2.5.1 Growing File Support (v.5.x)

Just Control supports growing files within the Library, Workbench, and Preview windows. Growing Files are indicated by an italic font face style within the Library and Workbench area.

Just:Live:

Once a Growing File gets played out, the endpoint of that clip will be automatically updated.

Just:Play:

Once a growing file is dropped into the rundown, it will take over the current length but will not grow further until the recording has stopped. Until then, it will behave and look like a Placeholder element.

Growing File Update Parameters:

In order to cope with different storage systems and file types, there are two settings (Apple “Terminal” commands) available, which can be used to adjust the growing file behaviour within the Just Control application:

# Growing File Update value
# Default value: 5
defaults write com.toolsonair.Just-Control TAKMDSGrowingFileUpdate -int X
# Growing File Check value
# Default value: 2
defaults write com.toolsonair.Just-Control TAKMDSGrowingFileDelay -int X

The “TAKMDSGrowingFileUpdate” value defines the interval (in seconds), in which Just Control checks for new file durations. So, by default, the growing file will be updated every five seconds.

The “TAKMDSGrowingFileDelay” value defines how many times Just Control checks if the file is still growing. By default, Just Control checks the “TAKMDSGrowingFileUpdate” value twice and if there is no update, the file will be identified and displayed as closed.

We recommend testing such Growing File workflows in every detail, before using them in production, as every storage system can act differently and especially MXF files may require adjustments of the given default values.
