Video #1 - This would be a good LONG jump! Your wide approach and fairly stright 7-8-9-10 makes you not have to Lean in the turn, which mens you don't get much "throw" into the pit. You travel along the crossbar instead of passing more directly over it on a perpendicular trajectory. You land close to the farther upright which is a key indicator that these things are wrong. You're also head-up and looking at the jump, which prevents a nice arch. Video #2 - Better view to see 8-9-10 in a very straight line, and thus no Lean. Shoulders pointing away from the mat before step 10 even hits the ground - should be facing directly at the farther upright. Sitting position due to chin-on-chest is the big thing reducing your jump heights right now.
