HEICĪn HEIC file is one specific way to use HEIF, in which the HEIF container relies only on HEVC to encode images. It’s a more robust, more compatible way to ensure files can be read across systems, even far into the future. Because HEIF is a container, each discrete image or sequence has its own file within the container, and metadata is stored in separate files as well. But each of these options requires, in effect, unpacking the entire file. A long-ago change to GIF allowed the integral storage of multiple frames for animations, and TIFF can support multiple pages in a single file. Older image formats like GIF, JPEG, PNG, and TIFF pack metadata into the image file, usually at the start. You can think of a container format as a sort of folder within a file. It also allows for multiple images stored as a sequence (such as a burst mode) or to enable simple animation (as with Live Photos). It supports an image stored by itself, potentially with added modification layers from an image-editing program, alpha masking, and depth layers. HEIF is a container format developed by the Moving Picture Experts Group, which has created many licensed audio and video formats. HEVC can compress still images or sequences of video. H.265, which is just another name for HEVC, provides substantial improvements in compression by being more clever and versatile in analyzing individual frames of video and then equally smart in storing differences between adjacent frames. Since we couldn’t easily sort it out despite the fact that we live and breathe this kind of thing, we spent some time teasing it all apart for you. But the company doesn’t mention HEIC or the use of MOV for storing HEVC-even on the page on which it explains HEIF and HEVC. MOV is a video container format that can hold media encoded in many different ways, including HEVC.Īpple discusses HEIF and HEVC in various places, including in Settings > Camera > Formats, where you choose between High Efficiency for the newer formats and Most Compatible for JPEG and H.264-though H.264 is also stored in a MOV container. The latter is potentially even more confusing since MOV files have been around for decades. The former, HEIC, apparently stands for High Efficiency Image Container-more on that in a moment. See “Take a HEIC: Make Sure AP and Other Test Uploads Work from Your iPhone and iPad,”. (This came up because of the College Board mishandling iPhone images. While Apple uses those terms, files created using those schemes are stored, respectively, with the filename extensions. (For the technical nitty-gritty, read “ HEVC and HEIF Will Make Video and Photos More Efficient,” 30 June 2017.)ĭespite all of this happening nearly three years ago, we at TidBITS found ourselves scratching our heads recently about HEIF and HEVC. HEVC (High Efficiency Video Coding), also known as H.265, can encode video using 40–50% less data than H.264 while maintaining the same quality.HEIF (High Efficiency Image File Format) is a container format that allows extensive metadata, still images, and sequences (like bursts or Live Photos) to co-exist in a single file.In 2017, Apple added support for successors to JPEG for images and H.264 for video: But that gets you only part of the way there. It expanded maximum storage so that a 256 GB iPhone isn’t ludicrously expensive. To store more photos and videos on a mobile device, you can either buy more storage or increase image compression. What the HEIC? Apple’s Highly Compressed Image Format Still Confuses
