True the video and sub are from different sources. On the mkv I re-saved and renamed in Toolnix then put these saves into Subsync. Same result.


What Ive done on this just see if it works is use Google AI for the question. The response on that source said likely a corrupt file. But
the video mkv and the audio play fine. I was just looking to get a refined sync which was off enough to make it a pain to read.
What would checking for a file corruption look like?


[edit] I just reloaded a previous jov in Subsync and that worked fine.


I may just use the internal play/start arrows in VLC. ]]> Subtitle loninappleton https://forum.videohelp.com/threads/420869-Using-Subsync-for-subtitles-fails-on-one-title
