Back when I was editing 2 people conversation clips, they'd constantly talk over each other, and doing subtitles drove me insane. Transcripts helped a bit, but not enough. And this was with multiple cameras running too, so I still had to replay the same bit over and over just to figure out who said that.
This week I tried a weird little hack and gave each person a different color mic so I could tell who was taking.
They were using DJI Mic Mini 2, and we put a blue cover on one person and a yellow one on the other. Just kept the same color on each person for the whole shoot. Since the mic comes with 10 color covers, it's pretty easy to switch them out based on what each speaker is wearing.
When I was scrubbing the timeline, I could just glance at the preview and go "blue mic = speaker A, yellow mic = speaker B" instead of replaying the clip again. Sounds like the dumbest little detail, but after captioning a bunch of overlapping dialogue, I'll take any help I can get.
Just want to share this little trick in case it comes in handy.
