You forgot FUBAR, for those butter finger moments on a boat, tall buildings...

SSE implies it is a desired effect, try

SSF = Split Screen Fault

Justin Deming July 30th, 2006 10:47 AM

Might I add

ROFLMAO (Rolling On Floor Laughing MY $@% Off)
PCB (Pre Constructed Building) - Where I Live
DFAC (Dining Facility) - Where I Eat
OC (Operations Center) - Where I work
HMMWV (Highly Maneuverable Mobile Wheeled Vehicle) - What I Drive

OK, it's not related to video.

Seriously though, thanks for the defenitions, some people like me are overloaded with acronyms. I use to be a computer engineer too, so I have all that stuff inn my brain too! (IDE, SCCI, RAM, ROM, TCP/IP, BITS BYTES, Etc...)

What a complicated world we have created!

Lets not forget...

WTF?!

You figure it out, I like my posting privileges. ;)

My personal favorite
 
Well since I live here out on the west coast in casual California...

NIFOC = naked in front of computer

On a more serious note, I'd LOVE to see a glossary of all the three letter codes used by people involved with film, particularly the camera, lighting, and cinematography folk.

JVC HD200 14 bit A/D?
 
On the new JVC HD200 one of its features states: 14 bit A/D?

Sorry guys what is the A/D referring to here?

Thanks

A/D= Analogue to Digital converter

The light hits the sensor. At each pixel the light generates a voltage (think of a solar cell). This voltage is an analogue measure of the amount of light hitting the sensor.

This voltage is measured by the A/D converting it from an analogue voltage level into a Digital value (eg 1 volt).

The more accurate the A/D process the more accurate the digital value of the original voltage. Generally speaking the more bits the better. Just like with the number of colours in a digital photo (8bit = 256 colours, 16bit = 16million colours).

12bit (HD100 I think) generated a voltage with 4096 possible values
14bit (HD200/250) generates a voltage reading with 16,384 possible values.

As you can see, each bit increase in sampling doubles the resolution. The 2 bit difference is quite significant.

Ois
 
On another thread Steve Mullin referred to "OIS" as in; "At the price point it attracted point-and-shooters who loved its sexy look, but care only about low-light and OIS."

And speaking of "low light", I'm in the dark. What does "OIS" mean.

Daniel Patton August 1st, 2007 12:33 PM

OIS = optical image stabilizer or stabilization

These never got answered, so I'll answer a few...

H.264 a compression scheme used for video delivery on the web (and possibly other places as well, I'm not sure)
GOP--Group of Pictures. It's the way HDV compresses video, taking 6 frames at a time and compressing them together. More efficient compression (smaller files) but it also takes longer to edit and render since your NLE has to work with the frames adjacent to the one you're trying to effect.
AVCHD--A compression scheme used in some of the cameras which record to flash media. I think this is the most "efficient" of the HD codecs, since it runs at around 13MB/s
DVCProHD--Panasonic's HD codec.
XDCAM--codec used by Sony
