Camtasia 18 freezes some times... fades all to gray and says Camtasia not responding.... comes back and all is suddenly ok... and finally rendering is very... very slow. Is it still in beta test? Help..
Hmmm, i don't know what operating system you're on; however, you may want to put a support ticket into TechSmith. Their support service is free and they may be able to help you with your settings on your computer. I haven't had any issues with rendering MP4 files. https://support.techsmith.com
