Camtasia needs to accept AVCHD files. All the workarounds suggested by the support team don’t work. It's not resolved. I tried everything recommended in the link sent by the tech agent and nothing worked. I've decided to switch to a different video editing software. Handbreak didn't work. YOU need to make Camtasia accept mov files and AVCHD files. It shouldn't be the user's job to do all this file transformation to make YOUR software work. I'm using Wondershare Filmore. It works right away. Give this feedback to your software developers. I like the Camtasia platform, but can't use it if it doesn't read standard video files.
