Upload a .srt file and define how you want to manipulate it. Copy and paste the result into a text file.
Encoding of .srt file is automatically detected unless specified.
The new times are calculated using the following formula:
newTime = oldTime * scale + delay
A scale less than 1 will squeeze the subtitle into a shorter time period, a scale larger than 1 will spread the subtitle out over a longer time period.
A positive delay means that the text will appear later and a negative delay means that the text will appear earlier.
