iPad as a video-converter??

Those 'planks' get more and more powerful ...
So, another good reason to tell Santa why I HAVE to have an iPad would be:

Does anybody know of an iOS tool to, say, rewrap mts to mp4? Or rewrap mov to mp4 (no, renaming the suffix doesn't do the trick I need)?

Sort-of MpegStreamclip/ClipWrap/Remux for iOS???


Idea is to 'convert'/rewrap (short!) recordings on the field to share instantly files to users of inferior OSs... without carrying a 'bulky' MacBook ...
no, a full-flavored MBA is NO option, the Secretary of Finance of my household told me ...........
