High 10 Profile (Hi10P), also just known as 10-bit. The newest standard for fansubbed and encoded releases.
What is Hi10P?
In really basic terms, more data is used to define color which means there is less banding for a smaller file size. It's an H.264 profile which uses 10 bits of information to represent color. It's a huge improvement because there is less file size, which in the long run saves bandwidth.
- Significantly higher compression ratios resulting in vastly decreased file sizes. In return, a huge amount of bandwidth is saved.
- Far more information is preserved from the original, removing such issues as banding and poor detail in dark scenes.
- Less things for the encoder to worry about.
- Slower decoding and encoding.
- No support for DXVA or CUDA as of writing.
- Slight compatibility issues with older devices during playback.
