Your stirrups are too short. Even though you are jumping, at that height its not really needed to get out of the saddle over jumps, its more freeing their back a little and letting them have their head but its not throwing away the reins!
Its important to ride in a contact, and even if you are trying to get him to stretch out you still maintain a light contact. Its important for a horse when doing circles and jump to have clear commands and a rein to sort of balance on a little.
Imagine trotting along and your rein is bouncing around a little, he's getting commands but you are not giving them. Hold a steady contact but don't pull at his mouth, there should still be a contact over jumps, move with his head rather than giving him rein.
Also over one of the jumps your foot had slipped quite far into the stirrup - remember to keep it on the ball of your foot. Stirrup length may help with this too.
Drop your stirrups. It will improve your seat as well. Also sit back, you are leaning forward. Sorry if I don't sound too positive, there are of course positives but I just don't point them out...hope I helped.
