Audio drop

Rosebud wrote on 4/10/2004, 12:04 PM

Hi,
Sometimes i get audio drop when capturing over firewire (PAL DV).
The audio drop length is exactly one frame (there is no drop with frame).
See screenshot :

Generally, i get 1 or 2 drop for 10mn of movie capture.
If i recapture, audio drop disappear.

Any idea to solve this problem ?
Thx for your help

I'd be looking to the camera. Can you try another? If it repeats on multiple systems, and the video doesn't drop any information, sounds like a camera issue. Since audio and video are a single file in Vegas, even though it's a type 2 cap, if one drops so should the other.

Thank for your help Spot,

I have audio drop with both camera (TRV900 & TRV120).
I made a test with ScenalyzerLive and I don’t have any drop (1 hour capture length).

And you're using 48k/16 bit? Or is your audio 4 channel, 32bit/12k?

I’m using 48K/16bits.
