When I render mp4 or DVD mpg the black in the video is much much darker when playing back in windows media player or youtube. When in the project I have to decrease the contrast a lot so that the video appear bla during editing.  Same computer, same monitor. Is there a setting in vegas to make the preview more like the end render?  It's been this way for me from V10-12.  I use 32 bit floating, 2.222 in the project.
