When I use the stabilization feature for a video imported to a project and save it, then close it and re-open it the video show up in the preview black and won't play the music or voice.  If I go back into the video, which shows on the project, and click on stabilization as "none" it will then work.  any ideas as to why it won't work after saving. 

I have had some work after saving.  All taken on the same camera.
