4.2.1 Release Notes

Hippotizer is continuously being developed and improved; please read these notes carefully to
understand the changes and limitations with each version.

Version 4.2.1:
4.2.1 adds many fixes and improvements to 4.2. Green Hippo strongly recommends using 4.2.1 in place
of 4.2 wherever possible.
Note: 4.2.1 No longer supports the playback of Mpeg 2 Clips. Media encoded to Mpeg 2 will appear greyed
out in the media library and will not play if selected. Please re-encode all media to FlexRes .

• *Content encoded from ProRes 444 may show a slight colour shift compared to the original
due to an issue in the 3rd party media encoder. The ProRes 444 family also has limited
support in Windows so it is best to test the specific codec and resolution when establishing
a content workflow.
• **As of Version 4.2, HAP content can be ingested without transcode.
• ***Audio files with more than two channels can be encoded if they are part of an image
sequence (in the same folder as the image sequence with the same name, or are separated
from the video file before encode. Place the audio file in the same path as the media to be
encoded and ensure they have the same name.
Martin P3-PC compatibility
Hippotizer can send video directly to the Martin P3-PC application running on the same machine, this
requires a P3 Dongle. The version of P3-PC and Hippotizer is important to ensure correct operation:
Hippotizer Version P3-PC Version
4.1 4.2
4.2 4.2.2
4.2.1 4.2.2

Current CITP Support
CITP (Capture Interface Transport Protocol) is an open network protocol to allow visualisation software
and lighting desks to exchange thumbnails and streaming previews from media servers. Green Hippo
works to ensure CITP is working correctly with as many 3rd party applications as possible. Here is a list
of currently tested systems against this version.

• If using Quad SDI capture cards we recommend Datapath Driver version 7.16

Current Display Drivers
Hippotizer Media servers use one of several type of graphics card, which are tested with current and

• Boreal DVI-DL
• Boreal SDI
• Boreal DVI Genlock
• Karst DVI Genlock
• Karst SDI
• Amba with Serial number 240037 or greater
Note: Newer Firepro drivers have shown less playback performance than the recommended 15.301
Current Recommended Standard Driver: 15.7.1
Systems affected:
• Boreal DVI Single Link
• Karst DVI Single Link
• Amba with Serial number between 240001 – 240036
Installation Notes
• 4.2.1 can be run as an upgrade installation if 4.2 was previously installed.
• 4.2.1 must be run as a clean installation if 4.1 was previously installed.

• If 4.1 is previously installed, un-install it before installing 4.2.1.
From version 4.2 On wards the Hippotizer data is stored in new locations to comply with
Microsoft Windows security guidelines.
• The binaries (executable files) are stored in: C:\Program Files\GreenHippo\HippotizerV4
• The settings are stored in: C:\Users\\AppData\Local\GreenHippo\4_2
• The Media folder by default on Portamus and Play is: C:\ProgramData\GreenHippo\MediaV4
Major Changes In behaviour
• MPeg 2 Playback capability has been removed.
• An Mpeg Export facility has been added to media manager, and a conversion tool added to Hippo
• The layer icons icons in the Windows system tray have been changed; an Icon now loads per mix,
with a number indicating the number of loaded layers in that mix.
• Timecode display on layer and in the media player has been set to default to HH:MM:SS:Frames
as opposed to milliseconds. Displays in time are in real-time and therefore will differ from
Timecode time for specific timecode formats such as 29.97 Non Drop Frame timecode.
• The image sequence detection in Watchfolders has been changed. Any images with the same
name and ending in a number will be treated as a sequence. Use the convention of file name,
followed by map slot (if applicable) and then frame number: FileName[1,2]_0001
• The ability to export the media manager component has been removed to avoid potential media
corruption and data loss. To back up your media, copy the media folder.

exchange after a failure often succeeds.

present. Simply run auto-patch after all layers are running to create a correct patch.
