annoying IVTC problem (in general) therefore, function, general

andy

Has anyone come across any sources where the pattern rapidly changes therefore you can't use the manual (pattern) method as covered in the tmpgenc ivtc tutorial so you have to go frame by frame selecting them manually? Well don't you find it annoying after you've doubled checked and INTERLACED artifacts remain so you have to check it again after you've encoded the same thing happens again and again?

I somehow need some sort of application or script (i've tried avisynths isCombined function but that isn't really accurate) that tells me where the interlaced artifact is so i can correct it or blend the interlaced frames but NOT the ivtced frame. Im working with MPEG-2 (SVCD) by the way. Any help would be appreciated

There are some AVS plugins for 'smart' IVTC by analyzing frame/filed differences. For instance Decomb. It requires some reading of manual of course.
Btw. TMPGenc has also analysing of video before IVTC (at least earlier versions had, but Im not use it more, because is slow).

Don't expect miracles. If cource video is incorrect, it will not work well.
Condition is actually this: must be flow of 3 non-interlaced and 2 interlaced frames cyclically. It may sometimes be broken little, but nor much, and not so that you have 5 interlaced frames in order or similar.

I succesfully IVTC-ed many Chinese DVD with TMPGEnc, later with Decomb.

There is no such thing as ivtced frame in 30 fps source (telecined source).

of course, you can just do your TMPG encode with quot;auto 3:2 pulldown detectionquot; set, then it'll encode interlaced when there's no discernable pattern, and encode film when it locks onto a pattern.  saves a lot of time at your end, and the efficiency doesn't suffer all that much.

mencoder (part of the mplayer package) has some very good dynamic ivtc algorithms. I use it to help me backup tivo captures.
