Note: 4K UHD video isn't currently supported on Prime Video Direct.
Our software automatically adjusts the delivery streams to a resolution appropriate to the customer’s device and connection speed. If you submit a 1080p HD video, and a customer streams it in SD, we automatically adjust it for you. For best results, please upload your highest quality video source. After initial publishing, if you submit a revised mezzanine or trailer, it must be at least the same resolution.
There are multiple frame rates that can be used when creating captions files depending on the type of content and standards for your region. Non-Drop Frame timecode means that for every frame of video, there is a corresponding timecode number. The timecode increments without any compensation. In almost all cases, timecode is Non-Drop Frame. The following caption frame rates and Drop/Non-Drop values are supported by Prime Video:
The display aspect ratio defines the proportional relationship between the video's width and height. We support the following display aspect ratios:
Important: Always choose "constant" frame rate instead of "variable" frame rate. Variable frame rate sources will be rejected.
Prime Video Direct supports video sources with the following frame rates: 23.976, 24, 25, 29.97, and 30 frames per second (FPS). There is no requirement to perform frame rate conversion on your content to meet specific regional broadcast standards (e.g. NTSC, PAL, SECAM). For best results, we recommend exporting your videos at the same frame rate at which the content was shot and edited.
If you don’t know what frame rate your content was shot in, select Current or Same as Source when exporting your video.If your footage exceeds 30 FPS, you should encode your video at half that frame rate. For example, if content was shot at 60 FPS, encode your final video at 30 FPS.
Bitrate (also known as data rate) controls the visual quality of the video and its file size. Bitrate for source files is commonly measured in Megabits per second (Mbps). If your video editing software gives you the option, choose a “variable” bitrate. Best practices for video and audio bitrates vary by video format and resolution. Please see the Codecs and file formats section for suggested bitrates.
To minimize delivery of out-of-spec video assets, the following QC software services can be used for testing to perform automated QC on video mezzanines prior to delivery:
The following are common issues:
Prime Video supports trailers for standalone content only. The following requirements apply:
