Our colleague David Wicks from Seattle Pacific University, is a leader in helping develop, dream, and implement relevant teaching and learning using Online tools.  He recently made an incredible screencast of the Blackboard Grade Center and I asked if we could share it.  A gracious collaborator, he accepted.  I think this is one of many amazing resources from SPU and Professor Wicks.

The Workflows

If you’re reading this, you already know there are a myriad of ways you can create workflows for moving content.  I’ve spoken to several other schools that serve content many ways.  Some push the video into an FTP space where students push the files to iTunes U.  Some use other media servers and push the files to the Web.  Some stream.  Some use Woolamaloo to push to iTunes U.  Some use Automator.  Some Podcast Producer.  There’s also the OpenCast project and enterprise YouTube as options.  If you want to spend some more money, Tegrity is a solution we were very impressed with.  TechSmith just released Camtasia Relay which looks promising as well.  Whether it’s fully-automated like Berkley with cameras in classrooms that automatically turn on, record, and post with no interaction of faculty, to full-service models that use tape, workflows are definitely not one size fits all.  But in our business, they are necessary evils.

Putting the Pieces Together

Not only to we have to create workflows, we have to consider the UI for students, experience for faculty to get academic buy-in to get content to students, and make sure that it integrates with whatever back-end systems and infrastructure your campus has.  Oh, then there’s the budget issue.  If you can get the stars to align, you MAY be able to make things work.  Here is what we have set up in the “server room”:

• Active Directory
• Blackboard 7 (upgrading to 9 this summer)
• Vanderbuilt Bb Building Block for iTunes U customized by our software team
• Hosted iTunes U
• Leopard Server with PCP integration
• New Intel iMac lab and one 8-core Mac Pro

#1  Tape to iMovie/FCP to iTunes U

This scenario we import the Mini-DV tape into either iMovie (quick and dirty) or Final Cut Pro.  We create titles in Photoshop, export them as .jpg, and insert them into the timeline.  Either way, we export to m4v and upload the file to iTunes U.

Screencast Example

Classroom Capture from a classroom from our YouTube Channel:

#2:  Podcast Capture

We’ve tried this scenario and tested it with minimal success.  In a controlled enviornment, we’ve hooked up a MacBook via Firewire to the camera rig and hard-wired the MacBook to the network.  Then connected Podcast Capture to the rig, selected a class from an already existing workflow, and recorded using the naitive app.  It worked for recordings less than 5 minutes.  Posted directly to iTunes U.  However, it has not worked in a longer lecture scenario.  The problem with this is if the file doesn’t upload properly, the recording is lost.  We learned this the hard way.  So we always back up everything with tape.  This was mildly successful with speech classes in our COM department for students doing 3-5 minute speeches.  Mildly.  I’ll explain in scenario #3.

#3  Quicktime Pro with PCP

With Podcast Capture not reliable for us at this stage, we tried using the Firewire scenario hooked up to the camera rig (tape backup), and recording directly to QT pro.  This provides a .mov file on the desktop that can be uploaded to PCP.  This gave us a better success rate with short 5 minute speeches.

Uploading Options

We use a variety of uploading options.  None of them reliable.

• Woolamaloo |  Download Mac |  Download PC
  
• Woolamaloo Automator Actions for iTunes U |  Download
  
• Podcast Producer native app
• Podcast Producer Web app [was a free download but apparently Apple bought it and it's not available any longer for free]
• iTunes U Web interface

I’ll spend some time writing later about the iTunes U upload problems we’ve had.  Any of you who use iTunes U are more than welcome and encouraged to share your successes and failures.  So, these are what we’re doing at a high level.  I can provide anyone more details and open our house to all.  We want to partner with anyone who desires to share and provide the best tools for our students to learn.  I’d be remiss if I didn’t give a huge shout-out to Rich Wolf from University of Illinois at Chicago for writing these great apps and providing them free.  Thanks a bunch, Rich.  Keep up the great work.  Now that I’ve provided an overview of our process and workflow, what is yours?  Am I behind, or should I be presenting to you?  Let the conversation begin.

Walking You Through Our Process

This piece is pretty elementary.  but it explains in detail what we use and how we use these pieces to record a classroom lecture or activity.

Pre-Production

Right now we use a full-service model whereby either myself or our student staff will go to a classroom and capture the event.  We use a Web site with a form they fill out or call/email us directly.  We then use a shared calendar in Exchange where we schedule the event, contact the faculty member, and confirm that we’ll be there.  The students then will go to the classroom, record, and post-produce it in our video studios.

Post-Production

They either edit in iMovie ‘08 or Final Cut Pro.  We have several standard titles and slides they use to create custom intros and extros.  With Leopard Server integration and Podcast Producer configured to Active Directory, we are also using it to push video after creating some standard in/out movies for Quartz Composer to render in the workflows.  I’ll speak more to the workflow/uploading process in the next post.  Once the audio/video files are in iTunes U, the student contacts the faculty to let them know.  The faculty then creates a link in the Blackboard course to the media files.  We created video tutorials for faculty to use in order to understand the process as well.  This is still a work in progress.  Our workflow to Blackboard is explained in an earlier post as we were developing the infrastructure.  Feel free to post comments on how your process works.

A Brief Overview

Many schools have asked what gear we use for media capture scenarios at Spring Arbor University.  Knowing every school does media capture differently, we decided to make a three-part video series on what we do for media capture, how we configure the gear, and what workflows we use to migrate content from the classroom to the Web.  We hope this helps get some of you an idea of where you can start.  This is part one of three.  In this tutorial, I show you exactly what contents are in our full-service media capture bag and how we store it.  Part two will demonstrate how we set up the rig in the classroom.  Finally part three will show you a couple of delivery options we use.  Keep in mind this is what we developed on our own and is subject to change.  We’d value lots of feedback on what you do and what’s worked.  Let’s get the comments flowing.

We’re excited to welcome another guest contributor to the community. Daniel Shackelford is a system administrator from Spring Arbor University. He is currently trying to set up and configure Leopard Server and Podcast Producer with some pretty amazing automation. Please welcome and post comments to his posts.

As we integrate Podcast Producer into our media publishing infrastructure it becomes obvious that manually setting up each course for iTunesU publishing could be onerous as our implementation grows.

So, taking a cue from George Cook (from Apple), I modified his pcastgroup script to work for iTunesU.

Note: This article and script are somewhat technical and assumes familiarity with the Podcast Producer infrastructure and technologies.

What it does:

• Creates an OD group for the course, using the course ID (ie. EDU360) for the name.
• Associates the course ID to an iTunesU tab ID (ie. 1234567890.01234567890).
• Adds a podcast admin group to the course group just created (or any group you specify).
• Sets up services for this group (calendar, mailingList, wiki, blog, webCalendar, webMailingListArchive).
• Generates a new workflow from a template.
• Generates the new template files for the workflow (template.plist, info.plist, InfoPlist.strings, multipart.txt.erb).
• Copy the finished workflow package to /Library/PodcastProducer/Workflows.

What it does not do:

• Any sort of verification of the info you throw at it, apart from checking to see if the group exists.
• Update an existing group with the changes listed above.
• Setup the group in a way that makes it available in the Directory app (I am working on this one).
• Create the iTunesU course (you will have to do that ahead of time in order to get the tab ID).
• Add users, grant access, or any user management tasks.
• Work out of the box. *Setup is required. See comments in the script*
• Generate a workflow that does anything but publish to the specified iTunesU course (no blog, etc.).
  

What I would like it to do in the future:

• Work with the Directory app so that the groups can be managed remotely by OD bound workstations. This does not work yet due to my difficulties in getting a plist into an attribute entry in OD. If anyone has some experience with dscl -createpl, I would welcome a little assistance.
• Be scheduled to go through existing AD/LDAP groups in a given OU and create groups and workflows for them and add the AD/LDAP group to the membership so that users in the AD/LDAP group can automatically publish to iTunesU.
• Integrate with Blackboard (or other LMS) so that the existing cross-reference list generated by the building-block we use can also be used to automatically generate the workflow. If this works, the item above would be unneeded. For us this would entail queries to an MS SQL database to get the course and tab IDs, so I am not sure how practical it would be. Might be easier in Ruby than shell.
• Generate a workflow that can publish to other outlets like group blog, wordpress, etc., as an option.

Well, here it is. Let me know what you think, and how it works for you.
