Body: <p>one question that currently drives me crazy. I used the following command to cut a video:</p>
  <pre><code>ffmpeg -i origin.mp4 -ss 00:09:53 -to 00:11:53 -async 1 output.mp4
  </code></pre>
  <p>However, the output does not start at 09 minutes and 53 seconds, but <strong>at 10:38</strong> of the original mp4. The length (2 minutes) is correct in the output... I don't get the problem.
  Any ideas?</p>
  <p>Thank you!</p>

Comments.Text: that's very strange. Have you tried this on a different file? Maybe the mp4 is corrupted and thus displays a wrong timecode... or could it be that there is a timecode already embedded, starting at 2:00 ?

Comments.Text: I checked the input file and it has a strange behaviour: It starts at 00:00 and after two seconds it jumps to 00:23. And, if I open it with a different media player, it skips the first 40 seconds... strange. Can I repair that with ffmpeg?

  one question that currently drives me crazy. I used the following command to cut a video:
  
  ```
  ffmpeg -i origin.mp4 -ss 00:09:53 -to 00:11:53 -async 1 output.mp4
  
  ```
  
  However, the output does not start at 09 minutes and 53 seconds, but **at 10:38** of the original mp4. The length (2 minutes) is correct in the output... I don't get the problem.
  Any ideas?
  
  Thank you!
