[RESOLVED] Incorrect subtitle timestamps
Posted: Tue Oct 29, 2019 9:17 am
Hello. I am not sure this is an issue with DGIndexNV, but it appears that way, best I can tell. I'm having a trouble where the demuxed subtitle tracks seem to use an incorrect framerate. I've checked the SUP file with BDSup2Sub, and the timestamps are not in sync with the dialogues (well, the sync drift further and further as if the subtitle track was playing at a slower framerate).
First subtitle is marked at 1.919 (about right) and the last at 41:04.256 (should be around 39:23.5 according to the M2TS, which has no such issue). This issue is present on all 5 M2TS streams of this BluRay. After some math it looks like the subtitle are extracted as 23.976 fps instead of 25.
I've cut a sample from one of the M2TS https://mega.nz/#!l9wFwYZI!bfRKFCnpCzLd ... SjHHLcuE0s
