What am I doing wrong? Whatever colour mode and whatever software (Corel Draw/Photoshop) I prepare my bitmaps in (png/jpg) they end up looking over contrasted or oversaturated like below. What is Vegas doing and why can't I keep or why Vegas can't preserve original RGB colours or profiles? I just simply what to use nice blue background frame and... I just can't.
VMS works on Computer RGB so what you see should be accurate. How are you viewing your rendered file? If it's with a player such as VLC then most players work on Studio RGB range so increase contrast. Try adding Levels FX using Computer RGB to Studio RGB preset when rendering.
Also how does it appear when you add your rendered file to your timeline? Does it match your original?
