The State of 4K | Filmmaker Magazine

Technology tipping points – when something goes from the unusual to the commonplace – can happen with unexpected rapidity. Has 4K reached a tipping point, and if so what aspect of 4K? Acquisition, production, distribution, or all three? If you’re shooting a film today, should you be shooting in 4K?  The answer to these questions is complicated by cost, complexity and the long-term shelf-life of your project. Today, a convincing argument can be made for shooting in either 4K (future proof) or HD (cost effective and most people won’t see the difference). One thing seems for certain; we will be seeing even more 4K cameras and TVs over the coming months.
