想问大家一个低级问题
想问大家一个低级问题，1920 x 1080p23.98,
1920 x 1080p24,
1920 x 1080p25,
1920 x 1080p29.97,
1920 x 1080p30
上面这些帧数不同会有什么区别？
比如效果上是不是有区别？哪个帧数的效果会更好？还是拍特定的东西需要调成不同的帧数？
因为不是这个专业出身，之前都用5d拍摄，一直都用30p拍摄，希望大家帮忙解答一下，感激不尽^09^ 电影标准24P。广播的话有PAL制和NTSC制，分别是23.98和29.97. 根据国家来定 ls说的不对
24p其实就是23.98
ntsc是29.97 就是30
pal是25 duyuwen88 发表于 2014-12-30 21:35

那ntsc跟pal有什么区别？我主要拍些微电影，用什么设置合适一些？比如帧数不同会有效果的区别吗？那摄影机设置里的1920*1080p30跟1920*1080p29.9的区别是什么？ duyuwen88 发表于 2014-12-30 21:35

数字时代有电脑了，无所谓什么模式，只要格式是视频，并安装了相应的解码器，就能在电脑上播放编辑压缩视频，一般来说。 本帖最后由 duyuwen88 于 2014-12-31 09:45 编辑

误导
In the motion picture industry, where traditional film stock is used, the industry standard filming and projection formats are 24 frames per second (fps). Historically, 25 fps was used in some European countries. Shooting at a slower frame rate would create fast motion when projected, while shooting at a frame rate higher than 24 fps would create slow motion when projected. Other examples of historical experiments in frame rates that were not widely accepted were Maxivision 48 and Showscan, developed by 2001: A Space Odyssey special effects creator Douglas Trumbull.
24p is a progressive format and is now widely adopted by those planning on transferring a video signal to film. Film and video makers use 24p even if they are not going to transfer their productions to film, simply because of the on-screen "look" of the (low) frame rate, which matches native film. When transferred to NTSC television, the rate is effectively slowed to 23.976 FPS (24×1000÷1001 to be exact), and when transferred to PAL or SECAM it is sped up to 25 FPS. 35 mm movie cameras use a standard exposure rate of 24 FPS, though many cameras offer rates of 23.976 FPS for NTSC television and 25 FPS for PAL/SECAM. The 24 FPS rate became the de facto standard for sound motion pictures in the mid-1920s. Practically all hand-drawn animation is designed to be played at 24 FPS. Actually hand-drawing 24 unique frames per second ("1's") is costly. Even in big budget films, usually hand-draw animation is done shooting on "2's" (one hand-drawn frame is shown twice, so only 12 unique frames per second) and some animation is even drawn on "4's" (one hand-drawn frame is shown four times, so only six unique frames per second).
25p is a progressive format and runs 25 progressive frames per second. This frame rate derives from the PAL television standard of 50i (or 50 interlaced fields per second). Film and television companies use this rate in 50 Hz regions for direct compatibility with television field and frame rates. Conversion for 60 Hz countries is enabled by slowing down the media to 24p then converting to 60 Hz systems using pulldown. While 25p captures half the temporal resolution or motion that normal 50i PAL registers, it yields a higher vertical spatial resolution per frame. Like 24p, 25p is often used to achieve "cine"-look, albeit with virtually the same motion artifacts. It is also better suited to progressive-scan output (e.g., on LCD displays, computer monitors and projectors) because the interlacing is absent.
PAL 25 我搞错了但是23.98不是24， 29.98不是30

那帧速率对视频的画质和观感有影响吗？比如30p是不是比25p的视频效果更好？ duyuwen88 发表于 2014-12-31 09:43

看你的播放平台吧
电影的格式都是24p
国内的电视制式是pal 25p（50i）
微电影一般会拍24p的
当然根据你的创造 帧率可以改变的
比如武打镜头 会用22p 降格拍出来显得动作较快
升格可以排出慢动作等等 橙果媒体-罗某人 发表于 2014-12-31 14:56

同样的码率 30肯定画质稍差 但是差距太小了 看不出来 Infantry 发表于 2015-1-1 01:48

亲 你想拍微电影 是不需要知道这些的 这些是理论基础跟你拍不拍的好微电影没有关系 摄影机拍摄是24格/秒，就是24p。
根据特殊需求，高于24格/秒，就是升格，拍摄出来就是我们常见的“慢动作”。
低于24格/秒，就是降格，拍摄出来就是“快动作”。
