When I tried to ADD MEDIA using the ELEMENTS ORGANIZER all the thumbnails were black. When I chose one I could open it but in the dialog that comes up to let you choose the IN and OUT points all frames of the video were still black. If I open the ORGANIZER directly all the GoPro MP4 clip thumbnails were also black but the videos would play in ORGANIZER. I searched these forums and found a suggestion to change the file extensions from MP4 to MOV. I did that. First I did it for one clip only and went through the processor trying to ADD MEDIA in PE. I had a thumbnail and I could see the video to set the IN and OUT points. I then converted all the files using a command line (ren *.MP4 *.MOV). Afterwards the clips will not open in ORGANIZER at all and there are no thumbnails, only icons (I added the "new" files first. In PREMIERE ELEMENTS when I ADD MEDIA using the organizer there are messages instead of thumbnails with an orange triangle. When I try to open one I get an error that says "This type of file is not supported or codec is not installed." Note that I can open and play the renamed files in VLC player. If I try to open the files via ADD MEDIA and just opening a folder, I actually see the thumbnails but cannot open the file.
I do not want to reduce all these clips using GoPro Studio. I have almost 20 hours of video in 400 files to reduce down to 3 minutes.
Configuration: New Windows 10 PC 64-bit, latest i7 processor, 32Gb RAM, very little software installed so far. Premiere Elements and Photoshop Elements and Organizer.
Have you got Quicktime 7 installed, per the program's system requirements?
Now that would be an unfortunate requirement considering that Apple stopped supporting QT for Windows and that there have been at least two identified and now un-patched security vulnerabilities in QT for Windows. No I do not have QT7 and am afraid to install it.
You do need to install it in order for the program to edit a number of video formats including, of course, Quicktime.
At Muvipix.com, we can show you how to install the necessary components without installing Quicktime Player. You can also install the whole packet and then change the .exe suffix on Quicktime Player to make it non-functional. Or you can just leave it and never use Quicktime Player.
But you do need Quicktime.
