Is Radi an app for creating web sites?
Not quite. Radi is not a site-builder application like Sandvox or Dreamweaver which allow you to manage an entire site consisting of multiple individual pages. These apps mainly concentrate on providing visual templates and text editing similar to a word processor.
Radi is designed for creating timeline-based content and graphics that you can then publish on the web. In this sense, Radi is more like a hybrid between a video editing application and a graphics application.
Anything that you make in Radi can be published using the latest HTML5 web standard. Radi documents are published as easily embeddable HTML files, so you can use Radi to produce things like animations, video sequences and interactive banners that are then incorporated into a larger web site. (Check out the Embedding Radi tutorial for more info.)
Of course web pages published from Radi also work on their own, you don't need to embed them. So if you don't need advanced site management, you could build an entire site in Radi. The interactivity features in Radi allow you to keep several "pages" on the same timeline, and jump between them according to button clicks or other events.
How does Radi compare to other apps like Edge and Hype?
Edge and Hype are more concerned with managing a site structure and creating transition animations, whereas Radi is more about designing animations and creating videos. It's entirely possible to use them together - for example, you could embed a Radi animation into a website created in Hype.

What's the difference between elements and layers in Radi?
Briefly, elements are the components actually seen by the web browser. When you create a video element, a matching <video> tag will exist in the published document. Same for canvas, image, and HTML block (the last is just a freeform <div> element, which can contain any kind of HTML text).
Where are the image filters?
Radi includes a powerful effect design system called Conduit. It is like a filter creation kit that you can access directly within Radi. Conduit includes dozens of image filters, and more can be installed as plugins.
There are two ways to apply a Conduit filter:
- To an individual layer. In the Inspector, choose "Enable Conduit effect". Then click "Edit in Conduit Editor" to access the Conduit Editor window.
- As an Adjustment layer. Create the adjustment layer by clicking the button below the timeline, within the "Content layers" box. (Note that adjustment layers can only be applied to image or video elements. They don't work inside canvas elements because it's not possible to render these effects in realtime on a web page using the currently available web programming interfaces.)
The Conduit Editor is a node-based effects system. To find out more, please check out the Conduit FAQ.
