Hi Jan,
> Do you have any references for state of the art interpolation?
No but at the end of 2004 I run a comparison among all deinterlacers found
and this convinced me that the best algorithms are those from Alpary
Deinterlacer, TomsMocomp and Smart deinterlacer for Virtualdub but the first
which is available also for Premiere and Ulead. The Footage I used was pure
PAL video becouse in case of telecined source a simple DeComb would have
been a better choice.
I like the Lanczos Framerate ConverterHQ uses to stretch the frame after
bobbing the fields (though I dislike bobbing in general) and the Lansin for
the frame conversion.
In conclusion I think that Applications like Cleaner or even Procoder are
old and outdated (Squeeze is different becouse I look at it as a kind of
drawer full of codecs) and there is room for new compression suites oriented
to the upcoming generation of consumer 1080i et similia. Making those
aiming to the Indy Market to get the most out of their HDV providing them
tools to deinterlace, apply cinema gamma (even without all the preset of
magicbullet or 55mm or the Final Focus bokeh) is the challenge. Rsizing a
4:3 HDV (1080*1440) to a 2K (1556*2048) necessary to print on film et c in
an intiutive, usable (fast) GUI are to me the tools around which to build
the Compression suite of the foreseeable future...
