The main idea here is how higher resolution changes every part of the production pipeline: image detail, the amount of data you handle, and what that means for editing, processing, and deliverables. 1080p (1920x1080) provides a solid baseline of detail, with modest file sizes and reasonable processing demands. 4K increases the pixel count significantly (depending on the exact variant, UHD around 3840x2160 or DCI 4096x2160), which yields noticeably more detail and implies more data per second. That extra data drives higher storage and bandwidth needs, longer render and pre/post processes, and greater GPU/CPU load during editing, color grading, effects, and transcoding. Because of that, workflows often shift to proxy media for editing and then render full-resolution masters for delivery, and deliverables may include both 4K masters and downscaled versions for different platforms. In short, 4K brings more detail and more data, and it forces bigger, more resource-intensive post workflows and deliverables. The other options either misstate the actual resolutions or imply the workflow remains unchanged, which isn’t accurate given the increased data and processing demands.
