What does “OPEN MATTE” mean?
Open matte is a filming technique that involves matting out the top and bottom of the film frame in the movie projector (known as a soft matte) for the widescreen theatrical release and then scanning the film without a matte (at Academy ratio) for a full screen home video release.
The scene tag was introduced on 2016-02-07 for the rip Coyote.Ugly.2000.OPEN.MATTE.READNFO.HDTV.x264-REGRET. This is an excerpt from the accompanying NFO file:
RNFO: We are going to try something new. Rather than spam tag READNFO on all our releases with a different ar containing more picture than
the already released retail, we are going to tag them as OPEN.MATTE. As always a comparison image will be included in the Sample directory.
And, if you’re clueless as to what open matte is for some reason, read this: https://en.wikipedia.org/wiki/Open_matte
Some might argue that the tag OPEN.MATTE is invalid due to this line of the ruleset:
Other permitted tags are: PROPER, REPACK, RERIP, REAL, UNCUT, DUBBED, SUBBED, INTERNAL, OAR, PPV
However, in response to that, we say, what about these tags not mentioned in the ruleset?
Their releases still got nuked for using the tag.
