[Дарина27383970grbl]

Hi! I have this problem with all my videos, nothing can help. If I cut some pixelated episodes from the video it disappeares from this episode, but appears in another ones. And I can't cut everything, it influences on my final video. Please, help me! I'm using iphone pro max 12. Thank you!!!
