Some machines are suffering from an issue that when the EDID Force Emulate checkbox has been ticked, it cannot be undone. This leads to the inability to change or remove EDID’s.
To note, this checkbox is generally best avoided.
If you are suffering from this issue, please follow these steps to remedy.
1. Open Windows Run and type ‘regedit’
2. In the program ctrl+f and search for ‘EdidPersistenceIsOn’
3. The value this entry holds should be ‘00’ if anything else right click and select modify and change the value to 00.
4. Restart the machine.
5. The issue should now be resolved.
We have yet to find a pattern for this bug. If you do suffer from it, please contact us at firstname.lastname@example.org with as much information as possible so we can try to find the root cause of this issue.
How to set Hippotizer V4 outputs to 50Hz What is Hz:
“Hz” is the abbreviation for Hertz, which refers to the refresh rate of a video signal. In other words: the number of times per second that a new video frame is generated by Hippotizer.
Another term thrown around a lot with the refresh rate is “p” and “I”. These are short for “Progressive” and “Interlaced” respectively. A progressive signal (so 1920 x 1080p 50Hz or simply 1080p 50 for example), is sending an entire video frame 50 times a second. While an interlaced signal (1080i 50) is sending alternate horizontal lines with each refresh. This means that frame 1 in an interlaced signal is horizontal lines 1,3,5 to 1079 and frame 2 is 2,4,6 to 1080. This than alternates so that display can render an entire frame every two interlaced frames it receives.
Interlaced signals are common in broadcast as it reduces the bandwidth required to send a TV signal.
Why use 50Hz:
Many broadcast and TV event studios, in Europe specifically, require that media servers output at 50 Hz. The Broadcast standard PAL uses a 50 Hz interlaced signal, which means that a 50 Hz signal from Hippotizer is easier to use for these studios. Outside of Europe, 60Hz is more common. (This corresponds to NTSC and PAL-M broadcast standards).
Step 1: EDID Emulation
• Right click the desktop and open the Catalyst control centre.
• Select the AMD FirePro drop-down menu and select the EDID Emulation option.
• Within this menu, select the AMD FirePro w9100 10 option and then the Display Connection option.
• Select all the connections that the emulation will be added to.
• Select from either the Display option drop-down menu or by adding a previously saved file.
• Click Apply
Optional Step (Only for Machines with Intel boards)
• Open Intel Graphic Properties
• Click on Display, then from the Display drop-down menu select Custom Resolutions
• A Warning will appear, acknowledge it.
• Set the custom parameters e.g. 1920, 1080 & 50
• Back on general display, change the refresh rate to 50Hz
• Click apply
Step 2: Setting the Display
• In Catalyst Control Centre, open the Desktop Management section
• In Desktop Properties, the displayed mode should now be at 50Hz. If not select from the drop-down menu and click apply. Repeat for all.
Step 3: Start Up
• Now start Hippotizer.
• Within Zookeeper, go to outputs and select the viewport. The Refresh rate should be 50. If not click configure.
How To: CITP Connection and Thumbnail sharing between GrandMA2 and Hippotizer V4
What is CITP:
CITP (Controller Interface Transport Protocol) is a protocol used to originally communicate between lighting desks and visualisers. The protocol has since been expanded to now include media servers. The purposes of this communication include: Browsing media and thumbnails, SDMX and streaming media.
GrandMA2 v18.104.22.168 v22.214.171.124. v126.96.36.199
Ensure that the IP address for both are within the same range for both the Hippotizer as well as the GrandMA2 desk. (A recommended set up for a wired link is 188.8.131.52 255.0.0.0 & 184.108.40.206 255.0.0.0)
Ensure that Windows Firewall is either set up to allow for the traffic between these two points or is disabled.
Inside Zookeeper on the Hippotizer, enter the configuration page and on the Host Info and Components page, click add on the bottom left.
Select the CITP Component and click add.
In a new or existing layout, open the HippoNet menu in the bottom left and drag out the CITP component. Ensure the component is active and is using the correct network Interface and Multicast Address. (The original Multicast address was 220.127.116.11, but a newer standard of 18.104.22.168 was introduced. However, not all systems support this yet.)
In the GrandMA2 Setup menu, select Patch and Fixture Schedule.
Give the Layer you wish to use a name.
In the Fixture type select from Library.
Search “Green Hippo” in the manufacturer field.
Select the “v4.2 – Layer” mode and import it
Fill out the variables as needed and select Apply.
Back in the GrandMA2 Setup menu, select the CITP Network Configuration option
Ensure CITP is enabled (Green Border around the button)
Click Add Present. This will automatically add any Media Servers with enabled CITP on the network.
On the Fixture Layer field, right click and select the correct option.
Now Click Update Thumbnails (A blue loading bar should go across the CITP Command field).
Select Extern 1.
Right click on the pin board and select the Other tab.
Select the Smart option.
Select Gobo and the thumbnails will appear in the Smart window.
The addressing scheme used is not valid e.g. 192.168.1.1 connecting to 22.214.171.124
The firewall on either side is preventing for full communication (this can potentially still allow them two sides to see each other, but will stop the sharing of thumbnails and content)
