VT Guest is designed to enable remote anchors and speakers to contribute to a production, usually via a dedicated setup or shippable kit. A great example of how an entirely remote video production workflow was built for anchors contributing daily to a TV show is available in this case study.
VT Guest provides bi-directional connectivity between the contributor and the studio.
Unlike The Guest Link, the VT Guest application uses our SRT-based protocol and also supports GPU-powered encoders: this increases transmission reliability and streaming performance. Due to browser limitations, the web link is limited to the WebRTC protocol and CPU-based encoders.
VT Guest only works with a Partner license with the same ID as your license used in studio. See what is a Partner license here and how to create or obtain it here.
Download the VT software package from the My Account section of the Web Control Panel
Unpack it and delete your license file with a .JSON extension from the unpacked VT folder
Put the partner license .JSON file into the unpacked VT folder
Pack the folder and send it to your Guest
Please avoid sending folders with Video Transport apps over Google Drive or other cloud file hosting services unpacked. Some file systems can corrupt the files and the software may not work correctly after that.
Here is how the VT Guest looks like:
1
Access ID. Value required to receive the particular stream from the VT Publisher and send the Guest stream to the VT Receiver
2

Ready (NDI Connected). It means that VT Guest is connected to the VT Receiver, Output was started to NDI and NDI received by another app or device, but not broadcasted further.
On Air. It means that VT Guest is connected to the VT Receiver and Guest feed output to SDI, Virtual, NDI. In case of NDI it means that is broadcasted from device or app that did receive NDI output from the VT Receiver.

Using the context menu of the selected channel, select “Copy Access ID”.
Launch the VT Guest application on the required machine and choose the video and audio source you wish to contribute with and desired bitrate.
Paste into the "Access Link/ID" field the value from the source in VT Publisher and hit "Start”.

Once done, the feed from VT Guest will be available in VT Receiver. A return feed will also be sent to VT Guest from VT Publisher.
The receiving side (such as a studio or MCR) is in control of the transmission parameters (protocol and latency can be set via the VT Receiver app).
