Using SlideShare's Slidecast Feature


SlideShare has a feature called Slidecast which allows you to sync up an audio track with your slides that you post on the SlideShare website. When I first heard about this, I thought it was pretty cool, but I didn't really have a need for it. However, lately I've changed my mind. I can do that you know. If you're not familiar with SlideShare:
SlideShare is the best way to share your presentations with the world. Let your ideas reach a broad audience. Share publicly or privately. Add audio to create a webinar.
SlideShare allows you to post your slideshow presentations on the web. Formats accepted are PowerPoint (ppt, pps & pot), PDF, OpenOffice (odp); Keynote users on a Mac can "Save as pdf"; and the max file size is 30 MB.

Initially I wasn't interested in created slidecasts because I don't use a lot of PowerPoint in my classes, and I was starting to create more screencasts for my online lessons. I didn't think there was a need for a slidecast. Then I needed to recreate a podcasting presentation I did for MCLI for faculty on my campus who could not attend. I already had slides uploaded to Slideshare, so I just recorded some audio and uploaded that too to create a slidecast.

I created the audio in the same way I would create a podcast because essentially it is a podcast, hence the name slidecast. I used Audacity. As I read through the slides on one computer, I recorded the audio on another. This can be done all on one computer as well. It just so happens that I had two, so I used them both. Once I was finished recording, I exported the audio as mp3 and uploaded it to my server. SlideShare requires that you host your audio files elsewhere, so you can pay for the bandwidth. Then in Slideshare you just post a link to the audio file. But why should I type out how to do this when you can just watch a slidecast showing you how? Enjoy.
