how can I measure the quality of a camcorder? mega pixels or 1080p?

Q. what does 1080p stands for? and why there are camcorders that say HD 1080p with 3.2mp? what does the mega pixels mean at this point? ps: I'm totally new in movie making.

A. 1080p means the image is high quality because each frame is made up of 1,080 tiny lines, one on top of the other (imagine drawing 1,080 lines accross a page of paper from top to bottom). Normal television images are made up of 575 lines (USA) or 625 lines (UK).
The 3.2 megapixels probably refers to the amount of dots used to make up the still image when taking a photo with the camera, ie- 3.2 million dots. To give you an idea, most modern mobile phones can take a picture with that detail, a decent digital stills camera these days uses 10 megapixels. However, the quality of the still imaging does not really relate to the quality of the video image. A HD 1080p video image should be excellent.


What flash based camcroder should I pick up?
Q. I'm heading to D.C. next month and I wanted a camcorder to record the whole trip. It will also be used to capture a podcast, that to this point has been audio only. My requirements:

Linux Compatible
HD (1080p)
Under 200$ more towards 100$
(optional) LANC jack, so I can plug in an external microphone

A couple of years ago this would have been impossible, now I think it might be do-able. Thanks for the answers!

A. LANC is not a mic input. LANC is a wired remote control for zoom, focus, photo and power.
http://en.wikipedia.org/wiki/LANC

The least expensive camcorder with a LANC port is the Sony HDR-HC9. It also has a 1/8" (3.5mm) stereo mic jack and manual audio control. It is a miniDV tape based camcorder that does 1080i HDV format high definition digital video capture.

1080p camcorder's in your price range are typically "pocket camcorders" with small lenses and small single imaging chip. The resulting low-light behavior is typically not very good. Generally speaking, they record to either AVI or MOV highly compressed h.264 formats. Whether this is "Linux compatible" is sort of important - but what matters more is if the video editor you are using can deal with the video format. I am not aware of any camcorder in the "pocket cam" range with a mic jack (and most certainly none have a LANC port) - but you can check the Sanyo Xacti lineup or the Kodak Zi8. Even if they have a 1/8" mic jack, they do not have manual audio gain control so loud audio will likely cause a very muddy audio (and static - "peaking") to be recorded because of the dependency on the auto-mic gain circuit.
