When importing video files, almost all formats/codecs that can be played by your operating system’s video player can also be read by Cinema 4D. These are, for the most part:
当导入视频文件时,几乎所有可以由操作系统的视频播放器播放的格式/解码器都可以被 Cinema 4D 读取。这些大部分是:
出口
The output of rendered animations can be done as individual images or as videos. Note that the most common output is as individual images that are subsequently combined in post-production and finalized in a compressed (= not ideal for further processing but optimized for video devices and software) video format.
渲染动画的输出可以作为单独的图像或视频。注意,最常见的输出是单独的图像,这些图像随后以后期制作的形式合并,最后以压缩(= 不适合进一步处理,但为视频设备和软件优化)视频格式定稿。
Rendered animations can be played in the Picture Viewer and then output as individual images or video.
渲染动画可以在图片查看器中播放,然后作为单个图像或视频输出。
Loaded videos with audio can also be saved with audio.
加载视频与音频也可以保存与音频。
Cinema 4D can save in the following video formats:
Cinema 4D 可以以下列视频格式存储:

麦克
Which format you should use depends on what purpose your output should serve. The most commonly used format is *.mp4.
应该使用哪种格式取决于输出的目的。最常用的格式是 * . mp4。

编解码器设置
These formats use codecs to compress images to create a video. The term compress implies what happens: The image material is combined and is reduced in overall quality (lossy) in the process.
这些格式使用解码器压缩图像来创建视频。压缩这个术语意味着发生了什么: 图像材质被组合在一起,并且在整个过程中降低了整体质量(有损)。
The following settings are available:
以下设置可供选择:
Simply put, a codec is an algorithm that uses keyframes (fully rendered individual images) to calculate the changes from one video image to the next. Depending on the video format used, you can select one of several available codecs or the only codec made available by default. Describing each codec in detail would make no sense here. However, the most current is h.264, which offers the best image quality at a constant data rate.
简单地说,编解码器是一种使用关键帧(完全渲染单个图像)来计算从一个视频图像到下一个视频图像的变化的算法。根据所使用的视频格式,您可以从几种可用的编解码器中选择一种,或者选择默认提供的唯一一种编解码器。详细描述每个编解码器在这里是没有意义的。然而,目前最流行的是 h. 264,它在恒定的数据速率下提供了最好的图像质量。
A separate setting is available for the *.avi format (which is only available for legacy purposes) that uses condecs installed on your computer (but does not support all of them).
* 有一个单独的设置。Avi 格式(仅用于遗留目的) ,使用计算机上安装的 condecs (但不支持所有的 condecs)。
数据速率(kBit)
The data rate in kB/second has the greatest effect on the size and quality of the video to be saved. The higher the value, the larger and of better quality the video will be (and vice-versa). As a reference: for HD videos (1920*1080), the data rate should be a thousand to several thousand kB/second. If the images contain a lot of movment, this rate can also be set higher; for slow camera movement and/or fewer moving objects, lower rates can be set.
以 kb/秒为单位的数据速率对要保存的视频的大小和质量有最大的影响。价值越高,视频就会越大,质量也会越好(反之亦然)。作为参考: 对于高清视频(1920 * 1080) ,数据速率应为每秒1000到几千 kb。如果图像包含大量运动,这个速率也可以设置得更高; 对于慢速摄像机运动和/或更少的运动物体,可以设置更低的速率。
If a value of 0 is defined, an automatic mode will be used (the codec itself will decide which data rate should be used).
如果定义了一个值0,那么将使用一个自动模式(编解码器本身将决定使用哪个数据速率)。
关键帧
This value defines how often a full image should be inserted into a video. A value of 10 means that such an image will be inserted every 10 frames. The smaller the value, the more frequently an image will be inserted, which (most often) results in better quality. Higher values can be defined for calmer sequences and action sequences will benefint from smaller values.
此值定义了将完整图像插入视频的频率。值为10意味着这样的图像将插入每10帧。值越小,插入图像的频率就越高,这(通常)导致更好的质量。较高的值可以定义为较平静的序列和行动序列将有益于从较小的值。
If a value of 0 is defined, an automatic mode will be used (the codec itself will decide how many keyframes will be used).
如果值为0,则使用自动模式(编解码器本身将决定使用多少关键帧)。
音频比特率
This setting can be used to define the audio quality of the video to be saved. The higher the value, the better the quality will be.
此设置可用于定义要保存的视频的音频质量。价值越高,质量就越好。
音频编解码器
Codecs are also available for sound compression (the best known is probably mp3). Depending on the data rate used, noticable loss in quality can be detected. PCs use aac and mp3 and Macs use aac and pcm (the latter loss-free).
解码器也可用于声音压缩(最著名的可能是 mp3)。根据所使用的数据速率,可以检测到明显的质量损失。Pc 使用 aac 和 mp3,mac 使用 aac 和 pcm (后者无损耗)。
音频采样率
This setting defines how often the sound signal should be sampled per second. Normally, a frequency of 44100 Hz is used. The lower the rate, the poorer the quality.
这个设置定义了声音信号每秒采样的频率。通常使用44100赫兹的频率。税率越低,质量就越差。
