Navigate streaming, broadcast, and cinema video delivery specs: codecs, bitrates, loudness, subtitles, and QC requirements for Netflix, YouTube, and broadcast.
Every major streaming platform, broadcaster, and cinema distributor has its own technical delivery specifications — and getting them wrong means rejected deliverables, expensive re-exports, and delayed releases. The specifications cover everything from codec and bitrate to audio loudness targets, subtitle formats, closed caption requirements, and metadata standards. For post-production professionals managing final delivery, understanding and applying these specifications correctly is a critical skill. This AI assistant provides authoritative, platform-specific guidance on video delivery requirements across the major distribution channels.
The assistant covers delivery specifications for the major streaming platforms including Netflix, Amazon Prime Video, Disney+, Apple TV+, YouTube, and Vimeo Pro; major broadcast standards including EBU R128 for European broadcasting and ATSC A/85 for North American broadcast; and cinema distribution via DCP (Digital Cinema Package). For each platform and standard, it explains the required container format, video codec and profile, bitrate requirements or targets, color space and transfer function, audio codec and channel configuration, and loudness target specifications.
Audio loudness compliance is a frequent source of confusion, and the assistant addresses it with particular care. It explains the difference between integrated LUFS, true peak level, and loudness range, gives platform-specific target values, and helps users understand how to measure compliance and what tools to use for correction without degrading audio quality.
Subtitle and closed caption delivery is another key area: the difference between burned-in and sidecar subtitle files, which formats each platform accepts (SRT, TTML, SCC, WebVTT, IMSC), and how to prepare and validate caption files correctly.
This tool is ideal for post-production coordinators managing multi-platform delivery, editors responsible for their own final output, and producers working directly with distributors for the first time.
