AVI Tech Question

[sisabet]

Okay - so I have all of these avi video files that are, I assume, all using mpeg-4 in either a divx or xvid container. Am I right so far?

So - I also know that these files (most of them are bittorrented) are labelled something like "Desperate_Housewives_1x05_hdtv_xvid_tcm" or "Lost_1x13_hdtvlol_avi" or something. This is just an example - I've never even downloaded Lost.

I have 2 questions:

1. What does "LOL" and "TCM" mean? Is it something to do with the audio compression?

2.Is there a way to correct for what I assume is a frame-rate inconsistency? For example: certain avi files seem to play jerky for me - the movement looks a bit *off* - now the audio will generally sync but the actual play is just - stuttery. I am not certain but it may be on the files labelled TCM (I need to actually look at this in depth). Coverting the avi to mpeg2 does not improve the movement issues, probably because this does not correct frame rate problems.

According to g-spot, these files play just fine and I have all the necessary stuff running in the background.

But I want smooth looking video - How do I achieve this? What am I doing wrong? Is this a PAL-NTSC thing? I thought we had worked all those issues out. Do I need to force film something? Force feed something? Should I use the force?

First of all - thank you.

Now I am at home and looking and I think it is an issue of me and my PC because it looks like all xvid files appear (and clip as such) jerky.

My thoughts are that I am missing something that I need to have. I uninstalled Xvid and redownloaded and installed it and the problem still remains.

I shall let Clark Demonstrate the issue at hand. This is a 13 sec demo (cause this is the vid I am working on): The first part of the demo is Clark being molested by whorey sorority girls. As you can see, the footage is all...jerky. The second part of the demo (at 7 seconds in) is Clark being molested by a cheerleader in the weight room. As you can see, the footage is smooth and flows.

What can we gather from this (other than Clark is very confused and quite jumpable?)- The jerky sorority girls stuff is from smallville.s04e13.hdtv-lol (VDub says it is xvid mpeg-4 and fps is 23.976). The smooth (yet still just as horny) cheerleader stuff is from smallville.s04e01xsvcd.

So there is something up with me, my PC and xVid. Or Mpeg-4. Or something. And it has to just be me and not the source because these things play well for other people. It is just me. And it looks like this ::points to jerky sorority girls::
