Welcome to the Live Video Production & Visual Presentation Reinforcement area of the WELSTech wiki!
Live Video Production is the use of video systems to show presentation and/or video program material to people who observe the event...
Usually there is a separate video program for each group of observers in the list above because those in attendance at an event may not need to see images of the event leaders on the big projection screen.
Other times,the exact same program material may be sent to both on-site and remote audiences (i.e. there is only one video program), especially when the event is large enough that those on-site benefit from the use of image magnification ("imag"), and there is only 1 video projection screen available. Imag is the technique of making event leaders more easily seen, by putting a video image of the event leader into the video program, using cameras that are zoomed up close to the body of the leader. If there is more than 1 video projection screen, then the matrix of video program mixes may become a bit more complex, but possibly very helpful.
Imag is not necessary in most WELS churches, so most WELS churches use the technique of having 2 separate video programs: one for the projector(s) in the sanctuary and another for broadcast (live streaming) to remote TVs on the church campus (cry rooms, fellowship halls, overflow rooms, etc.) and/or the Internet. Often, the sanctuary screen(s) are fed by a computer running presentation software, while the remote feed is fed by a simple video camera.
Some live video production systems are more complex, using multiple cameras and some way to switch between or mix the sources of video. See the page about Video Mixers, Matrices and Switchers for more information.
Navigation of this portion of the wiki
Use the sitemap/pagetree on the left side of this webpage to find related pages within this field. There is a lot of information here! We would like to point out the References & Tutorials page, designed for anyone who wants to learn. It contains something for everyone, from the very basics to the very complex, and offers advice regarding paths of learning. Also, if you are experiencing troubles with your sound system, then you might want to take a quick swing through the Troubleshooting & Case Studies page to see if any solutions might match your situation.
Remember: The Live Video Production section (where you are right now) focuses upon the technology and skills necessary to help event attendees to clearly see allevent visual programming, plus focus upon the technology and skills necessary to produce an event's video program material itself. The Podcasting, Recording & Live Streaming section will help you to figure out how to get that video program material recorded and/or interfaced to the Internet.
For information regarding presentation software, please visit the Planning for Worship Services, Seminars & Presentations section of the wiki. The reason this information is not included here is because presenters and presentation engineers alike typically need to spend an enormous amount of "studio production" time creating the presentations. This section of the wiki does not address "studio" operations, only "live" operations. Note, however, that this same presentation software is an important tool that is used during events. Good news: instructions regarding how to interface your computer to the live video production system are included in this live video production portion of the wiki.
For information regarding how to record or live-stream anything (e.g. sermons, worship services, high school basketball games, etc.), please visit the Podcasting, Recording & Live Streaming section of the wiki, found in the sitemap/page links on the left side of this webpage.
May God bless your efforts to share the Word, and may others see your good deeds and praise your Father, who is in heaven!
