Video not as smooth on youtube

I rendered through Adobe Premiere Pro a video which isn't as smooth when it's been uploaded on youtube as it originally is.

 

My render settings :

Image Frequency : 300

I could not download the file from file.io to compare. ("The transfer you requested has been deleted.")

But it seems that you had a source file that was 300 fps and uploaded a 300 fps file to YouTube. When you uploaded that file  Youtube transcoded the file to 60 fps since that´s a video standard while 300 fps is not. So your 300 fps became 60 fps and thus not as smooth as you want since frame has been dropped.

I downloaded this video as well and it is 60 fps as well though it claims to be 300 fps: This is Warzone in 300 fps (youtube.com)
