How long is your stride?
Most pitchers have a stride that is 90%-110% of their height.
And like TropicalJoel said, you are very upright. You don't seem to get any hip/shoulder separation (delayed shoulder rotation leads to H/S separation)
I do not see an equal and opposite position.
It LOOKS like your glove is in front of your chest when your throwing arm is extended back when you have strided out. They should semi mirror each other in a balanced way (stick that glove out and keep it over your foot.)
This isn't 100% expert testimony and the camera quality and fps isn't very good. Just what I think.
