Frequently Asked Questions
What is an SRT file?
An SRT (SubRip Subtitle) file is a plain-text file that contains subtitle text along with the start and end timestamps indicating when each line should appear on screen.
How do I fix subtitles that get progressively worse?
A constant offset can be corrected here. Progressive drift usually comes from a framerate mismatch such as 23.976 FPS to 25 FPS and needs a linear timing conversion.
