Works with FCPX export

My need was specific - I had a short production in FCPX into which I had imported a .scc file from a transcription service. But I had 4 versions of the video: each the same except for a different 1 minute ending for each. I needed an .srt file for the client for their use on Facebook.

Rather than pay the transcription service to do each separately, in FCPX I was able to copy and paste the caption file that was the same to each variation, add the captions for the short custom ending, then export an .itt file from FCPX.

This app opened the .itt file, then flawlessly converted it to .srt. I renamed the file name to meet Facebook requirements, and it was ready to go.

I had spent an hour searching for a solution, and not even my transcription service could offer a solution other than re-doing the same captioning work mulitple times.

SRT Converter worked for me.

If you do subtitles, you probably need this app

Reported a small bug and the developer IMMEDIATELY got an update out the door! Spectacular customer service.

I use SimonSays AI CC transcription service which only outputs SRT and needed to convert to SMI for my client. This app solved my problem. And I’m set to convert to an insane number of other CC formats.

A useful tool that works great at a reasonable price with a responsive developer - what more can you ask for?

Top Notch Service

I needed to convert several TXT files to SRT files and figured this would be the program to do it. I emailed the developer and they showed me how it could be done. I had several issues, but all of them were quickly address by the developer!
