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:
- Search/Replace: FIND = 
\R(?!\d{2}:\d{2}:\d{2})REPLACE =☺SEARCH MODE = regular expression, REPLACE ALL => this will turn your data into00:03:26,487 --> 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.☺ ... - Insert a smiley at the beginning of each line: FIND = 
^REPLACE =☺SEARCH MODE = regular expression, REPLACE ALL - 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:- Click in the upper-left corner of the modified document
 - Edit > Begin/End Select
 Ctrl+Endto get to the end of the documentAlt+leftClickto the left of the first character on the last line- You should now have a column selection to the left of the first column of data: 

 
 - ⦿ Edit > Column Editor
- Number to Insert
 - Initial Number: 
1 - Increase By: 
1 
 - Convert the smilies back to newlines: FIND = 
☺REPLACE =\r\nSEARCH 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 - Search/Replace: FIND =

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.
