Answers.Text: I'm using WinFF to first convert to mpg then copy /b to combine and streamclip to fix the timebreaks. With WinFF I just have to drag and drop all the swf files and let it go(i.e., batch). Only one that seems to properly convert the swf files.

Answers.Body: <p>The first thing you need to accomplish is to extract the video from the SWF. A SWF is not a video file. It is an application or small program. There is an "FLV video" compiled into it. Try <a href="http://www.sothink.com/page/swf-decompiler/extract-flv.htm" rel="nofollow">SWF Decompiler</a>. It might be able to extract the FLV from the SWF.</p>
  
  <p>Once you have the FLV (the actual video file), there are numerous video editors that can read and edit it.</p>

Body: <p>I'm having major issues combining/merging(lossless) swf video files into a single file then converting to something more useful(mp4).</p>
  
  <p>I've tried using premiere but no audio as it doesn't import the audio. I have many of these files(hundreds) and need a simple way to merge them and convert. I don't really want to convert these files then merge then convert as they are already low quality and they don't need any more artifacts. </p>
