Virtual production has given filmmakers an extraordinary amount of control, but it has also made the stage itself part of the VFX imaging pipeline. A cinematographer can arrive with a carefully tested camera, lens package and colour workflow, only to discover that the LED volume has poor calibration, compromised dynamic range, mismatched panels or an unexpected interaction with the camera.
StEM3 is designed to identify those problems before the first day of principal photography.
The American Society of Cinematographers’ Motion Imaging Technology Council, or ASC MITC, has released StEM3, a free collection of standardised evaluation material created specifically for in-camera visual effects and LED-volume production. The assets are hosted by the Academy Software Foundation as part of its Digital Production Example Library and can be downloaded for testing, education and production preparation. The files include videos and UE5 scenes.
