crackling sound with mpgs

[mikeny]

I have 2 questions.

1. Can anyone suggest a reason why every mpg capturing program I use produces sound with a static quality? I've tried Intervideo WinDV Creator, Sonic MyDVD, and Ulead MovieFactory3.

I always turn down the volume on the speakers and in the "master volume-Line In" from the system tray.

Any advice on this persistent crackling, staticky noise from captured .mpgs would be greatly appreciated

Oddly enough, when I use WinDV the transferred .avis are fine. Likewise, when I encode them with TmpgEnc Plus, the .mpgs are ultimately fine. Although I'm pleased with those results, its quite time consuming, especially the step where I append a million .avis and resave with VirtualDub which I do so that I don't have a million mpg clips on a DVD.

2. Is there a way to make WinDV transfer files in a way where it doesn't break it up into 1 .avi per clip? By clip, I mean pressing record for 16 seconds and then stopping.

Thanks,

Mike

Set the discontinuity threshold to 0 ? I think that's it.

If you can stand the extra time for encoding, this is always going to be the way to go quality-wise vs. realtime software mpeg encoding.

The crackling on your sound may be on one of the inputs to your sound card. Try turning off all inputs in the record mixer settings.

Just to clarify, your source is from a DV cam via firewire?

If so, check the audio settings on the camera. If it is set to 12 bit or 32khz, change it to 16 bit or 48khz. The crackling may be cause by poor upsampling from 32khz to the 48khz needed for DVD. Obviously TmpGenc is doing a decent job where the other apps that convert to mpg in real-time (during capture) are not. Changing the setting on the camera will solve this problem for the future but not for existing DV tapes. For those, stick with TmpGenc for encoding.

EDIT, BTW, TmpGenc will take multiple avi files as input and encode a single mpg. The files must be named something like file001.avi, file002.avi etc. There is a setting for this somewhere in the environmental settings.
