LazyWeb: deinterlacing/telecining DVDs [Apr. 8th, 2006|08:18 pm]

Dear LazyWeb, (yes, again)

Best mplayer options for DVD playback w/ fast CPUs ?

There seem to be two dozen "pullup"-style video filters, each with lots of options, but what is all your experimental results? Which feels least choppy on mixed formats? (where framerate bounces back and forth between 24000/1001 and 30000/1001)

I'm looking at you, kvance. :-)

Unless there's something newer than -vf pullup,softskip, that's still what you want to use. It can miss a lot of spots in cartoons, especially where only the mouth movement is edited in video. But for film it's great. The "junk" options for pullup are more useful for television and vhs sources, and the other options aren't very useful.

What really sucks is that your nvidia card can do all this in hardware, but it isn't exposed in the linux drivers.

If you know you're mostly watching film, you can help yourself out by using a 72Hz refresh rate. (Or 120Hz if you have a CRT, then you're invincible except for PAL...)

I'm going from nv into a PT-AE900U (?) projector, so I'm doing whatever its manual recommends for non-scaled 720p HDTV. I forget my modelines... not at home.

Ah, I was totally forgetting about framerate on the other side. Yes, the input mode I'm doing is 60 Hz. If I use HDMI or YPbPr, though, I can do 24 Hz: 1125(1080)/24p, 1920x1080, not interlaced.

I'm pretty sure that's my problem, thanks.

Thanks! I can do 72 Hz, but only with scaling in the projector from 800x600.
