Critics and cinematographers have noted that HD technology often creates a "hyper-reality" or "soap opera effect." The high frame rates (HFR) and extreme sharpness of modern HD displays can make film look like video, stripping away the cinematic motion blur traditionally associated with the 24 frames-per-second standard. This has led to a bifurcation in aesthetic preference: while sports and news benefit from the clarity of HD/4K, many filmmakers fight to maintain the "organic" feel of lower frame rates and softer images.
