Class Videos and Copyright

The University of California at Los Angeles has stopped allowing faculty members to post copyrighted videos on their course Web sites after the Association for Information and Media Equipment (AIME), a group that protects the copyrights of education media companies, charged the university with violating copyright laws by posting the videos to the password-protected course Web pages without the proper permissions. For additional details, check out the Inside Higher Ed article at http://www.insidehighered.com/news/2010/01/26/copyright (be sure to check the very intriquing comments to the article at http://www.insidehighered.com/news/2010/01/26/copyright#Comments ).

A follow-up article is also available at http://www.insidehighered.com/news/2010/02/04/copyrightredux .

What does this mean? In overly simplistic terms:
  • Fair use only allows a portion of a work (video or otherwise) to be used by a not-for-profit educational institution in the classroom.
  • The TEACH Act extends the classroom to include any online, password protected course space with access only by currently enrolled students, and access enabled only for a time period appropriate to presentation and discussion of the work.
  • The use of the video must be related to specific course objectives (i.e., not just as a time filler).
  • As a "general rule", the TEACH Act would only authorize portions of, not entire works. The exception might include showing an entire film in a media studies program, but other criteria must also be met.
  • The work (including video) must be legally obtained (e.g., not a pirated copy).
  • The Digital Millennium Copyright Act (DMCA) makes it illegal (even if fair use might otherwise apply) to bypass the encryption on digital media (e.g., CSS encryption codes on region-encoded DVDs) in order to create a streaming media version. For example, if you digitize and bypass the encryption on a DVD to create a streaming video clip, the issue of fair use is moot.
  • The TEACH Act does not extend fair use to works primarily produced or marketed for in-class use in the digital distance education market.
JCCC has licenses with several companies to provide video access for instructional purposes, including Ambrosia Video, Journal of Chemical Education (ACS) demonstrations, American History in Video (streaming video collection includes newsreels from 1929 through the 1960s plus hours of documentaries from the History Channel and more), Counseling and Therapy in Video, Dallas TeleLearning Digital Resource Repository, and the INTELECOM Online Resources Network.

Members of AIME, the group that has threatened UCLA with a copyright infringement suit) are listed online ( http://www.aime.org/corporate-directory.php ).

Telling Your Story with Video & Your Video Camera

Yesterday, Bob Epp, Sr. Analyst (Johnson County Community College, Educational Technology Center), presented a Technology Brown Bag on "Telling Your Story with Video." Bob shared his experiences as an attendee at the Travel Channel Academy's 4-day boot camp led by Michael Rosenblum.

Bob discussed the required steps and planning required to effectively communicate a concept in a video format. He briefly touched on storyboarding, script writing and pre-planning for a video shoot, as a brief summary of the 4-day boot camp.

His presentation reminded me of a recent discussion on the New Media Consortium (NMC) list in response to the question: "How good of a camera do you need to videotape for web delivery? Should you still get as good a camera as you can afford or are the cheaper consumer cameras all you need?"

Here are the points I gleaned from the postings (slightly edited).

  • As long as your video image size on the web is something on the order of 320 x 240 pixels, you'll do fine even with old non-high definition (HD) cameras, and certainly with a moderately good consumer HD camera. (Hertz)
  • The little FlipVideo cameras are good for talking head interviews and field news. Actually, I just sent in a video from home that was aired on the local TV news (using) my FlipVideo. The FlipVideo is good for that and for moving around outside. Good because you can quickly upload to YouTube, without needing that much video knowledge. In my opinion, that is the best use of the cheaper consumer cameras: field use. (Laur)
  • In a classroom setting using a FlipVideo or similar camera with no external mic might not provide the quality you need. Recording location and target destination (YouTube, iTunes U, streaming video server) are all considerations. When our target is iTunes U, we use a wireless mic with a digital video camcorder on a tripod. Most of our classrooms are large with people making noise and moving around. You do not notice it until you actually try to record a class lecture and edit the resulting video. (Laur)
  • If you plan to do a lot of editing, you'd be best served by something a little more traditional in terms of a camcorder. A FlipVideo and its peers create video files that are designed to be delivered as-is for the most part. They aren't suitable for frame accurate editing. Scrubbing through these types of files can be an exercise in patience even on a nicely equipped machine. (Saunders)
  • If you use a cheap consumer camera in a big classroom with students coughing and shuffling around, you are going to have audio problems.” (Laur)
  • Your “videographer’s kit” should include a good quality video camcorder, a wireless mic, an equipment bag, tripod, backup hard drive, and editing software. I would suggest (a camcorder) that allows for external mics and either uses a miniDV tape or solid state built-in memory with sufficient storage to record a complete class without needing a recharge or swap power or storage mid-way through. (Laur)
  • Good audio can make not so great video look better. Good audio also compresses better, and delivers content more effectively. (Hertz)
  • Good quality audio quality may require one of the better cameras. An external mic or various mics fed through a mixer (mic for lecturer, mic for audience) can really improve quality of the recording. A camera with good mic/line audio inputs is essential. If you can get a balanced audio input on the camera, even better, but consumer models tend to have just a simple mini-plug input. (Hertz)
  • If you are not working with a good camcorder and a tripod then the best bet might be to only record audio and then use something to capture the presentation on the computer (Camtasia Studio or other screen capture tools). For instance, a chemistry class is best recorded with only audio with a PowerPoint slideshow synchronized with the audio. (Laur)
  • You need to determine what value is added by including video over just using an audio recording. Video adds extra editing time and extra download time. If video is mostly someone talking in front of a class, then the audio plus photos, the so-called enhanced podcast, might work pretty good. (Laur)
  • If you do get a solid state camera, consider getting one that records in the MJPEG format instead of .mp4 or .wmv. I'd personally recommend a better quality SD DV camera that accommodates the audio concerns others are addressing. That way you get a tape backup, which is a good place to store the video long term (those FlipVideo HD files pile up quickly on your hard drive), you get frame accurate editing that performs well on even a moderately equipped machine, and you'll still be well above the level of delivery in terms of quality. (Saunders)

Capturing YouTube Video to Your Desktop

From time to time, we receive requests from faculty regarding capturing video from the web (typically YouTube or TeacherTube clips) to their desktop for use in class. The reasons include:
  • Slow web access times
  • Insurance that the video clip will be available for class use and not disappear or be withdrawn
  • The need to extract a segment and not use the entire video.

There are many tools available to capture video from the web (your students probably know about more tools than you and I ever will) and it’s important to review each use to be sure it complies with educational fair use (use the "Four Factor Analysis"). If the usage is appropriate and does not infringe on copyright, you can go to http://www.techcrunch.com/get-youtube-movie/, enter the URL for the video and click the Get Video button to start the download. The download frequently takes less time than playing the video over the web. Just be sure you save the file using the .flv (Flash video) file extension.

By the way, some YouTube videos, such as President Elect Obama’s weekly addresses, now have a download option (just under the left lower corner of the video image space). It provides access to a H.264 encoded version that can be downloaded and played later offline.

How Small Can You Make a Camcorder?

Digital Camcorders are getting smaller and the prices are dropping. That seems to be the general story of all technology. I’ve recently tested a Flip Video Ultra camcorder (see http://www.theflip.com/products.shtml) and found it wonderfully small (fits in a shirt pocket). It’s lightweight too. It records video on internal memory rather than on a miniDV tape. The Flip Video Ultra can record 60 minutes of video using 2GB of internal memory (the Ultra has 2GB while the regular Flip Video has 1GB). Note, the newest addition to the Flip Video family is a 2GB Flip Mino. It’s much like the Ultra except it includes an internal Lithium-Ion rechargeable battery capable of 4 hours recording between charges. It retails for $179.99.

I was pretty impressed with the 640x480 resolution image from the $149 camera, until I ran across the AIPTEK A-HD 720P digital camcorder (see http://www.aiptek.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=R-AHDB&Category_Code=DC1&Store_Code=AS) which retails at $159.99 (as low as $139.99 refurbished). While the A-HD 720P doesn’t have a snappy name (like Flip Video Ultra), it does provide high definition (HD) video recording (1280x720 using H.264 video compression) and is also an 8 megapixel still image camera and media player all rolled into one. The video you capture can be played on a high definition TV, standard TV, PC or Mac (cables are included) and enables you to record direct from a TV set as well. Some of the other significant differences include a rechargeable 1000mA Li-ion battery good for about 4 hours of recording (the Flip Video Ultra uses 2 AA batteries that give you approximately 2 hours of recording time) and the ability to use up to an 8GB SD card (the Flip Video Ultra’s memory is not expandable). The bad news is that the A-HD 720P does not come with an SD memory card, so you must buy one or you don’t have sufficient memory to record video (it comes with only 6MB internal memory). So effectively, the cost of the camcorder is $12 to $30 more than it seems. The following chart indicates how much video recording time or how many images you can store based on the SD card size and the resolution of the images/video you capture.


One negative to the A-HD 720P is it’s a bit heavier than the 5.2 oz Flip Video Ultra (can’t find an exact weight in the specs).

The A-HD video files are compressed (stored in the QuickTime .MOV format using H.264 video compression) while the Flip Video Ultra uses Pure Digital Video Engine 2.5 to compress in .AVI format. With both camcorders, it takes some practice to steady the camera and adjust the zoom (both units employ a 2x digital zoom).

Prices listed above are list and can be “beat” at http://www.amazon.com/ and other vendors. There are accessories available for both camcorders (tripods, and so on). Either choice is a giant step forward in miniaturization and price reduction.
