High dynamic range (HDR) videos use a wider range of color and luminance to deliver a high quality image that mimics what a human eye can see. Standard digital videos are referred to as Standard Dynamic Range (SDR).
HDR videos can be uploaded seamlessly to Vimeo in all the same ways supported for any other type of video; however, your video needs to be edited and/or shot in HDR prior to upload on Vimeo.
During the upload process, we will detect that your video is HDR based on metadata in your source file. Once our system reads that your video is HDR, we’ll automatically generate HDR playback files, up to 8K, that use the HEVC (H.265) video codec. The maximum quality depends on your source file’s dimensions.
We’ll also create a set of standard (SDR) versions, as well as wide color gamut (increased color) versions, so you can always view your video in the best quality possible from any playback environment.
Source File Requirements
In order to be considered HDR, your file must be tagged with color transfer characteristics and have a bit depth greater than or equal to 10.
We support both the PQ (SMPTE 2084) or HLG (AKA Hybrid Log Gamma or arib std-b67) transfer functions.
If using the PQ (SMPTE 2084) transfer function, please include the following metadata to ensure the most accurate display of your video’s colors on all devices (in SDR and HDR):
- Mastering Display Color Volume (SMPTE 2086) — This metadata is
usually added automatically in post-production and defines the color
information about the screen where your video was mastered.
- Content Light Level (CEA 861.3) — This metadata is also included automatically in post-production and defines the peak brightness of your video sequence.
