Hello Everyone, I have a question about the video container format and codecs which Blender uses.
Blender Chairman, Ton Roosendaal suggested I post it here. He said, "I think it's a valid question, but it should be discussed and reviewed in public." So here it goes... Question 1: Is the AVI *container* format which Blender uses proprietary? My research suggests that Microsoft's AVI container format is based off of the unpatented RIFF format. Further, the U.S. Library of Congress' website for digital preservation indicates that Microsoft probably does not hold/enforce any license or patent claims on their AVI container format. However, a Microsoft Community web page says that a commercial software developer would need Microsoft's permission to include AVI container support. Question 2: Are any of the codecs Blender uses with the AVI container, (either for importing or saving) encumbered by patents or commercial licenses? Do I need to be cautious of which codecs are used when importing or saving if I want to create and distribute a for-profit video?
