(I don't recall off the top of my head if subtitle overlay is yet being supported for 4k. I think it might be, but don't have a copy of the release notes in front of me... Any of these things have the potential to mess up the subtitles. I'm guessing it's a scope title and the titles are being cropped off a little by the screen file? If you're using a mixture of 2k and 4k settings, the subtitle system maybe be placing the titles lower in the frame than you need. Or it's just a bad DCP...

Screening on Saturday and Sunday.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

Subtitles reference the bottom of the image (and left edge) for placement. When you run a 2K movie on a 4K machine, the ICP will scale the image to have it fill the raster. So if you run a 4K PCF, it will place the subtitles at the bottom of a 4K image and then the scaler puts the bottom line below the screen. If you use a 2K PCF (DCDM_XYZ_185 or 239 as appropriate) instead of the 4K version by the same name, your problem will vanish. You will need separate 2K and 4K projector presets. Again, this only affects movies that have subtitles and use CineCanvas to subtitle generation. There is no problem running 2K movies with a 4K PCF (it will scale them out right), however, on a 4K projector, you cannot do the reverse (run 4K movies on a 2K PCF) but with subtitled movies, you have to match the PCF to the content.  |  IP: Logged Stephen Furley Film God Posts: 3059 From: Coulsdon, Croydon, England Registered: May 2002 posted 02-02-2016 08:20 AM                     Doremi server, NEC NC-800c, plays fine.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 02-02-2016 11:17 AM                     Stephen, You missed the nuance twice. One Doremi normally handles its own subtitles rather than depending on CineCanvas. The NC800 is a 2K projector and the Doremi is going to be an HDSDI based (DCP2000 or 2K4) so again, it will only extract the 2K portion and thereby never experience the problem. This problem is only for 4K systems when running 2K subtitled features...the projector HAS to use a 2K input/PCF configuration so CineCanvas puts the subtitles in the right place.  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 02-04-2016 03:41 PM                     With Barco, a macro was added so the PCF can switch scaling for the 4k content to show correctly through a 2k machine. Without it, the 4k image looked that it was zoomed up on the screen-we ran into that one also with losing subtitles where at first, I had to go into the PCF listing and manually change it to 4k_xyz_239 per each show until the macro was inserted.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

It is the same ICP (unless you have a Barco Alchemy), that does the scaling/interpreting of the source file/caption placement.  |  IP: Logged
