Because of the size of video files, transferring and transcoding takes up time and computing resources, so is best done as a batch process on a number of video files during a break or after the day's capture session ends. Ensure you transfer, transcode and then delete the .vvid files regularly to avoid filling up your SSDs.

To enable you to transfer and transcode reference video files, Nexus provides the Show File Transfer/Batch Processing interface, which you access via a button on the Data Management toolbar at the top of the Data Management tab.

You can transcode and transfer reference video files to the Nexus host PC that have been produced by one or more Vicon Vue cameras or FLIR cameras, and recorded to separate drives on the host PC.

Vicon video cameras are easiest to configure and offer higher frame rates than other supported video cameras.

Video files are large, so as part of the transfer process, you normally select a codec (Compressor/Decompressor) format to reduce the video file size. The selection of an appropriate codec and codec settings ensures the maximum reduction in file size, while minimizing any reduction in video quality.
