Author Topic: Waltz With Bashir 25 f.p.s. ?? Jack Theakston Master Film Handler Posts: 411 From: New York, USA Registered: Sep 2007 posted 06-25-2009 12:09 PM                     Do your audience a favor and run the film at 48fps. They will thank you for it later.  |  IP: Logged Scott Norwood Film God Posts: 8146 From: Boston, MA.

Obviously, if you have the capability of running at 25fps, then you should do so. The only way that I know how to tell if a particular print is 25fps is by checking the leader: if it is marked in seconds and has 25 frames instead of 24 per second, then the print is to be run at 25fps. Is there any other way to tell?  |  IP: Logged John Hawkinson Film God Posts: 2273 From: Cambridge, MA, USA Registered: Feb 2002 posted 06-25-2009 12:49 PM                     Well, sometimes music can be obvious too. Especially, but not exclusively, to people with perfect pitch. --jhawk  |  IP: Logged Sean Weitzel Jedi Master Film Handler Posts: 619 From: Vacaville, CA (1790 miles west of Rockwall) Registered: Dec 1999 posted 06-25-2009 01:00 PM                     Some years ago, I bought a PAL dvd of a guilty favorite of mine "Raise the Titanic" I grew up watching an NTSC VHS of it taped from HBO in the 80's. When the DVD arrived, I put it in my Cyberhome DVD player that can playback PAL discs and output NTSC. The 25fps transfer was immediately noticable with the John Barry score over the opening credits. I don't have perfect pitch by any means, but I couldn't watch the movie because it just sounded too 'wrong'. I gave the disc to my brother who imported it into his computer and did some magic video wizardry and created a 24fps version and burned me a new copy.  |  IP: Logged Julio Roberto Jedi Master Film Handler Posts: 938 From: Madrid, Madrid, Spain Registered: Oct 2008 posted 06-25-2009 01:54 PM                    It's our very own friends at Dolby that make the standard equipment 585 Time Scale Processor for these types of endevours http://www.dolby.com/uploadedFiles/zz-_Shared_Assets/English_PDFs/Professional/152_Model585.Manual.pdf Yeah, music, if you are a musician or very familiar with the piece, you can tell it's a tad fast (4%) if you pay attention, specially if you are used to listening to it in NTSC which is a tad bit slow to begin with (23.97 against 24). If you are not familar with the piece, well, then you assume that's the beat it's meant to be. The pitch is always digitally adjusted during transfers, though, and you'll be hard pressed to notice any difference whatsoever. If you were trying to playback a PAL disc on a DVD player that changed it to NTSC (29.97) .... well, the net effect would be a SLOW DOWN of about 4% which I doubt your DVD player was digitally pitch-correcting ... Either watch a PAL disc at 50i on a PAL TV or an NTSC 29.97 disc (or 23.98 disc which the player will output at 29.97) on an NTSC TV at 59.94i (typically, until recently) ... if you try to convert-on-the-fly, it's up to your player to time-shift and pitch adjust, which pbbly will suck ...  |  IP: Logged John Wilson Film God Posts: 5438 From: Sydney, Australia.

Like I said, I've had DTS hold at 30fps and it all sounded normal (not like Christopher Lloyd at the end of Roger Rabbit at all) but only skipped large sections as it went to stay in sync.  |  IP: Logged John Hawkinson Film God Posts: 2273 From: Cambridge, MA, USA Registered: Feb 2002 posted 06-25-2009 05:10 PM                     While we're being embarassed about this, there were two of these this season. Jeffrey Johnson said on the FITA that it was claimed on the CML list on 12/9/2008 that Slumdog Millionaire is supposed to be in 25fps as well. I thought Jao Ho sounded a bit funny, but just chalked it up to differently-tonal Indian music... Yes, John, I'm sure. The worst case we had came about shortly after we installed DTS, and it turned out our two projectors were slightly off-speed from each other. When doing a changeover from our trailer reel to reel 1 of a feature, we would hear the DTS player pitch-bend the audio to compensate for the speed difference, across its 300ms crossfade. This invariably lead to the last note of the DTS trailer (basically a sine wave) shifting in pitch dramatically. It sounded really bad. I can't account for your 30fps behavior. Why the heck would you be running 24fps content at 30fps? If it was a 30fps soundtrack, it would sound right at 30fps, of course. --jhawk  |  IP: Logged John Wilson Film God Posts: 5438 From: Sydney, Australia.

Well obviously it was a test to see what would happen. What did you think...I wanted to get home early?  |  IP: Logged Tim Reed Better Projection Pays Posts: 5246 From: Northampton, PA Registered: Sep 1999 posted 06-25-2009 08:19 PM                       25fps is/was the speed for British television film. It's easy to match to the 50Hz rate. I always suspected that the Michael Apted series, "28 Up," "35 Up", "42 Up," etc. were 25fps shows, since the published running times never matched the movies, and since they were originally made for British television.  |  IP: Logged Joe Redifer You need a beating today Posts: 12859 From: Denver, Colorado Registered: May 99 posted 06-26-2009 02:54 AM                        Dolby Digital CANNOT be played backwards!  |  IP: Logged
