Default Configuration [ VE 20.2 OG]

In order for VidiEditor to work with a VidiCore Starter or Team Edition in VidiNet, a set of specific configurations will be automatically applied to your VidiCore instance. The following is a complete list of the actions performed.

1 Metadata Fields
2 Shape Tag
3 User Groups, Roles and Metadata
- 3.1 Roles
4 System Configuration properties

Configuration of publish storages for VidiEditor Timeline publish must be done manually. Read more here: How to configure a storage for publishing of VPMS MediaEditor timeline render output

Metadata Fields

The automatic configuration will create the following metadata fields that are needed to operate VidiEditor's basic functionality.

Metadata Field Name	Data Type	index	Usage in MediaEditor
V3_Hidden	boolean	index	Set for item sequence/placeholder. Before export, set to true. After export, set to false.
V3_CollectionType	Dataset/string	index	This marks collections as a VidiEditor project.
ME_ProjectData	string	index	In collection (project): It is used to store all project version collection id and current project version collection id. In collection (project version): It is used to store what item in the project bin.
ME_Timeline	string	noindex	Timeline data describing the settings and composition made in the VidiEditor timeline.
ME_LockUntil	date	noindex	Expiry date time for the project lock.
ME_LastEditor	string	noindex	The last user that opened the project which also lock the project.

Shape Tag

In order for content (items) to be usable in VidiEditor preview (Source and Timeline Player), the items must have a shape holding a video format supported for the VidiEditor's streaming server (See section VidiEditor Proxy Formats also).

The automatic configuration will create a shape tag named “ME_proxy_mp4_360_8ch”, and add it to the list of allowed shape tags in the “me-user” user group key-value metadata. This shape tag is the recommended format to use for the proxy copy of video assets. It can be adjusted or another shape tag can be defined as usable as long as the related video files fulfill the requirements for the proxy file format.

Items in VidiCore must be transcoded into a shape valid for use with VidiEditor in order for content to appear in the VidiEditor content browser. The shape tag name must match a configured parameter for the

Furthermore a shape tag named “ME_AudioOnly“ for audio only files will be added upon default.

User Groups, Roles and Metadata

The automatic configuration will create a User Group called “me_user” and the Vidispine “admin” user account will be added to this group.

The User Group will be configured with the following Key-value metadata use for basic configuration. The effect is described in following table:

Key-value metadata	Value (Default)	Usage in MediaEditor
ME_ProxyShapeTag	ME_proxy_mp4_360_8ch	Proxy shape tag to filter for in VidiEditor search. Only items with a matching shape will appear in search results. Comma separated list is possible.
ME_ProjectDeletionLockExpiry	72	VidiCore deletion lock duration for VidiEditor Project (in hours). Set “INF” for infinity, which mean this project will not allowed to delete at all until date 9999-12-31T23:59:59Z Leave it empty, if no deletion lock should be set.
ME_PublishShapes	__mp4	Supported publish shapes, separated by comma "," Defines the transcoding presets that can be chosen by the user in the publish dialog.
ME_ProxyAudioShapeTag		This is used for searching and importing audios
ME_RenderEngine_OutputFormat		Shape tag used by render engine player to stream video output format
ME_SupportedFrameRate	25, 30, 29.97	Supported frame rates for VidiEditor projects. The user can choose time base on Timeline creation form the configured list. Media must match this time base to be usable in the timeline. Supported values: 25, 30, 29.97, 59.94
ME_UsePresignedPath	true	Used to define how VidiEditor shall access files. Must be true when VidiEditor is operated in VidiNet.
ME_ConcurrentSession	[{"Username":"admin","SessionToken":"zPvvmF0txqRInkFt4DPkJzY8m/sXtK9eca9wseDp","ExpiryDate":"15/7/2020 3:15:23 AM"}]	List out the concurrent sessions
ME_DirectOutShapes		supported direct out shape for audio. Separated by comma ","
