Support for FLIR video cameras

To meet the demand for high quality video in Nexus, support for video cameras has been extended to include FLIR Blackfly S video cameras.

For more information on selecting, setting up, and using FLIR cameras with Nexus, see the FLIR Video Cameras Setup Guide.

64-bit Nexus only

Nexus 2.13 is 64-bit only. In most cases, you should upgrade to this version to benefit from the latest functionality. However, in the following circumstances, you may want to continue using Nexus versions 2.12.#:

• If you need to run legacy VPI operations, (for example, proEMG), you must use a 32-bit version of Nexus, so ensure you use 2.12.# for post-processing.
• If you use a VDD (Vicon digital device file) that does not have a 64-bit version, continue to use Nexus 2.12.# until the vendor of your VDD releases a 64-bit version of the VDD. For information about the availability of the 64-bit version of the VDD, please contact the vendor.
  When you install the plug-in for your device, ensure that the 64-bit version of the VDD is correctly installed to the folder:
  C:\Users\Public\Documents\Vicon\Nexus2.x\DigitalDevices64\
  
• If you want to continue to use Basler cameras with Nexus, use Nexus 2.12.# or earlier.
• If you want to use the OpenGL solution for non-NVIDIA graphics processors. note that this is not supported for Nexus 2.13 and you should continue to use Nexus 2.12.# or earlier.

Codec changes

In Nexus 2.13, you can select only the H.264 codec when you transcode captured video files. Video data captured by Nexus (.vvid) that has been transcoded using H.264 encoding in Nexus 2.13 can be loaded, played, and stepped.

You can choose from five quality options, ranging from Best Quality/Largest File to Lowest Quality/Smallest File. Choose the option most suited to your application.

The H.264 codec is compatible with Theia.

To load and play back offline existing Nexus sample data .avi files that were encoded with ffdshow, ensure you have installed the 64-bit version of the ffdshow codec (DirectShow filters only, not the VFW drivers). This also applies to any codecs that were used for transcoding in previous versions of Nexus: to decode and display the relevant video, the 64-bit DirectShow filters must be installed.

The following functionality continues to work as it did in previous versions of Nexus:

• You can transcode video data captured by Nexus that is stored in .vvid files, using the File Transfer/Batch Processing interface (see Transfer and transcode digital video files in the Vicon Nexus User Guide) or the Transcode Video for Trial pipeline operation. This produces .avi files that are readable by Nexus without installing any codecs in addition to H.264.
• You can create overlay .avi files using the pipeline operation Export 3D Overlay Video.
• Workspace overlay .avi files can be created using the Export Workspace to AVI button in the workspace window.
• Existing .avi files associated with a video camera view can be recompressed using the pipeline operation Apply Codec to Video.
