How do I combine two combed half-pictures so that the resulting picture
is screened?
Combed input frame:
11111...
22222...
Desired output frame:
12121...
21212...
It occurs to me that I need to unweave the half-pictures, line-double
both, screen both via pixel-sized screens that are offset by 1 pix, then
reweave them.
Look at weave, doubleweave, separatefields and so on....
Thanks. I'll run them through my tester.
I've not found a line-doubling filter and I've not found a screen method
that actually works.
Actually, after I posted, I thought of bob. I think bob line doubles.
I think you can double lines with separatefields,scale combination.
You just need to set right size args to scale filter and use nearest
neigbour interpolation
for doubling lines.
I still think that what you do is wrong thing to do.
To which do you refer? 5-5-5-5 telecine (which is the overall architecture) or screening combed
frames (which is the final step)? Actually, what I already have running is better than what MPV
and/or my TV produces; better than p24->p60 and better than 4-6-4-6 telecine (and much better than
2-3-2-3 telecine frame doubled to 60fps of course).
Why? mpv player already have various interpolation algorithms for
X->60 progressive upsampling.
What about people who don't use MPV? What about PowerDVD?
Note that they are not motion ones, as that one is very fragile and slow.
What do you have in mind, Paul? I don't care about slow. I have a very large, very fast system and
can mount many vdisks that I can run overnight while I sleep. However, I'm not too keen on "fragile"
but maybe I can noodle out a solution to fragile when I see it. After all, I'll have you to help me. :-)
