Bug Fixes / Other Workarounds
Fixed a bug recording from the ARRI ALEXA, in which the Gemini Recorder could get out of sync
with respect to the Vari-Frame setting on the camera. The Gemini Recorder should now always
correctly detect and follow the camera's Vari-Frame setting.
Fixed compatibility with Mac OS Mountain Lion. SSD mounting and interaction with Finder was
very sluggish, the interaction is now back to normal.
Please note: It is imperative that only the Convergent Design Universal Transfer Station (in
conjunction with a GoFlex or other compatible USB/Firewire/Thunderbolt adapter) is to be
used for offloading data from an SSD to any computer. Do not use the original eSATA Transfer
Station with the Convergent Design SSD's, as the original transfer stations are susceptible to
damaging the SSD's under certain conditions.
Also, be certain to use the Volume Safe Eject within Mac (Finder) and Windows (Safely Remove
Hardware icon in bottom right of screen, if available) before pulling an SSD from the Transfer
Station, after data has been offloaded. Pulling an SSD without using Volume Safe Eject on the
Mac can damage the SSD!
With a recent firmware upgrade, the Sony F3 camera now has 2 options for it's “SDI Rec
Control”, which activates Camera Trigger to the Gemini Recorder.
Please note that only the “HD SDI Remote I/F” option works properly with the Gemini. Do not
use the “Synchro Rec” option!
For using Vari-Frame with the ARRI ALEXA: please note the following:
o
If “Sensor Rate” on the ALEXA is set to 30 or less, set the “Record Out” to 30 or less as
well’
o
Do not set the “Sensor Rate” to less than 1 on the ALEXA
o
Do not set the “Sensor Rate” on the ALEXA to 23.98 and the “Record Out” to 24
o
Do not set the “Sensor Rate” on the ALEXA to 29.97 and the “Record Out” to 30
o
“Sensor Rate” must be less than or equal to “Record Out” rate
For this release, to boot into ARRIRAW or 3D DPX (via the Setup->Mode menu), a memory
swap may be required, which will take about 1 minute. A dialog prompt will guide the user
through this process.
Known Issues
3D DPX Recording: occasional incorrect values in timecode.
Canon Raw Recording: occasional incorrect values in timecode.
Canon Raw Recording: occasionally the last frame or 2 of a clip are unusable.
If the Gemini Recorder is in Canon Raw mode, and a standard 1080p video input is attached to
the Recorder (instead of a Canon Raw input) , an inappropriate message such as “Set Raw” will
sometimes appear.
In fact, in this situation the unit should be set to DPX (under Setup->Mode in the Menu) to
record DPX from a standard 1080p input.
