[請問] 關於影音檔的品質
請問到底要怎麼評斷影音檔的品質呢?
最庸俗的方法可能是檔案越大越好
接下來可能是看解析度 例如 460p 720p 1080p之類的
甚至看 bit rate 或是 fps
請問有沒有一種比較精確嚴謹 的一套判斷方法
常常看到有人分享所謂高清1080P的檔 可是bit rate卻可以從5M~35M不等
為什麼又有這些差別呢?
目前不是1080P就是最頂級嗎?
總而言之 判斷一個影像檔的好壞 要參考哪些資料? 而順序又是如何?
壓縮方式? 包裝方式? 編碼方式?
那BD又是如何的呢? 有比BD更好的嗎?
板上或精華區有沒有推薦哪幾篇文章可以指點這類知識?
或是有前輩可以指點?
感謝
