iOS and macOS Apps Technical Support

 

NB: In many cases, problems with apps have already been fixed, so make sure you update to the latest version before troubleshooting.  Currently you will need OSX 10.10.5 or later for the Mac apps - earlier macOS versions are not supported.

 

NDI In General

Updated version of all our apps are available to address any issues. To be informed of updates in the Sienna NDI tools, subscribe to our news updates, by requesting the Free NDI Tools download.

 

NDI Monitor

If you are trying to upgrade NDI Monitor from the Apple App Store and it wont let you authenticate with your own Apple ID (it stick on another ID), you need to first delete ALL copies of the NDI Monitor from anywhere on your computer, then do a fresh installation from the App Store or from the Sienna website at http://sienna.tv/ndi

 

NDI Cam

The iPhone platform is powerful, but it's not a desktop computer. Consequently NDICam may not run at full HD / full frame rate in most cases. The Quality vs Speed slider provides a compromise between the 2 depending on your needs. Future versions of NDICam will include new developments in NDI which are expected to improve encoding performance and reduce network bandwidth. An important consideration when using NDICam is WIFI performance - NDI is a high data rate professional protocol which requires 50-100mBit of bandwidth. Most WIFI networks are capable of 50mBits (in ideal conditions) and more modern WIFI can do 100mBits (in ideal conditions) but there are many factors which can adversely affect WIFI performance and significantly compromise bandwidth.  WIFI congestion and interference is a common problem, particularly in locations where large numbers of cellphones are active with WIFI enabled (for example, in a Live event, or trade show). Using 5GHz Wifi can help with congestion since it is much less common so the frequencies are less polluted, alternatively try using a different Wifi Channel in 2.4GHz range. For critical environments, using a directional Wifi antenna can help significantly. Finally Apple's Airport WIFI access points appear to be *significantly* better at delivering high quality WIFI to iOS devices, perhaps due to some apple secret magic, so using an Apple Airport is always a really good idea.  Due to the glitch in NDI, you may find that some recent versions of TriCaster and other NDI systems may cease to see the NDICam output.  The solution will be to further update those systems past the glitch when it passes shortly, or revert them to the earlier version. Version 1.22 of NDICam is now available  to address the issue from our side, and to eliminate compatibility issues as much as possible across *all* receiver versions, old and new.

 

NDI Signal Generator

A bug in the original NDI code means that the 'low bandwidth' image from this app when in interlaced mode is a strange shape.  It may display OK in some apps, and squished in others.  Progressive mode and the HiRes stream do not have this issue.  A future version with updated NDI will resolve this.  If your receiving NDI device cant see the output from NDI Signal Generator, upgrade it past the 25th May NDI library, or update NDI Signal Generator.

 

NDI ScanConverter

Old versions of NDI ScanConverter may crash if used on the new iMac 5k in full resolution. The original version 1.0 of NDI ScanConverter Lite has an expiry date of 1st April, left over from beta testing and will not run after than date.  Older versions of NDI ScanConverter may run into a new behaviour of OSX called "Timer Coalescing" which may cause the video stream to stall when NDI ScanConverter is in the background. Update to the current version to resolve any of these issues.   Due to the glitch in NDI, you may find that some recent versions of TriCaster and other NDI systems may cease to see the ScanConverter output. The solution will be to further update those systems past the glitch when it passes shortly, or revert them to the earlier version, although a newer version of NDI ScanConverter available soon will also work around the glitch from the other side.  There is a bug where ScanConverter may crash or misbehave if you are running 2 or more instances of an application with the same name. This is addressed in the latest release.  Finally, we had one report of a problem with NDI ScanConverter on Mac OSX 10.10.2 - the NDI source did not show up at all.  Upgrading the mac to 10.10.5 solved the problem.

Version 2.01 and older of ScanConverter may experience poor quality for very large screens. This is resolved in version 2.11. If you are running an extremely high resolution screen, its possible you may have other issues - in this case please contact us.  Note that version 2.10 has a bug which affects users with 5K retina screens - upgrade to 2.11 if affected.

 

NDI Source (BMD)

Many modern BMD devices support the Auto format detection mode - so for these devices, select the AUTO setting in the format menu. Older BMD devices require that you manually select the mode corresponding to the incoming video source.  In version 1.0 of NDISource a bug means that the wrong source is identified, so when using older BMD Devices, select the menu item ABOVE the format you mean to select.  This bug is fixed in version 1.1 an later of NDI Source which is available.  Due to the glitch in NDI, you may find that some recent versions of TriCaster and other NDI systems may cease to see the NDI Source output. The solution will be to further update those systems past the glitch when it passes shortly, or revert them to the earlier version, although a new version of NDI Source 1.2 is now available and works around the glitch from the other side.

 

Tested Devices using El Capitan 10.11.2 and BMD Desktop Video 10.6.2, latest NDI Source:

UltraStudio Mini Recorder (Thunderbolt) - WORKING

UltraStudio 3D (Thunderbolt) - WORKING

Tested Devices using El Capitan 10.11.5 and BMD Desktop Video 10.6.8, latest NDI Source:

Decklink Duo 2 (PCIe, inside MacPro Tower) - WORKING

Other devices should also work - older devices which dont support auto format detection may need to select format in the menu.

WebCam for NDI

The current version of WebCam for NDI supports 16-bit audio. If you are using a device like a new MacBook Pro internal camera, which offers 24-bit and 16-bit audio options, only the 16-bit audio menu item will result in audio being passed to your NDI device (even though you may see the application's meters moving with 24-bit audio selected).  Select a 16-bit PCM audio mode and all should be well.

Tested Devices using Sierra 10.12.4

Logitech C920 HD

Apple iSight on 2016 MBP 15"

most other AV foundation compatible devices should also work

 

SDI ScanConverter (BMD)

SDI ScanConverter can display windows and regions of interest which are not 16x9 aspect ratio.  In this case, its possible to output the remainder of the screen with black, white, green (for a chroma key) or alpha - which can deliver a proper fill and key with supported hardware.  When attempting to output with background set to alpha, note that you will need a DeckLink or UltraStudio which supports external keying (ie with a Fill and Key SDI Output).  In some cases the card will need to be configured.  For example - when using Duo 2 card you must set device #1 to select SDI 1+2 in order to support a dedicated fill and key output.  Note that when the card is in this mode, you may find that the other background modes result in a blank output.  So if you want Fill and Key, set the card up with 2 x SDI outputs, then select Alpha background mode in ScanConverter.  If you dont want fill and key, then set the card to a standard configuration and select the desired background colour in ScanConverter.
