importing video with more than 2 audio tracks separatly into Vegas 20

21stCenturyStudios wrote on 2/6/2023, 12:58 PM

Having trouble importing multi-channel audio Sony .mxf files or any type of file for that matter with multiple audio tracks on a 5.1 surround project or any stereo project. When the file is imported it only shows up as one regular 2 channel track on the timeline that also seems to sometimes mix t2 audio tracks into just one left/right track. Anybody have a clue???

This should properly import a 5.1 audio stream if the clip contains one. It will be fully explained in a tutorial in a few weeks.
