Improve your video audio by turning off AC/DC power

In my Audio & Video learning over the years, I discovered this little nugget to improve audio quality when recording video.  I’ve only recently remembered to create a video on it.

Here is my setup:  Sony HDR-SR11 HD video camera with a 1/8 microphone input, an unbalanced lapel microphone with a 1/8 mono connector, & the AC/DC power cable for the camera.  This is a general problem with unbalanced microphones and when transformers are in close proximity.  Take a listen to the video to see the improvement in action.

Searching for My Destiny

I received a email this morning from one of the email lists I maintain.  In it was a upcoming event of great interest to me personally because I knew this person’s family was from Paguate Village in Laguna Pueblo.

The email was about Dr Blue Spruce, Jr from Roxane Spruce Bly.  I was only aware of the family growing up in Paguate and was very surprised to learn more about this individual.

The email read:

Recognized as the first American Indian Dentist, Dr. Blue Spruce, Jr. founded the Society of American Indian Dentists and is currently an Assistant Dean at the Arizona School of Dentistry and Oral Health where he has motivated many Native students to attend dental school and return to their tribal communities to practice.

His recently published autobiography, Searching for My Destiny recounts his childhood growing up at the Santa Fe Indian School and his parents’ determination that their children obtain college degrees.  He describes the loneliness and challenges of leaving home and graduating from dental school at Creighton University as well as the excitement of a career that took him from Montana to New York City and South America.

Please join Dr. Blue Spruce Jr., his family, and friends to honor his contributions to Indian health and hear his personal memories of traveling between two cultures, facing prejudice, and conquering adversity to achieve the rank of Assistant Surgeon General of the United States.

Light refreshments will be served.

When:  Saturday, June 26, 2010 at 3pm
Where:  Indian Pueblo Cultural Center
2401 12th St. NW
Albuquerque, NM  87104

After reading this, I went about to find out what else more was on the internet, and here is what I uncovered for all the readers of my post here.

Here is the audio from the NPR event, the book review & interview start at about the 6 minute mark:

I have not read the book yet (it’s now on my list), but I’m sure there are some similarities in our paths dealing with mainstream culture vs native culture and learning away from home.  I’m really looking forward to the event honoring Dr Blue Spruce, Jr at the Indian Pueblo Cultural Center.  I’m sure there is plenty to learn from his journey.

San Juan River Fly Box

I really love fishing the San Juan River in New Mexico, it’s one of my favorite places to fish because one can get into 20+ inch trout in the quality waters just below Navajo Dam.  The consistent flows and consistent water temperature create a rich food source for all the trout that live there.  It’s this rich food source that causes the trout to feed on very small bugs, and when fish feed on very small bugs you need very small flies.  In this video I detail my San Juan River Fly Box, what it is, how I made it, and how I use it.  Enjoy!

700 MHz Wireless Microphones

The FCC recently reminded people (on 5/28) in the United States that there has been a change in spectrum allocation to avoid interference.  On June 12, 2010, wireless microphones and monitors will no longer be able to be used in the 700 MHz band (specifically698 to 806 MHz).  Here is the PDF on the FCC website.

What this means, is those individuals/groups who use wireless microphones for audio capture for video, screencapture, or podcasting, in the above bandwidth will start to receive noise and non-ideal audio as new 4G consumer devices are deployed in proximity to the wireless microphone.

The solution for the vodcasters/screencasters/podcasters is to either replace the wireless microphone or work with the equipment manufacturer to get the wireless radio inside the transmitter & receiver changed out to operate on a frequency outside the 700 MHz band.  Some manufacturers have a trade-in or rebate programs to help people with this change.

Here is another helpful link on the FCC website which lists known wireless microphones in the 700 MHz band.

Now, if by chance you live on a Indian reservation away from any mobile or cellular phone service, your wireless microphone should work just fine after June 12, 2010.  🙂
