Hi Peter,
We understand your frustration and pain of having to terminate all your cables. When designing the spacing we used standard BNC connectors. Unfortunately this did not include using push/pull style like you use. We also wanted to provide customers with the ease of using Trompeter or similar insertion tools which I believe are not suitable for this style of connector.
Thanks for your support of Blackmagic products and for the suggestion of including this information in our specifications. We are discussing this further as a result.Regards,

Hi Robbie,
The parade view will show RGB gamut errors whilst the B/W view (YUV colour space) will show luminance gamut errors. These are quite separate and on everyday footage the errors may be different but on extreme images may show similar areas in error.
Like RGB gamut errors, luminance error thresholds can be set up in the profile.I hope this helps.

Hi Rob,
We can confirm that what you are experiencing only applies to early Workgroup Videohubs but not all when updated with new firmware. Unfortunately we will not be doing any further development on this product. You will need to use the original firmware.

Hi Rob,
We have found that V1.0 was released in October 2004. We have tried installing this into our Videohub but have discovered that this is not possible due to the current operating system. What are you running?

Hi Rob,
I am sorry to hear about your issue and frustrations.
I will do some further investigation and get back to you later next week.
Our testing of our latest software releases has shown no problems with Workgroup Videohub apart from the keying as Sam mentioned.
Have a happy and safe New Year.

Hi Alexandr,
Unfortunately it is not possible to control two routers with the one panel.

Hi Alexandr,
Firstly, we have two Blackmagic Dealers in Moscow. Details can be found at https://blackmagic-design.com/au/resellers/resellers.asp
To answer your question, you can control Compact Videohub by many Smart Control panels. Four will be very easy. Connect the panels and router to you IP Switch/Router. These will be assigned an IP address and each panel is then configured via the USB utility (supplied with the equipment) to control the Compact Videohub.
I hope this helps.

Hi Scott,
Our QA guys have just tested our HDMI to SDI mini converter connected to Ultrascope. HD and SD NTSC bars were very accurate and program material also looked fine.

Hi Scott,
Unfortunately HDMI cannot be connected directly to Ultrascope. Using a converter is the only way.

Hi Robert,
Our engineers have reproduced the same source data and investigated the outputs, conversions, etc. First of all, the display on the Tektronix 7120 scope we tried looks just the same. As this is considered to be the benchmark, we have concluded that a fix is not necessary.
The image you have generated in After Effects in RGB,has extreme transitions in the different colour channels ie. going from red (1,0,0) to white (1,1,1). You can get away with this in computer graphics, but not video/broadcast, as this requires infinite bandwidth for instantaneous transition from 0 to 1. Since broadcast is bandwidth-limited, it is necessary to filter the output, which AfterEffects presumably does. Also, it is converting from full-scale RGB to YCbCr on output.
In all this conversion and filtering a certain amount of ringing artefacts gets introduced at the hard edges, so the pure switch from a red column to a white column ends up having more of a ramp of a few columns between them on output. When this signal is sent to UltraScope, it already has artefacts in the YCbCr. When this gets converted back again to RGB for the parade display, the ringing becomes even more evident.
Thanks for your support of UltraScope.
