Hello Adam, Your problem may be from how you are using WRITE_VIDEO for not being able to play videos in Power Point. Try using the example on the following link, which uses IDLffVideoWrite and successfully works : http://www.exelisvis.com/...IDLffVideoWrite.html Additionally, if you check the documentation regarding WRITE_VIDEO, it is specified that WRITE_VIDEO is a wrapper for IDLffVideoWrite. I would recommend reading the documentation for more information (http://www.exelisvis.com/...s/WRITE_VIDEO.html). Also, in the future it may be best if you post questions which are specific to IDL under the IDL folder in the forum. They will likely get answered more quickly in there. Hope that helps!
