  5. What is “podcasting”? • “Podcasting” is the act of producing a podcast • Listening to a podcast isn’t “podcasting” • Remember, listening to a radio or television broadcast isn’t “broadcasting” • “Podcasters” are those who make podcasts, not those who listen to podcasts

  6. What is “a podcast”? • “A podcast is a web feed of audio or video files placed on the Internet for anyone to subscribe to.” • “The subscription feed of automatically delivered new content is what distinguishes a podcast from a simple download or real-time streaming.” (http://en.wikipedia.org/wiki/Podcasting)

  7. What is “a podcast”? • “Internet talk-radio” • Regularly created • Daily, Weekly, Bi-Weekly, Monthly • MP3 + RSS 2.0 feed with enclosure tag • A link to an MP3 audio file that’s sitting on a web site is not a podcast • A RealPlayer audio file is not a podcast • What’s an RSS feed? • RSS is an HTML-like format, for computers

  8. What is “coursecasting”? • “Putting audio of a lecture online” • Might be done as a podcast, or maybe not. • So, many professed “podcast” desires might be fulfilled with a simple audio file uploaded to a web server • Students could manually download and save MP3s onto a portable MP3 player

  9. Podcasting and iTunes • iTunes’ “podcast directory” is (just) one means of finding and receiving podcasts • For a podcast to be there, it has to be a genuine podcast (RSS 2.0 + MP3) • Remember, you’re then in Apple’s hands for trying to get things listed properly • (Though, if a student’s local workstation is configured accordingly, any MP3 file download will appear in iTunes)

  10. Videocasting • Videocasting? • Vidcasting? • Vodcasting? • Video Podcasting? • Video Blogging? • vlog?

  11. What’s the iPod Video use? • H.264 video: up to 768 Kbps, 320 x 240, 30 frames per sec., Baseline Profile up to Level 1.3 with AAC-LC up to 160 Kbps, 48 Khz, stereo audio in .m4v, .mp4 and .mov file formats • MPEG-4 video: up to 2.5 mbps, 480 x 480, 30 frames per sec., Simple Profile with AAC-LC up to 160 Kbps, 48 Khz, stereo audio in .m4v, .mp4 and .mov file formats

  12. Photocasting • iLife/iPhoto • Flikr • FlimLoop.com

  13. What’s the connection to Blogs? After all, that’s in the session title, right?

  14. How do Blogs relate to all this? • Blogs are a typical, common venue for regular commentary that’s provided to the planet through the web. • Blogs are a typical, common “engine” for creating an RSS feed. • So, you start with a “blog” and add things (audio, video, photos) to it.

  15. How can I do this? Or, “Could my faculty already be doing this?”

  16. How to get started podcasting Recording • Adobe Audition (PC) • GarageBand (Mac) • Audacity (Mac/PC/Linux and free!) • Quality Tips: • Compression • Normalization

  17. Original Compressed Normalized

  18. How to get started ‘Casting Publishing • OurMedia + Blogger + FeedBurner • OurMedia: Host the Creative Commons MP3 • Blogger: Provide the (Atom) feed • FeedBurner: Clean up the RSS feed • …and faculty might be doing this already!

  19. Innovations • Enhanced AAC (slideshow) • Pairing MP3 with SMIL (Mac/PC only)

  20. From one-way to two-way • So far, we’ve been talking about faculty publishing their materials out to students • Is there more? YES!

  21. Audio Collaboration! • Phone in to podcasts? • Like “community voicemail” but more convenient • An advantage to students who don’t want to raise their hands in class, but don’t feel confident expressing themselves in writing (e.g. in a discussion board) • (AudioBlogger + Blogger + E-Mail)

  22. Written Collaboration • Discussion boards or e-mail DLs are an early version of this, of course • Group blogs • UST Journalism class launching a community newspaper using MovableType blog server • Wikis

  23. Innovations • Combining streaming video with a blog that advances at key points in a timeline • (Microsoft Producer + hosting + Blogger) http://www.emlarson.com/gusday/vidlog-gusday2006demo.htm
