2D Playback for In-Camera VFX in Unreal Engine 5.1.0

With the recent release of Unreal Engine 5.1.0 (preview) comes heaps of new and improved virtual production features that simplify LED stage playback and operation. One of which is the improved workflow for 2 & 2.5D video playback for in-camera VFX. Epic has added a mixture of new streamlined media management tools, and optimized 2D playback workflows, all to aid in reaching higher framerates, greater resolutions and deeper colour depths.

In this latest GODBOX video tutorial, we show you how to set up the new UE EXR video playback workflow.

On-Set Facilities (OSF) are an industry-leading Unreal Engine Virtual Production Studio that deploys and manages on-set UE VP pipelines for some of the world’s top content studios and production companies. OSF is the developer of GODBOX, the latency-optimised computer platform developed especially for on-set virtual production and VFX.

OSF is championing open technologies such as Unreal Engine for on-set virtual production and VFX. If you are interested in VP Stage Operation, Camera Tracking, or just skilling up in VP workflows, OSF now offers one-to-one or group virtual production pipeline training, running courses both on-set and remote, teaching the latest VP pipeline using UE5.1.0

EXR Tiling & MipMaps

Video plates are an essential part of in-camera VFX and often require the highest resolutions and deepest possible colour depths. These requirements come at a heavy processing cost, Unreal Engine 5.1.0 combats this with the addition of tiling and mipmaps for EXR image sequences.

What are Mip Maps? – Mip Maps are pre-calculated, optimized sequences of images, each of which is a progressively lower resolution representation of the previous. Mip Maps are utilized to increase rendering speeds and reduce aliasing artifacts. Mip Maps are a pre-allocated resource and require sufficient RAM to fully utilize.

In the context of EXR playback in UE5.1.0 this optimized image processing method allows the engine to stream and render only visible tiles within a viewport and then decode the same tiles as they become inactive, saving precious frames during production.

Simplified Media Management

Previously, setting up media for playback in engine was a cumbersome and less than ideal experience. With the introduction of the new “Media Plate Actor” Epic has streamlined the process for media management and rendering.

The “Media Plate Actor” provides users with the ability to simply drag and drop media assets into a scene and then control that same media asset from it’s own details panel. Providing direct playback controls, various projection meshes and auto play options.
