If anyone is looking for stock elements for Media 100, consider the offerings from Rampant Design Tools. I bring this to your attention because Rampant "dares" to mention Media 100 in many of its product descriptions.
Browse rampantdesigntools.com and while you are there, put in a request for Boris RED templates and say how much you appreciate the mention of Media 100. Rampant is always having sales so make sure that you sign up for the newsletter.
Hi Gerry. Anything on the Rampant Design Tools website should work with Media 100 as advertised. The exception, of course, would be the After Effects templates. You would have to have After Effects to take advantage of the templates.
Note that some of the products are backgrounds, so alpha channel does not come into play for those, but other products should work just fine, taking advantage of the alpha channel in Media 100. The head guy at Rampant says he is a Media 100 supporter and will continue to be a supporter. So you should be able to buy Rampant Design Tools products with the assurance that they are compatible with Media 100.
