I discovered that Windows Photo has a pretty good basic video editor hidden in it.
My wife used it to edit a family video. Then she wanted to save the project (clips and project file, not just the final product) to USB drive.
Photo only gives you one option: Save to OneDrive. The claim is that other OneDrive devices running Photo will then be able to see the Project.
However, careful inspection of OneDrive yields no file with the title of the project and nothing that obviously looks like a video editing project file.
Does anybody know how they pulled this off and where they have hidden the project information? It can't be buried in the Registry, because that wouldn't transfer through OneDrive.
回答1:
There were two reasons I was looking into this.
1) For a video project, set the duration for all the photos in a storyboard to something other than the default. (Why isn't this built in?) and;
2) On another project, reset the duration that I'd set on a bunch of photos so it could auto sync with music.
So, I looked into this a bit, and for reference the data is stored in an Sqlite database called MediaDb.v1.sqlite located by default here (replace YOURUSERNAME) C:\Users\YOURUSERNAME\AppData\Local\Packages\Microsoft.Windows.Photos_8wekyb3d8bbwe\LocalState
You can load the database using an Sqlite reader like DB Browser however you can't update it because it contains an unrecognised database collation (column character set) called NoCaseUnicode which you can about more here
There are others who are reporting similar problems trying to access this file.
