Best MPEG-2

It would help if you posted your specs. Jitterness could be due to any number of things. Primarily, it could be your decoder, but it could also be a slow processor, old video card/video card drivers, etc.

Also, when using the Hauppauge decoders, did you fully uninstall the old one before trying the newer ones? I remember experiencing stuttering from the version 5 decoder I got from shpvr, but the version 5 decoder I got directly from the Hauppauge site seemed to fix it.

Yeah, I've tried the Hauppauge Ver5 decoder.
Doesn't do any kind of inverse telecine for film sources.

Record Joey, watch closely on horizontal pans. Jerk, jerk, jerk, jerk.

i've got a nvidea 4000 128mb graphics card
pentium 4, 2.1 ghz

see, i don't even understand what iniverse telecine is. Everything works fine, but regular tv seems to work better when it comes to fast action sports like basket ball... that's all i'm saying!

Inverse telecine is nothing spectacular. It's just the process that NTSC television has to go through to show film sources.

Quickly:
Film sources (most primetime tv, movies) are shot in 24 frames per second. NTSC video (your television, but not your monitor) is designed to output in 30 frames per second.

Technically, it outputs in 60 "fields" per second, two fields per frame. The first pass will display lines 1,3,5..... and the second pass will display lines 2,4,6.... THAT is interlacing. There's a little bit of math involved here, but basically it boils down to when you want to show 24 frames per second on something that's designed to show 30 frames per second it gets a little weird.

It's no problem most of the time for the TV but when you try to play back a film source on your monitor (a progressive device) and it's not deinterlaced well, it can get jerky during movement and pans because of the 24/30 fps telecine process.

Just google for "inverse telecine" or "3:2 pulldown" if you want to know more..

thanks jason, that's helpful--it still makes it difficult to watch sports

[j3flight]

Yeah, MPEG doesn't keep up well with fast moving sports unless your bitrate is pretty high.

Make sure you're capturing at a high enough bitrate, that's all I can say... VBR 6.5 - 8 or a little higher if you want to experiment.

Wow...does it just project a hologram at that point?

I do the 6-8, and have no complaints. I use nvidia, which works w/o a problem. I used the intervideo ones, and they jerked a little. Oddly, MCE says it prefers the nvidia and won't approve the interv ones, but the intervid is the only one it will use.

Actual results may vary is the moral I think.

I doubt you'd get 20000. Infact, the call probably fails and you'll end up with whatever the driver defaults are. Keep it below 12000.

I found when I went over a certain threshold that the picture didnt seem to get much better, but the files used much more disk space. diminishing returns and all that...
