If you've got some MTS AVCHD files from a Sony, Canon or Panasonic camcorder, you want to open in a program that doesn't support them, like After Effects, then you're going to have to convert them to a different format. Here's a way to convert MTS to After Effects without losing the quality.
Although Adobe claimed that After Effects CS5 and above offer much better native AVCHD support than its predecessor, there are still some video, audio codec problems while importing/editing AVCHD MTS clips in After Effects (AE CC/CS6 included).
