  • Self-Tape Mistakes That Make the Casting Directors Cringe

    Mar 11 2019 · The casting director should be able to see your face eyes and expression in the video. Don t shoot too close or too far. Get it just right and shoot from the waist up. Shooting vertically. Probably one of the biggest self-tape mistakes in casting is viewing a video that was taped vertically.
