I received this error while trying to convert an .MTS file to .Mp4 "Error: Unsupported video type or invalid file path" (image here: http://i.imgur.com/P9PqTDh.png)

This was mostly a surprise to me because I had previously converted a few files just before this, all the same file types, and all the same settings, all within the same file folder.

I tried moving the files around to different folders but to no avail. If there's any info that might help me out I would greatly appreciate it.
