0003158: Confusion about minimum gap between subtitles (opens in new tab)

When Bv2.1 says there should be "a minimum of 2 frames between subtitle instances" does that mean: * two clear frames? e.g. one subtitle ends at 1, next starts at 4 so there are two unoccupied frames * a difference in time of 2? e.g. one subtitle ends at 1, next starts at 3 I'm not sure. In the git repo are some test DCPs which maybe someone could try on EasyDCP.
