    I need to get the black level and all that stuff right before I encode my video. I still really don't know how to use the scopes that well and what makes it worse is that I don't know about the two options on the scopes (7.5 IRE setup and Studio RGB) I know that on my camera(Panasonic DVC80 the option for 7.5 Setup is turned off but then on the DVD player, there's an option to have black level on or off) I have a person sitting in front of a black background teaching. There were some shadows showing up on the black background from nearby lights, etc. I just need to have it so that when the customer plays the DVD everything that was meant to be black, IS black. When I look at the waveform scope, what are the permanent horizontal green lines? The television I was using as an external monitor is pretty much useless now because the remote stopped working and I can't get to the brightness/contrast controls to calibrate it. Can I achieve the right levels by using the scopes only by looking at it on my CRT computer monitor? I can post a frame of the orignal captured AVI if someone who is good at this stuff can tell me what filter settings to apply so that it looks "right" on a tv or computer monitor.

  2. Have a look at the following for a pretty decent explanation of waveform display and vectorscope use:

    The above contains a link to a 38 page PDF file called NTSC Video Measurements - The Basics. Direct link: http://www.tek.com/Measurement/App_Notes/NTSC_Video_Msmt/25W_7247_1.pdf
