Hey there.


We have recently purchased the ATI Radeon HD6990 with 4x Mini Display Ports and 1x Dual Link DVI Output. We have also purchased the Black Magic Decklink SDI Capture Card for an upcoming gig. As we have just got it all working together we thought we'd put it to the test, only to discover, that the input from the capture card doesn't work over the blended areas, it simply appears blank. Please let us know if there is something we are doing incorrectly so that we can solve this issue. Our proof of this issue is that after going to File/Preferences/Edge Blend and taking the blend out all together, immediately the full capture spans across all the displays. This is something we are hoping to rectify else we will need to pull in the likes of an encore or similar and budget of course doesn't allow. So if you have any ideas, please let us know by responding in this post.


Many thanks.

I recommend that you update to WATCHOUT 5.1, released 17 October.


From the Relase Notes:



Dataton WATCHOUT version 5.1

This version of Dataton WATCHOUT™ provides a few minor enhancements and a couple of bug fixes.


  • The Move command includes the Z axis.
  • The Consolidate command allows you to include all media files, if desired, and not just those actively used in the show.
  • A Control cue can explicitly target the Main Timeline.
  • Control of Inputs (DMX, MIDI and Generic) is now managed by the display software when production computer isn't online.
  • MIDI Show Control is now handled by the display software when production computer isn't online.
  • Large images or images extending outside the display don't appear if the display is rotated.
  • When using multiple outputs from one display computer, video file playback on other displays than the first sometimes doesn't start smoothly.
  • On the Production computer the sound output stops playing if the icon is not visible in the stage window.
  • Export of a timeline to a movie file may not complete under some circumstances.
  • Stage Tiers not working correctly.
  • Didn't accept expressions such as: (in3 * 500) - 250
  • Running a single display computer without a network connected (e.g., from serial control or a command file) failed opening the show.
  • Creating audio waveforms from long audio files or MP3 files could crash.
  • Audio waveform may not be displayed properly immediately after opening a show.
  • Audio waveform display failed for WAVE files with floating point data.
  • Switching shows without re-starting the production software could cause tween tracks controlled by inputs to behave erratic, flipping back and forth.
  • The path to any Preview movie wasn't adjusted properly when transferring the media to another show by copy/paste of cues.
  • Playback of multi-channel Wave files wasn't always accurately synchronized.
  • Watchdog could time out while caching numerous files during an Online or Update operation, thus making the whole operation fail.


Version 5.1 comes with an updated license key driver. Therefore, you must install this version manually on each computer, as WATCHOUT's automatic remote update feature can't update the license key driver.

Hi Transco,


Blackmagic devices are VERY particular with their settings.


Ensure everything between input and output and in Watchout. (eg 720p refresh rate 60Hz)

I had the same problem when first using BM capture cards.
