NOTE: At this feature relies on Adobe Flash Player for support, a number of restrictions and
limitations, particularly with audio apply.
To bring in RTMP streams, consider using the Stream input instead with the VLC dropdown option.
Flash Settings
URL
A URL can also be typed in if it refers directly to a SWF file.
e.g http://www.example.com/test.swf
RTMP Streams
RTMP Streams can be loaded into vMix in the following URL format: rtmp://web_site_url/live/myStream
Refer to the documentation of the streaming server for the correct URL format for your particular stream.
RTMP Buffer
The RTMP Buffer can be configured to assist with either low speed connections or low-latency streams.
Set this to 0 if you have a fast connection and want the least amount of delay possible.
Performance
Converting FLV files prior to another format such as AVI prior to use in vMix may result in better
performance.
Alpha Channel
The alpha channel transparency within the SWF file is fully preserved allowing the use of Flash Animations
as animated overlays.
(For example an animated watermark or logo)
Flash Mouse Input
vMix will automatically send any mouse movement or clicks from the Preview / Output windows directly to
the flash control.
Flash will also receive mouse input if it has been setup as an MultiView Overlay on top of another input.
This allows for the possibility of using a transparent flash based drawing control, to enable drawing on top of
another input (such as a Video Delay for Sports)
Virtual Set
The Virtual Set features provides the ability to integrate a chroma keyed live camera and other graphic
elements into a real-time 3D rendered virtual set.
This virtual set can then be smoothly zoomed and panned just like in a live television studio.
Setup
Choose from one of the built-in Virtual Set presets to add it to vMix.
Each will show a placeholder image giving an idea of where the camera and other elements will be located
within the virtual set.
Control
Each Virtual Set has two tabs that can be used for customisation.
