In this scenarios, chroma keying facilitates the integration of talents and objects on larger scenes. And when using LED floors, as LEDs are light emitters, the shadows of the characters will have to be applied as a separate process. When the production requires wide shots and floors, it will require carefully designed props, otherwise the integration will not be as good as it should. When using LED video walls not only we may achieve a natural look, but reflections and refractions on live surfaces will look perfect in the scene, not mentioning that the LEDs also contribute to lighting the scene. However, we will always need to key out the talents and any element on the green screen, which has its own issues (spill, transparencies, reflections, etc). On the other side, as the content is captured “as is”, it may be difficult to add further changes, post-production or VFX.Ĭhroma keying is a mature technique that allows for greater flexibility, as we can have different elements of the scene as individual feeds, that can be combined at will. Also, using LED video walls makes chroma keying unnecessary, as the image will be combined directly, live, on stage. When producing live shows, LED video walls allow for creating virtual backgrounds the audience can see live, in context with the performers, not requiring an additional screen to see the combined image. And, of course, they do not exclude each other and can be used simultaneously. Both methods have its own pros and cons, and the production requirements will define which method is best for our needs. LED video walls in virtual production may have benefits over chroma sets, but they are not the response to every virtual production requirement. But XR, or extended reality, is more than just using virtual backgrounds on large video walls, as this idea of mixing virtual and real elements goes far beyond the virtual background application and can include other virtual content like AR, taking advantage of camera tracking to integrate all the elements in the scene.
