Under video you could select make broadcast safe. Last I heard Avid takes care of this for you. Double check your render settings verses your Avid Import settings. If you make sure the color mode is the same and are using avid codec, you should be fine. Media 100 is a system that doesn’t do this so the levels must be set. For correct black level set that to 18. That should take your blacks from 0 ire to 7.5 ire. If your white are blooming, your blacks are probably sub black. On Avid import try import with RGB colors. this will import using 0-255 colorspace and shouldn’t have to apply levels to fix this.
