If not, can anyone describe an algorithm i might implement to deduce the syncronisation of frames? I guess I need to spot frames that exhibit combing between fields, because 2 sequential combed frames would always correspond to frames 3 and 4 in a 5 frame 3:2 pulldown block. What's a good mechanism
for detecting combing (in effect, spotting interlacing).

Do a search for yuvkineco.

I also have written tools for aiding detection if source material is 2-3 pulldown but I assume that you know it is and want to remove it.
