Shots start left because the face is pointed left of the target line at impact -- ie. is closed to the target line. They go further left because the face is also pointed left of the club path -- i.e. is closed to the path.
Can't see a lot from the full speed video. You seem to have some early extension (hips go towards the golf ball) in the downswing, which can tend to throw the club path excessively out to the right, but if your normal shots are straight-ish draws then you probably don't have a major path issue. Need to focus on why you lose the face to the left on your bad shots.
Some feels that may help to slow down your rate of closure:
-- Left knee stays bent longer into the downswing
-- Right elbow pushes more in front of right hip
-- Right heel stays down on ground longer through impact.
