AVPro DeckLink

Bringing DeckLink hardware into Unity

AVPro DeckLink adds native support for Blackmagic Design's DeckLink hardware to Unity on Windows. It fits the point in a production workflow where Unity has to move video to and from dedicated hardware rather than stay inside standard media playback.

The package stays focused on that job. Broadcast standard video input and output are included, along with automatic video input mode detection, multiple inputs, low latency output, audio input and output, and support for up to 8K video input and output. Alpha channel output is supported too, which matters when the rendered result needs to carry transparency.

Handling live feeds, UI control, and compositing

The feature set goes beyond simple signal passing. Internal and external keyer support points to composited output workflows, while material mapping support gives the video a place to live inside Unity materials.

IMGUI and uGUI support keep the package useful alongside Unity interface systems, and the included example scenes and drag-and-drop components make the setup path more concrete inside a project. Automatic bit-depth detection is part of the current feature list as well, so the package can respond to the incoming signal without extra manual handling.

Compatibility across Unity versions and render pipelines

The current release is 1.9.11, dated 29 January 2026. It adds D3D12 support, Unity 2022 support, auto bit-depth detection, and DeckLink 8K Pro support. The release also requires the latest Blackmagic Desktop Video, version 15.3 or newer.

Compatibility is listed for Unity 2021.3.0 and 2021.3.45, with render pipeline support shown for Built-in, HDRP, URP, and Custom SRP in those versions. Render pipeline compatibility is specified for 2021.3.0f1 and 2021.3.45f2, and the feature list also states Unity 5.6 and above support. The original Unity version is 2021.3.0, and the package is delivered as a unitypackage with a 6.4 MB file size and 125 assets listed.

What the latest release fixed

The 1.9.11 notes concentrate on color accuracy, editor stability, and output behavior. Fixed items include incorrect BT.709 colour conversion, the DeckLinkManager GameObject not correctly disabling input and output, output memory leaks, a NullReferenceException on the second run in the editor, input changes from progressive to interlaced, and a red/blue swap issue in Unity 6.something with D3D12.

Two changes stand out during day-to-day use. Renderer Sync was added to input devices and defaults to on for smoother texture updates, though it can be turned off if it causes GPU contention. Renderer Sync support was also added for output, bringing the output side into line with the input side. The DeckLink SDK was updated to 15.3 as part of the release.

Where it fits in a production pipeline

This package fits where Unity needs to sit close to broadcast hardware, not just display video files. It is relevant for projects that need hardware-backed video input and output, keying, audio handling, and alpha channel output inside the same Unity scene.

For a production team, the useful part is the combination of Windows-only DeckLink integration, multiple inputs, low-latency output, and support across Built-in, HDRP, URP, and Custom SRP. That keeps it anchored to the part of the workflow where the rendered result has to meet external video hardware directly.
