I have a video which was posted on the archive.org, but obviously captured from a commercial web site. There is also a copy of the same movie on YouTube, but it also has the same problems. Since it has my grandfather in the cast I want to restore it using some good software that I already have.

I have tried various strategies to detelecine it to nominal 24fps without success. I get the 3 P frames perfectly, but the 2 I frames come out scrambled. If the 5 telecined frames are labeled Ap,Bp,Cp and Di,Ei and the original 4th frame of the move as D The Di has parts of Cp as well D in both T and B, then Ei has pieces of D and A2p, but something is scrambled. Bobbing it TFF I see what looks like interlace lines from C and D in Dit and similar mixtures in Dib, Eit, Eib. Deinterlacing with VirtualDub creates a messy D, but good ABC. I have an avisyth procedure which often works on ghosted videos and produces more horrible results. I think this might have been a deliberate scramble which would look ok on the old SD TVs, but not on the web or new HD TVs.

I have provided both an original clip and a bobbed clip at.

I am very expert with VirtualDub, but a novice with avisynth. Any help would be appreciated. It seems to be a ghosted telecine in a pattern which repeats every 4.5 lines.

Both your sample videos were playing upside down for me.

The "original" sample appears to have been resized while it was telecined, and there appears to be missing frames, but it's pretty hard to tell what's going on as the sample is only ten frames long. Can you upload a longer one? A couple of minutes would probably be enough.
