user1901: I'm having major issues combining/merging(lossless) swf video files into a single file then converting to something more useful(mp4).
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. 

user1802: One possible solution is: SQUARED 5 MPEG STREAMCLIP it's a freeware converter with basic editing functions. The Batch function should help you.
Other possible software solution: AviDemux
