Scene Tags

PROPER
Due to scene rules, whoever releases the first Telesync has won that race (for example). But if the quality of that release is fairly poor, if another group has another telesync (or the same source in higher quality) then the tag PROPER is added to the folder to avoid being duped. PROPER is the most subjective tag in the scene, and a lot of people will generally argue whether the PROPER is better than the original release. A lot of groups release PROPERS just out of desperation due to losing the race. A reason for the PROPER should always be included in the NFO.
SUBBED
Usually means it has hard encoded subtitles burnt throughout the movie. These are generally in malaysian/chinese/thai etc, and sometimes there are two different languages, which can take up quite a large amount of the screen.
UNSUBBED
When a film has had a subbed release in the past, an Unsubbed release may be released.
LIMITED
A limited movie means it has had a limited theater run, generally opening in less than 250 theaters, generally smaller films (such as art house films) are released as limited.
INTERNAL
An internal release is done for several reasons. Classic DVD groups do a lot of .INTERNAL. releases, as they wont be dupe’d on it. Also lower quality theater rips are done INTERNAL so not to lower the reputation of the group, or due to the amount of rips done already. An INTERNAL release is available as normal on the groups affiliate sites, but they can’t be traded to other sites without request from the site ops. Some INTERNAL releases still trickle down, it usually depends on the title and the popularity.
STV
Straight To Video. Was never released in theaters.
ASPECT RATIO TAGS
These are “WS” for widescreen (letterbox) and “FS” for Fullscreen. Typically widescreen releases are rarely tagged that way as many people assume a widescreen format.
RECODE/RE-ENCODE
A recode is a previously released version, usually filtered to remove subtitles, fix color etc. Whilst they can look better, it is frowned upon in the scene as groups are expected to obtain their own sources. However, re-encodes are quite common on Peer-2-peer sites when members quite often release their own “improved” version. Re-encodes typically don’t work or produce questionable results simply because you cannot turn a “bad” source into a good one by playing with numbers.
REPACK
If a group releases a bad rip, they will normally release a Repack which will fix the problem. The reason for the repack should be stated in the .nfo
NUKED
A release can be nuked for various reasons. Individual sites will nuke for breaking their rules (such as “No Telesyncs”) but if the film has something extremely wrong with it (no soundtrack for 20mins or missing the ending for example) then a global nuke will occur, and people trading it across sites will lose their credits. Nuked films can still reach other sources such as p2p/usenet, but its a good idea to check why it was nuked first in case. If a group realise there is something wrong, they can request a nuke.NUKE REASONS :: this is a list of common reasons a film can be nuked for (generally DVDRip)

** BAD A/R ** :: bad aspect ratio, ie people appear too fat/thin
** BAD IVTC ** :: bad inverse telecine. process of converting framerates was incorrect.
** INTERLACED ** :: black lines on movement as the field order is incorrect.
DUPE
Dupe is quite simply, if something exists already, then theres no reason for it to exist again without proper reason.
