New Features and Changes


* SRT In and Out
SRT - Secure Reliable Transport is a point to point protocol for fixed latency streams over an unreliable internet.
vMix supports multiple inputs (Stream Input) and up to 4 outputs in vMix 4K and Pro (1 output in all other editions).
Uses GPU acceleration where possible for H264 and HEVC streams. 2 stream PC encode limit applies on GeForce cards, CPU fallback available where not available on the GPU.

* More Audio Buses
A-B audio buses expanded to A-G for a total of 14 channels of audio (7x 2 channel pairs)
Audio buses can be routed to Master to use as groups by selecting the new M button in the audio mixer.
SRT supports up to 8 channels audio in or out. Magewell, AJA and Blackmagic support up to 8.
vMix AVI supports full 16 channel audio recording. (Master + A-G)

* Mix Input (4K and Pro only)
Add a "mini mixer" input to vMix with a dedicated Preview/Output bus, Cut button and Fade button.
Existing shortcuts can be used with a new "Mix" dropdown option to select from 1-4 where 1= main mix, 2= first mix input and so on.
Mix inputs support "re-entry" and can be used as Input MultiView sources without any latency.

* vMix Media Converter
Bulk transcoding utility to convert vMix AVI into ProRes compatible MOV files for use in video editors such as Final Cut Pro and Davinci Resolve.

* GT Text Bounding
Link rectangles, images and other GT elements to Text fields set to auto width and/or height.
This allows these elements to match the size of the text with an optional padding value on each side.

* NDI 4
NDI 4.0 support included with ability to record with zero CPU in MultiCorder to MOV and also playback these new MOV files directly from vMix.

* Added option to select either Output 1 or Output 2 for each stream through the Streaming Quality window.
* Facebook destination can now be used alongside other providers due to Facebook policy change.
* Improved codec support for video playback.
* Web Controller authentication support.
* Added ability to select a Row for each text field now in Data Sources.
* Added 2x zoom option to Vectorscope.
* Added Mixer and Lightcast streaming providers to Destination dropdown.
* Added Unselect All option when opening a Preset.
* Updated web browser input to V77 of Chrome. Older version still selectable from downdown for compatibility.

That is correct, the X,Y coordinates of all objects in GT are based on the top left corner which will not change as a result of WidthAndHeight.
We will update the documentation to note that the auto settings are not designed to be used with centered text.

Wowza Server can be a bit tricky to setup, but I can confirm it works.

Some things to try:

1. Setup the stream file in Wowza for SRT to a url like "srt://0.0.0.0:10000" where 10000 is the port.
2. set srtKeyLength to 32 and passphrase blank on both sides initially as a test.
3. In Wowza stream file actions, select the Connect this to stream icon, and choose the correct stream to connect it to
with MediaCaster type set to srt.
4. vMix should then eventually be able to connect.
If there are any issues on the vMix side you can check the Statistics window in vMix under the Overview or SRT tabs for any error messages.

Any news about the replay system?

Wasn't there a note saying, that it was supposed to be rewritten / refinded?

EDIT:

I've been watching the Fun Time liveshow and got an answer to this question. So I guess I'll have to wait for vMix 24, then. Any news on that release? :)

Hey!
I'm trying to connect vMix with Wowza.
But I'm unsure which address should be added into vMix Hostname. And what type (Caller, Listener or Rendezvous)?
I suppose when in vMix set as a caller it sends SRT stream to an hostname address (Wowza server) and then it's needed to add a localhost address or as you wrote "srt://0.0.0.0:10000" into Wowza's "stream", am I correct?
Anything else to be configure when stream is created and connected to "srt" in Wowza?

Because I've done all of this and PC with vMix won't connect to the Wowza server.

Thanks!

Similar problem as Quinton is having.

Configured vMix as SRT Listener: https://prnt.sc/pmzp1i
Added SRT input: https://prnt.sc/pmzpgl

I see only first frame of the video, audio works.

When I disable Hardware Decoding, I see first frame with artifacts: https://prnt.sc/pmzqx0
With Hardware Decoding freezeframe is fine.

UPDATE: When I stream SRT to my server and generate RTMP from it, video and audio both work fine.

UPDATE 2: When I generate SRT on my server and add vMix SRT as caller I get same freezeframe as on local network. When I open same address in VLC (srt://***.***.***.***:1111/?mode=caller) it works.

UPDATE 3: You should add Reset option to the SRT input as well.

UPDATE 4: I'm able to reproduce the freezeframe in VLC as well when I set ":network-caching=" too low

Also, setting the vMix as SRT Listener freezed vMix for about 30 seconds for some reason.

(About the docs as well. It says that both, Caller and Listener must have same Latency but it reality, SRT handshake checks both side's Latency value and uses the bigger number.)


UI bug: When adding SRT input and changing between Caller/Listener/Rendezvous Listener "Port" value will get previously entered Host value. https://prnt.sc/pmzxvc to https://prnt.sc/pmzy12

23.0.0.19

http://cdn.vmix.com/download/vmix23preview.exe

* Fixed frame rate detection issue on SRT input causing stuck frames.
* Fixed error sometimes when closing a Mix input
* Fixed SRT Out 2 still remaining active even when disabled.
* Streaming quality preset now defaults to 720p @ 2.5 rather than 360p @ 1.5
* Fixed error when setting an NDI Output to use an audio channel that is not enabled.

To get something decent (working) for SRT using Larix - set latency to 10

When selecting Caller for SRT input, you will need to enter the hostname in the box provided and the port in a separate box.
No srt:// etc needed, just the hostname (i.e domain.com) and the port (i.e 12345) in the provided boxes.

Sorry never used this before, but maybe you misunderstood, or I'm not explaining very well.
I am using Larix Broadcaster to send a camera into vmix.
On my phone when I use srt://192.168.1.119:1935 and set up a listener inside vmix along with port number and passphrase it works perfectly (over local network)
When I go into Larix Broadcaster and set up another connection over the internet, like srt:// myvmix computers IP address:1935 and try and send that to vmix then it says cant connect.

I know that port 1935 is open as I use it with rtmpminiserver to send rtmp feeds from Larix broadcster into vmix via NDI, just do not understand why it works perfectly over local network, but wont connect when I try to do it over the internet?
