MXF video files can contain up to 8 audio tracks. If this is checked, Vegas will import the video and create a separate audio track for each channel. When its unchecked, Vegas will import MXF files as a single stereo track.

Thanks John. I didn't know any of that. How would I go about feeding in more than 2 channels into my 2 channel camera? I'm guessing this format provides for the 8 channels for another device?

I guess that means 7.1?

No, you can have 8 discreete channels of 16/48 audio...or is it 24/48?

To answer Grazie's question, only if the camera supports it.
I know some of the XDCAM cameras support 4 channels recording to XDCAM, I cannot imagine a camera supporting 8, that'd be a lot of XLR connectors and cables.
Outside of cameras though you can use those audio channels for whatever you want and it's a good way to render out vision and audio if you want to leave the final mix for later or someone else to do. Or you can use the channels for alternate dialog.
From memory in Vegas to use those channels you have to setup busses and then in the encoder map the busses to the channels.

IMX MXF or 4:2:2 MXF can have up to 8 channels of 48k/16bit or 4 channels of 48k/24bit audio, all other MXF formats can have 4 channels of 48k16bit.
