Key capabilities include HDMI 1.4b input and USB-C output to phones or tablets, internal SD recording of proxy files, and wireless transmission to up to four mobile devices or Pyro receivers. The unit streams UHD 4K30 or lower resolutions with low latency and supports H.264 proxy recording as well as ProRes bridging when used with iOS devices. Built-in timecode detection enables reliable proxy linking in common NLEs.

Connectivity and compatibility cover Android and iOS devices and integration with HollyView and HollyLink software. HollyView provides real-time monitoring, recording, annotation, and direct social streaming via RTMP or platform SDKs. HollyLink enables tethered image transfer to Capture One on macOS or Windows while the device is connected by USB to the camera and to the computer by Wi-Fi.

Typical applications include remote monitoring on set, live streaming via smartphone-hosted RTMP, multi-operator monitoring across phones and receivers, and backup proxy recording for editorial workflows. The Vcore supports wireless timecode embedding and proxy creation to simplify dailies and edit preparation.
