Please help, I'm going insane

Please help me with this problem;

I capture my last 30 seconds on the Xbox/NVIDIA thing
(It doesn't matter if the game (Minecraft) is fullscreen or not)
Then I try to put it in the resolve media pool and it has a green line at the bottom, also I maybe need to point out that it doesn't say to change the frame rate.
* I have a picture where the red box is the game minus the green and the reflection.
(forgot to add that there's a reflection on the right of it)

I tried to give as much info as possible. (If you need anymore be sure to ask, I'll be checking this often)

I've been trying to find this out everywhere for a couple of days and zooming messes up my recording sometimes so I need this! Thank you to anyone who responds and it means the world to me.

I don't know about the cause, but I used HandBrake (free download) to re-encode the captured video to the same format and then the re-encoded file worked in Resolve.

Game recording works much better with a hardware recorder.

So-called "game recorders" create files that are bad for post-production because they use some weird H.264 variant with variable frame rates. Cellphone cameras are often equally bad.

Convert the file to something simple with a constant framerate like DNxHD or ProRes, and you have a chance it will work.

Note that Resolve Studio can play back and process more formats than the free version. Even then, the variable-framerate thing is still an issue.
