Help for Progressif IVTC with a clean Pattern

First : Thank you for your applications. I often use Extensifier and deinterlacer. You do a marvelous job. I do editing for a long time and your applications save me a lot of time.

Second :

I try too convert an old movie for restauration. The original is 720x480 29,97 progressif. I have analyzed the pattern and i found this (for this exemple the picture 20 is the (A)) :
(A)ABCDEFFGHIJJKLMNNOPQRRSTUVVWX(Y)Y

1
7
12
17

21
27
32
37
42
47

51
57
62
67
72
77

81
87
92
97
102
107
111

Every 30 image they are 6 image duplicate for change the 30ips to 24ips
Is it difficult to create a template for delete this duplicate image pattern in your application ?
I have to create a 25P but it is easy after to play the 24P in 25P.
I'm gona try to create a script for apply in FCP sequence with xml manipulation.

If you like my challenge !!!

In any case thank you very much for your incredible works and sorry for my bad english

At last a new posting!

That's a complex pattern. You cannot do fix that currently in JES Deinterlacer.
Do you have many movies like that?

No, only one and I found a solution with iFFMPEG. I cut the movie in 3 part and use the telecine filter for delete duplicate image. The filter modify the pattern every 30 frames if it necessary. But around 18 minutes there is an anomaly in the pattern. So I cut the movie around this and with a 3 min part the filter find a way to reject every duplicate frame. from 21 to the and 1h45min with one file the filter find the solution.

Thanks for your reply.

Exactly what options did you use with iFFMPEG?

If JES Deinterlacer had had an option like "remove duplicate frames but at most 1 in 5" would that have worked?

I don't know exactly the translation but it works for me

How can I send you a capture of the "Telecine" setting ?
