如題
最近對4K包含電視還有UHD BD ，之前看蠻多人推薦環太平洋和絕鯊島4K藍光
但是昨天有板友在別篇文章分享國外區別真假4K影片
http://realorfake4k.com/my-product_category/real4k
在這邊的分類似乎是把環太平洋和絕鯊島歸類成假4K是後製的4k影片
並非是從拍攝到後製都有4k 這是真的嗎？
最主要還是注重在廣色域和高亮度的HDR格式
這邊有國外熱心網友整理的一份UHD BD清單，打星號的是畫質有水準之上的
Available NOW:
I've added a red * in front of movies i find to be reference/top 10 quality, in either resolution, HDR, or BOTH. These movies IMO are a great starting point in building a 4k UHD collection!!

其實如果拿最簡單的例子，你可以去比較 美國隊長3 和 X戰警:天啟 這兩部片
前者是DI 4K，後者是DI 2K，但是整體畫質確是後者更優更通透
環太平洋:
攝影機的原始檔(Redcode RAW)是5K
主要後製是2K
絕鯊島:
主要後製是2K
攝影機的原始檔:
ARRIRAW (3.4K) (source format)
ProRes 4:4:4 (2K) (source format) (some scenes)
Redcode RAW (4K) (source format) (high-speed shots)
所以這兩片的UHD應該是重新後製的
神鬼獵人的UHD就是真4K了
這部當初的後製解析度就是4K
攝影機的原始檔甚至有高到6K的解析度
ARRIRAW (3.4K) (6.5K) (source format)
Panavision (Anamorphic)
Redcode RAW (6K) (source format) (some scenes)
