Converted to DVD fine but stutters...

[VicSedition]

My problem does not lie (I think) in the conversion process... I'm wondering if my system is too weak for my encodes and is resulting in stuttering... by stuttering I mean this.. -> A movie that encodes correctly with a2d (m2ts files), will, in "panoramic" scenes (mostly) seem to be skipping frames or like a bunch of stills in sequence (this is VERY slight for me)... Not enough to disrupt the movie and to most people is unnoticeable. It is not constant and occurs rarely in the movies. For me tho it is a constant irritation I see more and more. Could this be the result of a weak CPU..? I've heard that encoding is CPU reliant and that a non/integrated video setup doesn't have much to do with this.. If that is true I have a AM3 550 BE (Phenom2x2) 3 gigs of ddr3 a GA785gmt-u2hd MB... is this too weak for my needs... should I upgrade to a quad core to get desired results or am I missing some settings arrangement? I use a2d for my m2ts encodes... usually hcenc 2 pass with quenc as audio (recommended for BDrip conversion ie my m2ts files).. other than that stock settings besides the ntsc. Any info is welcome and greatly appreciated. Sorry if I missed pertinent info as I'm newb.

Encoding speed is mostly CPU dependent, but even a slow PC can still encode most anything without errors. Just takes a lot longer. However you may see stuttering on playback if the video card and CPU are a bit slow. Not usually with DVD material, though. More often with HD video.

BTW, What's 'a2d'?

You say the stuttering is very mild - I would suggest it is also in the source. Even studio shot films can stutter or judder slightly on pans because 24 fps simply is not enough to get truly smooth movement, even if projected back at a frame-doubled 48 fps.

Unless you can put the two side by side using something like an avisynth script with a stack command, and go through them frame by frame and show that frames are being skipped or blended during the encoding process, I suspect that you are seeing what was always there. You have noticed it now because you are more aware of the quality of material you have encoded yourself. Or perhaps you have a 120 Hz TV that only does 120 Hz for Bluray and not for DVD upscaling, so the source appears to be smoother than the conversion.

My HD TV plays back 24ps material at 24fps, and pans sometimes stutter. It is just the way it is.

Thanks. Its not terribly bad but its just a matter of pride when others are watching too. To clarify it is stuttering on my tv through the dvd player... I'm not watching on comp. Thanks Guns1inger as always. The 120 hz scenario seems interesting.. My tv isn't that great could it also be player related? Could you explain the dvd upscaling thing? These are bdrips I convert which usually result in greater quality.. my intent is also to purchase BD equip later and utilize the end result a little better than my 4:3 digital piece o crap. Also I have not noticed the source m2ts files containing any stuttering but then again I am watching those on my computer. I'll have to do some comparisons through the comp like you said. Thanks again.
