Won't import my .mp4 file saying file format not supported.

I've been at this for a while and idk what to do. Idk if i need and update or what but i'm at a loss right now. I was trying to record some gameplay from my dazzle which i recorded with obs while having pinnacle studios in the background for it to capture the audio. It saves as an mp4 but why can't i drop it down or import my file into premiere pro???

Also I'm a windows 8.1 user.

I've heard theres different forms of .mp4's causing issues but i'm still nowhere. I need to see if this even works because i have to see if premiere pro can even deinterlace my video. I'm hoping i can find a solution to this.
