Tick, click, glitch: Issue ID'd; still no resolution

[Jeffraham Prestonian]

I think I figured it out, but no solution so far.

My problem (as many others' here, it would seem):
When outputting from WinMovie Maker to DV-AVI, I
would have glitchy audio on clips where I had added
..WAV files in projects. In MY particular instance, I
was adding piano music to a "slideshow" of still photos,
which was a part of a project that also used DV
captured from my Canon GL-1.

Problem identification: I've been using the GL-1 in
the mode which captures audio as 12-bit. Dammit.
:-/ Using both 12-bit and 16-bit (.WAV) audio files
in WinMovie Maker, and saving as DV-AVI (or WMV,
or... probably anything) isn't going to work well. My
guess is that WMM tries to resample the 16-bit audio
at 12-bit resolution, adding the glitches and artifacts.

I can see that saving off the audio portion of the
WMM project and adding it back in might work, but
since I have, basically, two tracks of audio, and no
good way to synch them, I think that's a wash for
me. I tried the "audio only" route, but can'y save as
anything but WMA, and my audio editors won't
recognize them. Sigh.

Hello,

That's a well known problem. Movie Maker is not very good in a few areas....re
sampling a still image and re-sampling an audio file....the standard for DV-AVI
is 16bit audio, and I guess they made it the standard for WMV from MM as well.
The result of that is that they do not need to resample the audio...its down to
you to do that, or record using 16bit audio in the first place.

A very good and free program for editing audio is called AUDACITY. There is a
link to it on my website.

Not well enough for me, but that's MY fault...!
Actually, I knew mixing bit resolutions on audio is a
no-no, but when I was shooting the footage, I never
*dreamed* the GL-1's default audio rate would be
12-bit. I poked around for info on an editor that
might be able to resample from 16-bit to 12, but no
dice. If I had time (which I don't) and if I had
something like Premiere (ditto), I'd resample all the
cam's audio up to 16-bit, and re-synch it with the
project. There's a lot of V.O. and added music tracks
in this particular project, and I need it done by
Saturday morning. So, I guess we can live with the
pops and glitches this time. At least I know what to
do before the next shoot...!

Hello again,

Actualy the default on my Canon was 12bit. I changed it to 16bit and never
bothered to chang it back...as a result my first dv video came out ok....all
Luck...No Judgement involved

Anyway, best of luck with it.

If you can save a good WMA then do this:

1. Output DV AVI
2. Out WMA from same project
3. Combine the outputs of 1 and 2 in another project, muting DV AVI's bad
audio.

Can't save a good WMA -- it has the same glitches that
the DV-AVI and the WMV versions had. The good news
is, the "client" (friend, wanting to do a tribute vid for his
parents' 50th anniversary) is overjoyed, even with the
pops and clicks.
