If you have your own web site, QuickTime Pro makes it easy to take video snippets off your digital camera and post them there. Its "Export for Web" option under the File menu presents you with some sophisticated publishing options... except now they're as easy to implement as checking a box.
The process couldn't be simplier. Open the movie you want to publish. Choose "Export for Web" from the File menu. Select the options you want: iPhone (WiFi), iPhone (cellular), and/or Desktop. Choose as many as you want. When you hit the Export button, QuickTime will create a folder with the different versions of the movie in there. It also creates a web page with instructions for publishing to your site.
My little bonus tip is this. Open that web page of instructions in your text editor, change the text to what you want to say, save the html file as a new name, and upload the entire folder to your web server. That page contains all the scripts you need, perfectly formatted, and pointing to your movie. As long as you leave everything in the same folder, you're set.
That's how I created this version of A Visit to the Tampa Aquarium. It is viewable in a web browser, on Apple TV, or on an iPhone. The built in script identifies what type of device is accessing the page, then serves the appropriate movie for that device. It's really quite clever.
You already know that I'm a big fan of the movie mode on our digital cameras. Now sharing those movies on your own web site is as easy as capturing them in the first place.
