When I add 4K footage from gopro 7 or Canon EOS R Each to Compressor I receive this message: "Error in trying to open source media."

When I add 4K footage from GoPro 7 or Canon EOS R Each to Compressor I receive this message: "Error in trying to open source media."

I have the latest version of Compressor (4.4.1), the latest Pro Video Format app, and have re-installed Compressor, re-started my Mac, and still continue to receive the message. I have a 2017 MacBook Pro, macOS Mojave, the latest version (10.14.1).

All of time before I upgrade, I could add all 4K files but now I can't. How can I fix it? I even copied these files on my macbook but could add them on Compressor. Anyone can help? I read some article on here and someone recommended me format drive, but I can't format all my macbook. Please help

Thank you

Hi Tom. Yes, I transferred all of them to my MacBook. I see not only 4K files, but all files also have end as .MP4 and codecs: Timecode, AAC, HEVC on their info. It's the file on GoPro 7 and Canon EOS R. I can add all of them in Final cut pro X and play with Quicktime, just only a problem is I can't add them on my Compressor. I can use QuickTime to export them to .MOV as HEVC then can add on Compressor. However, that never happens in my Compressor before I upgrade to new macOS Mojave. Do you have any idea?

Thank you

Have you transferred the media off the cards? What exactly are you doing? Can you open the media in the QT player?
