Waveforns not showing in all of timeline

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.

I am having the same problem. No waveforms show up in trimmer on the last 10 clips in my project media (although i can hear it). When i drop it into timeline the waveform is not there. nolonemo- did you ever get it resolved?

On all clips I have always had another problem with each clip at the end. There is no waveform for about 1 second and no sound!

Do either of you have anti-virus running on your machine? Try disabling your anti-virus and rebuilding peaks.

On all clips I have always had another problem with each clip at the end. There is no waveform for about 1 second and no sound!

I believe that's a known capture issue. Another user offered a script that would allow you to trim 1 second off the end of all clips. You might find that helpful: http://www.sonycreativesoftware.com/forums/ShowMessage.asp?MessageID=607193&Replies=1

I just wanted to write and say that I, too, am having precisely the same issue. I hope a solution is discovered soon... disabling antivirus for me does nothing. It only occurs with certain files, though I haven't yet been able to isolate the problem.

Perhaps unrelated is the fact that other files (WMVs mostly I believe) cannot be read at all. Dropping them on the timeline results only in a zero-length video item that seemingly can only be removed by undoing the action or removing the item via the Project Media tab. Is there any solution to this?

I am running 9.0a 64-bit. Thanks for the help and this great forum as always.
