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 section on File Formats for suggested bitrates.
Common resolutions for SD video include:
Common resolutions for HD video include:
Note: 4K/UHD video isn't currently supported.
The display aspect ratio defines the proportional relationship between the video's width and height. We support the following display aspect ratios:
Amazon 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.
Important: Always choose "constant" frame rate instead of "variable" frame rate. Variable frame rate sources will be rejected.
