Hi all,

I need some help there :)
I have a PAL source tat is a making of, one of these bonus made of a patchwork of interviews, shooting rushes, movie teasers...

Interlacing2Reader gives me the following results :
Code:

interlaced: 39
progressive: 28
filedshifted: 26
real_interlaced: 28
ttf: 77
bff: 2

What would you do in such situation to make the source as progressive as possible ? I would like to use the usual combo Limitedsharpen + LRemoveDust.

Thanks for any advice.

It's nearly impossible to make it progressive in a clean way unless you treat every part separately. That is, use field matching (=Telecide) on the field shifted parts and deinterlace the interlaced parts. Depending on the amount of different parts, it can be a lot of manual work.

Thanks Boulder,
That's what I thought. Actually I tried a simple TDeint(order=1) that worked somehow correctly. I will stay with that, I do not give a lot of importance to the bonus anyway (I encode them in mode "Half size and half space" in DVD-Rebuilder ;)).

BTW it was a nice test for that Interlacing2Reader function.

You might want to add the parameter tryweave=true in TDeint, it should process the field shifted frames correctly. Also if you already didn't use it, the latest TDeint version gives a nice performance boost :D

It is indicated as "true" by default in the doc of my... old 0.9.6 version (almost 2 years old. I think I'm going to take the latest one right now :lol:).
