Different image contrast issue between preview window, original and final upload
So I'm having this issue with differing contrast with the video I'm trying to edit and upload to YouTube.
In the picture attached the original video is on the right and the premiere pro preview window is on the left, any way to get the preview window to look like the original so I can colour grade accurately?
Actually that's not even the biggest issue, once exported the image looks again the same as the original if played in windows media player (for which I have installed the h.265 codec). If played in VLC for example, it looks like the preview window (and looks like a lower quality image than wmp in my opinion).
Ultimately I want the end product to look the same on youtube as my original final exported video (minus compression but that's not the problem).
The image on the right looks way better than the one on the left it has more dynamic range, details are softer in the dark areas etc. If I try to increase exposure in preview to get the same look the colours and details look all blown out and just pretty bad so it's not something simple like that.
Video was shot in h.265 DJI Air 2s normal colour profile 4k.
I have also tried exporting in h.264 but that doesn't change anything.
Any help will be HUGELY appreciated! Thanks!
