    • As introduced in version 6.6.7, duplicate layer names are automatically renamed to default values (e.g., Layer 1). Also leaving the name field empty, in the layer dialog, will change the layer name to the default name.

    Known issues and limitations

    • Not recommended for use with Dataton WATCHPAX 40 (product number: 3364A).
    • Before updating Dataton WATCHPAX (product number: 3360 ) or WATCHPAX 2 (product number: 3362) media players to WATCHOUT version 6.6.7 or 6.7 or higher, please ensure that the unit’s hardware image version is version r23 or higher for WATCHPAX, and r33 or higher for WATCHPAX 2. If the image version is older, the unit will stop working and a “license key not found” error will be shown after the WATCHOUT version is updated.

      For more information on how to update the hardware image, please contact your local partner or Dataton.

    Dataton WATCHOUT® version 6.6.7

    Released October 27, 2021

    This release contains the following fixes:

    • Previously, a DMX recording file was not properly transferred to the display cluster if the system was in live update, resulting in no file found. This has now been resolved.
    • An issue with newer NVIDIA drivers (version 461.x and later) affecting conversion to NV12 color space has been fixed.
    • Dynamic Image Server now supports TIFF files with newer version format.
    • Duplicate layer names could cause erratic behavior and are now prohibited. Duplicate layer names in older shows are automatically renamed to default values (e.g., Layer 1) when opened in version 6.6.7.

    Dataton WATCHOUT® version 6.6.5

    Released March 2, 2021

    This release contains fixes regarding automatic refresh, display masks and toggling between window modes.

    • Previously WATCHOUT could crash when “Masked by Layer Above” was selected in a virtual display cue. This has now been resolved.
    • Two issues related to the “Refresh Automatically” command on the Media menu have been resolved. The automatic refresh did not apply to MPCDI and imported display setups, or when multiple files were modified at the same time.
    • Images no longer become pixelated when WATCHOUT display software is toggled between fullscreen and window modes.
    • If you delete a display mask it is now removed from the production preview.

    Dataton WATCHOUT® version 6.6.4

    Released December 18, 2020

    This release adds fixes related to MPCDI (Multiple Projection Common Data Interchange), setIP and display masks.

    • An issue concerning display masks has been resolved. Previously, when two output displays went online for the first time, the display mask was not applied.
    • WATCHOUT no longer crashes if the MPCDI warp mesh has NaN (Not a Number) values.
    • An NDI stream was not always recognized by a Dataton display device, for example a WATCHPAX, if the IP number was set/changed by using the “setIP” command in the startup script. This has now been fixed.
    • Consolidating a show with MPCDI now works correctly. In earlier releases, if you chose to consolidate a show that used the MPCDI feature, the resulting file could not be opened.

    Dataton WATCHOUT® version 6.6.3

    Re-released as version 6.6.4

    Dataton WATCHOUT® version 6.6.2

    Released August 31, 2020

    Dataton WATCHOUT® version 6.6 

    Released February 21, 2020 

    This release includes a major version update of NewTek NDI® (4.1) as well as significant improvements in audio latency and playback. It also includes bug fixes and improvements to existing functionality. 

    Improvements and fixes

    • It is now possible to rotate RTTrPM data (as used by CAST BlackTrax systems) 90 degrees to simplify floor projections.
    • The real-time tracking origin can now be offset relative to the WATCHOUT origin.
    • Tracking input positional components are now in WATCHOUT pixel units.
    • All tracking inputs now share the same origin in order to maintain the correct relation between tracked cues.
    • The Test Connection button now works correctly after changing IP in the display dialog.
    • The stage view direction (Front, Top or Left) is now preserved in the show file, and properly restored when loading the show.
    • A bug has been fixed which could cause broken frames during hardware-accelerated video playback.
    • Cancellation of media import now works as expected.
    • Improved image sequence playback on auxiliary timelines when triggered from the production interface.
    • Output cues now respect layer conditions.
    • The production software could run out of memory while importing large WAV files, this has now been fixed.
    • The WATCHOUT splash screen no longer appears while pushing new media in Live Update mode if a -NoLogo command has been specified.
    • A bug regarding usage of digits in tracking input names fixed. A memory leak related to H.264 and WAV playback has been fixed.
    • The production software could crash while initializing ASIO devices, this has been addressed.
    • Inconsistencies in WATCHOUT logging fixed.

    Known issues and limitations

    • Remote access is not available from right-click menu when in offline mode.
    • Leaving an NDI media cue might cause overall playback to stutter momentarily.
    • Production software will crash if a deleted Virtual Display cue is re-added using undo.
    • The production software may crash if more than one display is connected while the show-cache is being rebuilt.

    Dataton WATCHOUT® version 6.5

    Released October 1, 2019

    This version enables use of SDI (Serial Digital Interface) as an output on select Dataton media servers. It also includes improvements to existing functionality and bug fixes. 

    New in version 6.5

    • SDI support on select Dataton media servers. 
    • Ability to edit command-line options of display software through File menu on select Dataton media servers. 

    Improvements and fixes

    • It is now possible to set a different Stage Size than resolution for 3D Mapping Projectors. 
    • Multi-editing of dropdown menu items for displays now works correctly. 
    • File transfer and media analysis speed to server is now faster and no longer dependent on the number of screens/resolution. 

    Known issues and limitations 

    • The production software occasionally fails to establish a remote desktop connection to a media server if the server has multiple high-resolution displays connected ot it. Re-trying after a few seconds solves the issue. 
    • The display software menu does not always appear when remote accessing a WATCHPAX 60 that is only running SDI outputs. To resolve this, close down and reactivate remote access. 
    • There is up to one frame latency between SDI and DisplayPort outputs, with SDI outputs being behind. Latency is dependent on the show refresh rate and whether external synchronization is used or not. 
    • Setting a fixed IP through the WATCHOUT startup script can cause NDI streams to stop working on display computers. 
    • Image sequence performance may be considerably better on the main timeline than on auxiliary timelines (tasks). 
    • There may be additional latency when running audio (embedded or separated) in auxiliary timelines (tasks) compared to the main timeline.
    • Audio may have up to +100ms latency compared to video. 
    • The display software may fail to go into fullscreen mode after having been in window mode. Relaunching the software solves the issue. 
    • Audio may start playing slightly before the video in RTSP streams. 
    • Audio streams in NewTek NDI are not supported. 
    • Seeking in hardware-accelerated videos might display the incorrect frame in a paused state. H.264/AVC is limited to level 5.2. Videos encoded using a higher level will not be rendered. 
    • Seeking can produce image artifacts for hardware-accelerated H.264 video.
    • Hardware-accelerated video may be rendered one frame late. 
    • Hardware-accelerated video decoding is disabled for looping media.
    • Looping video with embedded audio might drift out of sync, if the audio stream is longer than the video (our recommendation is to use audio on a separate layer). 
    • If the network connection is lost between the production and display computers during an active show, the display software may unload the show and display the WATCHOUT logo screen when connection is regained.

    Dataton WATCHOUT® version 6.4.1

    Released July 16, 2019

    This release contains a number of fixes. 

    • Triggering a task in the display software, by setting an input variable, now works correctly.
    • The remote upgrade now works on Dataton media servers that have a fixed IP address set in the startup script.
    • Sending a "setInput" command to the display software, while it has no show running, will no longer cause a crash.
    • Fixed bugs related to multi-editing of displays.
    • Fixed bugs in the text editing dialog.
    • Some changes could be made in the Task Window, without the user being prompted to save the show afterwards. This has been resolved.
    • Fixed several bugs concerning playback of presplit images, which could result in a crash in the display software.
    • Resolved an issue where the timecode format wasn’t changed to the selected value.

    Dataton WATCHOUT® version 6.4

    Released May 7, 2019

    This version contains some new features, such as MPCDI file import and task folders, and fixes some issues.

    MPCDI file import

    You can now import display and projector calibration data from MPCDI (Multiple Projection Common Data Interchange) files. Please consult the user’s guide for more information.

    Task folders

    Auxiliary timelines can now be grouped and organized into folders in the task window. The order of timelines, folders, and timelines in folders, all affect the stacking order when rendered.

    Dragging and dropping tasks to change their order, and place them in folders, has been reworked to be more intuitive.

    Custom cue colors

    You can now set custom colors on cues, either on different types of cues through the Preferences dialog, or on individual cues in their corresponding dialog.

    Other new features

    • Manual pre-roll can now be applied on all kinds of media cues, not just video and audio.
    • You can open a capture card control panel on Dataton media servers, where applicable.
    • The task window can now be locked, to prevent any unwanted changes in stacking order, trigger conditions etc.


    • Cues are always rendered and pre-rolled, regardless of opacity, resulting in smoother playback in cues that are faded in.
    • HAP video can utilize more than 16 logical CPU cores if encoded with more than 16 chunks. This can increase HAP video performance on high-end media servers.
    • Improved overall performance on Windows 10 media servers to resolve some instances of choppy playback.
    • The process of entering or exiting fullscreen mode has been improved.
    • Enhanced NDI performance and stability (update to NDI 3.8)


    • An issue with preloading from version 6.3 has been fixed. This could cause glitches and/or poor performance of any media playback, when jumping on the timeline or using play/pause cues.
    • The production software will no longer hang if you delete a virtual display device while its corresponding media is being used in a media cue.
    • Replacing any media cue by a DMX media no longer causes the production software to crash.
    • The display software could turn black when connecting/disconnecting a display, if there was no show running. This has been fixed.
    • In Windows 10, the show’s refresh rate was not set correctly on certain displays/projectors. This has been resolved.
    • When calibrating a 3D projector while there were multiple 3D objects on different stage tiers, WATCHOUT placed the calibration points on all those objects, not just those on the same tier as the projector. This has been fixed.
    • Timecode now works with non 44.1 kHz devices.

    See notes on version 6.3 for known issues

    Dataton WATCHOUT® version 6.3.1 

    Released November 16, 2018.

    This update contains some tweaks and fixes.

    • Hardware acceleration of H.264 video is disabled for WATCHMAX 2 models WX7100 and WX9100 due to incorrect handling in MainConcept codec which may cause frame corruptions.

    This version introduces new features, including real-time motion tracking, as well as improvements and fixes. 

    Live motion tracking 

    Live motion tracking using the RTTrPM protocol is a new type of input. This multi-variable input enables media cues to mimic the position and rotation of real-world objects. It may also be used in expressions and for conditional show programming providing great flexibility. 

     More new features 

    • It’s now possible to select which MIDI device to use for input. Choose from among those connected to the system. 
    • You can now select which audio device you want to use for timecode input, including ASIO or WASAPI audio devices. 
    • It’s possible to download log and dump files from media servers, through the Stage menu. 
    • A menu item has been added to open the GPU control panel on selected Dataton media servers (requires a disk image update). 
    • You can now lock the width/distance ratio of projectors when calibrating. 
    • A compatibility mode hint has been added to address problems with dropped frames on some capture devices. This setting is available through a checkbox in the live video dialog. 
    • Basic support for audio in RTSP streams has been added.
    • Support for WATCHMAX 2 (WX7100 & WX9100) has been added. 


    • You can now open a configuration dialog for audio devices on non-proprietary media servers. This was previously only possible in the production software. Note: This does not apply to Dataton media servers which are pre-configured with optimal settings. 
    • Reliability and performance have been improved for the dynamic image server. 
    • Geometry correction now produces a sharper and more precise result. 
    • We’ve improved cluster synchronization on highly loaded networks. 
    • Reliability and performance have been improved for NDI media. 
    • Incremental improvements in audio playback. 


    • In recent Windows 10 editions, the display software sometimes failed to start if there were many high-resolution displays connected to the same computer. This is now resolved. 
    • Preloading media cues that are shorter than 3 seconds now works properly. 
    • Going online to a single media server with "Use as Synchronization Chain Master" checked will no longer cause a crash. 
    • The Color tween dialog now works as intended. 
    • In some rare cases, control cues could be skipped. This has now been fixed. 

    Known issues and limitations 

    • Audio may start playing slightly before the video in RTSP streams. 
    • Looping video with embedded audio might drift out of sync, if the audio stream is longer than the video (our recommendation is to use audio on a separate layer). 
    • NewTek NDI HX is currently very sensitive to the network configuration and may only work on a few media servers at a time. This is a NewTek issue and the best workaround is to convert NDI HX streams to regular NDI streams. 
    • H.264/AVC is limited to level 5.2. Videos encoded using a higher level will not be rendered. 
    • Seeking in hardware-accelerated videos may display the incorrect frame in a paused state. 
    • Audio streams in NewTek NDI are not supported. 
    • When remotely upgrading a WATCHPAX to 6.2.2 or 6.3 from an older version, the WATCHPAX is rebooted twice to make sure all components are installed. As a result, the production software needs to be taken online manually, after the update is finished. 
    • When upgrading the software remotely, WATCHOUT must have administrative rights for the media server (non WATCHPAX). Otherwise, essential components which are required by WATCHOUT may not be installed.

    Known issues and limitations

    • NDI HX in its current state is very sensitive to the network configuration, and may only work on one media server at a time. This is a Newtek issue and the best workaround is to convert NDI HX streams to regular NDI streams.
    • H.264/AVC is limited to level 5.2. Videos encoded using a higher level will not be rendered.
    • ASIO is not supported for LTC input.
    • Seeking in hardware-accelerated videos might display the incorrect frame in a paused state.
    • Audio stream in NDI is not supported.
    • In Windows 10 Nvidia graphics cards would produce flickering image in a multi display setup. This is solved in Nvidia Quadro drivers 385.77 and Nvidia Geforce drivers 388.00, or later.
    • WATCHOUT must have administrative rights for the media server (non WATCHPAX) when upgrading the software remotely. Otherwise, important components on which WATCHOUT depends may not be installed.
    • When remotely upgrading a WATCHPAX to 6.2 from an older version, the WATCHPAX is rebooted a couple of times, to make sure all components are installed. This results in the production software needing to manually go online again, after the update is finished.

    Dataton WATCHOUT® version 6.1

    Released March 31, 2016.

    This version contains new features, as well as optimizations and performance enhancements.

    New features

    Popup Menu

    A right-click contextual menu to improve user workflow, and in some places add new functionality. With it you can:

    • Move displays between different tiers.
    • Duplicate composition medias.
    • Reach different functionality more easily such as tweening of cues.

    Stage List

    A stage list in the Stage window, showing a hierarchical list view of all displays on the Stage, and which stage tier they are on. It can be activated from the Stage menu. With it you can:

    • Drag and drop displays easily between different tiers.
    • Go to selected display by using a command in the contextual menu.

    Auto Save

    Ability to automatically save your work in progress with a certain time interval. This feature can be turned on and off in the File menu or in the Preferences dialog, where you can also set the time interval.

    Auto Refresh

    Ability to automatically refresh media files that have changed. This feature can be turned on and off in the Media menu, or in the Preferences dialog.


    • Virtual Displays now support separate Resolution and Stage Dimensions. This is useful when dealing with LED wall modules of varying densities.
    • 3D object rendering is optimized on sub-mesh level. This makes rendering of large meshes, using multiple high-resolution videos or virtual displays, more efficient, allowing each projector to render only the sub-meshes that it can "see".
    • Presplit videos can be assigned as 3D model texture, showing one video for each display/projector.
    • Virtual Displays performance in the production software is improved.
    • Geometry correction points can be adjusted using arrow keys.
    • Projector calibration can be switched using the Tab key.
    • A preview movie can now be attached to Video Proxy even in non-presplit cases.
    • Improved License Manager window lets you scan licenses on remote display computers even when you are not currently online.
    • Displays connected to the same display computer can now have different resolutions.

    Bug Fixes

    • Some dialogs could not be opened if you had a different language setting than English.

    • LXO (Modo)

    Dataton WATCHOUT® version 6

    Modernized UI

    All new dark theme with clearly color-marked features provides both a modern look and reduces eye-strain when working in often darkened environments.

    Live Edit

    Streamlined show editingSay bye-bye to the Update command! See all changes to your show live as you make them.

    Optimized, manual modeFor cases when live update isn't desired, the old manual mode can still be used. This mode is optimized by minimizing the set of files copied to each display computer.

    Video Playback

    HAP, HAP Alpha, HAP Q high performance codecs

    Apple ProRes native codec

    V210 uncompressed video

    Image Sequences

    Play TIFF image sequences directly from disk for fully uncompressed video. Requires fast disks/SSD/RAID for best performance.

    Virtual Displays

    Create any shape of LED display, using non-standard resolutions and formats

    Map each virtual display onto an area of a real display output from a display computer, for later mapping onto the LED display modules by the LED wall processor

    Use as textures for 3D mappingCreate composite images using the familiar rendering and compositing capabilities of WATCHOUT and map the result onto 3D geometry

    Provides composition-like objects clipped by their bounds

    3D Models

    Directly import variety of 3D file formats (e.g., OBJ, 3DS, Collada)

    3D models can be used for image mapping or as "stage props" to improve pre-visualization of entire sets. Just drag the 3D model right into WATCHOUT, like other kind of media file.

    Multiple textured areas

    Each 3D model can have multiple independent areas, which can then be mapped and textured using any WATCHOUT image media, video or using the new Virtual Displays. Simply drag the image media onto the desired texture area inside the 3D model.

    3D Projector

    An entirely new way of displaying images. While a traditional WATCHOUT Display manages an essentially flat image area, a Projector allows images to be mapped onto arbitrarily complex 3D geometry.

    Position Projector in 3D space

    Aim Projector at a target in 3D space

    Rotate projector for optimal image coverage

    Accurately Models Focal Length, Lens Shift and other parameters

    Marker-based, Semi-Automatic Calibration

    A semi-automatic method for aligning the projector in 3D space. Simply line up a few well defined corners or other features in the projected image with their physical counterparts on the geometry being mapped onto. WATCHOUT does all the hard work of matching the actual position, target, rotation and focal length of the projector.


    Use imported models to build "virtual sets"

    Combine static assets, with screens and mapped objects

    View from multiple angles using multiple "camera" windows


    Create your own mask shapesUse simple editing tools directly in WATCHOUT to create masks, while seeing the result projected live as you edit the masks.

    Mask out individual objects on a per-projector basisBlock out doors, windows or other parts of objects you're projecting onto, independently of any content.

    Custom designed, per-edge, edge blendsEach mask has individually editable soft edges with variable width and gradient. All live as you edit them.

    Dynamic Image Server

    Better performancePerformance is improved greatly by optimizing the data sent across the network, thereby significantly reducing the transfer time for large images.

    Render HTML5 contentSimply point the Image Server at a URL to render the latest weather map or similar dynamic data. Content can be accessed either remotely over the Internet or stored locally on the Dynamic Image Server itself.

    Multi-channel audio

    Route channels in multi-channel audio files to their desired outputs

    Control the volume of each sound channel individually

    Supports most multi-channel sound cards or external audio boxes


    Create simple rectangular shapes right inside WATCHOUT

    Apply a feathered edge for use as drop shadows and masks

    Feathered Edge

    Apply an adjustable feathered edge and/or rounded corners to video or images.

    Video playback speed

    Adjust the playback rate of video, allowing you to match the duration of a clip to some other content, or just as an effect. This works hand-in-hand with the built-in frame blending and precise video synchronization of WATCHOUT.

    Insert/Delete Time

    New command for opening up some new space along a timeline, optionally extending cues and adjusting tween point positions.

    Show Export for WATCHNET

    Export your entire show to a single WATCHOUT Bundle (WOB) file, for subsequent deployment through WATCHNET.

    Faster show updates

    Export a Bundle Update file, containing only the changes, for faster distribution of updates of existing shows through WATCHNET.

    Multiple Display/Projector Windows

    Simplifies geometry correction across displays

    Keep multiple Display windows open on screen for tweaking the geometry correction across blends.


    Certain installation scenarios require the use of fixed IP addresses rather than the normal dynamic addressing used by WATCHPAX. You can now specify a fixed IP address along with router and DNS addresses, if desired.

    Please refer to the WATCHOUT User's Guide for full details.
