What is going on here...  The ensharpen codec is supposed to come with Camtasia, and there is no way to "buy" it that I can see...

Didn't work for me..going to try avi and then re-encode...annoying because the mp4 codec has been changed so the file size is much smaller and blurrier.

I'm sorry, but the reply from Joe was not helpful at all. I have already followed the instructions in the link he provided, that is why I was able to render an MOV-file in the first place. The issue I and a few others are having is that we already have the newest version of Quicktime and the Ensharpen codec installed, and we ARE able to produce Ensharpen MOVs, but they render with an evaluation stamp. I am using a licensed version of Camtasia, so there is no reason for the evaluation stamp to show up. What can I do to render an MOV without the evaluation stamp? (I am using Camtasia on Windows, btw)

I would contact Tech Support.
 This question came up again a couple of weeks ago and I tested it on my computer and encountered the same problem.
I told that poster to contact tech support as well. I don't know if they resolved the issue or not. I don't render videos to .mov so I didn't pursue the issue myself.

Thanks Joe, will do. Let's hope tech support gets back to us, the video quality I got using Ensharpen was superior to anything else, so I would love to get rendering working without the stamp.

I replied to Marita in the Support ticket she submitted but thought posting the solution here would help as well.

Open the registry and browse here.HEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\TechSmith\CamtasiaStudio\8.0

In that 8.0 folder create a key called "RegisteredTo" and have the string value be your name.
Then create a key called "RegistrationKey" and set the string value to your software key.  It should look like this.

That should get rid of the watermark.  Hope this helps!

Thanks Mike,
That fixes it alright. I'll probably never use it but it works.

Modifying the registry is not for the faint of heart or the inexperienced in my opinion.
I think it would be much better if TechSmith created an executable patch for anyone who needs it. The customer shouldn't be asked to modify the registry at all.

If nothing else create an official TechSmith instructive video showing every step in detail.

Regards, Joe

Thanks Mike, I managed to get rid of the stamp by following the instructions you gave me. I haven't edited the Windows registry before, so that was new to me, but I didn't find it particularly difficult (then again, my company works with PKI so I am fairly familiar with the concept of keys and user access rights). I agree with Joe that a patch might be a better option for users who aren't as computer savvy, but this was still a quick fix for my problem. Thank you for your help and your speedy reply.
