for youtube

Ok, I'm trying to wrap my head around this and I've been trying to understand color spaces in vegas and how it works.

This is a resource I've been trying to understand:
http://www.glennchan.info/articles/vegas/v8color/vegas-9-levels.htm

When I export I generally use wmv, since it looks identical to how I see it in Vegas.
But if I want it exported to AVC (.mp4) I put an adjustment layer with a levels preset (Computer RGB to studio RGB) hence getting a washed out image in vegas, but correct image when playing back the file in WMP.

But when I upload to youtube, it either is washed out or right on the money.

I don't feel like I have control over how it will look on youtube.

Any thoughts?

I don't think anyone can tell you can exert control over the finished look of the video as served by Utube. Ever. You also must admit you cannot control what the individual viewer sees on his client PC either.
So this might call for relaxation in the following scenario:
1) Examine your review and test methodology - very suspect at this point
2) Fret less
3) Upload a file type that most closely matches what the Utube will "correct" it into.
4) Don't ever compare a .wmv format as some kind of standard
5) Don't believe all Utube viewers are going to play in WMP - in fact recommend that they don't.

Assuming the same source, that is a playback issue; browser, player, monitor, video card.

Sebastian,

Are you using your scopes? I find that as long as I keep my video within legal levels (0-100 IRE) my exports are consistent when viewing on youtube. I have found however that some of my browsers act differently. Most browsers/players stretch legal video (16-235) to computer level video (0-255). The exception at least on my system is Chrome which does not expand the video to computer levels so it looks slightly washed out.
