■ One example is that when outputting 4K, HFR, YCbCr 4:2:2 10-bit from the framebuffer, if the HDMI
transmitter is version 1.4b then the video is adjusted to 4:2:0 8-bit (e.g. KONA 4, KONA IP).
● Added 2SI alignment pattern in AJA Control Panel, consisting of 1-pixel diagonal crosshairs plus a 3-pixel rectangle.
○ Whenever there is a misalignment, the diagonal crosshairs will be wrong, not a continuous line.
○ If it is a top-bottom misalignment, the top and bottom of the square line will be broken, with white between
time. This is easily simulated by clicking the "Quad Swap" buttons in the control panel "Video Setup" tab.
○ If it is a left-right misalignment, the left and right lines of the square will be fuzzy, or broken.
● AJA Control Panel Restart Services is new functionality that allows for restarting the AJA services if necessary. This
can help if various applications begin contesting for access to the Video I/O device. In this case using the "Restart
Service" command will bring AJA Control Panel back to its startup state, and an application can freshly acquire
control of the AJA Video I/O device.

Known Issues, Limitations and Additional Details
__________________________________________________________________________________________________________
General
● “System Sleep” or “Hibernation” should not be used with KONA and Io devices. All sleep and power efficiency
modes should be disabled in the operating system settings.
Important macOS Big Sur installation information
● Starting with macOS 11.2 (Catalina), new installations of AJA’s Desktop Software must be v16.0 or later.
● In some cases, you may be asked to allow driver in security settings - and this may happen more than one.
● AJA shortcuts are automatically deleted from Dock upon uninstall starting in macOS 11.2.
● Follow the images below to navigate the security and installation dialogs in the successful order.
_____________________________________________________________________________________________________
AJA Desktop Software – macOS v16.1 drivers and software for KONA, Io and T-TAP Pro - Release Notes | www.aja.com 21
● After restarting, if the system fails to load the AJA driver:
○ Open the Terminal application.
○ Type in "sudo touch /Library/Extensions" into the Terminal window … then press Enter or Return.
○ When prompted, enter the password for the administrator account.
Important macOS Catalina installation information
● Starting with macOS 10.15 (Catalina), new installations of AJA’s Desktop Software must be v15.5 or later.
Important macOS Mojave installation information
● Use AJA Desktop Software v15.2 or later.
● Starting with macOS 10.14.5 (Mojave), new installations of AJA’s unified software package must be v15.2, or later.
Apple notarization requirements for macOS 10.14.5 onwards mean that previous versions of the AJA Desktop
Software package will not install / work correctly with macOS 10.14.5 onwards (unless “grandfathered” in via being
installed previous to the macOS upgrade to 10.14.5).
● With the introduction of macOS Mojave (v10.14), Apple now requests that third party kernel extensions be
“notarized” by Apple. AJA’s device driver kernel extension has been notarized starting with AJA Software version
15.2. Apple has indicated that for security purposes, future macOS versions may prevent the loading of unnotarized
device drivers, in which case, AJA software prior to v15.2 will result in AJA devices failing to operate (Unsupported
AJA Device).
_____________________________________________________________________________________________________
AJA Desktop Software – macOS v16.1 drivers and software for KONA, Io and T-TAP Pro - Release Notes | www.aja.com 28
Important macOS High Sierra installation information
● Use AJA Desktop Software v15.2 or later.
● With the introduction of macOS High Sierra (v10.13), Apple now requires that third party application developers be
identified during kernel extension installations. Failure to do so will make AJA devices fail to operate (Unsupported
AJA Device).
● Depending on your macOS version and AJA Desktop Software installation history, the following installation
outcomes are possible:
○ macOS Sierra and Earlier Supported Versions
■ No problems exist for AJA software installation or updates with these earlier versions of macOS.
○ Earlier macOS to High Sierra Update
■ No problems should occur if the AJA Desktop Software package is already installed on macOS
Sierra (or earlier) and then update your Mac to High Sierra. The identification of AJA as a trusted
developer is “grandfathered in” to High Sierra.
○ macOS High Sierra First AJA Desktop Software Install
■ No problems should occur if your Mac is running High Sierra macOS, you install AJA Desktop
Software for the first time, and you follow the instructions shown during installation (Figure 1).
■ Do NOT click OK (Figure 1).
Figure 1 — First-time installation on macOS High Sierra
Instead click Open Security Preferences (or go to System Preferences>Security and Privacy) and then click Allow
for AJA Video Systems (Figure 2).
Figure 2 — click Allow for AJA Video Systems
NOTE: If after successful installation, you remove AJA applications from your computer using the AJA Uninstaller
developer identification is retained by macOS High Sierra. Re-installation should proceed without any problems.
_____________________________________________________________________________________________________
AJA Desktop Software – macOS v16.1 drivers and software for KONA, Io and T-TAP Pro - Release Notes | www.aja.com 29
● Recovery from Installation Approval Failure:
○ If you clicked OK during installation and skipped the developer approval step, the AJA Desktop Software
installation will complete, but macOS’ GateKeeper security will prevent AJA’s device driver from loading,
and AJA devices will not not operate (Unsupported AJA Device).
○ Apple has allowed a time window, within which you can belatedly approve a developer after installation. If
you go to System Preferences>Security and Privacy, within 30 minutes of installation, the developer
message and Allow button will be available for use. After 30 minutes, however, the message and button
are removed from the window. Recovery from this involves uninstalling all AJA files (some manually),
reinstalling the AJA Desktop Software package, and clicking on Allow for AJA Video Systems developer.
● Recovery from Installation Approval Failure (2nd Level if necessary)
1. Run the AJA Uninstaller, located in the AJA Utilities folder in the Mac Applications folder.
2. Access the Users Library, which is hidden. To access the library:
3. Go to the Finder.
- In the Finder Menu Bar and click on Go.
- Hold down the Option key. The Library folder appears as long as the Option key is held down.
- Go to Library>Preferences and delete all com.aja.*.* files. There may be one file or several files.
4. Remove AJA Control Panel from the Dock, if applicable.
5. Restart the Mac.
6. Install the AJA Desktop Software package.
7. During installation click on Open Security Preferences (or go to System Preferences,>Security and Privacy).
8. Under the General tab click on the Allow button for AJA Video Systems. The button is only available for 30
minutes.
12-bit RGB support (4K/UHD)
● Additional 12-bit RGB support has been added for KONA 5, Io 4K plus, Avid DNxIV, Io IP, Avid DNxIP enabling an
expanded range of HDR and other 4K/UHD workflow possibilities via both HDMI 2.0 and SDI. Note that 12-bit RGB
support includes frame rates up to 30p only.
● 12-bit RGB via HDMI from KONA or Io will deliver 12-bit to the downstream (sink) device provided it is capable,
otherwise the bit depth can be down-rated based on the capabilities of the monitor or other sink (communicated to
KONA via sink device’s EDID):
○ In AJA Control Panel “Auto Detect” will put out the signal that works with the receiving monitor.
○ In AJA Control Panel “Auto-Set” will use what the Frame Buffer is set to.
AV Sync
● For highest accuracy, always use the Video and Audio coming from your AJA device for monitoring. Using an AJA
device for Video monitoring, but using the host for Audio monitoring may result in AV sync or drift issues. If these
issues arise it is a function of your host system/OS, and AJA recommends monitoring Audio via AJA device.
KONA 5
● KONA 5 bitfiles.
○ There are two main KONA 5 bitfiles: “KONA 5” and “KONA 5 (8K)”.
_____________________________________________________________________________________________________
AJA Desktop Software – macOS v16.1 drivers and software for KONA, Io and T-TAP Pro - Release Notes | www.aja.com 30
● "KONA 5" bitfile supports:
○ Up to 4K I/O YCbCr & RGB (including Color Space Conversion)
○ AJA Control Panel (including AJA Audio-Mixer)
○ AJA Control Room
○ Adobe Premiere Pro
○ Apple FCP X
○ Avid Media Composer
○ Telestream WireCast
○ Video Mixer/Keyer up to HD 60p
● "KONA 5 (8K)" bitfile supports:
○ Up to 8K I/O YCbCr *or* RGB (no Color Space Conversion)
○ Full 2SI path for the 8K raster (in additional to a Square Division presentation of 4x 4K 2SI)
○ 8K to 4K subsample via HDMI 2.0 out
○ AJA Control Panel (not including AJA Audio-Mixer)
○ AJA Control Room
○ Adobe Premiere Pro
○ Video Mixer/Keyer not supported
● If loading KONA 5 (8K) bitfile, be aware of the following:
○ For 4K/UHD 12G-SDI and 6G-SDI are supported for I/O.
■ 3G-SDI or 1.5G-SDI for 2K/HD I/O is supported.
■ 3G-SDI or 1.5G-SDI for 4K/UHD is currently supported for Input only.
○ Host system performance is going to be the gating factor in what frame rate is achievable for 8K Capture or
Playback. Test Playback first, since it’s unlikely a system which cannot play 8K will be able to capture 8K.
○ When set to Square Division, I/O configurations must be manually set using the frame buffer in AJA Control
Panel (see below).
○ To set up for 8K Input with 2SI, under 8K Transport choose “Auto” or “8K-2SI”
○ To set up for 8K Input/Output with Square Division, under 8K Transport choose:
■ “4x8K” for either 8K YCbCr HFR or 8K RGB LFR over 4 connections
■ “2x8K” for 8K YCbCr LFR (6G-SDI) over 2 connections
○ AJA System Test is not presenting data in a user friendly manner for 8K/UHD2.
○ AJA Control Room, Adobe Premiere Pro and Adobe After Effects are supported for 8K/UHD2 Input and
Output. There is currently no support for Apple, or Avid applications.
○ Level-A only for 8K/4K. Level-B support is only relevant to HD signals.
○ 10-bit I/O with YCbCr,. 12-bit I/O with RGB only.
○ Apple ProRes family supported (encode and decode).
○ Audio is present and can be Captured or Output. AJA Control Panel Audio Mixer is not available.
KONA IP, Io IP and Avid DNxIP
● KONA IP, Io IP and Avid DNxIP, can be used with two different firmwares: ST 2110 firmware or ST 2022-6 firmware.
● KONA IP and Io IP, with ST 2110 firmware:
○ Is capable of supporting ST 2022-7 for Transmit- set SFP 2 to “true” (within the same channel)
○ Is not capable of ST 2022-7 for Rx
○ The maximum resolution and frame rate supported via ST 2022-7 is 2K/HD 60p.
○ There is no ST 2022-7 support when using ST 2110-23.
○ It is currently necessary to enable Closed Captioning in AJA Control Room in order to Capture Time Code.
_____________________________________________________________________________________________________
AJA Desktop Software – macOS v16.1 drivers and software for KONA, Io and T-TAP Pro - Release Notes | www.aja.com 31
○ It is recommended to disable channels not in use i.e. disable Ch 3 when Ch 4 is desired.
Io 4K Plus and Avid DNxIV
● New functionality introduced as of v15.5.3 for Io 4K Plus and Avid DNxIV provides for smoother and faster
transitioning between Capture and Playback. See below under Media Composer for more notes, and consult the
manual for full details.
● Currently, some SD sources do not work correctly when ingesting via HDMI. Please contact AJA Support to report
this issue if you run into it.
KONA LHi
● RP188 LTC playback on macOS is not currently functional. RP188 LTC capture is functional. RP188 LTC pass through
is not a feature of the card.
● When using level A 1080p50/59.94/60 YUV input to an RGB frame buffer for capture, the image is scrambled or
non-working for various NLEs. In Adobe Premiere CC, this issue causes the app to become unresponsive when
using an RGB10 frame buffer/capture codec. Note that Level B works correctly with all supported NLEs.
● KONA LHi has only one audio system and is limited to capturing or outputting one channel at a time with audio. In
applications where multiple video inputs and outputs can be used at the same time, the SDI input will have audio
and the HDMI input will not. Additionally, if both input and output are used simultaneously and independently (as
opposed to output passed through from input) only one channel will have audio.
KONA LHe Plus
● KONA LHe Plus is not compatible with 2019 Mac Pro via PCIe slots.
● KONA LHe Plus is compatible with 2019 Mac Pro via Thunderbolt (i.e. PCIe card in Thunderbolt Chassis)
KONA HDMI
● Audio channel configurations differ between Ports 1 and 2, vs. Ports 3 and 4.
○ AJA Control Panel has an audio channel swap feature to ensure compatibility.
● Some SD sources do not work correctly when using channels 1 and 2. Please use channels 3 and/or 4 for SD
ingest.
● Occasionally, HDMI sources do not work correctly. Please contact AJA Support to report this issue if you run into it.
AJA Control Panel
● AJA agent stops running following unplug of TB device. This manifests itself most clearly when running more than
one AJA device on the same host at the same time.
● Workarounds for macOS
○ Re-plug the Thunderbolt device, and the agent will restart.
○ Otherwise, on macOS "Warning Text" will show in AJA Control Panel (“restart Agent”) and the agent can be
restarted by clicking this menu item.
● Workarounds for Windows
○ After an unplug, it will be necessary to restart AJA Control Panel and AJA Control Room.
_____________________________________________________________________________________________________
AJA Desktop Software – macOS v16.1 drivers and software for KONA, Io and T-TAP Pro - Release Notes | www.aja.com 32
○ For Windows systems, an administrator could also manually stop and restart the service to get the agent
working again.
AJA Control Room
● H.264 playback in AJA Control Room is in beta for the v16.1 release. We do not recommend using this feature for
production until the functionality is completed in a forthcoming release. We do however welcome any feedback
that may result from trying this new functionality out.
● MXF OP-1A capture in AJA Control Room does not support the following formats: 720p60, 1080i30, 1080p30,
1080p60.
Adobe Applications
● The first version of Adobe Premiere Pro to natively support Mac M1 (July 2021) will not support capture. Instead, use
AJA Control Panel to capture material which can then be used for editing within Premiere Pro.
● Versions of AJA Desktop software prior to v15.5 will not show video preview during capture on Premiere 2020.
However capture of content will not be affected.
● With rasters above HD/2K, Adobe After Effects may struggle to deliver frames in real time. AJA hardware will buffer
as much as possible, but if frame rates get very slow, it will be impossible to sustain smooth real-time playback on
the reference monitor.
● Audio output from AJA devices can be compromised when sequence frame rates do not match hardware frame
rates.
○ This can occur when working in 720p formats other than 720p-50, 59.94, 60.
○ To work around this limitation, go to Premiere Pro Playback preferences, and set the AJA video device to
‘Match Control Panel’. Then set up a cross-conversion to output 1080 format. For example, if using a
720p-23.98 project, set the AJA Control Panel to cross-convert to 1080PsF-23.98, which is a valid SDI
output.
● Timecode is not stored in crash captured clips when the timecode source is RS-422. If this is required, use
embedded timecode instead of RS-422 timecode.
● Variable frame rates (VFR) with pull down added are not adjusted for timecode.
● ‘Crash Capture’ and ‘Print to Video’ will work on Varicam frame rates over HD-SDI, but ‘Insert Edit’, ‘In/Out. Capture’,
and ‘Batch Capture’ will not.
● When insert editing on Panasonic decks, destructive edits may occur too early on the tape. In order to avoid this,
be sure that menu item 202 “ID SEL” is set to “OTHER”.
● Preroll shorter than 4 seconds is not recommended for use with any deck, for capture or layback.
● Premiere Pro defaults to ‘Display First Field’ in its monitor wing menus. If interlacing issues appear on the output of
AJA hardware, try changing this setting to ‘Display Both Fields’.
● When changing from a DF tape to an NDF tape on the same deck, with the Premiere Pro capture window open, the
NDF/DF status may not be picked up correctly. If this happens, the timecode values seen in the Premiere Pro
capture window may be incorrect.
○ This Issue will NOT affect users unless they are changing between DF and NDF tapes on the same deck, in
the same Premiere Pro Capture session.
○ To Avoid This: Always give the new tape a new name in the ‘ Tape Name’ dialog that appears when
changing tapes and be sure to let the new tape spool up all the way before clicking the ‘OK’ button on the
dialog.
○ To Fix This: Close the Premiere Pro capture window and reopen it.
_____________________________________________________________________________________________________
AJA Desktop Software – macOS v16.1 drivers and software for KONA, Io and T-TAP Pro - Release Notes | www.aja.com 33
● When capturing from or exporting to a Panasonic D5 deck, the timecode source setting in the AJA Premiere Pro
Device Control plug-in must be LTC+VITC.
● MXF OP-1A capture in Adobe Premiere Pro does not support the following formats: 720p60, 1080i30, 1080p30,
1080p60.
Apple FCP
● Currently in FCP, scrubbing an audio only clip when in the "organize" workspace results in FCP and the AJA device
temporarily losing contact with each other. Switching back to a timeline should reinstate (acquire) the hardware
smoothly, however, this should not occur when the A/V Output is turned on in the Window menu.
Avid Media Composer
● Support for HDR via Media Composer arrived with AJA Desktop software v16.0. One known limitation is when
linking to HDR media, the Media Composer Source Setting Adapters may get misgenerated. Deleting them will
resolve issues viewing HDR correctly.
● New functionality introduced as of v15.5.3 for Io 4K Plus and Avid DNxIV provides for smoother and faster
transitioning between Capture and Playback. Note that there are recommended combinations of settings covering
both Capture and Playback, please consult the manual for more detail.
○ Note: If a recommended settings combination is not chosen, then lock-up operations may take several
seconds when engaging/disengaging the capture tool. This could occur for example, when External Ref is
set for Capture but not for Playback, or vice versa.
● AJA hardware does not control for, legalize or clamp video according to broadcast legal values. Use the tools in
Media Composer to achieve legal broadcast levels. Note that AJA does prevent illegal levels according to the SDI
specification, but this is not the same as the broadcast legal controls available inside Media Composer.
● For HDR, there may be some inconsistency in the state of AJA Control Panel when changing projects.
Recommended best practice is to check your HDR settings in AJA Control Panel after switching Avid projects.
● For HDR with Media Composer 2019.11 and after, with AJA KONA 5, KONA 4, KONA IP, Io 4K Plus, Avid DNxIV, Io IP
and Avid DNxIP is able to drive AJA Control Panel directly, so adjusting HDR parameters manually in AJA Control
Panel should not be necessary.
● Avid Media Composer may occasionally take up to 15 seconds to quit. This is not an indicator of a problem.
● For the AJA device to be selectable for audio-only capture in the Capture Tool, it must first be selected in the
Capture Tool:
● Open the Capture Tool
● Select both the Video Input and Audio Input as AJA KONA or AJA Io
● Initiate your audio only capture
● For the AJA device to be selectable in the Audio Punch-In Tool, it must first be selected in the Capture Tool:
● Open the Capture Tool
● Select the Video Input as AJA KONA or AJA Io
● Close the Capture Tool
● Open the Audio Punch-In Tool
● Select the Input Device as AJA KONA or AJA Io
● Indefinite looping of the timeline with Open I/O plug-in installed may cause Avid applications to stop playback and
give an error message..
● Occasionally analog video input will not be detected correctly in the Media Composer Capture Tool. As a
workaround, play the source video when you start up Media Composer.

AJA Desktop Software – macOS v16.1 drivers and software for KONA, Io and T-TAP Pro - Release Notes | www.aja.com 34
Telestream Wirecast
● When configuring a multi-channel card such as Io 4K Plus, KONA 5, KONA 4, and/or KONA HDMI the inputs must be
configured first (using AJA Multi-Channel Config application), if you plan to use the live program output feature. This
will set the master clock for the card (either NTSC or PAL), otherwise the card will be set to 1080i-29.97 by default
and could cause the card to attempt a mix of PAL and NTSC clocks. Be sure to configure all of your inputs and
outputs in AJA Multi-Channel Config prior to launching Wirecast.
AJA TV
● AJA TV can no longer acquire AJA device.
QuickTime to DPX Translator
● QuickTime to DPX Translator crashes on launch. This results from QuickTime deprecation. Use a pre v15.0 version
of AJA Desktop Software if you need this functionality.
