I might be missing some little adjustment, but my preview monitor (on the computer) is dramatically dim, and muddy. Both the luminance and saturation seem down.
NTSC monitor looks fine, and waveform is showing plenty of luminance.
I recorded Bars off of a video generator onto a fresh tape, and then digitized same into VV4, just to make sure. Problem as above -
Also: the whites on Bars are only showing 95 IRE.
