Frequently asked questions about remote video production with Video Transport, the most straight-forward point-to-point streaming tool.
There are several ways that Video Transport is used by customers. Here's a good place to start learning about Video Transport use cases.
Generally, one channel is one active transmission, but there are some exceptions. Please refer to this page for Video Transport licensing details.
To do this, you will need to configure mix-minus audio routing in the background (follow the link to learn now).
As of today, VT Publisher, VT Receiver, VT Server and VT Guest are available for Windows only.
But the Guest Link, the Web Preview, and the Control Panel can be run in a browser on a Mac.
Video Transport supports 4:4:4 and 10-bit color space while using Blackmagic Design capture cards. 4:2:2 is not supported.
VT does not have built-in comms features, although some users simply route the intercom via an extra audio channel, which can be selected on the receiving side (read more on audio routing).
However, we suggest you to deploy a separate intercom system (ideally, running on separate hardware): for instance, if you lose the video feed and need to troubleshoot, you will also lose the intercom and won’t be able to do that. So it’s better for reliability reasons to separate video transport and intercom. One solution we suggest is Unity Intercom, but there are others available as well.
Even if you set 50 Mbps as your streaming bitrate, the encoder will use only the maximum bandwidth that is needed for this particular content. For instance, if the input is an upscaled SD stream or a white wall in 4K, a lot less bandwidth will be required to transmit this stream in it's original quality.
If you have made sure that you have the bandwidth you need on both locations, the reason may be that the connection to our TURN server is not good enough. If this is something you observe, please reach out and we will look for a solution. This is valid only for WebRTC connections.
There are no limitations for this in the app itself, but the performance of your PC and GPU card are usually limited. Please check our post on system requirements.
Yes, and there are two reasons:
- 1.The apps have access to the H.265 codec (see technical requirements for hardware details). The browser-based implementation is limited to H.264 and VP9.
- 2.The apps use the SRT protocol with tons of improvements done by our team. In the browsers, we are limited to WebRTC.
The benefit of the Guest Link is that it works on all platforms including mobile devices.
This option is not available in any of the Video Transport apps, but it is easy to do using Direct Take – our multi-channel video recording solution.
You can use Dante Virtual Soundcard in WDM mode or ASIO modes and use Dante audio as the External audio for video sources or Extra Audio Output device.
Video Transport's latest version of connection protocol has numerous improvements: faster connection establishment speed, a more robust packet transmission algorithm, and a bottom layer for the future connection bonding option.
One essential part of the VT 2.0 connection protocol is the introduction of VT Gateways to establish connections in those cases when a direct connection can not be established.
