Whenever we are downloading a movie from any of the internet source,
then the movie files name is a long name with some tag line except the
original name of the movie. These tags line describe the original source
of the video.By showing these tags we can choose a better quality of
the video.
CAM -
This is a theatrical rip. This is generally a recorded video from
theater using Digital Video Camera. So the sound and video ualiy of the
videos are not so good.
TELESYNC (TS) -
This is same as the CAM except that an extra additional audio recorder is used.
TELECINE (TC) -
A telecine machine copies the video and audio directly from the reels.
So the audio and video quality may high but the cost of the equipmant
used are very high.
SCREENER (SCR) -
A screener is used in pre VHS tape that are provided to various stores
for promotion. Its quality may varie from xcellent to very poor
according to the captured device used in tapes.
DVD-SCREENER (DVDscr) -
It is same as the screener but transferred offa DVD.
DVDRip -
This is the copy of finally released DVD.
VHSRip -
Transferred off a retail VHS, mainly skating/sports videos and XXX releases.
TVRip -
These are recorded from Tv either using digital cable/settop boxes ordirectle record from internet.
WORKPRINT (WP) -
This is the copy of the film that has not been finished.

Formats:
VCD -
VCD is an mpeg1 based format, with a constant bitrate of 1150kbit at a
resolution of 352x240 (NTCS). VCDs are generally used for lower quality
transfers (CAM/TS/TC/Screener(VHS)/TVrip(analogue) in order to make
smaller file sizes, and fit as much on a single disc as possible. Both
VCDs and SVCDs are timed in minutes, rather than MB, so when looking at
an mpeg, it may appear larger than the disc capacity, and in reality u
can fit 74min on a CDR74.
SVCD -
SVCD is an mpeg2 based (same as DVD) which allows variable bit-rates of
up to 2500kbits at a resolution of 480x480 (NTSC) which is then
decompressed into a 4:3 aspect ratio when played back. Due to the
variable bit-rate, the length you can fit on a single CDR is not fixed,
but generally between 35-60 Mins are the most common. To get a better
SVCD encode using variable bit-rates, it is important to use multiple
"passes". this takes a lot longer, but the results are far clearer.
XVCD/XSVCD -
These are basically VCD/SVCD that don't obey the "rules". They are both
capable of much higher resolutions and bit-rates, but it all depends on
the player to whether the disc can be played. X(S)VCD are total
non-standards, and are usually for home-ripping by people who don't
intend to release them.
KVCD -
KVCD is a modification to the standard MPEG-1 and MPEG-2 GOP structure
and Quantization Matrix. It enables you to create over 120 minutes of
near DVD quality video, depending on your material, on a single 80
minute CD-R/CD-RW. We have published these specifications as KVCDx3, our
official resolution, which produce 528x480 (NTSC) and 528x576 (PAL)
MPEG-1 variable bit rate video, from 64Kbps to 3,000Kbps. Using a
resolution of 352x240 (NTSC) or 352x288 (PAL), it's possible to encode
video up to ~360 minutes of near VCD quality on a single 80 minute CD-R.
The mpeg files created will play back in most modern standalone DVD
players. You must burn the KVCD MPEG files as non-standard VCD or
non-standard SVCD (depends on your player) with Nero or VCDEasy.
DivX / XviD -
DivX is a format designed for multimedia platforms. It uses two codecs,
one low motion, one high motion. most older films were encoded in low
motion only, and they have problems with high motion too. A method known
as SBC (Smart Bit-rate Control) was developed which switches codecs at
the encoding stage, making a much better print. The format is Ana orphic
and the bit-rate/resolution are interchangeable. Due to the higher
processing power required, and the different codecs for playback, its
unlikely we'll see a DVD player capable of play DivX for quite a while,
if at all. There have been players in development which are supposedly
capable, but nothing has ever arisen. The majority of PROPER DivX rips
(not Re-Encs) are taken from DVDs, and generally up to 2hours in good
quality is possible per disc. Various codecs exist, most popular being
the original Divx3.11a and the new XviD codecs.
CVD -
CVD is a combination of VCD and SVCD formats, and is generally supported
by a majority of DVD players. It supports MPEG2 bit-rates of SVCD, but
uses a resolution of 352x480(ntsc) as the horizontal resolution is
generally less important. Currently no groups release in CVD.
DVD-R -
It is the recordable DVD solution that seems to be the most popular (out
of DVD-RAM, DVD-R and DVD+R). it holds 4.7gb of data per side, and
double sided discs are available, so discs can hold nearly 10gb in some
circumstances. SVCD mpeg2 images must be converted before they can be
burnt to DVD-R and played successfully. DVD>DVDR copies are possible,
but sometimes extras/languages have to be removed to stick within the
available 4.7gb.
MiniDVD -
MiniDVD/cDVD is the same format as DVD but on a standard CDR/CDRW.
Because of the high resolution/bit-rates, its only possible to fit about
18-21 mins of footage per disc, and the format is only compatible with a
few players.
