Export of my video is blown out. Footage is fine in the premiere sequence. Recorded on iphone.

I've tried everything online nothing is working. I need help.

Your iPhone is set to record HLG files, a form of HDR. You need to go into the Project panel, select one or more clips, right-click/Modify/Interpret Footage.

At the bottom of that dialog are the new color management controls.

Use the Override option, and set the option to Rec.709.

You may need to redo your color correction for those files now, but the exports will work.
