I’ve been tinkering with video podcasts the past few weeks. My goal is to use the podcast so students can review:
- notes from the past week
- the practice problems at their own pace
- demonstrations and lab activities performed in class
I started off by writing out my notes with GE’s Imagination Cubed
and then did a screen capture with Windows Media Encoder
. It works but the video of the Imagination Cubed came out choppy and the Windows Media Encoder does not give you many options when outputting the video.I really wanted the video to be available as a Flash video
— similar to what YouTube
does. The best video converter I found for this job was the free version of Riva FLV Encoder
. It was easy to use, provided many options and converted the files quickly. If you have several videos to convert, you make want to download the trial of Riva Producer
. It does batch converting and allows you to edit your videos in a timeline.
To play the videos, I chose the Flash Video Player. This free player is easy to configure if you read the directions. I had one snag with the slider but I solved this by using the proper metatags in my flv files. To fix the metatags I used FLV MetaData Injector. Again, this was explained in the installation directions. To host Flash video at your site, you’ll also need to update your webserver’s MIME types to include the flv extension.
The best piece of software I encountered on this trek was Camtasia. It is not a free program but they do offer a fully functional trial version for 30 days. Camtasia is primarily a screen capture program (used to produce screencasts) but I found it does so much more.
Here are just a few highlights:
- edit and trim your video
- add zooms, pans and transitions
- add a second audio track
- insert captions and overlays
- export to a wide variety of formats
Camtasia was easy to use and provided timeline style editing. After I finished editing the video, I was able to produce a Flash version and an iPod friendly version in just one step.
There is something weird about seeing your lesson on an iPod. What’s even weirder is seeing students use it!
The last step to any podcasting adventure is the most crucial—create the rss feed. Your media can not be called a podcast without it. The rss feed is a text file that contains specific information about your show and describes each episode. You update the feed each time you create a new episode. I used several templates as an example to make my feed. (examples: 1, 2, 3) If you want to be iTunes friendly, you’ll need to follow some of their special formatting rules. You’ll also want submit your feed to Apple so users can search for your podcast right inside iTunes.
Here is my final product. I welcome feedback, questions and comments.
