Issue with exporting 1080
Hi! I noticed when I upload my reels to instagram and tiktok its quite blurry. Apparently I have to upload in 1080p. For whatever reason its at 2160. And when I try to change it to 1080p it adds big black bars around the video. Im quite new to this, sorry if its a noob question. Can anyone help me get 1080p export by default without getting this issue? Attached images so you can see what I mean.
