What are the practical differences between 1080p and 4K in terms of resolution, data, and post workflow?

• A. 1080p is 1920x1080; 4K is 2560x1440; 4K yields more detail and data; requires more storage and processing; deliverables differ.
• B. 1080p is 1920x1080; 4K is 4096x2160; 4K yields more detail, but post workflow is unchanged.
• C. 4K yields more detail and data and requires more storage and processing, affecting deliverables.
• D. 4K uses the exact same postproduction workflow as 1080p.

Answer: (C)

Understanding this comes down to how many pixels you’re working with. 1080p is 1920x1080, while 4K typically refers to 3840x2160 (UHD) or 4096x2160 for cinema. That means roughly four times as many pixels, so you get more detail when you view at the same size and have more flexibility for cropping or reframing in post.

But more pixels mean more data. Larger file sizes, higher bitrates, and greater demands on storage, bandwidth, and processing power. That translates directly into the postproduction workflow: editing often benefits from proxies to keep playback smooth, you’ll need faster hardware and storage, and color grading, effects, and rendering take longer. Because of these increases, deliverables must be planned with higher-quality encodes, potential downscaling options, and platform-specific requirements in mind.

So the best answer reflects all of that: 4K yields more detail and data and requires more storage and processing, affecting deliverables. The other statements either assign an incorrect 4K resolution or claim the postproduction workflow is unchanged, which doesn’t align with the practical impact of moving to 4K.
