i know it probably sounds unorthodox (maybe impossible??), but i thought this was how i had set it up last time for VHS capture. i have no blackburst generator, so my dealer said to set it up thusly in normal situations:
component cables from Mac/Decklink Card to compone. Y component cable to ref in (on UVW-1800), the left one, and on the Y input to the 1800, loop another BNC from that Y input to the other ref in (the right one). then, put the “genlock in” cable from the Decklink to the Video in (left side). with this config, i capture Beta footage with no problems. with this VHS stuff, i’ve tried the composite cable from the camcorder on both ref in’s (and only the left one gives me anything, which is virtually no chroma), and i get no picture at all on the . . .
oh…wait a minute. it helps to write this stuff out sometimes…i see that i never left my front input selector (on the 1800) on “Composite”. ding dong…and yes, putting the video from the camcorder on an actual video input on the 1800 helped a lot, too.
voila. me have color. sorry for wasting the bandwidth again. i have written down these connections and am storing them in a very safe place…
thanks for helping out a bonehead,
