subtitles slightly (!) after spoken word

Post by dff.ffm »

Hi there,
do have a srt-file; after adding to dcpomatic subs appear at screen let's say 50-80 ms delayed.
My approach would be to set starting time of added mkv some frames later. 3 or 4.
Am I doing something wrong?
regards - TG

How are you checking the sync?

a) with embedded player.
b) on Sony 510.
both show a very slightly delayed sub.

OK, how did you check that the .srt file timings are right with respect to the MKV file?

Does the sync stay constantly the same amount out, or get worse?

Near the end, difference between subs and spoken word is slightly larger. 110 min. movie from a japanese dvd.

... could it be the 29,97/30 difference?

Could be, but DCP-o-matic is supposed to cope with that. I'll do some tests here.
