介紹一下相關格式(節錄自維基百科)High Profile (HiP)
The primary profile for broadcast and disc storage applications, particularly for high-definition television applications (for example, this is the profile adopted by the Blu-ray Disc storage format and the DVB HDTV broadcast service).
High 10 Profile (Hi10P)
Going beyond typical mainstream consumer product capabilities, this profile builds on top of the High Profile, adding support for up to 10 bits per sample of decoded picture precision.
High 4:2:2 Profile (Hi422P)
Primarily targeting professional applications that use interlaced video, this profile builds on top of the High 10 Profile, adding support for the 4:2:2 chroma subsampling format while using up to 10 bits per sample of decoded picture precision.
High 4:4:4 Predictive Profile (Hi444PP)
This profile builds on top of the High 4:2:2 Profile, supporting up to 4:4:4 chroma sampling, up to 14 bits per sample, and additionally supporting efficient lossless region coding and the coding of each picture as three separate color planes.
一般影片的Chroma subsampling是4:2:0
此影片則為4:4:4
有興趣想測試再下載吧~

面對少見的10-bit 4:4:4格式,LAV Video Decoder照樣能勝任...
