    SRT files in AE - a working solution -

      THE ISSUE:

      For a while now I've been seaching for an easy way to add subtitles to my After Effects files. I know there are a few different ways to use free and/or paid extendscripts but the ones I've found all ended up with having hard-coded keyframes. When you've made some manual changes to your subs in AE and there were some last-minute changes to your subs you either had to manually do the corrections, or re-run the script with the new sub and re-do all you manual (formatting) changes.


      Wouldn't it be ideal if you could just import/link the SRT file into your library like you would with other kinds of footage?



      you can!


      Since the CC2018 version of AE you can import JSON files to create data driven animations. Well, isn't a JSON file basically just text? So this got me thinking; "what if I tried importing a SRT file instead of JSON?". As it turns out, if you omit the file mask in the import file dialog (All files (*.*)), you can in fact import *.srt files. Using




      as an expression on a textLayer's Source Text if showed the (complete) contents of the SRT file. All I had to do now is parse the contents, get the in-time, out-time and the actual sub and have it all displayed at the right time. Mind you, I'm not a programmer so there might be a better, more efficient, prettier looking solution than this, but here's my working solution:


      var subFile = "sub.srt";
      var lines = footage(subFile).sourceText.split('\n\r\n');
      for (n = 0; n < lines.length; n++) {
      if (time >= srt(lines, n).start && time < srt(lines, n).end) {
      sourceText = srt(lines, n).sub;
      } else {
      sourceText = "";
      function srt(lines, i) {
      origin = lines[i].split('\n');
      ID = parseInt(origin[0]);
      startText = origin[1].match(/^[0-9][0-9]:[0-9][0-9]:[0-9][0-9],[0-9][0-9][0-9]/)[0].replace(",", ":");
      endText = origin[1].match(/\s[0-9][0-9]:[0-9][0-9]:[0-9][0-9],[0-9][0-9][0-9]/)[0].replace(' ', '').replace(",", ":");
      var subtitle = "";
      for (var j = 2; j < origin.length; j++) {
      subtitle = subtitle + origin[j] + '\n';
      return {id:ID, start:parseTime(startText), end:parseTime(endText), sub:subtitle};
      function parseTime(str) {
      hours = parseInt(str.split(':')[0]);
      minutes = parseInt(str.split(':')[1]);
      seconds = parseInt(str.split(':')[2]);
      millisesconds = parseInt(str.split(':')[3]);
      t = (hours*60*60) + (minutes*60) + seconds + (millisesconds/1000);
      t = Math.round(t*100)/100;
      return t;


      You simply place the above expression in the Source Text property of a TextLayer and replace "sub.srt" with the name of your imported subtitle file.
