Should I get a 4K or 1080p action camera?

4K gives you the option to crop in post-production without losing quality and produces sharper footage. But 1080p is lighter on storage and battery. For most people, 4K at 30fps is the sweet spot.

How do I get steady footage without a gimbal?

Modern action cameras have built-in electronic stabilization that rivals gimbals for action scenarios. DJI RockSteady and GoPro HyperSmooth produce remarkably smooth handheld footage.
