I was using the 1:01 chapter marker position because a marker that is at 1:00 is already on a COP boundary when the GOP length is 15 frames so it wouldn't have to move to get onto an appropriate GOP frame which to me is what it looks like Encore is doing to me when my marker is at say 1:01. What I am seeing looks like En is encoding my sequence to mpeg2 and then plugging in my chapter makers to the closest possible frames. You can even try this on a sequence that is already encoded. Try adding a chapter marker to a timeline (in En) at time 1:01 or 1:02 or 1:03 and it won't go there. It will jump to a 15-frame boundary. En should be creating I-frames at my chapter points when it transcodes so the chapter markers can be in the correct position in the video. It doesn't seem to do that for me but you're saying it does transcode such chapter markers correctly for you is that right?
