I'm building a roll in reel for ingest into an EVS unit for a live show. I've got matte key elements and I've separated out the fill and alpha video. As I understand Avid's matte key structure the fill should be 16-235 and the matte key alpha is actually full range 0-255. Now when I pull out the alpha channel I have super whites and blacks as would be expected. I am hesitant to color correct this into 16-235 as I don't want to distort how the switcher will interpret the key signal. I'm building fill on one tape and alpha on another tape with matching time code so they can sync roll when ingesting into the EVS unit at the remote. I know the TD can tweak his linear keyer but I'm curious if anyone more familiar with the EVS feeding a key signal to a switcher if I should infact bring the matte signal to reside within 0 to 700 milllivolts? TIA
