Blackmagic Design ATEM SDI Switcher

Developed for multicamera live broadcasting to the internet or broadcast uses, the space-efficient ATEM SDI switcher from Blackmagic Design.
it offers gaming systems, corporate PC streams, or HD bodies a four-input live-production switcher with a built-in control panel.
The four SDI sources are provided on the rear of the chassis and they source up to 1080p60 footage.
Two 3G-SDI feeds are valuable for a projector or outboard monitor, a USB Type-C feed for streaming up to 1080p60 footage to a computer, and a RJ45, 10/100 Ethernet port for setup management, off-site control, and upgrades.
ATEM SDI is currently available with
The control surface contains easy-to-view, backlit control buttons to permit selecting camera sources, controlling transitions, keyers, parameters, and the DVE.
The ATEM Mini integrates upstream and downstream keyers, an enhanced chroma keyer, two linear/luma keyers, a DVE transition keyer, a response generator, and two colour generators.
There is additionally media subject support for fill and key pictures, which accommodates up to 20 stills in PNG, TGA, BMP, JPEG, and TIFF formats.
The SDI feed handles a minimum of 1366 x 768 definition for observation your stream. It also allows the ATEM Applications Control Panel via Ethernet, and the unit provides support for control and configuration through the ATEM SDI.

Transitions: Guide

Provided transitions include:

• Cut: When you press the cut button, ATEM instantly changes from your current program source to the preview source. Cuts can be performed by directly selecting sources or by pressing the cut button to switch to the next source.
• Mix: The mix, or dissolve, gradually transitions from one source to the next by creating a smooth blend. You can set custom timings to manually blend the transition.
• Dip: Just like mix transitions, a dip transition is a gradual blend that includes either a solid color, graphic, or another clip between the two video sources. Dips to black or white between sources are the most popular, or you can use logos or sponsor graphics.
• Wipe: Built-in wipe patterns include circles, diamonds, squares, and more. Shapes and patterns can be inverted or softened, and can even have customized colored borders.
• DVE: With the powerful built-in Digital Video Effects processor, or DVE, you can push, spin, squeeze, or swoosh your live video from one camera to the next with incredible built-in transitions. DVE transitions can be flip-flopped and reversed, giving you even more transition options.

ATEM SDI Upstream Keyer: Guide

Layer live footage over other footage inputs or graphics with the Upstream Keyer. You can use luma principal, linear principal, pattern principal, or shoot against a green display and use chroma principal to instantly composite the footage over virtual locations.

• Luma key: Luma keys work best with high-contrast images, like white elements on a black background, so you can use the contrast to cut the black background and replace it with live video or graphics.
• Linear key: Get clean, high-quality results with linear keying by using two separate sources for the fill and the key to create one video image. The fill signal contains the video to be stacked over the background, while the key signal contains a gray scale mask to cut out, or mask, the area to be filled.
• Chroma key: Used every day for TV weather forecasts, chroma keys are a powerful way of combining live images in real time. The presenter typically stands in front of a green or blue background and the chroma keyer will remove only that color and combine it with another image, such as a video or graphic.
• Pattern key: Combine live images with any of the built-in wipe patterns to combine live images or graphics with geometric shapes. You get full control over softness, symmetry, size, and position to create unique picture-in-picture effects that can be transitioned to as easily as any live source.

ATEM SDI switcher Downstream Keyers: Guide

The ATEM SDI switcher incorporates one downstream keyer, so you can attach high-quality graphics such as logos, bugs, and titles from the built-in media subject over the live stream program feed. Downstream keyers are the last layers of keying, so they overlay all footage switched to the main program feed.

sound Mixer

The built-in audio mixer lets you control both body and outboard audio with accuracy level and equilibrium adjustments on all six provided audio sources and two channels. The mixer integrates selectable On/Off/Audio-Follow-Video per channel, plus it has standalone gain control per channel, level and peak metering, and new Fairlight audio enhancements such as compressor, gate, limiter, six channels of parametric EQ, and master gain control.

ATEM SDI switcher Media Player: Guide

Eliminate outboard character generators by storing up to 20 broadcast-quality RGBA graphic files in the media pool. The one media subject appears as source inputs to your switcher. You can transition to graphics as full-frame footage, or feed them to the keyers for overlaying footage. Popular picture formats such as PNG, TGA, BMP, GIF, JPEG, and TIFF are supported.
