Both .camrec and .tscproj come from Camtasia Studio, but most likely from different versions of the software. Unfortunately, we were not able to determine if direct camrec to tscproj conversion is possible, but it might be a simple matter of importing/opening .camrec files and saving them as new projects.
If you have issues with Camtasia file types, it would be best to contact their support or some online community.
