yo,
Im trying to batch automate the process of converting video to be tv safe using virtual dub. Simular to After Effects "Broadcast Colors" filter or photshops "NTSC Colors" filter
I found this on the net and it gave me an idea:
Here is a general rule for the colors you should use when creating graphics for television.
* No color should have any R, G or B value higher than 235 or lower than 16.
* Black is not black, and white is not white; instead, use RGB values of 16, 16, 16 for black and 235, 235, 235 for white. It looks terrible on your computer screen, but it looks normal on TV.
* No color should be over-saturated in any one channel, so values in the R, G and B channels should be within 191 of each other. (For example, R 200, G 100, B 50 is good, while R235, G 16, B 16 is not.)
You can read the full artical here (http://www.dvdcreation.com/2003/09_sep/features/dvd4designers10309043.htm)
OK heres my question, with all of the above in mind,, will the following processing settings in virtualdub achive this? See screen shot:http://www.towknee.com/images/ntsc_color_safe/ntsc_color_safe_with_virtual_dub_copy.png
