Hey there Alan,
Thanks for this — I knew that shooting in such low light, and effectively with a chroma key light only, was likely to present a problem. I just wasn’t expecting this! I have some a beginner’s understanding of how this works, but I appreciate you taking the time to explain it.
Here’s a question — if I desaturated the footage and basically removed all chroma information, focusing entirely on the more densely packed luma information, would that solve the jagged edges and go to a smoother image? I’m going to try it, but I’m curious about what you think theoretically.
I’m also curious about why the footage looks fine in my camera’s viewfinder (in playback) and on the clamshell’s screen. The footage was captured onto a MiniDV tape and encoded at that point onto the tape into a DV codec (right?), so why does it change and become so crappy looking just because I move the data from the physical media onto my computer? I can see through my camera and the clamshell that the data has the capacity to look fine — so why can’t I work with /that/ image in my editor? If you or other folks have time to shed some light on the subject, I’d be grateful.
Thanks again for the help.
