Hi! There are lots of discussions about digital/optical zooms, but I'd like to put forward one question, and pray that someone may have the prefect answer: Let's say I'm at an athletic games meeting (true story). I'm on the far side of the start of the men's 400 metres. My P4 is in the air stationary a dozen metres away from the starters and I want to stick to a particular runner featuring in the program we were recording. How can I zoom in to find this runner and be sure it's him? I actually got warned off over the speakers because the noise of the drone risked disturbing the start, another reason for needing a zoom function. There are many occasions where the drone is better at distance and the zoom is used either to identify an object/animal, or for recording at the expense of quality and stability, but zoom IS needed before post production. Any iPad software available? Thanks for any help!
