I think currently the assumption is that the project by default would be a multi speaker environment very podcast oriented where each track contains its own audio. However there might be cases where its just multiple camera angles of the same scenario where audio tracks may be used as backup or to sync feeds. Descript pops this message about microphone bleed but instead of just that message it should say is it bleed or do you want to use it for synching sources. That would increase functionality. I have not found a way just to click on the source i want to show. Like just letting the video play and click on track 1 2 or 3 to say which camera angle I want shown. It seems that i need to go inside the sequence an manually make cutouts of what i whant out and what i want shown. The only multitrack instructional video I have found assumes a podcast scenario.
