Join
AVI files with
AVIDemux.
Load the first video, append the second.
The video/audio boxes on the left side of the window should be set for 'Copy' and the output 'AVI'.
Joining the .srt file subtitles.
Run
Subtitle Workshop.
Tools > Join Subtitles
Check the two boxes labeled 'Load file after join' and 'Recalculate time values'.
[it will load the new combined file and reset the values on the second part of the subs]
Click on 'Add' - to load the subtitle files - and click 'Join' and give the joined file a name.
The new combined files will load.
Click 'Movie' and open the movie file and check the subs sync.
If the combined
AVI and the subs are synced, fine.
If not read further.
This assumes the
AVI files are now one file and the .srt files have been previously joined, re-timed, and saved using
Subtitle Workshop, but for some reason the second part is out of sync.
It entails splitting the .srt file again, adjusting the timing, then rejoining the .srt file again.
Run
SubTitle Workshop and load the combined .srt file (the combined AVI loads automatically if it has the same name).
Run the video and note the last line number where subs and video are in sync.
'Tools' > 'Split Subtitle', choose the 'Simple' tab and check 'Item Number' and input the line number.
Note:Do not recalculate time values (uncheck
the box).
Save the files (Click 'Split').
What you have is one .srt with correct times and one .srt with incorrect times.
Load the second (incorrect time) file.
Highlight the first
sub line number.
Play with the video and gauge where the first sub should come in.
Pause and adjust the video at this point and press Ctrl+1 (or the button, third from right, under the video window).
Highlight the last sub and adjust the video to match.
Press Ctrl+2 (or the button, second from right, under the video window).
Set the video back to the first sub, line up the video and check sync.
Either 'Save' or 'Save as' the .srt file.('Subrip' is .srt format).
Now the two files have to be joined.
'Tools' > 'Join Subtitles', add both files, the first split file and the new edited file.
Make sure that the 'Recalculate time values' box is "not" checked before joining.
Reset the video to the beginning, use the slider and check sync.
Remember that the AVI and .srt must have same name.
