Should I film in 6K?
Short Answer:
Film in 6K when you need maximum reframing flexibility, plan to deliver in 4K, or want the highest-quality result for premium work — such as commercials or hero brand films. For most standard business video, 4K is more than enough, and 6K's much larger files and heavier processing demands are not justified. Match the resolution to the project, not the spec sheet.
Overview
6K offers even more detail and cropping room than 4K, but at a significant cost in storage and processing. It earns its place on high-end work where reframing latitude and ultimate quality matter, and is overkill for routine content.
Detailed Explanation
When 6K makes sense
Heavy reframing: extract multiple usable framings from one shot, or crop into detail.
4K delivery: downsampling 6K to 4K yields an extremely clean result.
Premium projects: commercials and flagship films where quality is paramount.
VFX and stabilisation: extra resolution helps effects and post-stabilisation.
The downsides are substantial: 6K files are far larger, demand fast storage, and need powerful editing hardware. For everyday corporate and social content, 4K delivers professional results without the overhead.
Example
A high-end commercial might be shot in 6K so the editor can reframe hero shots and deliver a pristine 4K master, whereas a routine talking-head video gains little from 6K over 4K beyond bigger files.
