Error: Cannot Load File. It Is Either an Unsupported Media Type or Required Codecs Are Not Found

I used Camtasia Recorder 2018 to capture a webinar so I could watch it later and found that Camtasia Studio couldn't open the resulting large (6GB) TREC file, though it had no problem with shorter TREC files. I was able to read the file in Camtasia after a reboot.

After a completely frustrating experience with tech support that resulted in no new information and random things to try that had nothing to do with the problem, I thought about what might cause this issue and it sounded like an inappropriate file lock issue to me.

So, I recorded another webinar (1 hour and 20 minutes, 17GB file) and once again couldn't open it. I used "What is locking this file," and sure enough, Camtasia Recorder still had it open, though it had completed writing the file several minutes before. 

I shut down Camtasia Recorder, and then Camtasia could open the file.

This seems like bizarre behavior to me. Apparently, sometimes Recorder keeps files locked even when they're fully written. That shouldn't happen. Once the file is written, Camtasia Recorder should release the lock so Camtasia Studio can read it. Every time.

I have asked the tech support person to pass this on to development. Perhaps they will fix it. This is a problem I've seen mentioned on this board over a 7-year period, so then again, maybe not.
