hesatation problems

[guest]

I have what I guess would be called a glitch instead of a problem. I record some tv with my
pc using showshifter in avi form with divx. Sometimes on playback it's a little jerky and
can't seem to figure out why. Here's some extra info that will be needed hp 1.8 gh xp pro
using aver studio pc card 640mb ram and nothing else ever runs while recording.Don't have any
codec packs just the ones i use. any ideas will help. I use zoomplayer and powerdvd for playback.
thanks

It's probably a lack of cpu, as capturing from television to your pc is hard enough on the cpu, but compressing to avi at the same time (i assume you are compressing to a one-cd or two-cd avi and not making a huge, uncompressed avi) is a very big task, and capturing straight to avi with divx without dropping frames is a difficult task with even the fastest cpus. It's not the playback that is causing you problems, it's the actual capture, you're dropping frames. It's always better to capture to the least compressed possible, then reencode afterwards. If you capture straight to avi, it's best to do so using lossless codecs like huffy or mjpeg, but your avi for a standard-length movie would be over 100 gigabytes. Few users have the hard drive space to spare to do that, like I don't. That's why I capture to dvd quality mpeg2 (a standard-length movie comes out to be 6-10 gigabytes), then I encode from mpeg2 to avi with divx afterwards.

The speed of your cpu when all you do is encode from one format to another, like from dvd to avi, affects the encode only in encode time (it will take you longer). Not so with capturing from tv or vhs, the speed of your cpu directly affects the quality of your capture, as you are capturing in real time and your computer can't slow down to catch up with the work, so it drops frames. 1,8 GHz simply isn't enough cpu to both capture in real time and compress the video that much.

Thank You Much.

Well I took your advice on going back to mpeg2 and the original program for
AverTV Studio only records in mpeg 1 or 2 and vcd so i thought it might be time
for a complete wipe and install of everything.Alas the same problem arises
Iget a fantastic picture but on playback it still hesatates and is jerky.
I've tried all 3 settings and still the same result. Any other thoughts?
It used to record great with either mpeg2 or divx can't help but think I'm
missing something. The only way i could even get it to record with aver was
to install filterSDK? THANKS

Hmm... to be honest, I don't have a clue because for one thing I'm not that big of an expert and simply might not know, and for another there could be a dozen reasons and they're all hard to find. Maybe something on your comp is conflicting, like I know that I have had problems before with some apps after installing Pinnacle or Adobe apps, because they simply try and take over all the others. Or it could be some playback problem (you might not have installed any codec packs, but players come with their own codecs, so do other apps like Nero, etc.), and they could be conflicting, or maybe some capture card setting, or setting in Aver, or something else. Like I said, I can help with most general video issues, but i'm no techie. The only thing I can suggest is to try and post your issue on a forum that deals specifically with capturing video, there are probably more experts there. You can try a forum like the one on Doom9:

after through cleaning and putting just the progs needed back on it still did it on play back so i thought let's try some new players. got rid of mine and went to your site dowloaded bsplayer and vlc and played back great. only problem left is the sorry ass mpeg codec that comes with aver, tmpeg virtualdub or nothing will reconize it to let me reencode. do you have any idea how to get rid of their mpeg codes and replace them with some decent ones? thanks

Well you can install this one and see if it helps:

If you can get hold of a copy of PowerDVD or WinDVD (not free) they also come with good mpeg2 codecs. But it's strange that tmpgenc won't recognize it, virtualdub won't recognize mpeg1 by default, only mpeg2, and that's using VirtualDubMpeg.
