The Blackmagic WebPresenter and ATEM devices stream straight from SDI, without a computer in between. The same generic profile works for the WebPresenter HD, the WebPresenter 4K and ATEM devices.
In Auto Mode the WebPresenter switches profiles on its own. In our experience 4K mode needs at least 20 Mbit/s, which can trigger automatic blocking during peak loads. Unless you really need 4K, we recommend HD.

Download the WebPresenter profile

Get the generic XML setting from the download page. It works for WebPresenter HD, 4K and ATEM.
These steps apply to both dfine.io products that livestream — Streaming Classic and Review. The encoder setup is the same; only where you copy your ingest URL and stream key differs by product. See Where do I find the ingest server URL?.

​
Add your ingest URL to the profile

The downloaded XML ships with a placeholder for the server address — you must replace it with your own dfine.io ingest URL before loading it. Open the XML in any text editor, find the <servers> block, and swap ENTER YOUR OWN INGEST URL HERE for your ingest URL (see Where do I find the ingest server URL?), then save. 
<servers>
    <server>
        <name>dfine.io - Germany</name>
        <url>ENTER YOUR OWN INGEST URL HERE</url>
    </server>
</servers>
Prefer not to edit XML by hand? You can generate a ready-to-load profile with an online tool such as heretorecord.com/xml, then load that file in the next step instead.
