IVTC, SRestore, ExBlend -> recover original?

[wiseant]

Hi

Just want to make sure that I have these correct:

23.976/24/25 fps to 29.97i soft telecine -> use IVTC

23.976/24/25 fps to 29.97i hard telecine -> use SRestore or FixBlendIVTC

23.976/24/25 fps to 29.97i hard telecine height resized <480 -> use Exblend

29.97i to 29.97p -> ? anyway to "recover"

TIA

As near as I can tell you have none of it correct. Are the sources DVDs?

If so, for soft telecine just make the D2V project file in DGIndex using 'Forced Film'.

For hard telecine you make the D2V using 'Honor Pulldown Flags' followed by an IVTC.

Can exblend be used to recover fields after an improper interlaced resize? I don't know as I've never used it.

29.97i to 29.97p? If the fields are phase-shifted, a field-matcher by itself will realign them. If it's truly interlaced then a deinterlacer is called for.

Nowhere did you mention field-blending. That's when you might use SRestore. And FixBlendIVTC is only for that special case of hard telecine being then blend-deinterlaced.

Maybe 29.97i to 29.97p --> Separatefields()+Resize(width,height*2)+Selectevery(4,0,2)

@manono - thanks

Sorry, I made a mistake in my post

re 23.976/24/25 fps to 29.97i "soft" telecine -> use IVTC - it should have read "hard" telecine

Yes, for soft telecine I use DGIndex as suggested

re Exblend - I will have to ask StainlessS

@Overdrive80
thanks for the suggestion - I'll try Separatefields()+Resize(width,height*2)+Selectevery(4,0,2) and see what happens . . .

Exblend is intended for the same kind of source as this:

although it has had some success with other source here:
