That’s close to the same style Jeff.
I’ve experimented with numerous styles.
The easiest I’ve found it multi-cam, then copy & paste the last clip (some times is 20m long) onto the secondary storyline, & then get rid of it’s audio.
Cut the montage on the secondary, & then cut back to the primary, deleting the remaining 18 minute clip on the secondary. Repeat that 10 seconds later.
It just gets frustrating if you want to come back to different angle on the primary & it isn’t already selected ( changes angles automatically applies to the secondary SL, not the primary).
Plus the clips layered above must be a storyline to become magnetic.
