BACKGROUND:
I have a music video MiniDV that I captured from a camcorder. Its a nice fat 13GB file now. Originally, the video was recorded in one of those municipal access TV studios. I could see 8 pixels of noise at the bottom of the DV, which tells me its the sync signals that you get from an analog camera. Someone captured the analog onto a PC or Mac and edited the video. They finally backed it up on a MinDV tape, which I have captured as a DV file. Beyond that, I have no information as to what they used or how the studio did their thing.
EXPERIMENT TO MAKE A DVD:
I am experimenting with improving the video. Its not bad but I believe I could find some filter(s) that will make it better.
Using Vegas 4, they have a filter that converts from "Studio RGB (16 to 235)" to PC RGB (0 to 255). When I did this, it looked better to my eyes. A veil seemed to be lifted. Then I rendered the filtered video to an AVI and played it using WMP. It looked decent. Then I ran it through CCE to make a MPEG. I made sure that I used the Luma setting for a PC (0 to 255) in CCE. Overall it looked good but the faces seemed overly bright and shiny.
QUESTIONS:
(1) How can I determine the source RGB luma on the DV I captured? When I ran it through the vectorscope on Vegas 4, it clearly showed RGB signals from 16 up to 235. The vectorscope has two settings:
o 7.5 IRE Setup
o Studio RGB (16 to 235)
I tried the Studio RGB setting both on and off, using the Vectorscope, and got the distribution in the 16 to 235 range. Can I assume its Studio RGB that I'm dealing with?
(2) Should I change the RGB on the AVI file, or leave it alone?
(3) After reading another thread, I am getting the impression that perhaps I should make test DVDs with short samples of video rather than use my PC monitor as an indicator of how the final product will look. Is this recommended over eye balling what you think looks better on a non interlaced computer CRT?
(4) Lastly, is it recommended to get a TV monitor and drive it from your PC using a S-Video TV adapter as a method of seeing what your video would look like on a TV? I notice that Vegas 4 does have a TV monitor out mode.
NOTE: I have a dual Matrox G550 video card that could be rigged to drive a TV monitor.
