I agree that this is a good method of resetting the times of multi-part subtitles - but If you join the two part video and the two part subtitles then display them together in
SubTitle Workshop, syncing up is easier.
It always seems that with joined videos, the second set of subtitles never quite sync up.
What I do is, append cd1 and cd2 with
VirtualDub (Direct Stream Copy).
Start Subtitle Workshop; choose 'Tools', 'Join Subtitles' and 'Add' the .srt files (in the correct order).
Set the output format.
Check boxes, 'Load file after joining and saving' and 'Recalculate time values' then click 'Join'.
Note that if the new combined file has the same name as the combined movie, the movie will load automatically.
So, if required, load the movie in
Subtitle Workshop. ('Movie' 'Open').
Pause the movie and use the slider to get to the point in the second half where the dialog and subs should start.
Note the time stamp of the video on the right side of the window.
Play the movie if required and pause at the instant where the dialog starts.
When the movie is paused at the correct time (shown on the screen) scroll down the subs listing to where dialog should start.
Assuming that the sync is off, highlight the first unsynced
sub, press 'Shift' and click the last sub.
An example might be sub #637 is the first sub out of sync and the last sub is #1234.
All these subs should now be highlighted.
Start the movie playing again and as the dialog starts, press the 'Move Subtitle' button and the first highlighted sub takes the timestamp of the video.
All of the highlighted subs also have had their times reset.
Test the subs sync by playing the video and save the subs.
