Thanks Freddy. It's a codec problem.
I downloaded your file and it opens in my MVPX6 with the green/pink image. That says to me that MVP thinks it can open it but its codecs cannot decode it. Maybe I don't have the necessary codec unlocked or MVP never had the required codec. After all MVP is now an old programme and you have a much newer camera.
IMPORTANT, SERIF SHUT DOWN THEIR UNLOCK SERVER A FEW YEARS AGO SO IF YOU HAVEN'T BACKED UP YOUR UNLOCK CODES YOU URGENTLY NEED TO DO SO. Go to Tools/Options/Advanced and Manage Unlock Codes. Then the Export option. Save the file somewhere safe as you will need it if you reinstall MVP such as on a new PC.
Back to your problem. You have three options:
1 - Download a codec pack such as KLite to see if that helps. https://codecguide.com/download_kl.htm. TP codec packs are not usually recommended but you have not much choice.
2 - Ditch MVP and move onto a newer consumer editor. A new learning curve and you may need a more higher spec pc.
3 - Convert your files into a format MVP can handle. I've converted your file with Handbrake and you can download it here https://drive.google.com/file/d/1-UnkCe … sp=sharing. It works okay in my MVPX6 but may not in yours as it depends on what codecs you have unlocked. Try it in yours.
