title: Using ffmpeg to overlay dvdsub subtitles
body: <p>I am trying to overlay a dvdsub file pair (*.idx + *.sub) to a video file.</p>
  
  <p><a href="http://www.filedropper.com/mysub" rel="nofollow noreferrer">Here is the sub pair.</a></p>
  
  <p>This is the batch script with the command line I am trying to use:</p>
  
  <pre><code>@echo off
  set srcVidFile1="myvideo.mov"
  set srcSubFile=mysub.sub
  set srcIdxFile=mysub.idx
  set destFile=D:\testsub.mp4
  
  ffmpeg.exe -i %srcVidFile1% -i %srcSubFile% -i %srcIdxFile% 
      -filter_complex "[0:v][1:s]overlay" -c:s dvdsub -c:v 
      libx264 -crf 24 -c:a aac -b:a 160K -ar 48K -strict -2 -y 
      %destFile%
  </code></pre>
  
  <p>This however only accepts 720x576 VOBsub files. And also the color gets inverted.</p>
  
  <p>My video however is 1080p and do have a 1920x1080 VOBsub file pair, but when I trying use them, I get an error <strong>sub2video: rectange (xxx xxx xxx xxx) overflowing 720 576</strong></p>
  
  <p>Looks like adding <code>-canvas_size 1920x1080</code> before <code>-i %srcSubFile%</code> handles the error on the canvas size. But I can't figure out the color.</p>
  
  <p>The full output: </p>

  <p>I would like to input the 1920x1080 VOBsub file pair and overlay it on the 1080p video with 24bit original colors.</p>
  
  <p>Can somebody give me the correct command line for this?</p>
  
  <p>And as it seems that the VOBsub are low res, is there any means that allow overlaying 1920x1080 24 bit pngs using ffmpeg?</p>
