Creating 8K/4K HDR Still-Frame AV1 Videos with Ultra HD Rend Output and HDR Metadata

Creating 8K/4K HDR Still-Frame AV1 Videos with Ultra HDRend Output and HDR Metadata

Are you looking to create 8K or 4K (DCI or UHD) videos with accompanying MP3 audio tracks, where the entire video is a single image? Do you want to include Ultra HDRend output and HDR metadata in your video? If so, you've come to the right place! In this article, we'll cover the key concepts and steps involved in creating still-frame AV1 videos with Ultra HDRend output and HDR metadata.

What is AV1 and why use it?

AV1 is an open-source video codec developed by the Alliance for Open Media. It is designed to provide better compression efficiency than other video codecs, resulting in smaller file sizes and faster transmission speeds. AV1 is also royalty-free, making it an attractive option for content creators and distributors.

What is Ultra HDRend and how does it relate to AV1?

Ultra HDRend is a high dynamic range (HDR) rendering tool that can be used to create HDR video content. It supports a wide range of input formats, including AV1, and can output HDR metadata that can be embedded in the video file. This metadata is used by HDR-compatible playback devices to correctly display the HDR content.

Creating a still-frame AV1 video with Ultra HDRend output and HDR metadata

To create a still-frame AV1 video with Ultra HDRend output and HDR metadata, you'll need to follow these steps:

1. Create a still image that you want to use as the video content. This can be done using any image editing software.
2. Convert the image to the AV1 format using a tool such as FFmpeg. This will result in an AV1 video file with a single frame.
3. Use Ultra HDRend to render the AV1 video with HDR metadata. This will create a new video file with the HDR metadata embedded.
4. Add MP3 audio tracks to the video file using a tool such as FFmpeg. This will result in a final video file that includes the still-frame AV1 video, HDR metadata, and MP3 audio tracks.

Code example: converting an image to AV1 using FFmpeg

Here is an example of how to convert a PNG image to AV1 using FFmpeg:

This command uses the libaom-av1 codec to encode the input.png image as an AV1 video file (output.av1.webm) with a single frame.

Creating 8K or 4K still-frame AV1 videos with Ultra HDRend output and HDR metadata is a relatively simple process that can be accomplished using tools such as FFmpeg and Ultra HDRend. By following the steps outlined in this article, you can create high-quality HDR videos that are compatible with a wide range of playback devices.
