Hi all,
As a follow up on my post
http://www.digitalfaq.com/forum/vide...e-improve.html I am trying to determine if the input chain I am using to capture video has any deficiencies. In my opinion calibrating the capture card to my TBC for example will leave me with at most color errors from the VCR itself, or it must be the tape/recording. The AVT-8710 defaults to colored bars when no input is present and I was wondering if they are any good as a reference?
To test I recorded a few second of color bars and opened this up in fcp. By using the RGB overlay I get a picture as shown in the "fcpcolorbars" attachment. When I compare the value's I read there with the ones I found here
http://www.pembers.freeserve.co.uk/T...ical.html#Bars (scroll down to 75% PAL) then they seem to be in the right ballpark, but not quite.
I am not sure how much of a deviation is acceptable or to be expected? Also, I am not sure how to correct this problem. I have been playing around with the color correction in FCP but can't get the image to be as it should be.
Do I correct this in software after capture, during capture in
virtualdub (proc amp settings), do I use the controls on the AVT or do I just leave it all alone
Thanks a bunch,
-P
