The Flip Video Ultra has been a big hit among faculty, staff, and students who have used it this semester. The video and sound quality are impressive for such a small, easy to operate, uncomplicated device. So far it has been used to record short student presentations, capture video of projects, and to video short student-related events. I promised to write a little something about using the Flip Video Ultra camera for video podcasting, so here’s a brief overview of what to do and what to keep in mind when using it.
Shooting:
- The camera runs on double AA batteries, and video recording uses a lot of power, so buy rechargeables and keep some handy.
- It can record 60 minutes of video clips before it is full (this is the Ultra series only, prior models only record for 30 minutes).
- The Flip software will put your videos into separate clips based on when you start and stop the camera, so use this to your advantage.
- To capture decent audio, make sure the camera is not too far away from speakers.
- Digital zoom can become pixelated, so it’s best to move closer to the subject rather than relying too much on this feature.
- A small, portable, 10″ tripod is available for the Flip for $29 to avoid shaking and moving, and it also can be mounted to almost any other larger tripod.

There is some confusion over AAC and MP3 audio files. AAC is the newer format (popularized by Apple’s adoption of it in its music store) and has many advantages over the older MP3 format, including higher sound quality and smaller file size. The iTunes Music Store supports both AAC and MP3 formats. If you read up on the two, you will see that AAC is slated to replace MP3 as the most widely used format. (FYI: the MP3 extension ends in .mp3 while the AAC extension ends in .m4a)
If you have an older MP3 media player that doesn’t play AAC files but plays MP3 files, no problem! Read the rest of this entry »

This short 90 second clip covers how to use the Griffin iTalk to record audio on your iPod, which you can later convert to podcast ready formats. Use it to capture lectures, record interviews, discussions, forums, guest speakers, etc.

If you are using Audacity and can’t export your project to the MP3 format, you can export it as a WAV file. WAV files are extremely large. This is fine, but if you want to upload that file to iTunes or Blackboard, you will want it to be smaller and compressed, in either AAC (m4a) or MP3 format. Here’s how you can use iTunes to accomplish this:
Convert to AAC (m4a)
- Drag the file to iTunes.
- While the file is highlighted click the Advanced menu at the top.
- Choose Convert Selection to AAC (for MP3 conversion see below)
iTunes makes a duplicate copy of it in the new format. To check the file type (since you now have the original WAV file and an AAC file with the same name, right click your file and choose Get Info. There you will see the file type and be sure you choose the converted one). You can also add information to the track, as well as podcast artwork that you have designed. Drag converted the file out of iTunes to your desktop for easy uploading.
or Convert to MP3
- Follow the directions above using the Advanced menu, but prior to doing so, go to iTunes > Preferences > Advanced > Importing
- There, change the Import Using: AAC to Import Using: MP3 Encoder
- Now when you highlight the track and choose Advanced on the top menu, you will see Convert Selection to MP3 rather than AAC.
Thanks Doug Seidler over at NESAD for pointing this out to me!
