Weird issue I came across today. We've been working on a television episode that has a combination of 23.98 footage and 29.97 (basically documentary interviews and archival). We edited the footage in a 29.97 drop-frame timeline (our deliverable requirement for broadcast) and timed everything out. However, when we go to export a reference quicktime, that quicktime is 1 second and 8 frames longer than the sequence. (Sequence length is 21:10:01 and the quicktime times out to 21:11:09).
