Problems Rendering from DV-AVI Files

I've got a new work-around the severe audio/sync issues with DV-AVI
files.... and am looking for a couple people to test it...

here is fine, or email me at papajohn..... at.... chartermi....dot.... net.
 
Maybe you can help me...

My specific issue - I have captured video to an AVI file, provided by ATI TV
included with the TV Wonder USB 2.0 and updated to the latest version.

I imported this file into WMM (drag-and-drop) and it still played fine from
inside WMM. After dragging the file to the timeline and saving to WMV ("High
quality video (NTSC)"), the audio is now out of sync with the video. My
reason to do so is simply to get a smaller file size (from typical 4-6GB to
typical 1.5-2GB, 720*480*30fps*±2hrs).

My computer is an Athlon XP 1700+ with 1GB RAM and about 50GB free space on
the Windows drive. The OS (XP SP2) is a recent reinstall to correct previous
performance issues (too much stuff installed). (The old stuff has been moved
to different drives, as is most of the stuff I have already recorded.) My
drivers are current. I have DirectX 9.0c, so your reference to KB831937
doesn't apply.

Thanks.
 
I'd suspect the source file not working well with Movie Maker, and convert
it first to something that will... if the avi file is compressed with some
kind of Divx codec, you get issues like that.

Lately I've been using the Panasonic DV codec to make high quality files
from MPEG-2 and other files that need conversion before being used...
there's a link to the Panasonic codec on my Setup > Other Software page...
 
not really as much a template as an approach....

what it involves is simply replacing the DV-AVI source files for the project
with substitutes or fill-ins that might not result in the issues that the
DV-AVI ones do...

the subs are high quality WMV files but named and located exactly where the
DV-AVI source files are... complete with names and extensions.... so
video1.avi gets replaced by video1.avi (but the second one is a renamed
WMV).

Movie Maker only checks the file name and location hasn't changed.... so
when it renders the new movie it'll be pulling info from the WMV instead of
the DV-AVI.
 
A little time consuming with converting/encoding the files but I'll give it
a try and check the results.
 
The solution suggested by PapaJohn was essentially my solution - I saw in a
post / reference (I believe from PapaJohn, incidentally) that AVI does not
sync the audio with the video, hence there are inherent sync issues. (Yes,
the original file was in sync and WMM should have kept it in sync, but that's
another matter...) My capture software allows capture as a WMV9 file as well
as AVI. The WMV file was the same size as the AVI file, but different format.
I then used WMM with the same procedures as before, and had no sync issues
this time.

I generally don't have sync issues except if encoding with TMPGenc
occasionally, not sure why I don't and so many others do, but I copied the
message to my toolbox for future reference and just may do some samples and
tests with the procedure.
