Answers.Body: <p>The frame rate is too low for some players. Increase <code>-framerate</code> value or add the <code>-r</code> option. Anything ≥8 should suffice. Example:</p>
  
  <pre><code>ffmpeg -y -framerate 6 -i /storage/apache-j8h3/%d.jpg -i /opt/evercam_media/lib/evercam_media-1.0.1583305674/priv/static/images/evercam-logo-white.png -filter_complex '[1]scale=iw/2:-1[wm];[0][wm]overlay=x=main_w-overlay_w-10:y=main_h-overlay_h-10,format=yuv420p' -c:v h264_nvenc -preset slow -bufsize 1000k -r 12 videotest.mp4
  </code></pre>
  
  <p>In the case above with usage of <code>-r</code> then frames will be duplicated to convert from 6 fps to 12 fps, but it won't be noticeable by the viewer.</p>

  The frame rate is too low for some players. Increase `-framerate` value or add the `-r` option. Anything ≥8 should suffice. Example:
  
  ```
  ffmpeg -y -framerate 6 -i /storage/apache-j8h3/%d.jpg -i /opt/evercam_media/lib/evercam_media-1.0.1583305674/priv/static/images/evercam-logo-white.png -filter_complex '[1]scale=iw/2:-1[wm];[0][wm]overlay=x=main_w-overlay_w-10:y=main_h-overlay_h-10,format=yuv420p' -c:v h264_nvenc -preset slow -bufsize 1000k -r 12 videotest.mp4
  
  ```
  
  In the case above with usage of `-r` then frames will be duplicated to convert from 6 fps to 12 fps, but it won't be noticeable by the viewer.
  
  > **Comments:**
  > **username_0**: can you explain more about -r option?  
  > **username_0**: also I have tested to create a clip with -r 12, it also increases the size of the file without -r it 2.8 mb and with -r its 3.7 mb
