'Base Station of Amateur Rocket

So i have been doing some amateur rocket launches and came up with the idea of telemetry. I am using an raspberry pi zero w 2 and an IMU 6050 to collect data from the flight. I will also use the camera module of the Pi since i will try to transmit video footage. Be aware the rocket is not expected to reach more than 500 meters.

So there are a few questions that have struck my mind:

1) What protocol should i use in order to achieve a solid video transmission?
2) Regarding the base station, should i use a laptop or a configured raspberry pi, what would 
   be simpler?
