From looking at the specifications of your camera (SJCam 4000), we know already what video compression your camera is using. It is H.264.
A H.264.mov file should be supported by Premiere Elements 11. On what computer operating system is your Premiere Elements 11 running?
Do you have the latest version of QuickTime installed on your computer? And, are you running QuickTime and Premiere Elements 11 from a
User Account with administrative privileges? Please go to Premiere Elements 11 Publish+Share/Computer/QuickTime to confirm that you find
presets there for the QuickTime choice there.
What are the properties of these H.264.mov files - is it 1080p30 (1920 x 1080p30) or something else? Do you know if this camera is recording with a variable or
a constant frame rate?
Please review and consider and then we will decide what next.
Thank you guys for your reply.
The problem was, that I have no instalation of Quick Time on my PC. After installing Quick Time everythink works well.
For your information: operating system is Win 8.1, MOV files are 1920x1080p30
