Audiovisual Field Testing: Projection.

Report on AV Technology: What Works Well in the World of Multimedia Presentations (and What Could Work Better!).

CONTENT ASSESSMENT - PRESENTATION TECHNOLOGY - LIVE EVENT MULTIMEDIA

In my travels as a presentation AV and multimedia playback specialist, I continually face AV challenges and offer solutions during live events. During the last twenty years, I've been performing live, presenting material in front of groups and running the technical side of live performances, public speaking, multimedia playback and I know what works and what doesn't work.

Over these years, I've worked on many film and video projects as writer, director, camera person, actor and editor, and that experience has made me very interested in helping people assess their live presentation content. Whether it's a business presentation, live performance or film screening, I am very interested in what the end user experiences. In AV planning and content assessment, I am not a critic, I am the ultimate end user and I tell it like it is.

I'd like to start this AV field report with my technology choice for projectors:

Canon LV-7255 (and others in the LV series): This is my projector of choice. I've used several LV projectors and I like them all, especially the newer ones. The brightness is great for presentations of up to 150 - 200 people (with stereo screens on Dalite FastFold 7.5' x 10', front projection screens). I use longer VGA cable runs of 25 - 50 feet, so I use a Kramer D.A.(distribution amp) for the stereo display, but I have even run these projectors through a daisy-chain (one connected to the other) and a 50 foot VGA cable with no D.A. and I get great results every time.

I've really put these projectors through the paces and two of the reasons I rely on them are because of the manual zoom and the manual focus. It would be nice to have a horizontal keystone control, but the vertical control, especially auto-keystone, works very quickly and well.

Like many projectors I've used, when computer inputs are hot-swapped, you may end up with horizontal sync issues that result in the side of a presentation being cut off, but that is easily correctable with the 'auto PC' button on the top of the unit. I know it would be best not to hot-swap and have all computers hooked up to a seamless switcher and ready to go, with all resolutions set to the default 1024x768, but I am talking about the real world, where things are set up and swapped at a moments notice. Therefore, I need a projector which does not give me grief on the road.

Stay tuned for more!
