I am just starting to explore Active Track and associated Focus Track options. In my attempt to do so today I got the message Focus Track not supported in current recording format/shooting mode. I was filming in .mov (tried mp4 too), Normal (not dlog). I was not in Tele, it was normal video mode and I tried to draw a square around a person walking while I was filming and when I was not filming. I kept getting the same message. Any idea what I was doing wrong?
