The program works with subtitles in format SRT. 
Insert into a text field the text of the subtitles which are a subject displacement, enter size of displacement in milliseconds and press plus or a minus, depending on a direction of displacement. 
If it is necessary to make selective displacement in the set range, take advantage of a field, placed hardly below.
