We have been introduced to some capture preprocessing that is very important for creating optimized videos. We learned that VirtualDub configuration for capturing falls into four categories:
File settings
Audio Settings
Video Settings
Capture Settings
Moreover, we learned that before writing captured signals on disk they should be buffered for better disk I/O management and optimized data capturing. Also, with the help of some VirtualDub internal mechanisms called Spill System Setup and Multi Segment Capturing we can capture and save files with more than 2GB.
In the next chapter, we will learn how to use some filters to optimize captured data.
