SRT (SubRip) and WebVTT. SRT uses HH:MM:SS,mmm timestamps while WebVTT uses HH:MM:SS.mmm; the shift routine keeps the original separator so the output stays in the same format.

How do I figure out the right time shift?

What filler words does the cleaner remove?

The curated list covers English ("uh", "um") and Turkish ("yani", "şey", "ııı", "eee"). The match is case-insensitive and removes the word plus any double spaces left behind, so the cleaned text reads naturally.
