謝謝阿呆徐大大提供的連結! 我在電腦,把YouTube的播放選項,調到最高 4K 2160P,但我還是看不太出來差別。應該在4K大螢幕的電視才分辨得出來吧?! 看底下評論,大部分的人也分辨不出來,有一位Raniie Lee是寫: "100Mbps is a must use setting for low light / night time recording. The rule of thumb is, does your scene need a lot of information to be captured, it's low-light; night time, sport, fast action, etc? If yes, use 100Mbps. If no, you're just recording a fixed scene with hardly any movement on a tripod, then 60Mbps is more than enough." 如果要拍攝低光、夜間、運動、高速動作等等,就使用100Mbps。其它場景,60Mbps綽綽有餘。
