I found a couple of things i would like to wish for. A highpass filter or audio mixer on output with an aditional audio source. Or taking the sound from a camera / source that is not rendered.
What i would like to do is to use a camera with external mic as recorder and use the camera to sync up the sound with the rest of the pano cams. So if i could take the sound off a camera without it affecting the stichup prosess, or being able to add a audio track as a last step or something.
