We've produced a video and now need subtitling. You will need to view it on YouTube and transcribe it time codes to .srt format. Then use one of the free online services to convert the SRT to valid xml for another version of the closed captions.
This 5 minute 30 second video is clearly spoken, well recorded and easy to understand English.
You will need to have experience of writing srt & xml subtitles; I don't want to have to iterate this work with you because your titles are too long for the screen or the words are inaccurately placed. Maximum 1 1/2 lines for each caption / maximum 1 caption every 2 seconds.
unrelated srt example:
00:00:20,000 --> 00:00:24,400
Altocumulus clouds occur between six thousand
00:00:24,600 --> 00:00:27,800
and twenty thousand feet above ground level.
