Cinema delivery standards for projection typically require which encoding and frame rate?

• A. JPEG 2000 encoding, 24fps, 2K/4K, 5.1/7.1 audio
• B. H.264, 30fps
• C. MP4, 60fps
• D. ProRes 422

Answer: (A)

Cinema delivery standards for projection follow what DCI (Digital Cinema Initiatives) specifies. The image data are encoded with JPEG 2000, the frame rate is a steady 24 frames per second, the resolution is 2K or 4K, and the audio is multi-channel, typically 5.1 or 7.1. JPEG 2000 is chosen because it preserves high image quality and scales well for theatrical playback. The 24 fps rate preserves the traditional film cadence, ensuring smooth motion on cinema projectors. 2K/4K resolutions match the capabilities of modern cinema screens and mastering workflows, while 5.1 or 7.1 audio provides immersive surround sound that cinemas expect.

Other common codecs like H.264, formats like MP4, or editing-focused codecs like ProRes 422 are used in consumer, streaming, or production work, not for final DCP cinema delivery. They don’t align with the standardized DCI packaging used for projection.
