21.12 Rendering a Video Project
21.12 渲染视频工程

The process for rendering a video project is similar to that for rendering audio projects, but with a small number of options and settings that are specifically video oriented. Most File, Render... dialog options serve the same purpose as for audio projects and do not need any further discussion here. These include render bounds, output files names and directory locations, sample rate, etc. The important differences can be found in the Output format section.
渲染视频工程的过程与渲染音频工程的过程类似,但有少量专门面向视频的选项和设置。大多数文件、渲染...对话框选项的作用与音频工程相同,这里不需要进一步讨论。其中包括渲染界限、输出文件名和目录位置、采样率等。重要的区别可以在输出格式部分找到。
Output format: Video(GIF) is an option if your project contains no audio, but mostly you will want to select Video(libav/FFmpeg encoder). You will then need to select a container format: options are AVI, QT/MOV/MP4, MKV or WEBM. Your choice of video codec and audio codec will depend on which container format you have chosen. This will cause audio content to be rendered in your chosen format. You can select your preferred size and frame rate from the available list (see next page). Frames per second range from 24 to 60 and sizes range from 320 x 240 (QVGA) upwards. There are also options to Keep source aspect ratio and Get width/height/framerate from current video item. Note that the Get width/height/framerate from project option can only be applied if these values have been set in your project settings.
输出格式: 如果您的工程不包含音频,则可以选择“视频(GIF)”,但大多数情况下您会选择“视频(libav/FFmpeg编码器)”。然后您需要选择容器格式: 选项有AVI、QT/MOV/MP4、MKV或WEBM。视频编解码器和音频编解码器的选择将取决于您选择的容器格式。这将导致音频内容以您选择的格式渲染。您可以从可用列表中选择您喜欢的“图像分辨率”和“帧率”(见下文)。每秒帧数从24帧到60帧,分辨率从320 x 240(QVGA)以上。还有“保留源的宽高比”和“从当前视频对象获取宽度/高度/帧率”的选项。请注意,只有在工程设置中设置了“从工程中获取宽度/高度/帧率”时,这个选项才能应用。
If using the Video(ffmpeg/libav encoder) you will need the Video codec VP8 and Audio codec VORBIS. Note that you do also have the option to render in audio only, or video only: in this case, select None as the codec for whichever one you do not want. This applies to AVI, MP4 and WEBM formats.
如果使用“视频(ffmpeg/libav编码器)”,您将需要视频编解码器VP8和音频编解码器Vorbis。请注意,您也可以选择仅音频或仅视频进行渲染: 在这种情况下,选择“无”作为您不想要任何编解码器。这适用于AVI、MP4和WEBM格式。
The remaining options have already been explained. These include the options to Add to render queue for processing later or Render file in real time now.
剩下的选项已经解释过了。这些选项包括添加到渲染队列以便稍后处理,或现在实时渲染文件的选项。
Note: REAPER supports rendering to common video formats on macOS "out of the box" by using AVFoundation. Note that the AVfoundation encoder allows encoding of video only in .m4v or .mov formats.
注意:REAPER支持使用AVFoundation在MacOS上“出厂设置”渲染到常见的视频格式。请注意,AVfoundation编码器仅允许以.m4v或.mov格式对视频进行编码。
For Windows, REAPER includes a limited version of FFMPEG. If you want or need more video rendering formats you will need to install the full FFMPEG libraries. To download the full 64 bit FFMPEG libraries type or copy this into your browser address bar:
对于Windows,REAPER包含FFMPEG的限制版。如果您想要或需要更多视频渲染格式,则需要安装完整的FFMPEG库。要下载完整的64位FFMPEG库,请键入以下内容或将其复制到浏览器地址栏中:
https://www.gyan.dev/ffmpeg/builds/ffmpeg-release-full-shared.7z
This will cause a 7z zip file to be downloaded.
这将导致下载一个7z压缩文件。
If you are using Windows, make sure that the option to view file extensions is enabled in Explorer. Use a program such as 7z, WinZip or WinRar to unzip this file. In the folder of extracted files, look for a subfolder named bin. This contains various files including several with .dll extensions (e.g. filename.dll). You do not need the EXE files, as these are not used by REAPER. However, you will need the DLL files. These DLL files will need to be put into REAPER’s UserPlugins folder.
如果您使用的是Windows,请确保在资源管理器中启用了显示文件扩展名的选项。使用7z、WinZip或WinRar等程序解压此文件。在解压缩文件的文件夹中,查找名为bin的子文件夹。其中包含各种文件,包括几个扩展名为.dll的文件(例如filename.dll)。您不需要EXE文件,因为REAPER不使用这些文件。但是,您需要DLL文件。这些DLL文件需要放入REAPER的UserPlugins文件夹。
To find this folder, from REAPER's main menu choose Options, Show REAPER resource path in explorer/finder. You might have several plug-in folders for REAPER, but the DLL files for FFMPEG must be placed only in the UserPlugins folder. Navigate to this folder and open it. Close REAPER, leaving this folder window open. Copy your DLL files from the extracted FFMPEG archive's bin folder (described above) and paste them into this UserPlugins folder.
要找到此文件夹,请从REAPER的主菜单中选择“选项”--“在资源管理器/访达中显示REAPER资源路径...”。您可能有多个REAPER插件文件夹,但FFMPEG的DLL文件只能放在UserPlugins文件夹中。导航到此文件夹并将其打开。关闭REAPER,使此文件夹窗口保持打开状态。将DLL文件从解压的FFMPEG存档的bin文件夹(如上所述)复制并粘贴到此UserPlugins文件夹中。
Close the UserPlugins folder and restart REAPER. To confirm that you have successfully added the FFMPEG libraries, go to Options, Preferences. Media, Video/REX/Misc. In the top right corner, click on Show available decoder information. In the window that pops up, under ffmpeg/libav it will show Loaded from: as the UserPlugins folder location, along with the name of one of the DLL files you added to that folder.
关闭UserPlugins文件夹并重新启动REAPER。要确认已成功添加FFMPEG库,请转至“选项”--“首选项”--“媒体”--“视频/REX/杂项”。在右上角,单击“显示可用解码器信息”。在弹出的窗口中,在ffmpeg/libav下,它将显示:已加载,从:”,作为UserPlugins文件夹位置,以及您添加到该文件夹的一个DLL文件的名称。
Your Video preferences also include the field Video decoder priority. At the start of the list you should see ffmpeg listed there (and possibly also vlc). The order of these two decoders will determine which decoder is chosen first for playing video in REAPER (but not for encoding a video). You can edit this order if you wish. Sometimes FFMPEG will work better than VLC; you may want to change the order of the video decoders if you are having problems seeing video in REAPER.
您的视频首选项还包括“视频解码器优先级”字段。在列表的开头,您应该看到那里列出了mpeg(可能还列出了vlc)。这两个解码器的顺序将决定首先选择哪个解码器来播放REAPER中的视频(而不是编码视频)。如果您愿意,您可以编辑此顺序。有时,FFMPEG会比VLC工作得更好；如果在REAPER中查看视频时遇到问题,您可能需要更改视频解码器的顺序。

请教一下，在渲染视频时，我选择了视频(ffmpeg/libav编码器)，下面对应的容器里默认是QT/MOV/MP4这个选项，但渲染出的只是MP4，上下光标也没有单独显示MOV格式的，请问这种情况下我要怎么增加MOV格式的选项呢？
