Inputs/Outputs
• First activation of Return Input may show distorted image
After booting or setup of the camera, at the first switch from the live camera image to the return input, the SDI output
may show a distorted frame. With any following return activation, the switch will be clean.
• Wrong False Color mode at SDI 2
When setting the SDI 1 output to "Clean" and SDI 2 to "Processed", the False Color function will always show the
"Monitor Based" mode on the SDI output, also when it is set to "Log C-Based" mode. When SDI 1 is set to "Processed"
and SDI set to "Clean", the False Color function works as expected.
• SDI interlaced field order reversed with V/H flip
When activating a V or V+H flip, the field order of the interlaced format at the SDI outputs will be reversed.
• Potentially distorted lines when SDI frame rate is larger than sensor frame rate
When setting the SDI output frame rate to 59,94 or 60 fps, while the recording frame rate is 50 fps (or smaller), there
might be line artefacts in the SDI image.
• Entering/exiting playback mode cause momentary signal loss
When entering or exiting the playback mode, the SDI outputs will show a momentary loss of the SDI signal if the
recording frame rate is double of the project frame rate, or if the recording format is interlaced.
• SDI status overlay may show wrong processing icon
Even when the processing mode is set to A709, on the particular SDI output a Log C icon may be shown.
• SDI outputs when using timecode sync
When using a timecode signal as sync source, the SDI outputs may not be precisely in sync to the sync source. For
precise SDI out sync to sync source please use a tri-level genlock signal.
• Monitoring in 3.2K with 1.3x anamorphic desqueeze
EVF/Monitor and SDI outputs may show scaling artifacts in 3.2K recording mode with 1.3x anamorphic desqueeze
enabled. The artifacts are limited to the monitoring outputs, they do not affect the recordings.
• 1.3x anamorphic desqueeze is not available for UHD SDI output
1.3x anamorphic desqueeze is not applied to UHD SDI output 422 6G, DL 422 6G and 422 3G DL.
• 1.3x anamorphic desqueeze is not available for EVF zoom
1.3x anamorphic desqueeze is not applied to the EVF zoom image.
• Momentary image loss on SDI outputs when connecting a sync source
The SDI outputs re-synchronize when connecting a genlock or timecode source. While re-synchronizing a short image
loss may occur.
• Temporary image loss on SDI outputs when configuring 6G
When changing the SDI output to 6G, or when changing the SDI output from 6G to another format, both SDI outputs
may exhibit a short image loss.
Media
• Protection against cross platform CFast 2.0 formatting issues
Only CFast 2.0 cards that have been erased on ALEXA Mini or AMIRA running SUP 4.0 (or higher) can be used for
recording. This is for protection against issues caused by different CFast 2.0 formatting schemes used by other
cameras manufacturers.
Metadata
• Tilt and roll metadata not accurate
Tilt and roll values in metadata may not be accurate enough to be used for VFX applications.
