中文拼音 [zhènglǜyāsuō]
幀率壓縮 英文
frame rate reduction
  • 幀 : 量詞（幅, 用於字畫）

  • 壓 : 壓構詞成分。
  • 縮 : 縮構詞成分。
  1. 2, under equally see the quantity, compress the calculate way s exportation code plain deal connect the good and bad that decide its function of the good and bad, or say, output the code the term of same alike rate the bottom, and the portrait quantity reflected the function of the compression calculate way. adopt with dv all because of the m - jpeg an inside compress the way, efficiency of their compression certainly want lower than mpeg2. certainly, this is an average circumstance, at the time that low code rate, the mpeg2 can compare the m - jpeg compression the ratio high and a lot of but keep the good diagram to resemble the quantity ; but at request the diagram to resemble the quantity the good time for example the sow the room program edit with empress period creation, their difference to is not very big. too is to say, just at the compression efficiency that not emphasize the portrait quantity that the circumstance, mpeg2 is high

    2在同樣的視頻質量下，壓縮演算法的輸出碼率直接決定其性能的優劣，或者說，輸出碼率相同的條件下，圖象質量的優劣反映了壓縮演算法的性能。由於m - jpeg和dv都是採用幀內壓縮方式，它們的壓縮效率當然要比mpeg2低。當然，這是一個平均情況，在低碼率的時候， mpeg2可以比m - jpeg的壓縮比高很多而保持較好的圖像質量而在要求圖像質量很好的時候比如演播室節目編輯和後期製作，它們的差別不是很大。
