No audio after 1 minute

ANDREMIKE wrote on 3/14/2002, 10:05 PM
I am still using the trial version so I don't know the limitations of it yet...

QUESTION: How come my timeline shows no audio after 1.44minutes? I know there is audio in those frames because I have used it in another software. If I try to expand it I get the littlecarrot on the top and the audio starts from the beginning... I noticed when I first open VF and goto open the file, the description of the file shows audio and video of the same length. When I actually open the file it shows that the Video is 17minutes and the audio is like 1 minute. What hppened?


Another question.... I was also getting a message from VF that it was doing some conversion or something on the audio portion.. I don't remember what it said. I did not let it finish. What was VF doing?

There's your answer. VF was "building peaks" in your audio file. You must let it do that and don't worry... that's a good thing. What it's doing is analyzing the entire audio track and then setting the correct master volume for the track so that the VU meter stays consistent. The end result is a better, smoother audio sound.

VinceG,

I don't think "building peaks" will actually change the audio levels. I think it just builds the graphical representation of the audio so that it can display it on the timeline. It will create a file with an .sfk extension.

You can automatically adjust the peaks by turning on the "Normalize" switch for the audio event.

ANDREMIKE,

Delete the .sfk file with the same name as the video clip, then drag it back to the timeline and allow all the peaks to build. That should give you the full audio.

jimcho-
Yeah, I thought the building peaks feature was normalizing the audio. That's what I was describing. Anyway, I knew that's what was causing Andremike's problem. Thanks for clarifying this.

Ok I did delete the file but for a 17 minute video it only sais there is 1.21 minutes of audio... What happen?

Allright I got more info... VF appears to be creating an AUDIO Proxy file on my captured movie. However it does not finish and i get an error.
WARNING: An error occured while creating a proxy file for a stream.
The format of the stream is not consistant throughout the file.

I can tell you that it dies at 1.21 minutes in. This is where I stopped the recording and then restarted my recording to adifferent scene.

What does all this mean and can I fix it?
The file plays fine in Windows media player....

Anyone have any ideas?

I read on the VW forum that a video captured with VW to create a .avi file will not work right with VF. Is this true? My video was captured with VW.

If its true then I might have to send it back to my camcorder with VW and capture it with VF.

Videowave has been reported to be problematic. More specifically, the VW codec and 1394 drivers can really mess up the _native_ Windows 1394 driver and DV codec, both of which VF relies on. MGI shouldn't be stomping on those components, but they do.

In the ideal scenario, you would save all of your VW media off to tape, remove VW and all MGI/VW components (ALL!), then reinstall VF. I know that sounds extreme, but it may be the only way to get VF to work as designed. Other uses on this forum have done this very thing, and perhaps they can chime in...

Why what other problems might I have? I have heard of people running both.. So far its running ok...except for this one problem. I have a 2 minute file from VW that transferred ok.

CAPTURE QUESTION:
How does VF capture the video? I noticed when I was capturing video it would create a new file everywhere I stopped recording. I guess like this feature although it could wind upto be alot of files for a 1 hour tape. Is there a way to turn this off so it captures in one file?

Under Options, Preferences, Capture, you can turn Enable DV scene detection on and off. Turning it off will make the capture one long file.
