Sorry if my english is not good. I'm building a program on Windows that take in a table and draws chart, text and some animation effect(text running in bottom of screen). The program must export that to a .avi file. How can i do that?Do you know any library that can directly manipulate a .avi file like draw on a frame. Or a library can convert a list of pictures to .avi file.
