Do It Yourself Tripod for your iPad

  Next week, I will be visiting with a teacher who wants to shoot classroom video using her iPad.  Now, the iPad makes a pretty good video camera, shooting in 1080 resolution with the entire screen as your "viewfinder".  The only problem is that the stock iPad won't fit on a tripod, so somebody has to hold the darned thing while it's recording. 

  Our friends at have all sorts of iPad tripod mounts for sale, starting at $7.99 and going up from there.  Very good if you have a few dollars to spend and a week to wait for it to arrive from the warehouse.  What if you want a quick and free solution? 

  Mivil DeschĂȘnes has produced a short video showing you how to turn a cardboard box into a functional iPad tripod.  Take a look!

From the t.i.c.l. Conference 2014

  Here is the PowerPoint presentation that I used at the 2014 t.i.c.l. Conference at Buena Vista University.  The previous post has links for both training videos mentioned in the PowerPoint.

Make it so!

  It seemed so simple during the planning sessions.  Teachers would shoot video in their classrooms, upload the video clips to the web and then our PLAEA consultants would review the video clips.  As long as the teachers have access to a smart phone or an iPad, it should be easy as pie.  Shoot, upload and view.

  That was our plan.  Now, as Captain Jean-Luc Picard used to say, "Make it so!"

  Then we started getting phone calls and emails from the teachers who were attempting this feat.  The videos they shot were taking forever to upload, sometimes several hours.  Sometimes, the website would "time out" and the entire process would come to a screeching halt.  What is the problem here?

  After some investigation, we discovered that the file sizes of those video clips were just too darned big.  For example, an iPad shoots video in high definition, so even a 20 minute video clip is nearly 3 gig in size.  That's right, 3 gigabytes for 20 minutes.  How can you shoot a 50 minute classroom presentation and then upload it to your Dropbox account that has a maximum capacity of 2 gig?

 My suggestion was to use video conversion software to convert the video clips to a more compressed format.  Using video conversion software also lets the user downsize the resolution from HD to SD.  Changing the format and downsizing the resolution will shrink the size of the video file, sometimes dramatically. That 3 gig video clip became a 725 meg clip after conversion and downsizing.  That's small enough to easily fit in your Dropbox or Google Drive account.

 Different cameras and computers require different software to achieve this file compression.  So I'm producing videos to address that.

  What if you are using a Flip camera and transferring that video to your Windows 7 computer?  I suggested our team use Any Video Converter.  That's freeware that is available from CNET.  Then I recommended the converted clip be uploaded to a Google Drive account.

 Here is the video I created to explain the process. 

 If you are using an iPad, then it's even easier because it can all be done with your iPad.  Two apps, GDrive and Video Slimmer, allow you to compress your video clip and then upload it to your Google Drive.

 Again, I produced a video to demonstrate the process.

  That's not all of the camera and computer combinations out there.  But these two procedures and the accompanying instructional videos should help our classroom videographers to successfully shoot and upload their projects.  As additional instructors contact us, I'll search for solutions that apply to their specific hardware and computer operating systems.

Sound Advice

Combo headphone-mic headset

  Video conferencing is amazing.  The idea that we can turn a meeting room into a makeshift television studio and broadcast to the world is astounding, even to a veteran media person like me.  In order to have a successful broadcast, we need to use the right tool for the job. 

  When we’re dealing with video conferencing, we are broadcasting two things: picture and sound.  And while everyone understands that the video camera needs to show what the viewer wants to see, it can be a challenge to have the microphone pick up what everyone wants to hear.  

  Audio rarely receives the attention it deserves, even though so much of the information conveyed during a video conference is actually heard rather than seen.

So, what tools do we use to gather sound?  The microphone that is built in to your laptop does a pretty good job if you are the only person on your end of the conference.  However, using the built in mic and speaker can often set up a feedback or echo effect, where your mic hears and rebroadcasts the output of your speaker.  You will avoid that problem by using a combo headphone-mic headset like the one pictured. 
Blue Snowball mic

  If you have a group of people gathered around a table, you need a different kind of microphone to hear everyone clearly.  The Blue Snowball microphone can be switched from a cardioid pattern to an omnidirectional pattern, which means it can be used by a single person or set in the middle of a table to pick up an entire group of people.  It connects via a USB cable to your computer and is compatible with Skype and other conferencing software.

  Another style of microphone that is well suited to gathering sound at a meeting is the PZM or boundary microphone.  It sits flat on the table and picks up reflected sound.  This is the style of mic used with a Polycom and AVer video conferencing system.  Some models, such as the MXL-404 (pictured) also connect to your computer via USB.

  My father always told me to use the right tool for the job.  So use the right microphone for your next video conference. Your audience will appreciate being able to hear you better, and that’s sound advice.

Tech Friday Presentation on Basic Editing

This Friday will be the first Tech Friday at Prairie Lakes AEA.  It's an opportunity for staffers to receive training on various types of technology available to them.  I will be talking about basic video shooting and editing using Windows Movie Maker.  While it is not my favorite editing package, it is available on all staff laptops here at the agency.  It's here, it's let's use it.

I'm embedding the PowerPoint I will be using so it will be available to attendees and anyone else who may get some mileage out of it.  I'm sure you'll find better tutorials out there, but this is the one I'll use to begin our conversations about media production.

NEW FCC Rules on Closed Captioning for Web TV Content

An article seen on advises us that "Web TV needs to have captions starting next month, FCC rules".  This was established with the "Twenty-First Century Communications and Video Accessibility Act of 2010" and reaffirmed by an FCC ruling just a few days ago.

Does this apply to you?  Are you legally required to CC all content you upload to your YouTube or Eduvision website?

First off, a caveat:  I'm not a lawyer and I don't play one on TV.  For legal advice, always consult your attorney.  All right, moving on.  From my reading,  it appears that this applies to programming that has been shown on television and does not apply to "web-only" content.  If you are producing content in your home studio or school media center, this law does not legally require you to add Closed Captioned content to your video projects that you upload and show online.  That's my take on it, anyway.

  However, this does not answer if you should provide CC or subtitles on your video projects.  Does it serve your audience to have this content available to the hearing impaired?  Is it a good idea even if it's not legally required?  That is something you need to consider with your current and future video projects.

School announcements on video...No Money? No Problem!

Here is the PowerPoint presentation I gave at Buena Vista University in June that outlines ways to produce your school morning announcements on video without breaking the budget.

I only have one rule: DON'T do this to your data projector!

My supervisor brought her Proxima data projector to me today. The picture is very dim, she said, and could I take a look at it? So I took her projector to the test bench to see if I could discover the problem.


The first thing I did was open the little access panel on the projector and remove the bulb. What the heck was wrong with it? As you can see in the photo, the heat-absorbing glass in front of the bulb was melted and fractured. So then I looked at the lens cap and saw that it had begun to melt. So riddle me this....what would cause the glass panel on the front of the bulb as well as the lens cap to melt?

Right. Someone had powered up the projector and then placed the lens cap over the lens. All of that high intensity light was shooting out of the bulb, hitting the lens cap and reflecting back into the bulb housing. That creates a tremendous amount of heat; enough to melt a quarter inch thick piece of glass that is specially designed to absorb heat.


Normally, this would mean buying a $120 lamp to replace the one with the melted glass. However, I was fortunate enough to have a burned out lamp of exactly the same make and model. Removing the melted glass from one and replacing it with the intact glass from another allowed me to make the repair for nothing. Just dumb luck that I had not thrown away the bad bulb a week earlier.

As Barney Stinson says on TV, "I only have one rule." And my rule is this: NEVER, NEVER put the lens cap on a data projector while the bulb is lit. You will ruin your expensive bulb and also perhaps your expensive projector.
