Less than a minute but a lot of information in this video.
First off, again, the push press being similar to the dip and drive of the high hang snatch / clean.
Second, that oftentimes a lot of athletes, in their attempt and desire to generate momentum and power for their lifts, will cock their hips back and hip check the bar forward like they would for a kettlebell swing.
While this does generate momentum, it unfortunately sends the bar forward, away from the lifter, instead of up - so now the athlete has to chase the bar forward and doesn't have as much room to get under the bar.
Stand up straight, have good positioning, dip and drive / jump up and back, then get under the bar.
