• Subtitle word scaling with ASS file causing line shifting

  23 avril 2024, par Barrard

  I'm trying to make my subtitles scale one word at a time, but I'm running into an issue with the whole line shifting.
Is there a way I can scale a word, and make the other words not move sue to the scale effect ?
Here is the ASS File

• Making progress bar with FFmpeg duration value

  11 novembre 2014, par user2978381

  I am mainly a back-end developer. I have rarely used javascript. But for real time update now I have to use javascript, ajax, jquery or something like that.

  My php script outputs this value "100%" at the end of the conversion.

   echo "Progress: " . $progress . "%";

  The $progress variable actually holds numeric data like 10 and I want to use this value for making progress bar. The value of the $progress variable changes every second and I need to capture this value.

  So if I want to implement this value in the following html file what will I do actually ?

  <code class="echappe-js">&lt;script src=&quot;//code.jquery.com/jquery-1.10.2.js&quot;&gt;&lt;/script&gt;
  &lt;script src=&quot;//code.jquery.com/ui/1.11.2/jquery-ui.js&quot;&gt;&lt;/script&gt;
  &lt;script&gt;<br />
  
  $(function() {<br />
  
    var progressbar = $( &quot;#progressbar&quot; ),<br />
  
      progressLabel = $( &quot;.progress-label&quot; );<br />
  
  <br />
  
    progressbar.progressbar({<br />
  
      value: false,<br />
  
      change: function() {<br />
  
        progressLabel.text( progressbar.progressbar( &quot;value&quot; ) + &quot;%&quot; );<br />
  
      },<br />
  
      complete: function() {<br />
  
        progressLabel.text( &quot;Complete!&quot; );<br />
  
      }<br />
  
    });<br />
  
  <br />
  
    function progress() {<br />
  
      var val = progressbar.progressbar( &quot;value&quot; ) || 0;<br />
  
  <br />
  
      progressbar.progressbar( &quot;value&quot;, val + 2 );<br />
  
  <br />
  
      if ( val &lt; 99 ) {<br />
  
        setTimeout( progress, 80 );<br />
  
      }<br />
  
    }<br />
  
  <br />
  
    setTimeout( progress, 2000 );<br />
  
  });<br />
  
  &lt;/script&gt;

• Word-by-word display of subtitles in FFMPEG ?

  10 mars 2020, par ThaDon

  I am trying to burn subtitles into a video such that they appear in a word-by-word fashion instead of all at once.

  What I mean by this is, a word will appear, then another word will appear next to it, and so on. Eventually the line will clear, then repeat.

  Example :

  

  I thought I could create an Advanced Substation Alpha file where subtitles share the same end-time but differing start times, however FFMPEG doesn’t seem to cope very well when rendering the file :

  Dialogue: 0,0:00:01.50,0:00:03.46,Default,,0,0,0,,subtitle

  The idea being that I'm would appear, then 1 second later a would show up next to it followed by subtitle a half second later
