First things first though, calibrate your monitor and your TV with some test patterns at least.
The calibrate your capture system to make sure you are capturing the full dynamic range of your source. (ie. that it is no too bright with blown out whites or too dark with crushed blacks)
If the source is still to bright, then set new black and white points.


I agree Laserman,

I use the ADVC100 for all my captures (including PAL/NTSC) and this has a setting on it for IRE 0/7.5 (ie black level) if capturing PAL, IRE should be set to 0, and if US NTSC, then it should be 7.5 This made a vast difference to the brightness level of my SW captures a few months back and now only a small amount of filtering is required to bring the video ready for DVD

I have the AVI in avisynth, do the IVTC and resize as required then frameserve to VD and use a few of their filters. The order of filters does matter, do experiment a little and see what effects you get. I have had to change gamma and brightness so the image comes out right (to my eye anyway) and after testing a few clips on a test DVD on the TV (the monitor is a lot different!), I then did the entire encode...

Laserman, what type of calibration do you recommend? (Yes, my AVI is DV Canopus)
