With a 'low resolution' in the timeline trimming an event with the 4/6 Num-keys sometimes ends up with an event edge not on a frame boundary (PAL project). In auto ripple mode an 'interframe' transition is automatically generated between those two events. This causes the preview of a time loop on this event to show the last frame of the previous event – and certainly will require rendering when exporting the project.
This some times also happens, when a large amount of clips (taken with ScLive) is dragged from the explorer window to the time line.
Can we expect this to be solved in the next release?
