Putting It All Together
Once you have your sources prepared, it’s easy to make it work. First, select a mixer on Encore. On Layer B, choose your “fill” video (such as a camera source). On
Layer A, choose the “cut” video (the shape that is stored on your external graphics computer). Next, choose “Cut & Fill” as the key type, position the fill inside the
hole as desired, and then lock the two layers together using Encore’s “Join” mode. The two layers now move together as one. Repeat the entire process on another
mixer, to manipulate additional shaped PIPs.
Shaped PIPs in Concert
The “shaped PIPs” feature was put to excellent use on Tom Petty’s 2005 tour, in which the stage’s entire backdrop was comprised of geometric shapes, with LED strips
acting as borders between the shapes. Here’s the set designer’s goal was to fill each shape with a different video feed.
By using multiple Encore Video Processors in the “stacking” mode, 12 layers (mixers) of video were available. Encore’s output was routed to two rear-screen
projectors backstage. A shaped graphic (precisely matching the backdrop’s dimensions) was stored on a dual-head computer, and patched to every Encore mixer via
router connections. On each of the 12 mixers, the Key Cut & Fill feature was used to isolate a portion of the overall graphic, fill it with a unique camera source, and
visually position the shape in its respective cutout in the backdrop.
Finally, the very same shaped graphic (stored on a second dual-head computer), was patched to Encore’s Down Stream Key (DSK), and used to mask the entire output
with video black — thus preventing any light spillage in between shapes. This method also enabled all of Encore’s color and strobe effects to be used on any layer,
without restriction.
The result — one of the most visually dynamic concerts ever presented
— all as a direct result of the creative use of Key Cut & Fill.
