Audio preview problem

[Guest]

I'm synching live concert footage to CD recordings 'cause the live sound was
too distorted. The problem is if I start from the beginning of the video
where the audio starts it's fine but if I find a spot in the video that I
need to fix to synch with the imported mp3 audio and pause it,move the marker
around and try to restart from that section the audio is completely off. I
have to keep restarting the video all the way from the beginning to see if I
made the right adjustment in the right place. This is very painstaking and
time consuming. I didn't have this promblem when I made my last music video.
Is it because it's an mp3 recording and not straight from the CD this time?
What's going on and how to I fix it?

Help! I'm on a deadline. Anybody have any answers? Let me know if I wasn't
clear in my previous post. The mp3 is of variable bit rate if that makes any
difference.

some users run into problems with MP3 files.... converting them to WAV or
WMA before using could resolve your issues.

Thanks PapaJohn that seems to have done the trick. I guess my suspicions were
right. You rock. )

 

[PapaJohn]

thanks... hope you make your deadline!!!

I hope so to. Now I have another issue. I figure I'll put it in this thread
to start in case it's related to the previous issue.
Everything was going find since I made the audio change to .wav but now I'm
almost at the very end of the video...just about 20-30 seconds and the band
is playing a lot faster than the CD track so I have to keep making cuts in
the video, copying a small section and pasting it a few time to stretch it
out to fit the CD track and all of sudden now if I make a cut the player
stops playing at that splice and goes back to the beginning. Now what's going
on? (I wish movie maker had a time stretch tool.) So close but yet so far....

could be having to do with your source video files not working well in Movie
Maker, as your MP3's didn't.

you mention you're using live concert footage... if MPEG-2 or Divx/Xvid
encoded AVI files... it could be the reason. Those kinds of compressed files
have a full frame of info only at key-frames (every so often) and splitting
between key-frames could be problematic.. converting such files is needed to
avoid such issues.

They are .avi files from my Sony DV camcorder.

Well, I set this aside and finished some other stuff and am back with this
mess now. I brought this video file into SUPER to see what the .avi container
had and the video is RGB and the audio PCM. I'm confused by the RGB. I've
never seen this for a codec. I have a Sony DV Handycam and brought the video
in with USB using the picuture package software that came with the camera. So
is this the problem. RGB a codec to start with and what's the deal with RGB
as a codec?

 

[PapaJohn]

Using GSpot to see what codecs and filters are on my laptop... 14 of them
are RGB24, RGB32, or RGB8 formats.... including 3 of them associated with
Movie Maker 1 and 2.

Beyond that, I don't know what that really means.

RGB , red green blue and the number is the number of pixels allocated, so
rgb24 is 8 green 8 red 8 blue, I do believe.

 

[Graham Hughes]

That should be bits allocated per pixel.
