Hi all,

Since I post... a bit much at times, here's a combined status update of 
my proposed VLC changes just so that everyone knows what's going on.

IVTC for hard telecine is, I think, pretty much complete. As I've 
already said, it's still not perfect, but at the moment I don't have any 
ideas for making it any more accurate. I think it's pretty good as it is 

The latest IVTC patch is here:

As for removing soft telecine, the PTS hack is needed first to make the 
input frames have the expected PTSs. Also, although I think that both 
modes belong in the same filter, I also think they're different enough 
so that making the soft telecine remover a separate patch (which would 
go on top of the hard IVTC one) would in my opinion be preferable.

What I want to say with this is that, in my opinion, the IVTC patch is 
ready for inclusion into VLC as soon as it passes review. I won't make 
any more feature changes to it for now, I promise ;)

The PTS hack and soft field repeat support in the framerate doubling 
deinterlacers are, I think, complete. They are currently in need of a 

The patches are here:

I won't make sudden feature changes to these, either ;)

The Phosphor field renderer/deinterlacer is complete, but it requires 
the PTS hack, the soft field repeat support, and the IVTC patch (for 
ComposeFrame()) as a base. So I think it's better to wait with this one 
until the other patches are out of the way.

And finally, soft telecine removal is currently pending development. I 
have a plan, but since the IVTC patch may still change (during review), 
I think it's better to wait for now.

That's the current status. Thanks for reading :)
