Dalet Flex

New Features

Access to remote assets on Satellite Nodes without direct access from main Flex

The new Remote Assets and Remote Storage Resource functionality allows Flex in the main datacenter to work with managed assets that reside in satellite storage resources, without direct file access from the main site. A Storage Resource can be configured with a new parameter to define the satellite node name, and this value is inherited by assets imported through that Storage Resource. There is no direct access from the Flex main datacenter to these files; instead, Flex Core relies on a new dalet-filewatch-agent running on the satellite node, which has local access to the files and can verify their existence and size. HotFolder, Web Uploader, FSP and FFP workflows are the primary areas that benefit from this feature, enabling hybrid deployments where high‑resolution content remains on satellite locations while still being fully usable within Flex.

New workflow state - WAITING

Workflows that are at a task or wait node are excluded from the concurrent workflow limit, as they do not consume any server resources. Previously, these workflows were shown in the RUNNING state. This could be confusing for end users since the number of workflows displayed as RUNNING could exceed the configured concurrent workflow limit, even though some of them are actually waiting at a task or wait node. 

To address this, a new workflow state, WAITING, has been introduced and is currently visible in Flex CORE. Whenever a workflow reaches a task or wait node, its state is set to WAITING. This provides clearer visibility into how many workflows are actively running versus how many are waiting for a task to complete or for a signal to be received. 

Previously, workflows at a wait node or task node were included in results when querying for RUNNING workflows, since their state was set to RUNNING. With this change, such workflows will now have a state of WAITING and will no longer be returned when filtering by the RUNNING state. If your scripts need to include these workflows, update them to also fetch workflows with the WAITING state. You can adjust your search criteria to filter by both RUNNING and WAITING states.

Support creation of HEIC proxy images

To enable compatibility with all Apple devices, from this version of Dalet Flex, HEIC proxy images can be created using the JEF Transcode > Image Transcode (FMP) plugin.

Retrieve full hierarchy of collection 

A new endpoint has been added to Collection Service that retrieves the full hierarchy from root for a given Collection UUID. When set to true, the includeAncestors parameter, returns the parent hierarchy from top to bottom so it is no longer necessary to set a recursive API call to retrieve the hierarchy of a Collection.

Support retry and mulitpart for reading from S3 cloud storage

From this version of Dalet Flex, there is support for reading files in multiple parts for download, import, copy and move actions. The following system properties/environment variables must be set:

Add thumbnails for UDOs

A new REST API for creating thumbnails for User Defined Objects has been created. The API creates thumbnails only for Root UDOs using a KeyframeImageFile thumbnail sent in the API call. The image files are stored in the Keyframe Storage that is configured in the Account Metadata. You can also retrieve the details of the UDO thumbnail and its VFS location.

The new REST API supports:

POST /api/{pluralName}/{id}/thumbnail

GET /api/{pluralName}/{id}/thumbnail

Dalet Cut

New Features

In this release, the following improvements have been made in Dalet Cut.

Track type and numbering added

Track numbering type and names added to CUT Timeline tracks ((V-video <#>; A-audio <#>) in the left track control area. Track numbers are only displayed in Advanced edit mode.

When Trimmer is open, track numbers in Timeline are highlighted and can be toggled to “exclude/include” when sending media to Timeline.

Mouse Shortcuts for editing volume envelopes

You can set configurable mouse shortcuts for editing volume envelopes in the Cut Settings dialog.

To change the shortcut, double click on the entry and then press the required shortcut.

Lock individual tracks

You can now lock any track to exclude it from all editing actions. Toggle the padlock icon to enable/disable lock, the track shows slanting lines while locked. Saving an EDL will include the lock status. Locking is available in Storyboard and Advanced edit mode.

Improve audio keyframe volume envelope adjustment

Improve audio keyframe volume envelope adjustment to allow changing the envelope proportionally relative to keyframes constraints that exist  in the envelope.

Support display of individual mono tracks in Trimmer

When media is opened in Trimmer, you can now force mono presentation of source audio, so each channel is independently controllable.

Select Mono tracks in Settings>Trimmer>Trimmer Tracks Layout, the audio of media is always shown in separate mono tracks in Audio view, regardless of whether the audio is mono or stereo. Select According to the import media to display the audio based on its type. In this case, stereo audio is displayed in stereo pairs.

Support Color Adjustment effects

Dalet Cut now supports Brightness and Saturation effects. Access and enable the Color Adjustment Effect from the right side pane and use the sliders to apply the effect.

NOTE: Proxy and hires may have slight differences in colors and this might introduce differences in colors after color adjustments.

Save a frame as an image asset

You can now click the Extract frame icon in the Trimmer and save the image as an asset. You can set the Name and Format for the asset.

FlexXtend

New Features

Perform parallel check in from FlexXtend

To improve performance when working with media that is not registered in Dalet Flex, from this version of Dalet Flex, Check-in/Partial check on media assets is performed in parallel. 

While Check in is in progress, a table with process details, such as path, size, Job Id, Asset Id, workflow Id, Metadata, and status is dispalyed. Hover over the Path column to display additional metadata.

Ingest Portal

New Features

Improve Source Cards in Ingest Portal

These improvements have been made to improve the visibility and usability of Source Cards on Ingest Portal:

• A recording indicator is displayed

• Action buttons are hidden when you are not hovering over the source card.
• Longer source names are displayed in two lines or moved to two lines when hovering over action buttons 

Changelog

2026.1.0

• Fixed an issue where the Vantage transcode action failed on a Flex clip whose parent has file protocol with managed resource.  
• [Purge]: Fixed an issue where purge does not move the physical files and this error is thrown Cannot move physical files, the source location is referenced by resource.
• Fixed an issue where part of a rush file is not detected by partial checkin.
• Fixed an issue where some mogart assets are not visible or editable when project is opened on another computer. 
• Fixed an issue where there were daily master heap OOMs due to too much data being retrieved in an API GET {objectId}/variables/{variableId}/values{matrixParam:.*} call.
• Fixed an issue where in case Proxy Mode is disabled, FlexXtend imports .dlt instead of HR media when importing the project. 
• To prevent Audio files being missing when importing a project where partial checkin was done on audio track –Audio files are ignored on partial checkin.
