Touch Typing 74WPM allows me to make a transcription with timestamps in a 1:3 ratio (1 minute of video = 3 minutes of work on transcription). This allows me to finish projects in due time, and even before the deadline. If you require built-in subtitles - I can use camtasia to provide your video with this type of transcription. If you have a audio interview or podcast, which you want to publish on your website with subtitles - that is possible as well. A video in camtasia can be made, with use of picture(s) and the audio you have, plus captions on top.
