Summary

In this chapter we learned that there are two sources for video: analog and digital. We also learned that the capturing equipment can be divided into internal and external devices. Generally, external devices are expensive and powerful because capture and compression tasks take place at the hardware level. These, however, allow less control over the format of the captured video. Internal capture cards are usually cheaper and exercise more control on the video format since some application like VirtualDub is used for capturing and compressing captured video. Finally we discovered that we can do some hard disk and Windows optimizations to decrease dropped frames during capturing and get a smooth video.
