Output formats
The file is saved in whichever format has been selected in the pertinent Menu button in the Format Panel (BSG.REN.F.S68.002). From here you can select many image or animation formats (Image and animations formats.). 文件保留的所有格式都在渲染面板下边右部中间的弹出菜单里。从这里可以选择多数的图像或动画格式 (Figure 14)。
The default image type is Targa, but, since the image is stored in a buffer and then saved, it is possible to change the image file type after the rendering and before saving using this menu. 默认的图像格式是Targa(.tga)文件，但它是保存在缓冲区中的，在渲染之后或者被保存之前，都可以使用这个菜单来更改图像格式。
By default Blender renders color (RGB) images but Black and White (BW) and colour with Alpha Channel (RGBA) are also possible. Blender默认的渲染颜色是(RGB)图像(按钮在最下行)另外，同样可以选择黑白(BW)和彩色带阿尔法(Alpha)通道(RGBA)的图像。
Beware that Blender does not automatically add the extension to files, hence any .tga or .png extension must be explicitly written in the File Save window. 注意：Blender不会自动为文件添加扩展名，因此，任何的.tga或.png等扩展名都需要明确的写入文件保存窗口中。
Except for the Jpeg format, which yields lossy compression, all the other formats are more or less equivalent. It is generally a bad idea to use Jpeg since it is lossy. It is better to use Targa and then convert it to Jpeg for web publishing purposes, keeping the original Targa. 除了Jpeg格式会产生有损压缩以外，其他任何格式的文件都或多或少是相等的(质量)。一般使用JPG的有损压缩并不是一个好主意。使用更好的Targa可以转换成JPG用作网络发布又保留了原本的Targa。
Anyhow, for what concerns the other formats: TARGA raw is uncompressed Targa, uses a lot of disk space. PNG is Portable Network Graphics, a standard meant to replace old GIF inasmuch as it is lossless, but supports full true colour images. HamX is a self-developed 8 bits RLE (Run Length Encoded bitmap) format; it creates extremely compact files that can be displayed quickly. To be used only for the "Play" option. Iris is the standard SGI format, and Iris + Zbuffer is the same with added Zbuffer info. 总而言之，对于其他的相关文件格式如：TARGA raw是未压缩的Targa，会使用很多的磁盘空间。PNG是轻便型的网络图形格式，是老格式GIF的代替品，因为它是无损的，而且支持真彩色图像。HamX是一个自主开发的8位RLE格式；它所创建的文件极端的紧凑，可以很快速的显示。只能由“Play”选项使用它。Iris是标准的SGI格式，还有Iris+Zbuffer同样适用，它额外的包含了Zbuffer的信息。
Finally Ftype uses an "Ftype" file, to indicate that this file serves as an example for the type of graphics format in which Blender must save images. This method allows you to process 'colour map' formats. The colourmap data is read from the file and used to convert the available 24 or 32 bit graphics. If the option "RGBA" is specified, standard colour number '0' is used as the transparent colour. Blender reads and writes (Amiga) IFF, Targa, (SGI) Iris and CDinteractive (CDi) RLE colormap formats. For what concerns animations:
- AVI Raw - saves an AVI as uncompressed frames. Non-lossy, but huge files.
AVI Raw - 保存为未压缩的AVI帧，无损的，但是非常庞大。
- AVI Jpeg - saves an AVI as a series of Jpeg images. Lossy, smaller files but not as small as you can get with a better compression algorithm. Furthermore the AVI Jpeg format is not read by default by some players.
AVI Jpeg - 保存为一序列的Jpeg图像。有损的，文件很小，但也可以使用较好的压缩算法。另外，这种AVI Jpeg格式不能被默认的一些播放器读取。
- AVI Codec - saves an AVI compressing it with a codec. Blender automatically gets the list of your available codecs from the operating system and allows you to set its parameters. It is also possible to change it or change its settings, once selected, via the Set Codec button which appears (AVI Codec settings.).
AVI Codec - 保存为一个编码器压缩的AVI格式。Blender会自动从系统中获取你的有效编码器列表，并允许你设置一些参数，修改它的编码以及设定。选定一次之后，可以通过Set Codec再次打开设定窗口。
For an AVI animation it is also possible to set the frame rate (AVI Codec settings.) which, by default, is 25 frames per second. 对于AVI动画同样能够设定它的帧频，默认值是每秒25帧。
