--- title: ZEN Master 12 August 2025 Release Notes slug: zen-master-12-august-2025-release-notes docTags: createdAt: 2025-08-26T14:05:06.347Z --- ## New Features The following new features were implemented in this release: ### SPTS Multiplex Sources: - A new ZEN Master Source type is included, to support the Broadcaster’s SPTS Multiplexer (requires Broadcaster v19). - The result is a new SPTS stream with the interleaved PIDs. ![SPTS Source](https://api.archbee.com/api/optimize/amUtKWPrNQCS-26DKyGuI-lggW6hFV7nYR39_anRCyT-20250826-140904.png) - The User chooses the primary Source and lists the PIDs they wish to keep. - PIDs are specified with a comma separated list: - source\_pid, source\_pid - and can be optionally mapped with a ‘:’ symbol: - source\_pid\:target\_pid - PIDs must be entered, leaving the PIDs blank results in a Broadcaster error. ### Source stream information is now displayed in Target details - The Targets Stream Tab now displays the transport stream tree alongside the thumbnail. ![Source Stream for Target](https://api.archbee.com/api/optimize/amUtKWPrNQCS-26DKyGuI-It6Ymx1Kmac5GhxEBhhaQ-20250826-141306.png) ### Added option to ignore PIDs in TR101/CQA monitoring. ### Logo insertion on Transcode Profiles ![Logo Insertion in Transcode Profile](https://api.archbee.com/api/optimize/amUtKWPrNQCS-26DKyGuI-TysdIBlzK-Ae-d8_Bt4Aj-20250826-141551.png) - Logo can be enabled, via the transcode profile. - Its position (in pixels or percentages) can be configured along with the alpha channel value. - The logo is burned into the resulting video. ### Added 'External Link' to Live Events ### Live event objects can now include an external link. - The feature allows event creators to link an event to an external system for additional event metadata and scheduling information etc. ![External Link for Live Event](https://api.archbee.com/api/optimize/amUtKWPrNQCS-26DKyGuI-RSL5itoKVoXUoH_qDm7D9-20250826-142133.png) ### Broadcaster version upgrade/downgrade from ZEN Master - Manual Broadcaster upgrades can now be initiated from directly within the ZEN Master interface. - The installation tool is opened via the Broadcaster’s top right menu: ![Upgrade/Downgrade Broadcaster](https://api.archbee.com/api/optimize/amUtKWPrNQCS-26DKyGuI-XUieW5hojnyEK2ZTJgLvs-20250826-142701.png) - Once opened, the User can select a new version from the available list (as managed in the Customer Portal). - Hitting ‘Install’ uploads the version installer and initiates the upgrade. ![Select New Broadcaster Version](https://api.archbee.com/api/optimize/amUtKWPrNQCS-26DKyGuI-EuuD6fXUhbduWaQbRMIW8-20250826-142929.png) ## Improvements and Changes ### New monitoring rules for Low Video and Low Audio bitrates - Low bitrate thresholds are now definable in the event profile. ![Set Source Low Bitrate Thresholds](https://api.archbee.com/api/optimize/amUtKWPrNQCS-26DKyGuI-spKauPVSU5KpzODzwvcH7-20250826-143458.png) ### New monitoring rules for UDP send/receive errors on Broadcasters. ### Source selection in forms now uses full tables with advanced filtering. ### Added lifecycle logging to Tags. ### Added SAR/DAR, Language, PTS, Audio Channel info to stream information tree. ### Diagrams will now consolidate Targets into a single box when there are many of them. ### Where it makes sense added copy to clipboard button to table cells and details tiles. ### Added option to show Targets on Source diagrams and downstream objects tab. ### Reworked SRT passphrase to match SRT functionality. ### Added SCTE-35 logging to Failover Channels. ### Added Pass all PIDs toggle to Transcode Sources. ### Added DTS/PCR delta configuration to NDI Sources. ### ZEN Master will now log Broadcaster versions on connection and change. ### Renamed Multiplex Sources to MPTS Multiplex. ### Improved Failover Source/Channel Max bitrate calculation and added an override option. ### Updated Max Bitrate monitoring: - Use actual bitrate data instead of Broadcaster status to alert on Bitrate > Max Bitrate. - Alert on Max Bitrate too high (Max bitrate >= 40 Mbps and Actual bitrate \< Max Bitrate / 8. ### ZEN Master will now alert for invalid Broadcaster configuration of MPTS Multiplex Sources. ### Added x264 option to NDI Sources. ### Added many missing configuration options to details and info panels. ### Added raw SCTE-35 HEX column to SCTE-35 log tables. ### Implemented SCTE-35 support in Kafka. ### Implemented Error Concealment on all relevant Source types: - Zixi Pull, Inter-cluster, Failover, Rist, Srt, Udp/Rtp, PID Map, Demux, SPTS/MPTS, Mux, HLS, RTMP. ### Frame Thinning is now a boolean configuration: - API change - existing field is now treated as boolean instead of a number. - For v18 Broadcaster the latency is set to 1000ms. ### Error message polish. ### Frame Thinning is now a Boolean setting to match v19 Broadcasters: - On Broadcaster version 18, this will default to 1000ms. ## ESNI & ESAM ### ESAM - No longer trying to switch on PTS when there is no PTS. - Fixed POIS latency not doing anything. - Added Error Concealment support to POIS loopbacks. - Cleaned up 'no outputs' found logging. - Updated config template file with more realistic defaults. ### ESNI - Reworked switch on PTS to apply policy on PTS then switch. - Implemented full support for ISO 8601 durations. - Added missing @duration to Apply tags in Media GET response. - Added version endpoint. - XMLNS no longer required in 224 XML document. - Targets will now prioritize Channels with matching Target Broadcaster settings. - Use Audience ID and Audience namespace elements to math ZEN Master Targets.
