what does progressive mode do?

hello. so I just got my dvx not to long ago. Any I know what 24p, 24pa, and 30i and all that does. But what does progressive do? I tried a search but got more questions than answers.
 
From Panasonic's FAQ page:

14. Does the AG-DVX100 avoid edge tearing (interlace combing) artifacts on moving objects?

Yes. The CCD based imagers used on the AG-DVX100 are progressive scan devices, which means the images they capture are much more like a sequence of still photographs than a traditional video signal. As you know, a still photograph NEVER suffers from edge tearing - which in the video domain is called combing and is caused as a byproduct of interlace based scanning - instead, fast moving edges blur out, whereas slow moving edges are well defined. A cinematographic film camera of course normally exposes a sequence of still frames at a rate of 24fps, in order to provide the illusion of continuous motion, and this is the process emulated by the AG-DVX100 when in 24p mode.
 
whoops...I think I meant to ask what it does when its turned off....cuz I accidently shot two scenes with it off, so I just hope that is not bad.
 
Then you shot interlaced video. It's definitely gonna have a different look. Is reshooting an option?
 
er.. I can prolly reshoot some of it. I hate how I put it into 24p mode and then turn the camera off for a minute and progressive switches back to off when I turn it back on. That got me a couple of times.
 
You need to scroll all the way to the bottom of the scene file menu and save it if you want it to remember your settings when you turn the camera back on.
 
SAVE YOUR SCENE FILES!

Nobody ever does this, but everyone should. If you don't save your scene files, all the changes you made will be lost, and the exact circumstance you encountered (footage not matching) will happen.

Whenever you change your scene files, save 'em. It only takes a second and it prevents a lot of potential hassle.
 
Yes! For example before shooting a project I will do lighting tests at all the locations (the ones I can use before the shoot anyway - some wont let me sometimes) or in as similar a location as possible. Usually I take just about anyone on these to stand where I need them. All my six scene files are saved at different locations (sometimes too many so I note those most similar for later). I end up with six scene files that are all set to 24pa and are set to a location. Obviously some things can vary - like ambient light etc. So after trying to kill the difference as much as possible a few small tweeks and Im there.
 
I make a point to save my scene file settings before an important shoot. That saves time on having to adjust the settings again after the cam has been turned off & back on again.
 
I also white balance properly when in a new environment & assign it to either preset A, or B. Since I shoot mainly weddings at hotels, I assign my indoor whitebalance to B (B-for Ballroom) & any other location shots to A.

But I wish the DVX had more than 2 settings (A & B) to save my whitebalance. Like C or D or even more since the whitebalance settings can't be saved in-camera like saving scene files settings.

I find this to be limiting esp when I need to white balance 3 to 4 different locations. Because of this, I have to regularly white balance.

Any suggestions? Thanks.
