Club Logo

The club logo has been approved by vote of the club members at the September meeting. The new logo will start to show up on various club literature, like the club business card and so forth. If you need a copy of the image or have an idea how we should use it…please let me know.


HDV in your Future?

The club is now up to two members with HDV capable camcorders.  There are  a host of challenges to shooting HD and perhaps  we’ll have a chance to learn from our fellow club members.


If you’ve been following the discussions of HDV camcorders then you might have seen a recommendation to use special HDV MiniDV tapes when shooting in HD. The key claim is that the HDV-rated tapes are less prone to dropouts, those momentary ‘loss of signal’ events that cause an interruption in the recording process.  The interruption is usually just one frame…so you might be forgiven for thinking “no big deal.” But it turns out to be a big deal due to the way HDV is recorded on tape.


SD video recording is similar to film recording---both record a series of individual frames in a sequence, essentially thirty frames per second for Digital Video, and 24 frames per second with film. SD differs from film in that it compresses each picture (losing some information) and it stores each frame in two fields. So with SD footage on a miniDV tape, a  dropout will cause a frame (or two fields) to be lost, and the ‘jump’ is visible, but the very next frame’s information is there and the ‘glitch’ is relatively minor.

The HDV recording does not store each individual frame. To save space HDV stores a “key” frame, and then for the next few frames it only stores the ‘changes’ relative to the key frame. Then the camera captures another key frame, and carries on with this process as you shoot. The name for this “Key Frame + subsequent frames with the changes” is called a Group of Pictures (GOP). This recording process is the same used on your DVDs, called MPEG-2 video codec.


So when a drop out occurs with HDV footage, the very next frame does not have all the information needed to build the picture that you wanted to show. Until the next key frame comes along your video signal will be scrambled and you could lose an important shot.

Camcorder Technique Workshop for November

Originally, we had thought about an editing workshop in November…but with some feedback from others, Dave and I have re-visited and revised that idea.


We’ve assembled a list of exercises that will help novice camcorder users learn how to use their camcorders better---and for more skilled shooters, it will be a chance to test their knowledge and skills.


We have to set a date and location, but it likely will be mid-November (14th to 16th) so charge up your batteries and get ready to have some fun.
