Dear all, I am interested to build a dlm module to read/write avi files for idl (www.rsinc.com). Idl is a programming language for science. We are using movies to visualize our model outputs. I know how to add an external source to get more functionality. Unfortunately I have not found anywhere a description on how to make an avi file from scratch. Something like: open for writing put a frame close for writing open for reading get a frame at number close for reading At the moment I believe there are two general different possibilities: avifile which uses some win32 dlls and transcode. Hope you can help me with some documentation or links. regards Reimar Bauer
