Dalet Flex

New Features

Support asset status and status flow management in Dalet Flex

Dalet Flex 2025.4.0 introduces the infrastructure in Dalet Flex for supporting asset statuses and status flow. Currently asset status and lifecycle management is only supported via API.

API documentation is available here:

The current workflow is:

Create Status → Create Status Flow → Create Variant with Status Flow ID → Create Assets Associated with Status Flow Variant

Create Status: Each Status has a unique name, unique abbreviation, description, color. The created status has a unique id.

Create Status Flow: Each Status flow has a unique name, sets the Start Status (single value) and End Status (can be multiple values) and all supported transitions between source status and target status. Once created the Status Flow has a Status Flow ID.

Create Variant with Status Flow ID: Create a new variant with the Status Flow ID or assign the Status Flow ID to an existing variant.

Create Assets Associated with Status Flow Variant: Create assets and associate them to the variant with the status flow.

Permissions for working with the status flow are assigned via the Status Flow object in the Role for User(s) and or Groups(s). The permissions control the creation/update/ deletion of statuses and status flows, you must have edit permissions on an asset to change the status of assets according to the configured status flow. If you do not have appropriate rights, an error is thrown.

Events of type Status Flow are indicated using this icon, .

Support Extract EXIF Technical Metadata using a plugin

From Dalet Flex 2025.4.0, the Extract Image Technical Metadata plugin has been updated to include setting a configuration option to support the extraction of image technical metadata using Exiftool or Mediainfo engines. If one of these engines is specified in the Extract Image Technical Metadata action, JAE sends a request to FSP to use the defined engine to extract technical metadata.

The metadata extracted using this action is stored in Arango database in the extendedTechnicalMetadata field for the asset.

In the File tab in Flex CORE, the Extended Technical Metadata section is added and it displays the name of the field and the UUID for the raw metadata stored in the database. This information is not displayed in FlexMAM.

You can retrieve the information via the asset API with includeDetails=true.

For example

If no engine is specified, the Extract Image Technical Metadata action remains unchanged and the standard technical metadata is extracted and populated in Flex Core and in FlexMAM. To retrieve the standard technical image metadata, you MUST run the extract engine with NO Forced Engine configured.

Support FCPXML import and render to high res

Media assets are delivered to Dalet Flex in different formats from different sources, for example from NLEs. From version 2025.4.0, Dalet Flex supports importing an FCPXML using the Import Edit plugin in the Import action type and automatically creating a Flex AFF for use in Flex Cut. Once you have completed your edit you can render your project to a hires file that can be distributed on different platforms.

To support this workflow, a new option, Create Dalet Cut Edit, has been added to the Import Edit plugin. In addition, you must set the Output AAF parse tmp file to Yes.

To support this functionality the dalet-cut-service has been created.

Support extracting subtitles from a Flex Cut AFF asset

Dalet Cut supports importing ttml subtitles on to the Timeline and allows you to edit and create additional subtitle segments. From this version of Dalet Flex, once you have completed working on your project, you can conform your project and either extract only the subtitles as a ttml file or create a new media asset and a ttml file.

To extract the subtitle as a ttml file:

In Extract plugin type, select Extract Subtitle and in the configuration, set the Output Format to ttml. Select the aff asset and run the Extract Subtitle job.

To create a media asset and extract the subtitles as a ttml file:

In the Transcode action type in the Conform plugin, a new option Extract Subtitle has been added. When Extract Subtitle is selected and a conform action is run on an AFF asset, a media file is created and a ttml file is extracted and a Subtitle asset is created. The subtitle asset is created as a child of the asset which the Conform action was executed on.

Flex Cut supports adding subtitles with media

From Dalet Flex 2024.11.4, TTML format subtitles associated as children of a Flex asset are automatically imported into Flex Cut in a dedicated CC track when the parent asset is added to the Timeline. You can edit the CCs in the track using the CC panel and all changes, including font and size, are saved as part of the EDL project. When the project is reopened in the Timeline all the saved changes are available.

Monitoring files on a playout server storage

In a broadcast environment, media files are uploaded to target storage locations on video servers for playout. To ensure that content is delivered as planned, it is vital to have real-time monitoring of the state of the media files uploaded to the video servers. From this version, 2025.4.0, Dalet Flex supports file presence monitoring on targeted storage locations. This ensures that files published to specific storage destinations are automatically tracked, enhancing reliability and providing visibility of the status of exported files.

NOTE: Currently this has been validated for static files uploaded using FTP to a Dalet Brio server.

When a file is published using the Video Playout Publish plugin, hotfolder service monitors and registers its state: Transferring, Online, Offline. If the file is unpublished or becomes unavailable, hotfolder service monitors the changes and updates its state. The default supported state transitions are:

TRANSFERRING -> ONLINE

ONLINE -> OFFLINE

OFFLINE -> ONLINE

ONLINE -> ONLINE

OFFLINE -> OFFLINE

TRANSFERRING -> TRANSFERRING

Additional monitoring information, such as the file creation time and last modified time are also recorded by hotfolder service and are written to the database. A file can have a single state at any one time. Currently the monitoring information is not available in the GUI and can be retrieved by calling the enterprise API syndication monitoring endpoint: /api/assets/$ASSET_ID/syndications/$SYNDICATION_ID/monitoring.

Support extracting thumbnails for existing markers/annotations

From Dalet Flex 2025.2.0 it is possible to auto generate and store thumbnails for markers/annotations using a System REST Extract Thumbnail action.  From Dalet Flex 2025.4.0, the JEF Extract Thumbnail plugin has been created. The plugin includes a configuration to support extracting thumbnails for existing markers/annotations.

In the Extract plugin type, select the Extract Thumbnail plugin.

In the Configuration tab, select the System REST Transcode Resource, (Flex Stream Processor). When you run the action manually, you must set timecodes that thumbnails should be extracted for. You can use the expression @@timecode@@ so the timecode of the execution context is used by the action by default.

To extract thumbnails for existing markers/annotation, create an Extract Thumbnail action with Extract all thumbnail set to true and execute the action on specific assets from FlexMAM. In this case you do not have to set the timecodes.

NOTE: Thumbnails are stored in the Account Folder configured in the Account metadata.

Improve search to support accent-insensitive and apostrophe-formatting-insensitive searches

To improve the search functionality in Dalet Flex to support accent-insensitive and apostrophe-formatting-insensitive searches, the analyser configurations in the index configuration templates defined by flex-indexelastic-service has been updated to use ASCII folding filter.

To use this in Dalet Flex 2025.4.0:

The Consul KV flex/shared/featureToggles/search/asciiFolding must be set to true
All instances of flex-indexelastic-service and flex-searchelastic-service must be restarted
A full reindex must be initiated and completed successfully.

Additional languages added

To improve user experience and accessibility, the following have been added as official languages in the FlexMAM:

Italian 
Spanish 
German 
Hebrew

Additionally, the existing Arabic translation has been updated. These additions enable users from diverse linguistic backgrounds to fully utilize the platform's features and functions.

API method to retrieve the ids of all assets with a syndication matching some criteria

To get all Flex assets having a specific syndication (in a Dalet Pyramid container), syndication-related matrix parameters have been added to the GET /api/assets "List Assets" API. Can filter by matching:

Syndication provider (not case sensitive)

Allowed values: "FLEX", "RSS", "VIMEO", "OMNEON", "TWITTER", "YOUTUBE", "VELOCIX", "KALTURA", "FACEBOOK", "JWPLAYER", "BRIGHTCOVE", "DAILYMOTION", "DALET_PYRAMID_MEDIA_BIN", "DALET_PYRAMID_SCRIPT", "DALET_PYRAMID_RUNDOWN", "DALET_PYRAMID_EDL", "DALET_XTEND_PROJ", "VERITONE", "VIDEO_PLAYOUT_MONITORED_SERVER"

Syndication system id (case sensitive+exact match)
Syndication resource id
Syndication embedding id.

For example: To search by syndication provider with all options: {host}/api/assets;syndicationProvider=DALET_PYRAMID_MEDIA_BIN;syndicationResourceId={rId};syndicationSystemId={sId};syndicationEmbeddingId={eId}

Improve tag management from Flex SDK

To enable developers to integrate tag management seamlessly within their SDK-based workflows, improving automation, usability, and consistency with the API, additional methods for asset level tag management have been introduced to Flex SDK.

Supported object associated tags - getTags(assetId),addTags(assetId, tags), deleteTag(assetId, tag), deleteTags(assetId, tags).
Add support for Enterprise to allow deletion of multiple associated tags from objects.

Fixed Issues DaletFlex

REST API: Fixed an issue where updating action metadata and asset metadata with expression value with isExpression as false was not working properly.
Fixed an issue where configurations in nested child options were not being saved well for action plugins, for example, it was not possible to save the configuration Parent Asset ID for action Import plugin Asset Import.
Fixed an issue where it was not possible to add fields from metadata definitions created in different accounts to display templates even though the metadata definitions are visible to the current account.
Fixed an issue where a JEF script to migrate metadata backed by taxonomies into timeline annotations stops running and hangs and JAE service seems to hang if it loses connection to the Taxonomy service. See this article for additional configuration information.
Fixed an issue where Extract Waveform plugin is not generating a VOL file correctly for video assets.
Fixed an issue where moving large files (2TB+) was failing.
Fixed an issue where sequence preview in FlexMAM was failing for Mpeg-Dash proxies.
[FlexCORE] Fixed an issue where the Account’s theme theme was not created on a new master account (applicable for fresh deployment only). For similar problem on existing environments, please contact Customer Services.
[Technical Data] Fixed an issue where Format Variant information was not displayed, specifically for audio only files.
Fixed an issue where Add & Remove ACL Plugins throw NPE when non-marked required configuration field ACL Mode is not filled.
Fixed an issue where Add & Remove ACL Plugins throw NPE when non-marked required configuration field target (group or user) is not filled.
Allow FQL to filter date fields as negative numbers so you can search using negative millisecond timestamp values (for dates older than 1st Jan 1970).
Fixed an issue where the logo was missing Flex Web uploader. Issue fixed by adding additional logic to find account using host name if accountName is not found.
Fixed an issue where the styling of display templates was updated to accommodate larger metadata infos. Previously metadata fields with large amounts of information were truncated in display templates for tile view.
Add support to import .ts transcode outputs from Launch Vantage Workflow plugin.
Fixed an issue where Import & Copy jobs are failing with the error Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect). Issue was fixed by fixing the auto-retry for jobs in the case of StaleObjectStateException.
Fixed an issue where JEF Wait for Script with option Update Workflow Variables = YES overwrite the values of the workflow variables because FlexContextVariable is matching String as a date type variable on receiving WorkflowContextVariable in JEF Wait for Script. For the fix to work set workflow variable use_lenient_for_workflow_date_variable_conversion to false, by default it is true.
Fixed an issue where Clipbin pagination was not working correctly.
Fixed an issue where the wrong clip asset count is displayed in the Asset Manage page.
Improve the ACL Update event to capture the full information about the update in the mode, the old mode and the new mode. For example, userAclModes: 1017:READ_ONLY updated to READ_WRITE,1016:READ_WRITE updated to READ_ONLY and groupAclModes: 1023:READ_WRITE updated to READ_ONLY.
Fixed an issue with intermittent advance frame freeze for 23.976 fps video.

Fixed an issue where searching through Enterprise with metadata criteria generates FQL clauses which are potentially ambiguous and return incorrect results.
Fixed an issue where format information such as width, height and format is not being shown in a display template for image assets. Issue fixed by making image height, image width, image format available in Technical section of template configuration. Also added an option to filter for image format.
Fixed an issue where fields in columns are overlapping each other the in right panel in FlexMAM.
FlexMAM: Fixed an issue where selecting a saved search to display Marker result was not loading properly unless the page was refreshed.
FlexMAM: Fixed an issue where search using is/is not filters with no set value was not working properly and required a browser refresh.

JEF SDK mistranslates Date values when delegating to the Enterprise API with matrix parameters (e.g. lastModifiedFrom, lastModifiedTo). Fix ensures that a 24hr 0-23 hour value is used.
JEF SDK: Fixed an issue where JobService.getJobs() does not correctly map the `includeVariables` parameter through to the Enterprise REST API call.
[FFP] Fixed an issue where copying data spread in multiple files from AWS to OVH was failing with this error A conflicting conditional operation is currently in progress against this resource. Issue solved by ensuring that the object's parent folder key is only added once when encountering a source folder rather than for each file in the folder.
