I am bringing long (50 min takes) .mt2 files into Vegas Pro 8.0c from a Canon HV30 (camera mic was a Sennheiser MKE-400). The last two time I have done this, the waveforms display on the audio timeline at the beginning, but later show as a flat line, though the audio is fine and renders are fine (volume is consistent, audio gain was not adjusted on the camera. I just can't see the waveforms on the timeline. I've brought in takes this long lots of times before with no problems, just has happened the last two times.
The first one "flatlines" at 20 min in, and the second one at 13 min in. I didn't see anything wierd happening when the peaks were being built. I tried deleting the sfk file and letting the peaks rebuild, but the result was the same. If I open the audio in Sound Forge from the Vegas menu, peaks show for the whole timeline (but the audio is being rendered to WAV for opening in SF).
OS is XP Pro with all updates, platform is a Lenovo T61. I still have 34 GB free on the capture drive, the OS drive has 6.5 GB free on it. Here's a link to a screen grab of the Vegas screen showing the problem (the second audio track is audio from a Sony D50):
Thanks for any help.
