How to fix weird subtitles?

[DaveR]

Does anyone know how to fix subtitles that add 2 letters per line? I can't even find what this style of subtitle is called.

I want to change an srt file full of lines like this:

1
00:00:00,767 --> 00:00:00,800
(S                             

2
00:00:00,800 --> 00:00:00,834
(Sil                           

3
00:00:00,834 --> 00:00:00,867
(Silen                         

4
00:00:00,867 --> 00:00:00,900
(Silence                       

5
00:00:00,900 --> 00:00:05,538
(Silence)

to normal lines like this:

1
00:00:00,767 --> 00:00:05,538
(Silence)

I found a solution using Notepad++ and then SubtitleEdit.

Using Find and Replace in Notepad++

1) Remove leading and trailing whitespace.

Find: (^\h+)|(\h+$)
Replace:

2) Remove CC in brackets. For lines like: "Bob: (grunts) I don't know" where the whole line was being deleted in step 3.

Find: \(.*\)
Replace:

3) Remove incomplete progressive subtitle lines.

Find:

^(.*)(?=((\r\n?|\n)(\r\n?|\n)[0-9]+(\r\n?|\n)[0-9]{2}\:[0-9]{2}\:[0-9]{2}\,[0-9]{3}[ ->]{5}[0-9]{2}\:[0-9]{2}\:[0-9]{2}\,[0-9]{3})+)

Replace:

4) Replace 2 spaces with 1 space (left over from step 2).

Find: (\h){2}
Replace: $1

Then in Subtitle Edit

1. Renumber.
2. Merge duplicate lines.
3. Remove SDH.
