Which statement best describes common export formats and settings for web delivery versus broadcast?

• A. Web delivery typically uses ProRes, DNxHR, or higher-bitrate codecs.
• B. Web: H.264/MP4 at 1080p or 4K; Broadcast may use ProRes, DNxHR, or higher-bitrate codecs; consider resolution, bitrate, color space, and delivery specs.
• C. Broadcast uses only MPEG-2.
• D. Web delivery uses 4K uncompressed video.

Answer: (B)

The key idea is that export formats and settings are chosen to fit how the video will be delivered and viewed. For web delivery, the goal is broad compatibility and efficient streaming, so widely supported codecs like H.264 in an MP4 container are used, typically at 1080p or 4K. This balances good visual quality with smaller file sizes and fast decoding across browsers and devices. Newer codecs like H.265 can also be used, but H.264 remains the most universally supported choice for online platforms. For broadcast, the priority is higher fidelity and compatibility with professional pipelines, so higher-quality codecs such as ProRes or DNxHR are common. These codecs preserve more detail and color information, which is important in post-production and broadcast workflows, and they often support higher bit depths and specific color spaces that networks require. Broadcast deliverables also come with strict specifications for resolution, bitrate, color space, and other metadata, which is why the statement mentions considering those aspects. The correct statement captures this distinction: web uses efficient, browser-friendly codecs like H.264/MP4 at 1080p or 4K, while broadcast may use higher-bitrate, professional-codecs like ProRes or DNxHR, with careful attention to resolution, bitrate, color space, and delivery specs. The other options describe scenarios that don’t align with typical web or broadcast practices.
