In a previous post, I discussed ways to find subtitles to add to your AVI movies and I also looked at using Google Translate to modify them if they weren't in English (or your chosen language). Note: All of the software mentioned here is free. See: Finding and Adjusting Subtitles on AVI Files . In this post I want to look at how to change the timing on subtitles. Why would you need to do this? Movies have different frame rates depending upon the country that they are shown in and the system they are shown on. Common frame rates are 23, 25 and 29 frames per second. You'd be surprised how quickly subtitles can get out of whack if they're designed for the wrong frame rate. Find the Start and End of the Dialogue. Open your movie in a player, like the excellent VideoLAN (VLC Media Player) and locate the first and last sentences in the movie. You'll find the time in the bottom right hand corner of the player - make a note of it. Adjusting the Subtitle File
