When AIP is toggled, the marker pause timings are not updated. For example, if your first marker is at 1min and AIP is off, then the pause should be 0:00:00. But if you activate AIP the pause should indicate 0:01:00, but it does not always do that. If you render a DDP, the pause will be incorporated even though the parent montage timings indicated 0:00:00. This lack of up-to-date timing indication is confusing. In WL5, AIP modified timings were updated/indicated instantly.
Besides the desire of expected accuracy, having correct timings gave an additional clue whether AIP was on or off. Often AIP is on when you don’t really want/intend to use it. The visual indication for AIP state is tiny and easily overlooked in a sea of buttons. Having accurate, up-to-date timing indication provided another clue of AIP state and helped avoid mistakes when rendering.
