This is a step by step tutorial for writing a simple video processing application in Delphi or C++ Builder VCL by using VideoLab.
The steps are exactly identical in Delphi or C++ Builder versions 5 to 2007.
There is no code writing necessary to complete this application.
There is no need to know Delphi or C++ Builder in order to create this application.
The steps bellow are captured using Delphi 2007, however they are identical in C++ Builder and older versions of the products.
The tutorial covers the following steps, which should take less than two minutes:

TVLAVIPlayer component.
2. Add a TVLFixedFilter Component to Your Application's Form:
2.1. From the VideoLab tab of the component palette drop a 
TVLFixedFilter component.
3. Add an TVLAVILogger Component to Your Application's Form:
3.1. From the VideoLab tab of the component palette drop a 
TVLAVILogger component.
4. Add 2 TVLImageDisplay Controls to Your Application's Form:
4.1 From the VideoLab tab add 2 
TVLImageDisplay controls to the form.
4.2 Arrange your form to look like this:
