Author Topic: Difference in FTR-3D-45fl and FTR-3D-7fl Sara Helton Film Handler Posts: 3 From: St Louis, MO Registered: Oct 2015 posted 03-18-2016 01:04 PM                  Hi. When I became the manager/projectionist of my theater I was thrown in and taught myself most of what i needed to know. I have most definitely used both 45fl files and 7fl files. Can anyone tell me what the difference is. Is it the type of 3D box? Thank you for any help.  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 03-18-2016 02:59 PM                     Welcome. The difference is how the content was created for 3D showing to bring out more brightness to the screen in the digital feature. Some projectors only can use the 4.5fl content, why of the two versions. Trade name is Xtra Bright for the 7fl releases. If any doubt or question, just use the 4.5fl file for 3D presentations. Also, please use the Digital Cinema Forum where this is forum for the usage of film. Good luck - Monte  |  IP: Logged Sara Helton Film Handler Posts: 3 From: St Louis, MO Registered: Oct 2015 posted 03-18-2016 04:06 PM                  Thank you.  |  IP: Logged Mike Blakesley Film God Posts: 12767 From: Forsyth, Montana Registered: Jun 99 posted 03-18-2016 06:23 PM                        And if you're not sure if you have the xtra-brite or not, just try both. If you don't have xtra-brite, the picture will be darker with the 7fl (or 6fl) version. Just use the version that looks the brightest.  |  IP: Logged Dave Macaulay Film God Posts: 2321 From: Toronto, Canada Registered: Apr 2001 posted 03-18-2016 07:25 PM                     The images are slightly different to give a better image for either lower brightness or higher brightness screens. With the "wrong" one you will get poor detail in dark areas and/or worse ghosting in high contrast areas.  |  IP: Logged Sara Helton Film Handler Posts: 3 From: St Louis, MO Registered: Oct 2015 posted 03-19-2016 12:31 PM                  Thanks guys. I will try both.  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 03-19-2016 03:00 PM                     These differences are certainly small, and will only be visible in special scenes, usually the more dark ones. - Carsten  |  IP: Logged
