Careful you don't a Higurashi DVD. You might Hanyuu's horns.

Math-y answer: uncompressed video is: width X height X bit_depth X frame_rate x time_in_seconds = total_size_in_bits

So, the huge number is either a bad guessing algorithm that spouts answers before it really analyzes all the data coming out of the program (much like data transfer time estimations on older versions of windows) or: 10,168,759,117,414.4 bits / (848 x 480 x 32 x 23.976) = 32561.48 seconds = 542.69min = slightly over 9 hours of video from a single d2v file.

Realistically, a single DVD should only be 1/4 of that size.

Ya but I 6 whole DVD's into a single d2v for chobits. Thats why the file size is insane.

Also whats with out the verbs in sentences? Oh I what you guys there. :awesome:
"The people cannot be [...] always, well informed. The part which is wrong will be discontented, in proportion to [...] the facts they misconceive. If they remain quiet under such misconceptions, it is lethargy, the forerunner of death to public liberty. What country can preserve its liberties, if it's rulers are not warned [...] that this people preserve the spirit of resistance? The tree of liberty must be refreshed from time to time, with the blood of patriots and tyrants."-Thomas Jefferson

I skimmed over most of this because it's just :words: but anyway, there is an excellent blogpost around (although it's down right now) about the differences between grain and noise. Mosquito noise, dirt, actual noise, and whatnot are all characterised by off-colour (usually) blocks. The difference is in the size and location. Mosquito noise tends to cover a larger portion of the image but is very small, often just 1 or 2 pixels. Dirt can be either film dirt, or on digital footage that kinda crap you get in between 2 massive chroma differences or close lines, especially on the points of hair in anime. This is what you're seeing here. Regular/actual noise tends to cover flatter blocks of colour and is just off-colour pixels, usually caused by poor quantization and/or MPEG-2. Early digital anime (circa 2004-2006) has a lot of dirt, especially on hair and edges of bright clothing against blue or grey. Might have lots of actual noise too but that is more prevalent in MPEG-2 transport streams and other bitrate starved forms of that codec. Mosquito noise tends to happen on film or when incorrectly applied grain is quantized. It is very small though and not all that common, the term is usuallyused for dirt rather than actual mosquito noise, but it is important to know the difference so you don't trash it with the wrong filters.

tl;dr dirt is on edges of hair and bright colours, mosquito noise is almost impossible to see, other noise is on flat colours, grain is good for you, eat your vegetables
