How is the external connected?
Thank you. I read the posts you provided. I thought I had been detailed enough, as I know the more info the better, but I don't know what all might be important to add to this.
It is an external 7200 rpm hard drive connected to an Apple i5 MacBook Pro, external LCD monitor, using an Express card adapter for eSata connectivity. The set up was working before, and I have had 3 days 7.5 hours of final footage) edited with no problem. The second half sounds like the audio doesn't import at the same speed or something so it only plays/shows partial audio. If I play the clip in either the time line or in the preview clip monitor window, I get perfect video flow, but the audio begins to skip and seems to clip elements out of the audio. When you look at the clip in the audio window to see the wave forms, about half way through the clip the audio wave flat lines, and is silent.
I know in the original .mp4 file in the BPAV folder, when played in VLC plays just fine, so it is somehow not importing properly. Since previous files edited correctly, I am stumped.
One thing I have not done is a complete reboot of the system, so I will try that and report back. Perhaps it is an issue with the system somehow.
I am sensitive to wasting people's tome with lame questions and don't post here unless I've tried my best to solve on my own.
