Mono Video Device | Unreal Engine 5.7 Documentation

The Mono Video device enables the ingest of individual video files as mono takes. If the video contains an audio track it will also be extracted during ingest.

Display Name: The name of the device as it will appear in the Devices list.
Take Directory: The path to the root folder containing video files. This folder can contain subfolders.
Video Discovery Expression: Tokens that can be extracted from the folder and file name to identify the take.

A visual example of the content expected to be found by the Mono Video device in the Take Directory is shown below:

Discovery Expression Tokens

The Video Discovery Expression is used to define the naming convention for video files in your takes. The available tokens are:


`<Slate>`	The slate name.
`<Name>`	The identifier for the camera.
`<Take>`	The take number.
`<Any>`	Any valid string.
`<Auto>`	Used without any other tokens to automatically identify takes based on the directory structure.

Tokens can be separated using the following delimiters: _-.\

When not using the <Auto> token, both <Slate> and <Name> must be present.

For example, consider the following take: MyTakeFolder/MySlate_MyName_SomeString-005.mov. If the Video Discovery Expression is set to the default value of <Auto>, the following tokens will be identified:


Slate	`MySlate_MyName_SomeString`
Name	`video` (the default value)
Take	`1` (the default value)

However, if the Video Discovery Expression is set to <Slate>_<Name>_<Any>-<Take> the following tokens will be extracted instead:


Slate	`MySlate`
Name	`MyName`
Take	`5`
Any	`SomeString`

In both cases, the extension .mov is ignored.
