Thanks for the detailed response. Rephotographing the CRT is definitely something I’m no stranger to, but that being said I know the conditions that are required for it to look good (complete darkness, distance between me and the tripod to not accidentally nudge it with my stupid rolling chair, etc.), so I’d rather go with something that I can plug in and record at 2 in the afternoon.
I’m looking at the Decimator, it leads me to a noob question I’ve wondered for a while now… is SDI basically just BNC? So I’d be able to go from composite out to SDI using a BNC adaptor (or a composite to BNC cable?)
