![]() Over the years, HEIF has been enriched by new features. Thanks to HEIF being a standard format, the Alliance for Open Media has specified the storage of their AV1 video format in HEIF. Now, the latest international video standards, including the Versatile Video Coding (VVC) standard, have also been added in HEIF. ![]() The initial version of HEIF supported HEVC. Nokia has published a suite of examples, demonstrating the versatility of HEIF for a variety of use cases. HEIF also included basic non-destructive image manipulation operations without the need to re-compress the image, such as 90°, 180°, and 270° rotation, cropping, overlaying images, and forming an image grid. The resulting standard was perfect for multi-image use cases such as animations, burst captures, and the storage of auxiliary images, such as alpha planes and depth maps. Nokia, together with other key contributors, completed the first version of HEIF in 2015. While HEIF is a structural format that can include images compressed with any codec, a key driver in the initial version of HEIF was the HEVC standard, largely thanks to its superior compression at that time and rich 10-bit color component fidelity range. Adding the storage of still images on top of this solid foundation was one the first steps in the development of HEIF. It was built on the foundations laid by the broadly supported ISO Base Media File Format (ISOBMFF), which provided support for real-time media streams, such as audio and video. The first working draft of HEIF was authored in 2013. With the insights we gained, it was natural for us to start driving the development of an image format in the Moving Picture Experts Group (MPEG), with the goal of creating a flexible file format for image applications. Nokia was one of the very first companies to develop photography use cases that went far beyond capturing still images. From first sketches to standard completion In honor of its tenth anniversary, let’s have a look at the evolution of this storage space saving standard that has been implemented into billions of smartphones and digital cameras all over the world ever since its first draft release. And so, the High Efficiency Image File Format (HEIF) came to be. Over a decade ago, Nokia’s engineers realized that a technology called the High Efficiency Video Coding (HEVC) standard, which was still under development in 2012, would provide excellent compression of still images and could potentially become available as a hardware implementation in most consumer electronics devices. ![]() And yet, none of it would be possible without file compression. All of this has revolutionized the way we consume multimedia content. And it’s not just the technology that captures high-quality images and video that makes all the difference – it’s the ability to share them. Camera and photography features in particular have improved in leaps and bounds since the introduction of the first camera phones in the early 2000’s. Not so long ago, mobile devices were very different from what we are used to now. # Download "High five" emoticon: To download this animated smiley, press the right-click on the link highfive.gif and click on the "Save" option.A short history of the high efficiency image file format This emoticon has become available starting from version Skype 5.5 for Windows.
