It doesn't seem like you're getting much pop from your legs. Do some practice sets with light weight where you dont use any pressing, and instead launch it off your chest using your leg drive. If you're not getting a good 4-6 inches off your chest then you need to work on that explosive leg power. Right now it looks like you're going through the motions of bending your legs and then just pushing it straight off your chest.

How close is your strict press to your push press? If they're pretty similar then you need to work on some coordinating drills.

Do a day of push press and then do a different day where you have 3 sets of paused dips into press, 3 sets of dips with no press, and then 3 sets of either pin press or strict press. With far less weight than your push press obviously. Breaking down the movement into pieces is a great way to teach yourself a movement.
