Convert TREC to CAMREC

If any program can convert .trec files to .camrec files, it would be Camtasia Studio from which both of these file types originate, albeit from different version of the program. Worth mentioning is that at least some Camtasia files made on Windows and Mac versions seems to be not compatible and you have to open them on their respective platforms. Other than that, it is unlikely you will find a 3rd party program designed for the purpose of trec to camrec conversion.
