If an image under a CC-SA license gets used in video - must video be CC-SA? I want to use an image under CC-ShareAlike in my video. The image has not been changed, however I have applied a slight zoom &amp; pan motion to the image in the video. The video contains other images which either have expired copyright or are under CC but not share-alike. 

If I use the image under CC-ShareAlike in my video, does that mean I have to make my video CC-SA as well?

thanks,
Yes, that's the core condition of the CC-ShareAlike license. Any derivative or work that contains the image has to be distributed under the same license for the entire video. Even if you create a long video with only one image that is licensed under CC-SA, you will have to use the same license. Using a different license would be a violation to the terms of use. This makes it complicated to use videos and images that were distributed under diverse licences, which is the main disadvantage of the CC-SA license.
