Audio Capture Problem

[Max Baker]

I am trying to capture HDV from my HD100 to Premiere Pro 2. The video captures perfectly (all 56 minutes), but the audio will only capture about two minutes. I'm thinking this may be a simple software switch somewhere, but I haven't found a thing that looks like it may apply. Anyone have any ideas as to why my audio will only capture about two minutes then cease (and go into a loop)?

Many thanks!
Max.

Your description sounds like something I've encountered recently in Premiere Pro 1.5.1., but it's only temporary for me. Let me explain and perhaps you'll notice the same thing.

I use Premiere Pro and CineForm's AspectHD. When I place a long clip on the timeline and try to play it back immediately, everything plays normally for a few minutes and then the sound starts to loop over a 1-2 second segment (like when a record skips.)

I also notice at this point that the waveform display in the audio track is incomplete. (There are gaps with no waveform.) If I stop playback and watch, the incomplete waveform moves around as if it's sliding back and forth, redrawing itself.

Now, if I wait long enough (a few minutes, but seems to depend on the length of the clip), the drawing of the waveform eventually stops. At that point, if I play the clip, everything works fine -- audio is properly in sync from beginning to end.

I believe this has something to do with PPro's audio conforming. It may be creating a proxy file or some other reference in memory, and longer clips temporarily "overload" it until it's done.

So, I have a feeling your issue is the same. Rather than a capture problem, it's probably a playback lag. You might have to wait a while for the conforming to finish if your project is one long 56-minute clip.
