Low framerate Export

When I export a video at 30 fps it comes out with a noticeably lower FPS I can see while playing both videos side by side.
I checked the video in the editor and the exported video and both say 30fps not 1000fps as I see a lot of people having issues with.
It’s all 1 video I’m editing so it’s not separate videos with different frame rates causing the export to break so I’m lost as what’s wrong and can’t find the answer anywhere if it exists.

What’s your input / output?
What do you wan’t to do ? Slowmo ?
1000fps really ? Or equivalent to 1000fps?
