Looking for a subtitle format

[Atoon]

I'm looking for a subtitle format that look like this, for using it with a rare piece of software called "Karaoke Video Creator":

00:16.540 00:16.840 On 
00:16.842 00:17.100 a
00:17.102 00:17.360 dark

(Start minute, second and millisecond; ending minute, second and millisecond; words) The most similar I know is the Adobe Encore one.

Alternatively, I may try to use "find / replace" over another kind of file like .srt, but I don't know how to remove some stuff like the "numbers" for each line. I can't use Adobe Encore subtitles as is it as it don't have milliseconds.

Maybe can you use use subtitle edit to export to a custom format.

Open/create your subtitle and then under File->Export->Export custom text format. Click New. Under Text line: use for example

{start} {end} {text}
