Welcome to INNOVA, the new online on demand learning platform brought to you by ESTA and USITT. Whether you are seeking continuing education credits or simply wish to increase your knowledge, INNOVA’s programming allows you to view courses from anywhere at anytime.
This class will cover Basic Truss Theory including the components of a truss, the function of each and how those components work as a unit to safely support and transfer loads. This is intended to be the first in a series of presentations on truss and truss systems covering safe use and application, selection, inspection and information on Ground Supported Truss Systems, indoor and outdoor.
This basic level lecture reviews best practices for entertainment rigging situations, shows examples of incorrect rigging, and suggests some resources available for further training. By the end of this review, an attentive person should be able to: a) identify questionable and potentially dangerous rigging situations in an entertainment rigging system, b) work as a member of a theatrical rigging team, and c) source professional assistance for issues that exceed their knowledge base.
A comparative analysis of flat production techniques. Which are the best for tall, wide or irregularly-shaped flats? What are the best ways to rig or move vertical scenery? These questions and more will be discussed.
The purpose of this course is to introduce you to the field of structural engineering. The course will cover three topic areas: What is Engineering, The Language of Engineering and Engineering Means and Methods. The goals of the course are:
To help you understand the process that an engineer uses to analyze a structure.
To provide an understanding of engineering terms so that you can clearly communicate with your engineer.
To introduce you to basic engineering concepts for static structures as a basis for further work in parts 2 through 4 of this series.
The other courses in this series will cover:
Part 2: Loads, Reactions & Free Body Diagrams: What are the forces
Part 3: Strength of Materials: Why things are strong
Part 4: Behavior of Structures: Beams, Trusses & Columns
Loads may not have changed but the way we evaluate them has. The entertainment industry has shifted away from relying on single, large factors of safety, instead applying appropriately smaller design factors to understood loads. In this session, the presenters will define terms such as characteristic, dynamic, and peak load, and they will demonstrate how these concepts are used in engineering calculations.
These principles form the basis for current entertainment machinery Standards. This session is part of the Engineering Commission ‘s Mechanical Design Series with “Stage Machinery Brake Design and Selection“and “Emergency Stop Systems - How Safe is Safe Enough?”.
Building on Physics of Theatre sessions of previous years, this session will quantify common performer flying motion and use that information to determine the tensions in each system component. We will work through simple pendulum and traveling systems and discuss how torque and center of mass affect these systems. We will talk about terminal velocity and other limitations and concerns associated with free-fall. This session is led by ETCP recognized trainer, Verda Beth Martell, and Physicist Dr. Eric Martell for 1 ETCP renewal credit.
This video is a brief overview of one of ESTA’s most popular standards, E1.11, DMX512-A. This control protocol is nearly ubiquitous in the entertainment lighting industry, used in a host of luminaires, lighting effects, special effects, house lighting systems, video servers, and more. The standard is simple and effective, specifying everything about the protocol, including the structure of the data packets, the electrical interface, and the physical connectors. Viewers will get a basic overview of the standard and be informed where to download it for free, courtesy of ProSight Specialty Insurance.
The video is a brief introduction to the first of ESTA’s American National Standards. It explains what the intertwined problems were that the standard was written to address: people falling from wire rope ladders and OSHA inspectors having nothing to tell them about how people could use the ladders safely. The video briefly describes what is in the standard. It also tells the viewer where to get the standard for free courtesy of ProSight Specialty Insurance.
The video is a brief introduction into the second of ESTA’s American National Standards, now in its third edition. Truss and tower units are the basic building blocks of portable structures. The video outlines what the standard offers: minimum requirements and duties for module manufacturers and users. These requirements are all minimum requirements; doing less would be negligent.

This video is a brief synopsis of our largest, most complex standard: ANSI E1.17. That standard is a suite of documents that specifies an architecture, including protocols and language, which may be configured and combined with other standard protocols to form flexible, networked audio, lighting, or other control systems. It's big: about 2 megabytes as a ZIPped archive of PDFs and a directory of related DDL files as DDL and HTML. Viewers of the video can find out where to download the standard for free, courtesy of ProSight Specialty Insurance.
This video is a brief synopsis of an extremely brief standard: ANSI E1.16 - 2002 (R2017), Entertainment Technology - Configuration Standard for Metal Halide Ballast Power Cables. This standard prescribes which contact should be used for the safety ground for detachable power cables on 6 kW, 12 kW and 18 kW metal-halide lamp ballasts. Viewers of the video can find out where to download the standard for free, courtesy of ProSight Specialty Insurance.
The video is a brief introduction into the third of ESTA’s American National Standards, now in its fourth edition. Zero to ten-volt analog control is an old method, but it's still used, and this standard helps define the controller-current-source method used in the entertainment industry as distinct from the controller-current-sink method used with dimming fluorescent ballasts. The video outlines the what the standard covers: transmitter specifications, receiver specifications, cabling, connectors, and marking. It also tells the viewer where to get the standard and the companion document, the Application Guide for ANSI E1.3, for free courtesy of ProSight Specialty Insurance.
This video is a brief overview of ANSI E1.8, a standard for the structural integrity of loudspeaker enclosures that are suspended overhead. The standard was written to mitigate the risk of flown speaker enclosures breaking and dropping debris. It is geared towards loudspeaker enclosure manufacturers, but being aware of a manufacturers minimum requirements could be beneficial to a user’s work. Viewers of the video are offered instructions on where to download the standard for free, courtesy of ProSight Specialty Insurance.
The video is a brief introduction into the fourth of ESTA’s American National Standards. The standard applies to permanently installed, manually operated but counterweighted systems of stage rigging hardware for the raising, lowering, and suspension of scenery, lighting, and similar loads. It doesn't apply to performer flying, or to raising or lowering people.
