How to handle 2:2 pulldown?

[TheSeeker]

Ok I wasn't really sure where to post this as there was no clear spot in my mind. I was just wondering about how to handle a dvd that has a 2:2 cadence? Im told the Friends series is nortorious for this and I am currently backing up Friends and it does look horrible.> Just wondering if there was a good way to get this back into true FILM format? So it can properly be displayed as progressive on my hdtv? Because if i understand it correctly not many dvd players handle 2:2 pulldown detection very good so more than likely it will be handled with the VIDEO mode deinterlacer which can theoretically mess up the video more than if it were using the FILM mode deinterlacer. So long story short, how do I preprocess this 2:2 content so as to maximize the quality? Oh and if this is in the wrong place just let me know and I will ask there.

2:2 is a misnomer. What you probably mean is that you have field-shifted progressive video. That can be easily handled just with Telecide(), which will realign the fields.

Can you post a small clip of your source material for inspection?

In what way is it a misnomer? Im at work right now, but when I get home I can sure cut a little slice of the vob off and post it. But that brings up a few questions. What is the best prog to make a small vob? Wouldnt dvd shrink do this? Also, as I have never posted files to this forum how would I go about doing that?

In what way is it a misnomer? All frames have 2 fields, so any clip that has not had pulldown applied is "2:2". Saying your clip is "2:2" doesn't tell us anything other than that it is not pulled down. I suspect your problem is that your fields are shifted. I.e., instead of:

A B C D E
a b c d e

you have:

- A B C D
a b c d e

There is a one-field phase shift.

You can use DGIndex/DGDecode with field operation NONE to make a HUFYUV AVI, if you know how to do that. Or use any of many VOB cutters, e.g, VOBSplit, from the doom9 download page. Don't use DVDShrink. Put the clip on a web server and post a link to it.
