You don't need an expensive camera to make great work. Lighting and camera angles/motion has more to do with cinematography than a pretty camera. Become a student to light.

Storytelling is key. Embody the brand insights/values in a story. Understand the brand and its audience to create a resonating story.

Don't boil the ocean. Focus on 1 or 2 selling points. For example, Apple chose noise cancellation for this ad. They didn't touch on ergonomics, bluetooth capabilities, product design, etc.
