Ok so I have a .ttml of timestamps where I analyzed a mp4 video and stripped subtitles. The assumption is that these timestamps are actual audio in the video (basically these timestamps are audio in the video) Here is how the .ttml looks like This sets how many times faster or slower the audio will play. For example, setting this to "2.000" will double the speed (and raise the pitch by one octave), or setting this to "0.500" will halve the playback speed (and lower the pitch by one octave). Values between 0.010 (1/100th of the original speed) and 50.000 (50 times faster) are permitted.
