Camtasia MP4 Error and Medialooks Watermark Removal

Adrian Video Image has posted a new item, 'Camtasia MP4 Error and Medialooks Watermark Removal'

Something really annoying happened to my Camtasia today. Wasted four hours of productivity just to figure out the solution.

What happened?

A “medialooks” logo appeared out of nowhere and stuck itself on the top left hand corner of all my renders.

I used the same setting I have always been using for the past few months without problem.

How did the “medialooks” logo get there? What did I do wrong? Was it some overlooked settings?

After going through all my Camtasia settings, I cannot find anything that will even turn on the logo.

Googling for the answer, I learnt  that the uninvited “medialooks” logo will appear in videos when there is some kind of QuickTime trial software installed.

Nonsense! I did not install any kind of QuickTime trial programs… wait… I did the regular update of iTunes and QuickTime player 3 days ago.

Then some forum expert suggests uninstalling QuickTime and installing free K-lite codec.  So I followed exactly.

Great! The time-sucking problematic logo is gone.  BUT now, there is a new issue!

Introducing the second problem…

Camtasia cannot detect MP4 video. There is audio but no visual.

What I am doing is use Camtasia to convert an MP4 video rendered from Sony Vegas to another format.

After tweaking K-lite and messing around with the confusing settings, Camtasia still cannot read an MP4 video properly.

What next?

Uninstalled K-lite codec… re-installed QuickTime…

NOW… Camtasia completely cannot accept MP4 files… and always showing codec error message.

Then it hit me… A little voice spoke…telling me what to do.

“Uninstall and re-install Camtasia!”

YES! it worked.

No need K-lite codec at all. Just install QuickTime first then install Camtasia.
