Porn And Online Videos Written by: Steve, 04/19/2006

In case you missed the memo, the Internet is live and in motion! Just about
every adult site has a video component to it – and most make video the
main attraction. If you’re surfing adult sites, or any sites where you
can access videos, you will see an array of specifications that you may or may
not be familiar with. Understanding things such as video format, compression
rates and download speeds will ensure you get what you want out of your online
adult entertainment adventures!
Video quality on the Net depends on two factors: the quality of the source
video being duplicated and the method used to encode and/or compress it. Source
video can come from analog tapes, such as beta, SVHS and VHS or it can come
from a number of digital sources as well, such as Digital Betacam or Mini DV
tapes. Analogue tapes have many inherent problems. For example, every time a
tape is played it loses some of its quality. Also, when an analogue tape is
used to copy a master tape, there is additional degradation in quality during
the process. The differences between the original and duplicate tape may be
hardly noticeable, but there will be a loss of video quality. Analogue tapes
also lose quality over time as they sit on shelves, waiting for their next play.
There is little anyone can do if a poor quality analogue tape is transferred
to digital form. As the old saying goes, crap in leads to crap out.
Digital video provides an answer to this. Assuming you haven’t dropped
a hard drive with the video on it, video will appear as clean, crisp and essentially
identical every time it’s played. Also, there isn’t any degradation
in quality when you copy digital media. Every bit of information is transferred
exactly as it’s written so that the copy will appear exactly as the original.
Although it is possible for digital tapes and computer disks to lose quality
over time, the degradation is nowhere near that of analogue tapes and minor
errors can easily be corrected. 1 But although digital technology is far superior
to analogue when it comes to weighing the pros and cons of digital video, there
are certain downsides that you, as a surfer, are bound to face.
High-resolution video, such as what you see on television, requires large amounts
of data to duplicate. Most home users would have very little space left over
on their hard drives if they downloaded a handful of full-length movies at their
intended resolution. Also, videos of that size, which could take up to nine
gigabytes of space, would take an extraordinary amount of time to download –
approximately 32 hours with a typical 640k DSL connection. 2 Various ways of
encoding and compressing data have been created to solve this problem. We’re
going to take a brief look at a handful for the various formats, their strengths
and weaknesses, and what they mean to you.
Without getting too technical, there are a number of different video file types
that you will see on the web. Microsoft has two that are popular on the web,
including .avi (audio video interleave), and .wmv, their Windows Media format.
AVI files are common but can’t be played on all
non-windows computers while WMV files can be played on just about every computer
-- but you need to download an extra component and install it. MPEG videos are
also common. MPEG stands for Motion Picture Expert Group and includes .mpeg
and .mpg file extensions. These files are generally accepted on all operating
systems. Apple developed a video format of its own. It’s called Quicktime
and it can be played on their operating system and others, as long as you install
a free component. Real Media produced a format that you may come across. Real
Media files have .rm and .ram extensions. 3 From a connoisseur’s point
of view, each of these formats has different strengths and weaknesses. However,
for the layman, most can be tweaked so that video quality can be improved or
reduced, so no one file type will always appear better than another.
When a content producer is looking to crunch video, they can reduce the size
by various means. What has emerged is a technical way to describe the quality
of video without directly relating to the source itself. For example, you may
go to a site and see a trailer for download that comes in a few
different
forms. Your trailer may be a .mov Quicktime file that you can download to your
desktop and you may have three choices, a 56k option, 300k and 500k. The
“k” refers to kilobits per second or a thousand bits per second.
Broadcast quality video may be somewhere around 200 Mbps, if you were to record
it at full quality, so most video files will only be shadows of their original
selves. 4 (Mbps stands for millions of bits per second or megabits per second
and although videos of this size are much better quality, you probably won’t
find many of them online) Kbps and mbps simply refer to how much information
was retained from the original source – not the size of the file. Generally
speaking, the higher the “k,” the better quality of video. But remember,
if the video that is being recorded is of poor quality, the file that is eventually
made will also be of poor quality, no matter what the “k” happens
to be.
The final factor to consider is the rate at which a video is downloaded. Speed
is everything -- especially in adult where the need for gratification usually
requires immediate solutions. A 200-megabyte file takes ten times as long to
download as a 20-megabyte file. Do you really have enough time to wait around
for it to be downloaded? You just might, but understanding transfer rates will
help you determine whether you should download a full movie, for example, or
just a few of the scenes that may be available. First you need to look at your
connection. You may be running something like a 56k dial-up modem or you could
have a 1.5 DSL connection. There are many options above, below and in between
the two mentioned, but what we’re looking at here is the machinery that
lets you connect to the Internet and its abilities. Also, you may have a great
cable modem attached to your computer, but if there isn’t sufficient infrastructure
in your neighborhood, you may not be able to maximize the speed of your hardware.
If you’re interested in looking at video files over the Internet, we suggest
going for a high-speed connection. Hopefully your local Internet service provider
will be able to give you the bandwidth you need to download videos adequately.

based on your connection, you can try this download

Now you’re armed with a bit of knowledge that should help you navigate
the world of online adult entertainment a little easier. Check out your favorite
niche and enjoy the show!
