PureVideo是要錢的軟體再加上硬體的配合才能發揮

ATI則是在DRIVER裡就可設定
......
第一個部分是視訊攫取(video capture),ATI包含有自動增益控制(Automatic gain control)、3D梳型濾波(3D comb filtering)、12位元類比轉數位轉換(12-bit analog-to-digital conversion)、硬體消除雜訊(hardware de-noising)和數位解調(digital demodulation)等步驟,這些調整都是為了求得高品質的視訊效果。

當訊號都轉成數位時,可以整個直接傳送到解碼階段,如果訊號本身還是類比資料,那就要先送到編碼的單元轉成數位格式,讓圖形處理器可以處理,AVIVO支援H.264、VC-1、WMV9、WMV9 PMC、MPEG-2、MPEG-4和DivX格式,其中H.26是一種同時可以支援Blu-Ray和HD-DVD格式的視訊壓縮標準。
解碼的部分可以將資料轉成H.264、MPEG-2、MPEG...


要錢的軟體又如何...?
畫質沒比較好就要認...

很多地方都可以看出ATI的雜訊還是比較多,畫質也沒比較好
就算有一堆新技術與免費,還是改不了這個事實

而且你怎知他是真的免費?
還是已經加在卡上了?

純白の吸血鬼は微笑む:私を殺した責任、とってもらうからわ - アルクエイド ブリュンスッド
貴方に出逢い STAR輝いて アタシが生まれて
Was aus Liebe gethan wird, geschieht immer Jenseits von Gut und Böse - Friedrick Wilhelm Nietzsche

Cain was the first man ever to strike down another... and when the Lord came to him and said ‘What have you done!?’, Cain could not hide his crime. For the voice of his brother’s blood cried out from the very ground

The world has been your battlefield, everywhere you go. The blood of brothers and sons screams out against you. Perhaps you cannot yet hear it, because the soil is not your own, but you will... you will
