情報來源：https://reurl.cc/b7DMnl 軟體版本：Infuse 7.5 Even more Dolby Vision Dolby Vision comes in many different flavors, and today we’re adding expanded support for Dolby Vision Profile 8. Profile 8 is a unique format, as it includes both a Dolby Vision layer and an HDR layer. It has been used by Apple for many of their screensaver videos, and now more of these videos can be played natively in Infuse in full Dolby Vision. By default, the best video playback option will automatically be selected based on the video file and the device you are using, and you can change how this works by adjusting the Extended Dolby Vision option found in Infuse > Settings > Playback. Note: Since Profile 8 has a number of different sub-variants with a wide variety of characteristics, a portion of Profile 8 videos will gracefully fall back to playing in HDR10 — which will still look great. --------------------------------------------------------------------------- 今天更新Infuse 7.5，可以支援Dolby Vision(profile 8)囉 ~ 常用的Dolby Vision大致有下列兩種，順便介紹給大家認識。 Dolby Vision (profile 5) 編碼：10-bit HEVC BL/EL層：無使用色彩空間：IPTPQc2，也稱IPTPQc2/IPT。常用地方：主流的串流，像是Netflix、Disney+等這類的DV影片，大多屬此類。 Dolby Vision (profile 7) 編碼：10-bit HEVC BL/EL層：有，BL:EL 4:1。(UHD) 常用地方：UHDBD，4K藍光原盤。判別方式：再進行remux時，會看到視訊軌道會有二條，第一條4K屬BL層，第二條1080p屬EL層。主要利用此兩條軌道合成Dolby Vision的影像。新增支援的是Dolby Vision (profile 8) 編碼：10-bit HEVC BL/EL層：無 profile 8 目前好像沒啥主流應用，似乎只是讓他可以向下相容其他HDR規格而已!? 如：8.1可以相容HDR、8.2可以相容SDR、8.4可以相容HLG。以上資訊提供給大家，如有錯誤，煩請指證。備註：Infuse目前可支援Dolby Vision (profile 5及profile 8)，但無法支援Dolby Vision (profile 7)。 -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 163.21.190.42 (臺灣) ※ 文章網址: https://www.ptt.cc/bbs/Digitalhome/M.1678927142.A.87E.html ※ 編輯: apoloo (163.21.190.42 臺灣), 03/16/2023 08:43:55
