The disc layout had to be done manually (“Automatic Layout failed to find a suitable location to place the layer break”), so I set the layer break 1 hour and 4 minutes into the movie, which is a long way from the branch point just 2 minutes in. It is 100% seamless in PowerDVD and also on my LG player, which is good enough for me.
Meanwhile I still haven’t resolved the subtitle sync problem. If you are just joining us, this is the story so far. Using Jubler, each .srt file (taken directly from project Threepio) was split in to two parts (Before the flyover and after the flyover). Also in Jubler, I retimed the second part, so that it counts up from 00:00:00.000 instead of 00:02:26.xxx and verified that they stay in sync from start to finish. That’s all good. Now, since I can’t just import .srt files, I then converted them using Lemony to the correct format, and checking the xml file it created (along with thousands of .png subtitle image files) I have verified that the timing is still correct, in that the in and out timecodes match their .srt counterparts. So far, so good.
Now when I import the BDN files into the authoring software, it asks me if they are drop or non-drop, and regardless of which option I pick, they still drift out of sync.
As I understand it, the original .srt files are timed to match a true 23.976 timecode, but the film is almost certainly using a 24 fps timecode, which is why they slowly drift out of sync. (Excellent explanation of all this here: https://forums.creativecow.net/thread/279/1230).
It sounded to me like the solution should be to convert the timing to match, so, using Lemony, I tried adding a frame rate conversion (23.976 to 24) and rebuilt everything. (It takes about 5 minutes to convert the subtitles, another 2 or 3 to import them, and then about an hour to rebuild the disc before I can test it, so it’s a time consuming process!)
It still goes out of sync (though at a different rate than before) and this is regardless of whether I select drop or non-drop on import or mark the film as drop or non-drop (I think I’ve tried all combinations). At this point I am struggling to wrap my tiny brain around the problem. Any ideas?
