Thanked 1 Time in 1 Post
Hi everyone...it has been awhile since my last post...i started my VHS project almost 2 years. Never got back to finishing till now.
i am using Windows XP SP2
what i have done so far
i have captured my videos as per Sanlyn guide: Capturing with VirtualDub [Settings Guide]
my next step is to check signal levels using the original YUV colorspace before any other processing.
i used this script from one off Sanlyn post

# change path statement below to match your system
AviSource("E:\test.avi")
Crop(4,0,-8,-8)
#Histogram("Levels")
ColorYUV(Analyze=true)

this step works great with vdub and avspmod

when i edit the script to check Histogram("Levels"), i get this error with Vdub and avspmod
