(Before)

00:03:26,487 --> 00:03:28,448
Do you mind the radio?

00:03:29,198 --> 00:03:30,717
Do you want me to turn the radio off?

00:19:07,990 --> 00:19:10,367
Okay. Be a good girl.
Get out and go home.

@Clayton-Lewis ,

search/replace doesn’t have a way of counting, so it’s more complicated than some questions.

If you have the PythonScript plugin, you could write a script that would do it.

However, if you are willing to do a multi-step process, what I might suggest is:

1. Search/Replace: FIND = \R(?!\d{2}:\d{2}:\d{2}) REPLACE = ☺ SEARCH MODE = regular expression, REPLACE ALL => this will turn your data into

   00:03:26,487 --> 00:03:28,448☺Do you mind the radio?☺
   00:03:29,198 --> 00:03:30,717☺Do you want me to turn the radio off?☺
   00:19:07,990 --> 00:19:10,367☺Okay. Be a good girl.☺Get out and go home.☺
   ...
   

2. Insert a smiley at the beginning of each line: FIND = ^ REPLACE = ☺ SEARCH MODE = regular expression, REPLACE ALL
3. Use Column Select mode to select the zero-width first column. The standard way of doing a column select is Alt + Click-and-drag… but if your file is long (and I assume it is), you will want an alternate:this post describes a way to accomplish it:
   1. Click in the upper-left corner of the modified document
   2. Edit > Begin/End Select
   3. Ctrl+End to get to the end of the document
   4. Alt+leftClick to the left of the first character on the last line
   5. You should now have a column selection to the left of the first column of data:
4. ⦿ Edit > Column Editor
   1. Number to Insert
   2. Initial Number: 1
   3. Increase By: 1
5. Convert the smilies back to newlines: FIND = ☺ REPLACE = \r\n SEARCH MODE = regular expression, REPLACE ALL =>

Hope this helps

PS: If you find yourself often wanting to be able to do the begin/end selection in column mode, you can make a macro following instructions in this linked post

Awesome, thank you very much! worked like a charm except for step 3 part 2-4.
Scrolling down to the last line before the first character then holding Shift + Alt did the trick.

You are right. After 3.4, I should have said another Begin/End Selection. Sorry. But yes, what you described is equivalent.
