Lots of problems with sound...

Hi,

i have several problems with sound in Final Cut Pro 6.0.2, i will try and list them all:

1: I had two mp3 soundfiles in my sequence that were on different tracks, and also had a different sample rate (44.1) than than the sequenz (48KHz). So i had to render them, but final cut would not render everything only one part of the overlapping region. The rest stayed unrendered, so i selected the soundfile again and hit "command-r". Now FCP rendered the other part of the region, that was not rendered before, but to my surprise the parts that were rendered fine the first time, now were not renderd at all! Any idea what i can do against that bug. I just cannot render everything...

2. Again i was working in a sequenz and pulled in the soundeffect "Impact Metal.caf" from the SoundtrackPro library. Had to render it, everything fine so far, kept working. But after a while the soundeffect got muted. It was still there in the timeline, but it made no sound. Even deleting the Audio Renderfiles and rendering it again did not work. Any way around this bug?

3. Normal sequenz, with video and sound. Also one sourround effect with surround i guess because it has 6tracks, also from soundtrack Pro. I want to solo one track of the sequence, but its not possible, why not?

4. I load an mp3 file into the sequence that has 44.1 khz as opposed to the 48Khz of the sequence. i render it, everthing is fine. later i grab the and of the soundfile and make it longer. So I have to render the rest of it too. Fine i do it, but now the beggining of the soundfile is different, as if i would have slided it to a different position, which i didnt... Any idea?

I am getting a bit crazy around here, to many bugs..

Any help is greatly appreciated!!!

As a general rule I would avoid using MP3 files, it's just not a great choice for a slew of reasons. But sample rate should not be a problem, FCP should deal with mixed rates. So this may be an MP3 thing.
2, check your volume automation, you may have taken the level down by accident.
3, sounds like you want to solo one of the six channels on the track. I don't think that is possible. And it wouldn't be a bug, they are not separate tracks. What you may be able to do is change the balance so only one is audible. Otherwise if you only need one than convert it in STP to what you need and import it.
4, no idea but again I suspect the MP3, especially if it's a VBR MP3. Use WAV or AIFF files instead.
 
thanks Noiz2, yeah mp3 dont seem to be a good thing for FCP.

2. No the volume on the soundfile was ok...

3: No i tried to solo a track in the sequenz, so that is definitely something that should be possible :)
 
i've experienced the render problems you're encountering. go into the render manager and delete them. then re-render all at once. and if you like, use itunes to convert your audio files to 48khz AIFs.
