With Apple's decision to no longer support updates to QuickTime on Windows the US government posted the following announcement advising users to uninstall the QuickTime software.
Q: Will Camtasia still run if I uninstall QuickTime?
Q: Does TechSmith recommend I uninstall the QuickTime software?
A: Yes, to avoid the vulnerabilities in the announcement above we do recommend uninstalling the QuickTime software.
Q: If I uninstall QuickTime can I still import .MOV files in Camtasia Studio 8?
A: If the .MOV file is encoded in H.264 video and AAC audio that file can be imported and played without the use of QuickTime. If it doesn't import, simply change the extension of the file to .mp4 instead of .mov and try importing again. Any other type of .MOV files will not be able to be imported into Camtasia Studio.
Q: What can I do if I need to edit a .MOV that is not able to be imported into Camtasia Studio 8?
A: We recommend converting that .MOV file to a .MP4 using a free tool called Handbrake. We have a video on how to use Handbrake here.
Q: Can I still export to a .MOV file?
A: No. Starting in Camtasia 9 we no longer offer the ability to export to MOV. However, any player that could play an MOV file can also play an MP4 file.
