Loss of audio between clips

Hi Kris, I am unsure whether this issue you are facing is the same as mine, but it might pay to check out the thread I started yesterday: https://forums.creativecow.net/thread/24/975382

Thanks, Ryan!

Hi Kris;

Not sure if this applies to your situation, but a similar problem can happen when a long camera shoot produces files that are larger than 4GB, causing the camera to split the video into multiple files. When those files and dropped into the Vegas timeline, there will be a sub-second gap in the audio between the events. This is particularly maddening when shooting classical music performances.

I deal with this routinely with my Panny GH3, which does not come with any software to seamlessly join long cam video into a single file.

The fix is to use Windows copy to concatenate the files into a single binary file, i.e.

copy /B file-1 + file-2 … +file-n result

When I do that, there is no gap in audio.

Greater minds than I have commented that this has something to do with the events not ending on proper GOP boundaries, but I never understood those details.

One other thing to look at is quantized vs unquantized events – again, not sure if this applies in your case. There is a hidden menu in Vegas which when enabled will display the unquantized event boundaries with red highlights. I change this from the default to TRUE because I want to be able to know when I have unquantized events.

To get to it, select Options, then hold the Shift key when clicking on Preferences.
