All About Movie Tags (what Is A Dvdrip, Cam Etc.

CAM -
A cam is a theater rip usually done with a digital video camera. A mini tripod is sometimes used, but a lot of
the time this wont be possible, so the camera make shake. Also seating placement isn't always idle, and it
might be filmed from an angle. If cropped properly, this is hard to tell unless there's text on the screen,
but a lot of times these are left with triangular borders on the top and bottom of the screen. Sound is taken
from the onboard microphone of the camera, and especially in comedies, laughter can often be heard during the
film. Due to these factors picture and sound quality are usually quite poor, but sometimes we're lucky, and
the theater will be fairly empty and a fairly clear signal will be heard.


TELESYNC (TS) - A telesync is the same spec as a CAM except it uses an external audio source (most likely an
audio jack in the chair for hard of hearing people). A direct audio source does not ensure a good quality
audio source, as a lot of background noise can interfere. A lot of the times a telesync is filmed in an empty
cinema or from the projection booth with a professional camera, giving a better picture quality. Quality
ranges drastically, check the sample before downloading the full release. A high percentage of Telesyncs are
CAMs that have been mislabeled.


TELECINE (TC) -
A telecine machine copies the film digitally from the reels. Sound and picture should be very good, but due to
the equipment involved and cost telecines are fairly uncommon. Generally the film will be in correct aspect
ratio, although 4:3 telecines have existed. A great example is the JURASSIC PARK 3 TC done last year. TC
should not be confused with TimeCode , which is a visible counter on screen throughout the film.


SCREENER (SCR) -
A pre VHS tape, sent to rental stores, and various other places for promotional use. A screener is supplied on
a VHS tape, and is usually in a 4:3 (full screen) a/r, although letterboxed screeners are sometimes found. The
main draw back is a "ticker" (a message that scrolls past at the bottom of the screen, with the copyright and
anti-copy telephone number). Also, if the tape contains any serial numbers, or any other markings that could
lead to the source of the tape, these will have to be blocked, usually with a black mark over the section.
This is sometimes only for a few seconds, but unfortunately on some copies this will last for the entire film,
and some can be quite big. Depending on the equipment used, screener quality can range from excellent if done
from a MASTER copy, to very poor if done on an old VHS recorder thru poor capture equipment on a copied tape.
Most screeners are transferred to VCD, but a few attempts at SVCD have occurred, some looking better than
others.


DVD-SCREENER (DVDscr) -Same premise as a screener, but transferred off a DVD. Usually letterbox , but without
the extras that a DVD retail would contain. The ticker is not usually in the black bars, and will disrupt the
viewing. If the ripper has any skill, a DVDscr should be very good. Usually transferred to SVCD or DivX/XviD.


DVDRip - A copy of the final released DVD. If possible this is released PRE retail (for example, Star Wars
episode 2) again, should be excellent quality. DVDrips are released in SVCD and DivX/XviD.


VHSRip -Transferred off a retail VHS, mainly skating/sports videos and XXX releases.


TVRip -TV episode that is either from Network (capped using digital cable/satellite boxes are preferable) or
PRE-AIR from satellite feeds sending the program around to networks a few days earlier (do not contain "dogs"
but sometimes have flickers etc) Some programs such as WWF Raw Is War contain extra parts, and the "dark
matches" and camera/commentary tests are included on the rips. PDTV is capped from a digital TV PCI card,
generally giving the best results, and groups tend to release in SVCD for these. VCD/SVCD/DivX/XviD rips are
all supported by the TV scene.


WORKPRINT (WP) -A workprint is a copy of the film that has not been finished. It can be missing scenes, music,
and quality can range from excellent to very poor. Some WPs are very different from the final print (Men In
Black is missing all the aliens, and has actors in their places) and others can contain extra scenes (Jay and
Silent Bob) . WPs can be nice additions to the collection once a good quality final has been obtained.


DivX Re-Enc -A DivX re-enc is a film that has been taken from its original VCD source, and re-encoded into a
small DivX file. Most commonly found on file sharers, these are usually labeled something like
Film.Name.Group(1of2) etc. Common groups are SMR and TND. These aren't really worth downloading, unless you're
that unsure about a film u only want a 200mb copy of it. Generally avoid.


Watermarks -
A lot of films come from Asian Silvers/PDVD (see below) and these are tagged by the people responsible.
Usually with a letter/initials or a little logo, generally in one of the corners. Most famous are the "Z" "A"
and "Globe" watermarks.


Asian Silvers / PDVD -
These are films put out by eastern bootleggers, and these are usually bought by some groups to put out as
their own. Silvers are very cheap and easily available in a lot of countries, and its easy to put out a
release, which is why there are so many in the scene at the moment, mainly from smaller groups who don't last
more than a few releases. PDVDs are the same thing pressed onto a DVD. They have removable subtitles, and the
quality is usually better than the silvers. These are ripped like a normal DVD, but usually released as VCD.


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
XMRvariable
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 Thanks for lardo4life for the info
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 -
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.


Misc Info


Regional Coding -
This was designed to stop people buying American DVDs and watching them earlier in other countries, or for
older films where world distribution is handled by different companies. A lot of players can either be hacked
with a chip, or via a remote to disable this.


RCE -
RCE (Regional Coding Enhancement) was designed to overcome "Multiregion" players, but it had a lot of faults
and was overcome. Very few titles are RCE encoded now, and it was very unpopular.


Macrovision -
Macrovision is the copy protection employed on most commercial DVDs. Its a system that will display lines and
darken the images of copies that are made by sending the VHS signals it can't understand. Certain DVD players
(for example the Dansai 852 from Tescos) have a secret menu where you can disable the macrovision, or a "video
stabaliser" costs about 30UKP from Maplin (www.maplin.co.uk)


NTSC/PAL -
NTSC and PAL are the two main standards used across the world. NTSC has a higher frame rate than pal (29fps
compared to 25fps) but PAL has an increased resolution, and gives off a generally sharper picture. Playing
NTSC discs on PAL systems seems a lot easier than vice-versa, which is good news for the Brits An RGB enabled
scart lead will play an NTSC picture in full colour on most modern tv sets, but to record this to a VHS tape,
you will need to convert it to PAL50 (not PAL60 as the majority of DVD players do.) This is either achieved by
an expensive converter box (in the regions of £200+) an onboard converter (such as the Dansai 852 / certain
Daewoos / Samsung 709 ) or using a World Standards VCR which can record in any format.
