New minor release of Decomb

[Guest]

A new release is available at my web site.

It gives a new Telecide() pattern guidance mode (guide=3) for 25fps to 30fps telecining, as requested by 'manono', and fixes a small bug in default parameter override of the guide parameter.

If we use this new "guide=3" parameter in Telecide, what should the accompanying Decimate paramters be? "Decimate(cycle=6)"?

I assume that if we are dealing with a NTSC 30fps source that we want to reverse back to its PAL 25fps state (if such video exists) then, "cycle=6" is the way to go. Please confirm that this would be correct usage of the new guidance mode.

Hi-

Everything you said was correct. It's for use with 25fps PAL sources that have been telecined to 30fps NTSC. And such material is definitely out there. It isn't common, but I've seen probably half a dozen such DVDs in the past that could have benefited from it, and used Telecide(Guide=3).Decimate(Cycle=6) successfully on a couple of them so far, with better results than before.

Thx for the reply.

I'm working with such a DVD now. Early results (with the line you just posted, basically) seem somewhat satisfactory, but sometimes the movements of characters on the screen seem a bit off, i.e. there is room for improvement (in the "NTSC->PAL reversal process").

My question is, do you think any of the other Decomb options could help in this regard?

Currently I'm trying: reverse=true in Telecide
and
mode=2 in Decimate

To see if either of those can help in this process.

OT but, will we see Decomb for YV12 anytime soon?

[Rhaegar Targaryen]

I sure hope so too. Can't wait to see the performance increase in DVD to XviD encoding entirely at the native DVD colorspace.

I sure would like a guide=startrek for Star Trek in telecine :)

YV12? People want that? Enough requests may trigger action. :)

@Mango

LOL

OMG you bet we do!

Does this also apply to divx? Will divx get no such speed increase?

Yes, we want YV12 versions of Decomb. Right now the only thing that stops me from using AviSynth2.5alpha is the lack of a decent deinterlacer.

@John

DivX4/5 will also benefit heavily from YV12 colorspace. DivX3 will not unless someone can moify nandub to use YV12 data.
