don't bounce the weight, I'd rather see you do one clean rep with 25 more pounds then that, if you want to do speed deadlifts use lighter weight. You're using the stretch reflex to help you lift the weight but realize that if you are training for singles like in a competition you will not have any except when you first dip.
Correct your form, looks like you'll injure yourself with a slight mistake. tweak that back a little and you wont be able to train for shit.
also your hips are coming up real fast without the bar moving. try doing deadlifts off a platform and don't bounce the weight. you'll see your poundages start to move up nicely cause you'll be able to handle more weight in the initital static pull off the ground.
stay healthy, laters pk
