Media Player Editor is not saving the media texture right after closing it

Alright, Steps:

  1. I’m trying to import a new MP4 video format to the Unreal engine 4.14. and use it as animated Main_Menu Texture.

  2. I dropped the video using Windows 10 Explorer to My Project/Content/Movies Folder where it should be placed to work properly.

  3. Renamed the imported video to Main_Menu.

  4. Created advanced asset ‘’ File Media Source ‘’.

  5. Opened " File Media Source " and selected File Path : My Project/Content/Movies/Main_Menu.mp4.

  6. Created advanced asset " Media Player " and checked “Video output MediaTexture asset” box on .

  7. Opened the New " Media Player " and inserted Media URL correctly from Media Library.

  8. While leaving the Media Player without closing or saving it the Media Texture remains as a working media texture.

  9. Saved file and closed the Media Player window

  10. The Media player’s video Texture returned into Empty (Black) and it refused to save or save as Media texture.
