Podcast + Powerpoint = Slidecast Mashup

I mentioned Slidshare.net before -- it is a website where you can upload and share Powerpoint presentations. I have uploaded a few of my presentations, and have marked a few others as favorites.

Now, Slidshare.net has introduced "Slidecasts." Slidecasts are mashups of audio files and uploaded Powerpoint presentations. This is kind of like what Camtasia (Techsmith.com) does on your computer, and what can be done with Garage Band for audio podcasts.

Camtasia Studio creates a recording that includes both audio and synchronized video that is captured from your computer's microphone and screen. Camtasia is mostly used to capture the combined Powerpoint presentation and audio presentation for making training videos and capturing lectures. Output can be edited and saved in a variety of different format, including Flash. (Tegrity.com also offers a similar application, with searchable files that are stored on the Tegrity server.) The Apple computer program, Garage Band, allows you to attach photos and images to segments of an existing audio, or podcast, file. The result is in a proprietory format that is only viewed on Apple's Video iPods and on the Quicktime player on PCs and Macs. It is mostly used for creating "enhanced podcasts."

Slideshare's Slidecast requires that you have two things: (1) a Powerpoint presentation that has been uploaded to Slideshare.net [ppt, pps, opd, and pdf formats all will work], and (2) an MP3 audio file that is accessible somewhere on the Internet -- on a webpage or on a blog. (There are some free audio/podcast sites that might work for this, such as Gcast.com.) Slidecast is nice online application that allows you to mashup these two files by moving slide transitions to any point on the audio file.

The resulting Slidecast is very slick and can be viewed on the Slideshare.net website, or the code can be copies to place it on a blog or other website for viewing. Examples can be found on the Slideshare.net homepage, where a Slidecast of the Day is highlighted.

I have never used Camtasia, mostly because of the cost (I like free things). I do, however, record my lectures and presentations, which I sometimes use to create podcasts, and I lecture with Powerpoint slides. Slidecasting looks like something that I will definitely enhance the online learning of my student.

From the Slideshare.net website: "Slidecasting is a new multimedia format for viewing slide decks synchronized with an audio file. It is for conference talks, musical slideshows, audio picture books or whatever else you can imagine. It's really easy to create one, so get started now!"

NEW (30 Aug 07): I created my first Slidecast today. It was incredibly easy! Check it out here.

NEW (3 Sept 07): Edublogs.org has posted instructions for embedding Slideshare Slidecasts, and a couple of other slide show products, in your blogs: http://edublogs.org/embedding-slideshows-and-other-flash-stuff-in-your-blog/

Putting Lectures Online - Podcasts, Streaming, and more

I just returned from the 2007 Educause conference in Dallas, which had some 8,000 university IT and eLearning attendees, and almost as many vendors. There I learned of several companies in addition to BoxPopuli (see my previous blog entry) that offer classroom recording/podcasting products similar to BoxPopuli. My impression is that these tools are more robust (more features) than is currently offered by BoxPopuli, but then they may also cost a lot more.

To start, I suggest that you check out this online lecture at Mediasite.com. Yes, it is a sales pitch, but it gives you a good idea of what is possible with these lecture capture and recording tools.

Mediasite.com (by Sonicfoundry) is both a tool for putting recorded "navigable" lectures online, as well as a directory of lectures that can be viewed from the Mediasite webpage. Like all of the other tools listed here, as well as Box Populi, they offer both a hardware box and software to manage the lecture capture and upload.

Others who offer similar tool are (descriptions of each are copied from their websites):

Anystream's Apreso - Apreso Podcast software can be affordably, and unobtrusively, installed on existing podium computers in any classroom where lectures are to be captured. This "capture station" automatically interacts with classroom audio sources to record the professor's remarks. It encodes the lecture audio into a podcasting-ready MP3 version of the classroom experience, called an "Apreso," which can then be accessed on-demand from iTunes or other portals, and synchronized to iPods for later replay.

Accordent.com's Capture Station - Offered as a fully integrated system, the Accordent Capture Station seamlessly records and synchronizes audio, video and data output from any presentation device (notebook PC, document camera, smart board, etc.) and instantly turns it into an online rich media presentation. Version 2.0 gives administrators the ability to remotely provision resources such as classrooms and encoders as well as automatically stop and start the presentation capture process from a centralized location with Accordent's Event Scheduling & Notification module.

There may have been a few others, but I can't remember them all after three days of higher ed IT overload. I would be happy to add others to this post if anyone lets me know about them.
