Vicon Nexus 2.16 is a point release that provides features and enhancements in addition to those that were included in earlier releases of Nexus 2. For more information, see Nexus 2.16 new features and changes.
This release also benefits from ongoing maintenance and includes a number of Addressed issues.
For workarounds for remaining issues, see Known issues.
Nexus is 64-bit only. In most cases, you should upgrade to the latest version of Nexus to benefit from the latest functionality. Before you upgrade from a 32-bit version of Nexus, note the following points:
The OpenGL download for non-NVIDIA graphics processors offered a potential workaround for Nexus 2.13–2.15. However, in Nexus 2.16, it causes adverse performance and display issues and may cause Nexus to stop responding.
For information on graphics cards that are supported for Nexus 2.16, see Graphics processors for Nexus.
Nexus 2.14 and later provided an updated version of ProEclipse so that the path to Vicon Polygon now uses the Program Files (x86) folder when called from a 64-bit application.

Nexus 2.16 supports native MP4 files and MP4 is now the default video format. This affects the following areas:
In Nexus 2.16, the default video transcoding uses H264 compression in MP4 containers. You still have the option to transcode using the same AVI outputs that Nexus 2.15 currently supports.
The option of choosing either MP4 or AVI formats is available in all the places that support the creation of video files, for example, in the Transcode panel and the Transcode Video for Trial pipeline operation.
For information on viewing compressed video, see Viewing video data.
Nexus 2.16 now loads video files that are associated with a trial in both MP4 and AVI formats. MP4 files must have been created in Nexus, and AVI support helps maintain backward compatibility with videos created in earlier versions of Nexus.
In the case of a trial that has multiple video files for the same camera, the most recent file is loaded, with MP4 taking precedence over AVI video files. In addition, video files with timestamps also take precedence over video files without timestamps.
Nexus 2.16 also supports the loading of trials which contain multiple video cameras that have a mixture of native MP4 and AVI formats.

Note |
In addition to the pipeline operation for transcoding video, described in Transcoding video files, the following pipeline operations also support the H.264 MP4 format:
Apply Codec to Video

New in Nexus 2.16, the video transfer list recovery feature ensures that the video transfer process remains robust to intentional actions (ie, moving your video data to a different location from where it was originally saved) or accidents (ie, the transfer list being erased or becoming corrupted).
To recover your video transfer list:
To populate any raw (VVID) files on the capture drives into the transcode list, click Rebuild Transcode List.
Nexus scans the active folder and looks for VVID files that are still located in their original capture paths.
Trials that are found with untransferred video files are added to the transcode list.
For more information about using video data with Nexus, see Work with digital video files in the Vicon Nexus User Guide.

In Nexus 2.16, updates to the IMeasureU panel make it easier to select and transfer your data. Additional or enhanced features have been added in these areas:
Two significant changes help you manage the data that is populated within your transfer list in the IMeasureU tab:
To remove erased trials from the IMeasureU tab:
In the Communications panel, select the IMeasureU tab and click Show Advanced.
The Sync trials with sensor button is displayed.
On the IMeasureU tab, select the IMU sensor.
Erased trials are displayed in red.
Click Sync trials with sensor.
You are prompted to confirm that you want to continue to remove the erased trials from the list.
Click Yes to continue.
In the Trial list on the IMeasureU tab, the red (erased) trials are no longer displayed.
To restore missing information to a sensor:
Click Rebuild Transfer List.
In the Rebuild Transfer List dialog, click in the Folder to process box, enter or browse to the folder to process and if required select Look in child folders to process all of its subfolders.
Note that the folder you select does not have to contain the trials, for example, the folder can be the parent of multiple session folders. In this case, you would select Look in child folders.
Click Continue.
The trial-specific data is copied and you can now download the restored information from the sensor.
To enable you to select data of interest more quickly than in previous versions of Nexus, the transfer list on the IMeasureU tab now provides options to filter the list of trials that is displayed.
