Kirk's Caption Converter

How Caption Converter Works

paste your text in the area below to convert it
you can paste in SRT or WebVTT formatted text, or text with or without extra line breaks, the system will convert any of these
the results will be displayed in multiple formats
you can copy/paste the text shown in the browser or use the "Copy text" button for quicker use
the page replaces your line counter with a calculated line counter
the calculated timings option attempts to guess at the times by multiply each vowel in the line by .3
for accessibility reasons, captions should be 3 to 7 seconds or no more than 3 lines per caption
the "starting time" is
shown like this
if it
overlaps
the end time from the previous line
the "to time" is
shown like this
if it is longer than
7
seconds
the "to time" is
shown like this
if it is less than
3
seconds
you can add time between lines by putting a plus sign and then a whole number (i.e. +5 adds 5 seconds)
you can remove time between lines by putting a minus sign and then a whole number (i.e. -5 removes 5 seconds)
adding and removing time applies to the SRT with original timings and WebVTT with original timings options
lines that start with a left parenthesis like "(" are skipped
lines containing web addresses that are not longer than 7 seconds are calculated at 6 seconds
even if you don't use the calculated timings, they can be helpful to see if a line might be too long
the width of the text area can be used to help gage how long a line should be
there is support for adding " line:##" (use 0 through 15) to allow for repositioning captions to higher one the screen
