cuiyunpeng@yahoo.com.cn 我相信你一定会被这篇教程所的缜密的思维、精致的叙述所感染！
This is a very simple tutorial demonstrating how to take 2D video footage and composite a 3D animated object in the scene. I'm not going to go into every specific MAX feature and option used, Instead I'll be concentrating more on the actual process and flow of work and files.
这是一个关于如何在2D视频脚本中混入3D动画物体的简单教程。教程不涉及3Dmax的详细功能，而是注重与实际的工作程序。
1.Convert your video sequence to individual TIF files.
1. 把你的视频序列转换为TIF文件。
As we have discussed earlier when working with effect we want to keep file quality as high as possible, therefore JPEG's are not the best medium for image storage. In this tutorial we'll be using TIFF files or TARGA fileswhen we require an alpha channel. Take this TIFF sequence and store it for later.
我们要尽量保持文件的品质，所以JPEG等格式不在考虑范围之内。自在这个教程中，当需要alpha通道时我们向选用TIFF或TARGA格式。把视频转换成TIFF序列以备后用。
Unless you're using a very high end machine you're not going to want to be dealing with large amounts of files while compositing, so take one frame of your sequence and keep it handy. Store the rest of the files somewhere else for later. Keep one frame as a proxy. Make sure you keep your files and directories neat, compositing can be a logistical nightmare with the amount of files you'll be dealing with. A bit of planning and neat directory structuring can save you a lot of headaches later on down the line.
除非你使用的机器非常高端，否则在合成时不能处理大量的文件。所以从你的视频序列中选出一帧并放在容易调用的地方。保持一个静止帧作为代理。一定要保持你的文件和目录清晰明了，因为如果要处理大量文件的话合成操作将会苦不堪言。进行一点计划并保持文件组作执整洁会在后期避免许多麻烦。
