Sometimes you think something is right, just because nobody ever did it different.
.
Well, a couple of issues were set in stone
without public input or discussion
without reason or discovery
.
When the Scene decided 624 X 352
They got it wrong. It was too small
The correct answer is: 640 X 360
.
For good or for ill, the video standards
have a reference and a reason
.
You know 720p and 1080p, but not 360p
.
1080p is 1920 X 1080 (2073600)
But note that 1920 + 1080 = 3000
.
720p is 1280 X 720 (921600 pixels)
But note that 1280 + 720 = 2000
.
360p is 640 X 360 (230400)
But note that 640 + 360 = 1000
.
And there is a relationship between them:
2073600 = 921600 + 5 * 230400 EXACTLY
.
This can be seen easier if you do blocks not pixels
.
640 X 360 = 1 block (1 squared)
1280 X 720 = 4 blocks (2 squared)
1920 X 1080 = 9 blocks (3 squared)
So, 9 = 4 + 5*1 visualize it
.
Where 9 9s are a big block,
Where 4 4s are a medium block,
Where 5 1s are small blocks
999 = 111
999 = 441
999 = 441
You could put five 640 X 480 screens
Plus one 1280 X 720 screen in the same
space as one 1920 X 1080 screen
.
That's why the Scene screwed up
.
.
Now, 1024K bitrate is equally arbitrary,
but this time they wanted a nice
round number.
.
You'll note that in the Scene's x264 world,
bit rates are all over the map as they have
wizend up to let bitrate be mandated by
quality, not convention.
.
Bitrate is individual
while resolution is relative ... unless you
want to know how many 1024K
bitstreams can fit down a fibre optic
cable at once. But that is completely
non standard. Depends on the cross
section of the cable and whether it's
dark or light.
Light means there is a signal in the
fibre, Dark means you make your
own upon transmission. The former
can be owned, the latter can be
flexible and forward compatible.
.
Anyway, during my time of uploading
AVIGUY torrents (nine very FUN months),
I deliberately chose 768 as being 3/4
of 1024 and my files were proportionally
smaller. The folks who treated the
Scene as holders of the true faith would
drop by from time to time to tell me how
wrong I was. But the proof is in the
pudding.
.
People were amazed at how fast my
uploads would deliver data to so many
So fast, in fact, that KAT initially banned
me for posting fakes ... until I proved
what was going on.
.
I would encode a file (much like the one
I'm posting here) and upload it. For
as long as I had the only complete file,
it was a little bit slow (2Mb/s). But once
there were multiple copies out there, a
really amazing cascade event would take
place where thousand were getting high
throughput continuously for weeks.
.
But that only works if you have a file
that 'thousands' want ... and I did.
.
In any case, I've decided to up it to
800K (~80% up from 75%), hence the
AVIGUY800 so my bitrate will be
known (or 768 or 256 (272p) for
unlabeled AVIGUY posts).
.
My 272p 256K Green Lantern was AOK.
.
.
Oh, there is one other cool relationship:
Remember 4:3? (4^1:3^1)
Remember 16:9? (4^2:3^2)
next is clearly 64:27 (4^3:3^3)
Which are respectively:
1.33
1.75
2.35
Which are motion picture aspect
ratios (2.35 is either 35mm
anamorphic or 70mm)
The film industry was initially
1.33 (old timey b/w movies)
Until the 1950s when TV used
the exact same aspect ratio.
.
But the film industry had a big
advantage: lenses and aperture
plates. Did you know 1.75 film
is not wider than 1.33, it is in
fact shorter, but magnified until
the 1.75 height matched the 1.33.
1.33 uses the whole height of
the frame, 1.75 does not.
.
Anamorphic lenses take a 1.33
image, shorten and widen it by
deforming the image. Looking
at 35mm anamorphic film stock
shows everything wildly too tall
and thin. All 35mm film stock is
four sprocket holes tall. 70mm
film is twice as wide, but only
five sprockets tall.
.
Anyway:
4 squared is 16
3 squared is 9
4 cubed is 64
3 cubed is 27
Therefore:
2.35 is 1.33 Hcubed by Vcubed
1.75 is 1.33 Hsquared by Vsquared
.
Down yet another mathematical rabbit hole with,
.
