Get the Fat Out
I was reading your December 2005 Tech Support column and noticed that you failed to correct for DV's aspect ratio when extracting a still. With your instructions, objects in the still will look slightly "fat" due to the incorrect aspect ratio. To correct this, simply crop the frame to 704x480 and then resize to 640x480 before you do anything else to the still. This will convert the 720x480 frame to square pixels which can then be processed however you like.

Thank you for the additional information, Scott. We received a couple of letters from other sharp-eyed readers like you with similar comments about pixel aspect ratio. We hope Scott's reply will clear up those questions.

Cable Coiling Conundrum
Managing excessive lengths of cable and cord can be a real hassle. I recently experienced this while cabling up under my wife's computer desk. In a minor stroke of genius, it occurred to me that a perfect cable management tool would be empty CD or DVD spools and covers. First, I hot-knifed an inverted U-shaped access hole in the side of the cover. Next, I drilled a small pilot hole on the base of the spool. I then screwed the base of the spool onto the back board under the desk. All that is left to do is gather up the excess cord, coil it around the hub and twist lock the spool cover in place. Simple, elegant, and a great way to recycle empty DVD spools!

Unsung Heroes: Camcorder Support Systems
The stars of video production equipment are not tripods, dollies or jibs. That's not their role. They are meant to blend into the background, be sturdy and dependable and never have tantrums on set. Of course, they may be typecast into supporting roles, but replace that sturdy, fluid and dependable friend with a loose lackey, and all of a sudden, everything else doesn't seem to matter.
