We are having issues importing mp4 video files. We are using Presenter 9 and Office 2010. I have no issues inserting and using the videos, but my co-worker get an "Error Encountered in Source File" message when inserting the same mp4 files. When previewing or publishing, the video does not display. Any ideas on what causes this and how to fix?
After talking with support, it was determined that my co-worker did not have the correct codecs. She installed QuickTime to solve the problem.
