30p -> 50i (Game videos)

[zilog jones]

I'm planning on converting some game videos to PAL for DVD use. They're all PC games (Counter-Strike, TF, Quake, etc.), so most of them are 640x480 @ 30fps (not 29.97), with a few at 15fps, and some at 800x600 or the occasional screwy resolutions.

What do you guys recommend using for the framerate conversions? As they're CG footage I just know they'll fudge up any fancy motion vector stuff, but is there something less blurry than convertFPS(50) and weaving after that?

Is it worth it trying to filter MPEG4 blockyness? Some of them are pretty mediocre quality DivX/XviD - this is about as bad as they get: www.skynet.ie/~zilog/pics/tfde2_hq.png
That kind of stuff only happens with a lot of movement or scene changes/fades, though.

do it like a telecineing!

avisource("30p.avi")
resize(704,576) # or whatever needed
changefps(50)
#or selectevery(2,2,1)
converttoyuy2()
assumetff()
separatefields().selectevery(4,0,3).weave()

this will introduce slight jerkyness since it is a 2:2:1 - pattern.
but it doesn't distort the image like the blending with convertfps().

btw.: HQ-antialiasing may help against the blocking.

I'll try that out, thanks. How would I change that for 15fps stuff? Sorry, I can't count...

EDIT: Oh, wait - I'm an idiot!

What do you mean by anti-aliasing? I didn't make the original videos, so it's not stuff I rendered myself (the stuff I'm making myself will already be 50i for starters, hopefully :D) - or do you mean some sort of filters?
