4KKamerabild

4K Kamerabild refers to the image produced by a camera that captures at a 4K resolution. In practice, this term covers both 4K Ultra High Definition (UHD) with a resolution of 3840×2160 and cinema 4K (DCI 4096×2160). The concept is used in German-language media and professional video production to distinguish high-resolution capture from lower formats such as 1080p.

Compared with 1080p, 4K provides substantially more pixels, enabling finer detail, improved digital zoom, and greater flexibility in post-production. The final perceived quality depends on several factors, including sensor size, lens quality, bitrate and compression, and color sampling. Common chroma subsampling options are 4:2:0, 4:2:2, and 4:4:4, with some workflows using higher bit depth and high dynamic range (HDR) for enhanced brightness and color. Native 4K content is often recorded at frame rates ranging from 24 to 60 frames per second, and may be delivered with HDR standards such as HDR10 or Dolby Vision. Codecs frequently used for 4K include H.265/HEVC and the newer AV1, which offer higher efficiency than older codecs.

Applications of 4K Kamerabild span film and television production, documentary work, and streaming, as well as professional video surveillance and broadcasting. In production, 4K footage can be downscaled to lower resolutions or upscaled to 4K for delivery on compatible displays; many cameras also offer 4K capture alongside stabilization and other processing that can affect the final image. The adoption of 4K depends on storage, bandwidth, and display capabilities, but remains a standard expectation for high-detail modern imaging.
