Appendix #3a   Labeling 3D Product
3D features often have both 2D and 3D versions.  3D features will also have both 2D and 3D trailers even if the feature doesn't have a 2D version.  This can be confusing since the feature title will often have "3D" in the title.  (Example: JAWS-3D.)  If the feature title is short enough, you may want to expand the Content Type field to include a "2D" or "3D" designation.  For example:        TITLE-3D_TLR-1-2D_F_EN-XX_US-GB_51-EN_2K_ST_20070115_FAC_OV      TITLE-3D_TLR-1-3D_F_EN-XX_US-GB_51-EN_2K_ST_20070115_FAC_i3D-gb_OV   Both packages use "3D" in the title field, but one trailer is listed as "2D" in the Content Type field and the other as "3D".  Also note that the 3D trailer has the i3D-gb designation to denote its 3D specs.   Although the Digital Cinema Naming Convention calls for "3D" to appear in the Movie Title field (if the DCP is in 3D), it also gives the option to add "3D" or "2D" to the Content Type field as well.  Some studios have chosen to add "3D" or "2D" to the Content Type field instead of the Title field.       1) If the movie is in 3D, "3D" should appear in the Content Type field.     2) If the movie is in 2D, it is not necessary to include "2D" in the Content Type field; it will just be assumed.     3) If the movie is in 3D, it will have both 3D and 2D trailers that need to be differentiated, so "2D" must appear in the Content Type field for the 2D trailer.     4) If the Movie Title has "3D" in it, then 3D should still appear in the Movie Title field.  (e.g.: "Step-Up-3D")   Note that adding "-3D" or "-2D" after the Content Type and Version number, expands the Content Type field to 8 characters.  In these cases, you can eliminate the hyphen after "FTR", so the field would read:  "FTR1-3D" or "FTR1-2D".  Since this is not as clear as "FTR-1-3D", consider shortening the film name in the Title field in order to accomodate the longer Content Type field.     Examples:   MovieTitle_FTR-1-3D or Movie-Title_FTR1-3D   MovieTitle_TLR-1-3D or Movie-Title_TLR1-3D   MovieTitle_TLR-1-2D or Movie-Title_TLR1-2D   MovieTitle3D_TLR-1-2D or Movie-Title-3D_TLR1-2D
3D Ghostbusting Labeling   (i3D-gb, i3D-ngb, and i3D.)
Some studios release both ghostbusted and non-ghostbusted Digital Cinema Packages.  The Naming Convention differentiates these with "i3D-gb" and "i3D-ngb".  Some 3D systems have incorporated real-time ghostbusting into their on-site equipment, so ghostbusted packages are not necessary.  These systems are becoming more and more widespread, and require non-ghostbusted DCPs.  Additionally, some content is color timed so ghosting is simply not a problem.  These packages are also non-ghostbusted.  In this case, one package will play correctly on any 3D Interop system regardless of whether the system has ghostbusting or not.  These "one package fits all" DCPs are labeled:  "i3D" without any reference to "gb" or "ngb".  If you have only one DCP, and it is non-ghostbusted, it may very well play fine on any piece of 3D equipment.
