No, I'm not going to ask a question about computer vs studio levels; there's enough of those already.
In those 'Levels' threads, the issue of fading to black is mentioned, with the suggestion that it is necessary to add a track of solid black with rgb levels set to 16,16,16 for the fade to be correct.
My question is: Under Preferences/Video why not set he default Track Fade Bottom to 16,16,16?
