I said something… I forget what…
I tried to post that a minute after my last post but got a msg from your forum software that since I was a noob I had reached my max and had to wait 20 hrs.
So I went off and tried virtualbox and wondershare and that works so that is my solution. So simple.
release was 25.04.2 flatpak. Whatever Mint Cinn Software Mgr gave me.
Tried at about midnight my time:
“An error occurred: We appreciate your enthusiasm, keep it up! That said, for the safety of our community, you’ve reached the maximum number of replies a new user can create on their first day. Please wait 13 hours and you’ll be able to create more replies.”
so that’s about 1pm my time.
“An error occurred: We appreciate your enthusiasm, keep it up! That said, for the safety of our community, you’ve reached the maximum number of replies a new user can create on their first day. Please wait 1 hour and you’ll be able to create more replies.”
1:30?
This will be my last post - don’t want to overload your system. I’d probably be quickly limited to another 20 hr wait anyway! 
you said: “kdenlive is just rendering exactly the ‘garbage’ you have fed it and the issue is in your source clip” DJI camera. Many flawless vlogs via win. Same clips rendered flawlessly w WF on virtualbox on Mint Cinn 22.1 current. But must be the clips!
You folks and this forum are, uh, “interesting”.
