Videro is one of those silent-but-cool application suites you've probably never heard of, but you may see it being used every day. I met some of the Videro team at WWDC, and they were happy to demo a little of what the tools do: electronic signage and interactive kiosks. If you happen to need an animated in-store (or museum) display, fed from a server, easy to set up and deploy, complete with iPhone access to check on the servers (so they say), then Videro is an impressive tool.
To start, Videro has a composition tool that allows you to drag and drop your animations, complete with images, video and audio. In fact, Videro has extensive in-app tools for cropping, rotating and otherwise "fixing" your assets for display. But wait, there's more! This isn't just Keynote all gussied up. Videro is designed for business, and a server application makes sure mission-critical displays are functioning properly. There's solid asset management support both in the client and the server applications, making sure your displays never fire off with a dreaded "black box of nothing" where a product shot should be.
Videro mentioned an iPhone app in the video but I have been unable to locate it in the store and a search on their website revealed nothing. Still, it wouldn't be terribly difficult to provide some baseline stats via password-protected web app. We weren't able to get Wi-Fi at our location, so some features weren't visible and this might have been one of them.
Unfortunately Videro's site mentions nothing about price. In my experience that means we're talking about an expensive solution, and likely a custom one for the high-end customers. If you're looking for something simpler, don't miss Dave's excellent post about using Keynote and Dropbox to create an updating and easy presentation solution that would work in a pinch.
