HEVC / H.265 (High Efficiency Video Coding): what it is, how it works and what it does
HEVC (H.265) is a high-efficiency video compression standard that enables high-resolution video recording, such as 4K, on mobile devices.
Definition and Context
HEVC, also known as H.265, is a high-efficiency video compression standard. Its presence in a device indicates the capability to record and play back high-resolution video, such as 4K, while maintaining superior image quality.
Applications in Mobile Devices
In the context of video recording on smartphones, HEVC is used to support high-definition formats. According to the specifications of a mobile device, the HEVC format allows video recording in the following configurations:
- 4K Dolby Vision at 24, 25, 30, or 60 fps.
- 1080p Dolby Vision at 25, 30, or 60 fps.
- 720p Dolby Vision at 30 fps.
Additionally, HEVC support is complemented by other recording features, such as cinematic video stabilization (for 4K, 1080p, and 720p), night mode, and slow-motion video recording (slo-mo) at 120 or 240 fps in 1080p.
Recording Formats
Devices that support HEVC typically offer the option to record in this format or in H.264, the previous standard. Choosing HEVC allows for optimizing storage and image quality at higher resolutions.
Interpreting Its Presence
The mention of HEVC in a product's specifications indicates that the device is designed to handle high-resolution video streams, which is essential for users who need to record in 4K or utilize advanced stabilization and image quality features.
