The Main 4:4:4 16 Still Picture profile allows for a single still picture to be encoded with the same constraints as the Main 4:4:4 16 Intra profile. As a subset of the Main 4:4:4 16 Intra profile the Main 4:4:4 16 Still Picture profile allows for a bit depth of 8 bits to 16 bits per sample with support for 4:0:0, 4:2:0, 4:2:2, and 4:4:4 chroma sampling. Scalable Main The Scalable Main profile allows for a base layer that conforms to the Main profile of HEVC. Scalable Main 10 The Scalable Main 10 profile allows for a base layer that conforms to the Main 10 profile of HEVC. Multiview Main The Multiview Main profile allows for a base layer that conforms to the Main profile of HEVC. Version 3 and higher profiles Version 3 of HEVC added one 3D profile: 3D Main. The February 2016 draft of the screen content coding extensions added seven screen content coding extensions profiles, three high throughput extensions profiles, and four scalable extensions profiles: Screen-Extended Main, Screen-Extended Main 10, Screen-Extended Main 4:4:4, Screen-Extended Main 4:4:4 10, Screen-Extended High Throughput 4:4:4, Screen-Extended High Throughput 4:4:4 10, Screen-Extended High Throughput 4:4:4 14, High Throughput 4:4:4, High Throughput 4:4:4 10, High Throughput 4:4:4 14, Scalable Monochrome, Scalable Monochrome 12, Scalable Monochrome 16, and Scalable Main 4:4:4. 3D Main The 3D Main profile allows for a base layer that conforms to the Main profile of HEVC. Screen-Extended Main The Screen-Extended Main profile allows for a bit depth of 8 bits per sample with support for 4:0:0 and 4:2:0 chroma sampling. HEVC decoders that conform to the Screen-Extended Main profile must be capable of decoding bitstreams made with the following profiles: Monochrome, Main, and Screen-Extended Main. Screen-Extended Main 10 The Screen-Extended Main 10 profile allows for a bit depth of 8 bits to 10 bits per sample with support for 4:0:0 and 4:2:0 chroma sampling. HEVC decoders that conform to the Screen-Extended Main 10 profile must be capable of decoding bitstreams made with the following profiles: Monochrome, Main, Main 10, Screen-Extended Main, and Screen-Extended Main 10. Screen-Extended Main 444 The Screen-Extended Main 4:4:4 profile allows for a bit depth of 8 bits per sample with support for 4:0:0, 4:2:0, 4:2:2, and 4:4:4 chroma sampling. HEVC decoders that conform to the Screen-Extended Main 4:4:4 profile must be capable of decoding bitstreams made with the following profiles: Monochrome, Main, Main 4:4:4, Screen-Extended
