So ive been working on an edit and i noticed i had this spot in the top left of my frame (bottom right on other shots, depend on how i hold my camera)(it on my sensor im guessing, sigh, at least its near the edge) and when i export it full quality... it disappears... but then reappears when i compress it for online.
look
