title: FFMPEG Add watermark to MP4
body: <p>I have this command to add watermark to an mp4</p>
  
  <pre><code>ffmpeg -i junai-blvaz.mp4 -i 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" -codec:a copy output.mp4
  </code></pre>
  
  <p>But I am creating the video using </p>
  
  <pre><code>ffmpeg -r 6 -i /tmp/%d.jpg -c:v h264_nvenc -r 6 -preset slow -bufsize 1000k -pix_fmt yuv420p -y junai-blvaz.mp4
  </code></pre>
  
  <p>Is there any way to merge this command of adding watermark</p>
  
  <pre><code>-i 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'
  </code></pre>
  
  <p>to the very first command through which mp4 video has been created? </p>
