Thanks everyone for the input and I think it is clear that I need to edit the metadata of the AVI’s, ideally with the 4CC Code Changer app, but this appears to only be a PC app. Does anyone know how to convert the AVI’s once you have them in the Mac world? This really seems to be a flaw in the workflow as I am sure I am not the only person who works with clients across platforms? At any rate, I really appreciate the responses and help on this. Thanks.
