Why underscan on CRTs, LCDs, and the DVX100?

I guess they felt that if they showed the whole image, a lot of beginning filmmakers who don't know about the whole "underscan/overscan" issue will frame to the LCD/EVF, not knowing that on a regular TV, whatever they put on the edges won't be shown. Of course the downside of doing this is that you might frame to the LCD/EVF and when you show your film on something that doesn't have overscan, like a front projector, then you'll see things on the edges that you didn't know were there, for instance a boom mike. The best thing Panasonic could have done is give us the option to switch between under and overscaned images or show us the entire image and put a lined box on the screen indicating where the overscan would occur on a TV like how studio cameras do. But I guess Panasonic didn't want to confuse people who wouldn't understand and as a company, it's always safer to play to the lowest common denominator.
 
For the same reason that the PD170, PD150, XL2, XL1, VX2000 and basically every camera prior to the 100B did, which is basically the answer that EA_Cru_2002 gave. The overscanning in the LCD & viewfinder is probably meant to match the overscanning being done on televisions.

At least the 100B changed that and gave us full-screen viewing.
 
100a monitor question

100a monitor question

hey barry!

i bought your book dvd package from amazon, and i have to say , its the best of the best ....EVERYONE should have it.

my question is a simple one:

if we use an on-set or on-camera 16:9 monitor , will we see underscan from the camera>

are there any workarounds besides the B model?

( we bought our A 2 weeks ago!!!!!!!!!!):laugh:
 
Underscan is a function of the monitor independent of the camera itself. If your external monitor has the ability to do underscan (some don't) then you will get the full image.
 
undersca overscan

undersca overscan

Sorry for maybe not understanding but I own a 100b, what I see on the lcd does it contain what is outside of the safe zone on a studio cam or not?

Thanks guys

huh, interesting.

so I take it the HVX will follow along with the 100b? Will it be an option to switch between the overscan and underscan on the LCD?

seriously. :o
 
I think it has (had) something to do with real estate on the smaller LCD screens too.

The Z1U "Allscan" mode gives you the underscan shot, but man... there's a lot of dead real estate around that raster. I get squinty looking at it.

Yes it contains what is outside the safe zone. It shows you the full frame, like a studio cam does.

Sort of -- there's a "safe zone" overlay you can switch on. The LCD doesn't do overscan/underscan resizing; it always displays the full frame, but you can choose to display the safe zone markers to keep track of the safe zone.
 
Yes. This was a change added to the 100B. The 100 and 100A act like basically every other camera on the market, only displaying the overscan "safe zone", not the full frame. The 100B changes that by displaying the full frame.
