Classroom Lecture-Capture Technology – Characteristics and Costs

Page history last edited by S. Landau, PM 16 years, 1 month ago
 
Perhaps the most important and probably most difficult aspect of making lecture capture projects successful is getting as many faculty members involved as possible. One thing that can make the buy-in a little more palatable for faculty is simplifying the technical aspects. What follows are descriptions of lecture-capture techniques that we [at Queensborough Community College] have tried to varying degrees of success.
 
 

iPod with Microphone (Audio only)

 
Some iPods can record your voice if you connect a microphone to the docking port (not the Shuffle, and not the most recent generation). A really effective microphone is made by Belkin called TuneTalk.
 
Pros:
  • Really simple to use/record – wear it in a breast pocket or on an armband while you teach
  • Produces high quality recordings in .WAV format
  • Relatively inexpensive – (~$250)
  • iPod nano 2nd Gen (~$180)
  • Belkin Microphone (~$70)
 
Cons:
  • Recordings are limited to the length of iPod battery life with microphone attached – usually about an hour
  • The Belkin only works with the 4th gen iPod Video and 2nd Gen iPod-nano (last year’s models)
  • Captures voice only – however, after class audio can be synchronized with images, PowerPoint slides, etc. using a product like Camtasia (an additional ~$200)
  • No automation – file transfers, output file creation, XML file must all be done manually
 

Marantz PMD660 Digital Recorder

+ wireless microphone (Audio only)
Pros:
  • Easy to Use
  • Very high quality recordings
  • Uses inexpensive Flash Memory – larger means more hours of recording
  • If an outlet is not available it can operate for 4 hrs on 4-AA batteries
  • Built-in condenser mic – but a wired or wireless mic will produce much better results
  • Has Two XLR mic connections with +48v phantom power
  • Built-in USB port for transferring recordings to your computer or just move the memory card to the computer if it has a reader
 
Cons:
  • Expensive (~$700)
    • Marantz PMD660 (~$500) +
    • Flash Memory Card (2GB ~$30) +
    • Wireless Lavalier Microphone (~$200)
  • Captures voice only – however, after class audio can be synchronized with images, PowerPoint slides, etc. using a product like Camtasia (an additional ~$200)
  • No automation – file transfers, output file creation, XML file must all be done manually
 
 

Bluetooth Microphone with Camtasia

 
Pros:
  • Records both audio and images, PowerPoint slides, etc. -  fully synchronized
  • Audio Quality OK but not great
 
Cons:
  • Can be tricky to set up and use
  • Moderately expensive (~$400)
  • Camtasia Studio (~$200)
  • Bluetooth Microphone (~$170)
  • Bluetooth Receiver (~$30)
  • No automation – file transfers, output file creation, XML file must all be done manually
 
 

Mediasite

Pros:
  • Broadcasts Live on the Internet
  • Records both video, audio, and images, PowerPoint slides, etc. - fully synchronized
  • Maintains archived recordings – you need a Windows Media streaming server - automatically
  • Provides a full user interface for accessing archived recordings
  • Rack mount and portable versions exist
 
Cons:
  • Very Expensive (~$18,000 installed + yearly maintenance + Windows Streaming Server)
  • Doesn’t scale easily to multiple simultaneous classrooms
  • Windows Media format only – you will have to convert manually for iTunesU
  • Very limited editing of recordings
  • Tricky to get working for live broadcast  – mostly network issues
 
 
 

Echo360

(formerly Apreso Anystream + Lectopia) - http://www.echo360.com/
 
 
Pros:
  • Scalable
  • Capture can be fully automated (scheduled) if you wish, or partly automated
  • Multiple output formats - H.264 raw video format
 
Cons:
  • Expensive
    • For the hardware version you need a server, a capture license & a capture appliance - plus the multimedia equipment in the classroom – computer, projector, etc)
    • For the software version you need a server, a capture license (~$1,500 per year per room) - plus the multimedia equipment in the classroom – computer, projector, etc)
      • Echo360 capture license (~$2,250 per room per year)
      • Hardware capture appliance (~$2000 per room)
      • Installation (~$1,000)
      • Server Hardware (~$2,000-$5,000)
  • Limited editing – removal of contents only – cannot add
