   If anyone else uploads videos to web sites such as Amazon,   
   this summary might help you - thanks to all the help here.   
   a. The process removes personal information   
   b. And it stabilizes jumpy videos   
   c. Plus it adds captions into the video   
      
   This way only a single file is uploaded.   
      
      
   1. Create a copy of your MP4 (just in case)   
       C:\> copy amazon.mp4 amazon1.mp4   
      
   2. Remove metadata (spaces matter in the command below!)   
       C:\> exiftool -all= amazon1.mp4   
      
      (prolly should use ffmpeg for this step)   
      
   3. Test that the metadata was removed   
       Rightclick on the video review > Open With... > Media Info   
      
      (again, prolly should use ffmpeg)   
      
   4. Deshake the video (if needed)   
       C:\> ffmpeg -i amazon1.mp4 -vf deshake amazon2.mp4   
      
   5. Create captions if needed (assume a 68-second video below)   
       C:\> gVim amazon2.srt   
      1   
      00:00:05,000 --> 00:00:15,000   
      I think this product is crummy   
      Because it failed all my tests   
      
      2   
      00:00:20,000 --> 00:00:30,000   
      Even the cat didn't like this product   
      
      3   
      00:00:40,000 --> 00:00:50,000   
      But there was one saving grace   
      
      4   
      00:00:55,000 --> 00:00:68,000   
      The product didn't cost all that much   
      
   6. Merge captions into the file for upload to Amazon   
       C:\> ffmpeg -i amazon2.mp4 -vf subtitles=vine.srt amazon3.mp4   
      
   The result is a single stead(ier) file with burned-in captions.   
   If you can make ALL the steps using ffmpeg, that would be better.
