Amazon Prime Video Delivery Specs

Amazon Prime Video: A Different Distribution Model

Amazon Prime Video is fundamentally different from Netflix. While Netflix is a subscription service that controls content exclusively and manages all aspects of presentation, Amazon Prime Video operates a hybrid model: they own original content, but they also host thousands of third-party titles from independent producers, small distributors, and major studios, all competing on the same platform. This means Amazon's delivery requirements are more flexible than Netflix's, but also more complex because they need to accommodate a wider range of content sources and release strategies.

For independent filmmakers, Amazon Prime Video represents a more accessible distribution pathway than Netflix. You can self-publish films through Amazon's direct distribution platform (Amazon Prime Video Direct), or you can work through a distributor or aggregator. Either way, Amazon's technical and metadata standards are critical to understand.

Amazon Prime Video vs Netflix: Key Differences

Submission Process

Netflix: Invitation-only. You cannot submit directly; you must be acquired by Netflix or work through a sales agent/distributor they've approved.

Amazon Prime Video: Open to all. You can submit directly through Amazon Prime Video Direct (if you own the rights), or through approved aggregators and distributors.

Video Format Flexibility

Netflix: ProRes 422 HQ or IMF only. No exceptions.

Amazon Prime Video: Accepts multiple formats: ProRes, H.264, H.265, DNxHR, and others. This flexibility makes it more accessible for smaller producers but means you need to understand which format is best for your situation.

Audio Loudness Standard

Netflix: -24 LKFS ±2 (very strict).

Amazon Prime Video: -24 to -26 LKFS (more flexible range), or can accept files with loudness adjustment metadata.

Metadata Requirements

Netflix: Highly structured, proprietary metadata system. Non-negotiable fields and formatting.

Amazon Prime Video: Uses industry-standard metadata schemas (XML-based). More flexibility in content representation and categorization.

Amazon Prime Video Technical Specifications

Video Codec and Container

Amazon Prime Video accepts multiple video codecs, allowing greater flexibility than Netflix:

• ProRes 422 HQ: Recommended for highest quality. Same as Netflix standard.
• H.264 (AVC): MP4 container, 8-bit, commonly used for streaming masters.
• H.265 (HEVC): MP4 container, 10-bit, more efficient compression for 4K content.
• DNxHR HQX: ProRes alternative, MOV container.

Most independent filmmakers use either ProRes 422 HQ (for maximum compatibility and archival quality) or H.264 (for smaller file sizes and faster upload).

Resolution and Frame Rate

• Resolution: 1920 x 1080 (HD) or 3840 x 2160 (4K UHD). Like Netflix, submit one master resolution, not both.
• Frame Rate: 23.976 fps (cinema), 24 fps, 25 fps, 29.97 fps, or 59.94 fps. Most independent films use 23.976 fps.
• Color Space: Rec. 709 (HD) or Rec. 2020 (4K). Same as Netflix.
• Bit Depth: 8-bit or 10-bit. 10-bit recommended for 4K; 8-bit acceptable for HD.

Aspect Ratio and Safe Area

Amazon allows multiple aspect ratios (16:9, 2.35:1, 4:3, etc.) but requires letterboxing to your specified delivery resolution. Essential action and text must remain within the 1.85:1 safe area.

Audio Specifications

Audio Tracks

• Required: Stereo (2.0) or 5.1 surround required. Dolby Atmos is supported but must accompany a 5.1 mix.
• Codec: AAC, AC-3 (Dolby Digital), or E-AC-3 (Dolby Digital Plus).
• Sample Rate: 48 kHz.
• Bit Rate: 192 kbps (stereo), 384 kbps (5.1), or 640+ kbps (Dolby Atmos).

Loudness Specification

Amazon accepts a more flexible loudness range than Netflix: -24 to -26 LKFS, measured using ITU-R BS.1770 standard. You can also submit files with loudness metadata (ADM), allowing Amazon's platform to adjust loudness automatically without requiring you to re-mix.

Subtitles and Captions

Amazon requires subtitles in the original language (if offering an international release) and English (if original language is not English). Closed captions are required for English-language audio. Subtitle files must be in SRT, WebVTT, or TTML format, UTF-8 encoded. Unlike Netflix, Amazon allows more flexibility in subtitle timing and formatting.

Metadata Requirements

Essential Metadata Fields

When submitting through Amazon Prime Video Direct or an aggregator, you'll need to provide:

• Title and Alternate Titles (original language, English translation if applicable)
• Synopsis (short 150-character and long 500+ character versions)
• Genre (Amazon uses specific genre tags; multiple genres allowed)
• Runtime (in minutes)
• Release Date (original release, theatrical release, or Amazon exclusive release date)
• Content Rating (G, PG, PG-13, R, NC-17 in US; equivalent in other territories)
• Cast and Crew (director, writers, producers, main cast—up to 10 cast members typically)
• Artwork (poster image, typically 1000 x 1500 pixels in JPEG format)
• IMDb ID or other identifiers (helps Amazon link to external databases)

Language and Localization

Amazon supports content in multiple languages and currencies. If releasing internationally, provide title, synopsis, and metadata in multiple languages. Amazon's system will automatically show the appropriate language version to viewers in different territories.

File Naming and Delivery

File Naming Convention

Amazon has less strict file naming requirements than Netflix, but you should still follow a clear naming convention:

[FilmTitle]_[Resolution]_[Codec]_[AudioSpec].[ext]

Example: MyFilm_1080p_H264_Stereo.mp4 or MyFilm_4K_ProRes422HQ_51.mov

File Submission Method

Amazon Prime Video Direct uses a web-based upload system. For larger files (over 5GB), you can request an FTP upload link or use Amazon's S3 storage service. Most independent filmmakers use the web interface for initial uploads, then transfer to FTP or S3 if needed for revisions.

Quality Assurance and Playback Testing

Amazon's QC Process

Amazon conducts automated and manual QC. Automated systems check for codec compliance, resolution, frame rate, and audio integrity. Manual QC involves watching the film on multiple devices and assessing picture quality, audio sync, and overall presentation.

Pre-Delivery QC Checklist

Before uploading to Amazon, verify:

• Video file plays without errors in industry-standard players (QuickTime, VLC, Adobe Media Encoder)
• Audio loudness is within -24 to -26 LKFS range
• Subtitles display correctly without encoding errors
• Color accuracy matches your graded master (spot-check on multiple monitors)
• No black frames, audio dropouts, or sync issues
• File duration matches expected runtime
• Metadata is complete and accurate in all required fields

Monetization and Release Strategy

Amazon Prime Video supports multiple monetization models:

• Prime Video Direct (TVOD): Transactional Video-on-Demand. Viewers rent or purchase your film. You set the price; Amazon takes 50% commission.
• Prime Video Unlimited (SVOD): Subscription Video-on-Demand. Your film is available to all Amazon Prime subscribers. You're paid per play, typically $0.05–$0.10 per minute watched.
• Advertising-Supported (AVOD): Free with ads. Amazon inserts ads and shares revenue based on viewers and ad impressions.
• Hybrid: Combine multiple models (e.g., TVOD for the first 30 days, then move to SVOD or AVOD).

Choose your monetization strategy based on your audience size and content type. Genre films and niche content often perform better on TVOD (viewers pay to watch). Higher-budget indie films with broader appeal may perform better on SVOD platforms like Prime Unlimited.
