The Production Studio 4K is a 1U, half-depth vision mixer. It has many improved features over its predecessor, including a significantly increased number of SDI inputs, better cooling, and front panel display and controls - allowing the switching of the three auxiliary outputs. | The Production Studio 4K is a 1U, half-depth vision mixer.

When the ATEM 1 M/E Production Studio 4K was first purchased, it was used in the permanent YSTV live rack from 2015 till somewhere around 2016 or early 2017 when it was moved, along with all of the other permanent studio equipment, into the second built OB unit (Skycaster) where it currently resides. | |||

However, newer control software will prompt the user to update the ATEM firmware. | ATEMs can be controlled by any version of the control software lower than its firmware version.

As YSTV does not (yet) have a physical mixing board, our control of the mutiview and the stream vision mixing is entirely done through the software. While this does work, it is not ideal due to having to use a keyboard to control software. While the possibility of buying a mixing board has been raised several times since the [[hist:HD Upgrade|HD upgrade]] in 2013, there has been no reasonable opportunity to do so since they're damn expensive. | |||
To rectify this problem, [[hist:Andrew Waddle|Andrew]] (the technical director after the 2019 AGM) had the idea for [[Scratch built video mixer|Mixer Mcgee]] which may or may not be a bodged mixing board in the future. | |||
===Connecting to an ATEM directly=== | |||
Sometimes YSTV finds itself in a position where it needs to connect to an ATEM without having a proper network connection in place. In this case, an ethernet cable can be connected directly between the ATEM and a laptop running the ATEM control software. To do so, first check the IP address of the ATEM using a USB cable and the ATEM Setup utility (the IP will be something like 192.168.1.240). | |||
Then set a static IP on the laptop. On windows: | |||
* Open '''Control Panel''' | |||
* Click '''Network and Internet''' | |||
* Click '''Network and Sharing Center''' | |||
* Click '''Change Adapter Settings''' | |||
* Right click on the ethernet adapter and select '''Properties''' | |||
* Select '''Internet Protocol Version 4''' | |||
* Click '''Properties''' | |||
* If the IP of the ATEM was 192.168.1.240, set the IP of the laptop to 192.168.1.1 and the gateway to 192.168.1.1 | |||
* Set the subnet mask to 255.255.255.0 | |||
* Click OK and close the adapter options menu | |||
You will then be able to connect to the ATEM using its IP address. | |||

===Keying=== | |||
The ATEM can do internal live chroma keying using the upstream Keyer along with Luma keying up or downstream. The chroma keying will allow for live green screen keying (provided the screen is well setup). As with all keys, both the Chroma and the luma keying require a pair of incoming video streams (fill and key) on top of the background where (for the chroma) the key is the green screen footage with the subject on it and the fill is calculated frame by frame as the cutout of the key. For the Luma key, the process is similar but varies. In this case, the fill is a graphic contrasted with its streamed background (white on black for example) where the ATEM will remove the background colour. | |||
While these features have been so far fairly under utilised, it is hoped that they will find more use over time and on some of the larger projects. | |||
