Not a video but... it helped me a while back to understand some basics (very basic). I kept it in my favorites.

thanks, I wonder why no one has produced one.

this might help
It's very old, about 70 meg, but has some very good information.

Thank you Doug, will be writing a book for vegas 8 ? I hope so :)

1- What type of information are you looking for exactly?

Some people use scopes for engineering purposes, some to check for legal levels, sometimes for color correction, sometimes for color matching with physical test charts, etc.

2- For engineering purposes, the tektronix.com (or tek.com) website has some good information.

And do check out Spot's link. http://www.sundancemediagroup.com/media/ColorCalibration.wmv

I have dv rack and want to get my lighting right and I was told scopes are the best tool for that.

Actually, when I was making my movie, "Director/Cameraman" I did a very basic, but complete overview of DV Rack. Then when Adobe announced it would not be available as a separate program, I ditched the demo.

I will search it out next week - am shooting all this week, and put it up on Youtube. It wasn't totally complete, but it will definitely give you a head start, if no one comes up with something great.

Patience... and maybe a reminder next Monday?

The basic operations of the Scopes in regard to DV Rack/OnLocation are set out in the manual which is downloadable from Adobe with the sure shot cards.

There are two basic goals using scopes with OnLocation. To record the maximum available dynamic range and to get the required/legal color balance. Use the luminance scope for dynamic range in conjunction with the Zebras. Set the two zebras where you want them, 100 blow-put and 80 skin are the defaults and get the maximum luminance where you want it and maximise the dynamic range while watching the scopes and the field monitor.

It sound complex but it is very easy because when the monitor looks best the scopes are where you want them so its a self-teaching feedback thing. The OnLocation field monitor shows the captured compressed image (what you see in Vegas) so color correcting and exposure and dynamic range is often got right in the camera because you can see what Vegas sees while the camera LCD is uncompressed and low res. You should notice a lot of difference between the camera LCD and the field monitor.

Play with it like this. Set up on your scene and focus then use your iris and ND filters to get maximum dynamic range shown by the widest histogram while using the vectorscope to get the largest luminance values where you want them (like on your subject) while controlling overall exposure with the top zebra and skin tone with the second. When you have got all this as good as you can in the camera you change your lighting (or if on location you direction with regards to the natural light etc) to improve things. IE to get a bigger dynamic range and colors not biased one way or the other or illegal.

Its a lot of fun just playing with it and really just not enough to it to make a video, even though a full OnLocation vid would be good as it does a lot more than color and exposure such as sound error reporting and continuity control. Hope this helped rather than confuse.
