From Michael Caracena:
AVI Constructor Pack is a collection of software tools for Windows 95, 98, Me, NT, and 2000 that can assist you in creating AVI files. It contains AVI Constructor, AVI Compress, AVI Merger, AVI Extractor, and AVI Speed Adjustor. Both AVI Constructor and AVI Merger support the creation of 2-bit, 16-bit, 32-bit, 256-bit, high, and true files. You can quickly preview your animation in its main window before you build the AVI file. You also can auto-capture (capture an images from the Clipboard while you're working in another imaging program).
