1080 i60肯定不是升格啊，这不影响你放映的帧速率

创天君給力阿!我看過最認真的售服技術支持!:)

不客气。。AND，我是创天君，不是天创君哇~~

:handshake谢谢解惑。。。

升格拍摄与降格拍摄，是电影摄影中的一种技术手段。电影摄影拍摄标准是每秒24格，也就是每秒拍摄24张，这样在放映是才能是正常速度的连续性画面，但为了实现一些简单的技巧，比如慢镜头效果，就要改变正常的拍摄速度，比如高于24格/秒，这就是升格。打个比方，就是一秒钟拍了30格，但是一秒钟只播放24格，放映效果就是慢动作。如果降低拍摄速度（低于24格/秒），就是降格。比如一秒钟只拍了15格，但是一秒钟播放了24格，放映效果就是快动作。 以上是我百度的内容。 那根据这个解释的话，1080i60就不是升格拍摄了。 电影放映的时候，是一秒24帧。而视频图像PAL制式每秒50帧，NTSC制是每秒60帧，但是1080i60是隔行扫描，所以可以大概认为PAL制每秒25个完整视频帧，NSTC制30个完整视频帧（1080P30就可以直接认为是30帧完整视频）。 当需要把电影转换到电视上进行播放时， 电影和PAL每秒只差1帧，所以以前一般来说就直接一帧对一帧进行制作，这样PAL每秒会比电影多放一帧，也就是速度提高了1/24，而且声音的音调会升高。 而NTSC因为每秒有30帧，不能直接一帧对一帧制作，所以要通过PULLDOWN（简单的描述就是，把24帧拆成30帧进行播放，所以电视上每一帧包含的信息量实际上并不是完整的一帧电影的信息量）的办法把24个电影帧转成30个视频帧，这30个视频帧里所包含的内容和24个电影帧是相等的，所以NTSC的播放速度和电影一样。 写了这么多，希望我能描述得明白。 那么，简单的结论就是，1080i60不是升格拍摄的意思。 楼楼，你要不要给我点个赞。。:dizzy:

是的， 百度了好几天，也没个固定的说法，还是我脑子太笨了:Q

天创君你，我不明白的其实就是1080 60I是不是升格拍摄的意思

速度应该没加快吧，不是还是相当于30P的FPS吗？然后，其中一个好像更smooth一些，一个更sharp一些。30p （progressive）的好像更清楚更“亮”一些，但是60i （interlaced）的好像拍运动的物体更“顺”一些。但是这个真心不怎么懂，网上的资料也是有点儿乱。 可以看看这个人写的： Its resolution v smooth movement (temporal information). 60i is 60 samples taken per second, but each sample is only half the resolution of the full screen. This gives you "video" motion which is smooth, even with fast camera pans or fast moving action. Because each sample is only half the resolution, when something moves it is only captured with half the detail. You can see this sometimes at the start of a slow camera pan resolution can drop, when you stop panning and hold the camera steady the picture resolution improves. This wasn't so noticeable with 60i at SD resolutions but more noticeable with HD. Also 60i is optimised for interlaced displays, but we don't use them anymore, we have progressive displays. This means the TV has to convert the 60i to 60p using various tricks, which can degrade the picture quality or introduce artefacts. 30p is 30 samples taken per second at full resolution. Because of the lower sample rate, movement and camera pans may not look so smooth, so you need to be careful with 30p not to have two much fast motion or fast camera pans, so not the best format for sports for example. 30p displays better on modern TVs as it is progressive to progressive. When something moves the resolution doesn't drop, but ironically our eyes, especially with LCD TVs, trying to track the motion with a low sample rate of 30 frames a second, causes us to perceive a blurring anyway. (We are moving our eyes over a series of static pictures, so it's like camera blur). 30p is great for the Internet and YouTube however as it is a good compromise, and internationally the majority of monitors refresh at 60p, so to display 30p on 60p monitors each frame is shown twice. The best option is 60p if you have it, this is the best of both worlds, although not good for the internet due to the bandwidth requirements and can be difficult to edit and maintain 60p playback on your TV.
