Author Topic: Can a 70mm 30fps run on a platter? Bill Carter Expert Film Handler Posts: 162 From: Minneapolis, Minnesota Registered: Sep 1999 posted 05-18-2006 09:49 AM                     The SPECO can do it fine, but you do have to give it a helping hand when starting up in order to get up to speed before it starts to wrap. Once you do that the platter handles the show just fine, it just has trouble ramping up speed that quickly from a dead stop. The Heights has run the Todd-AO print of Oklahoma several times over the past few years, both changeover and platter. The last time (fall '95), this print was far more worn and damaged than before.  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 05-18-2006 02:45 PM                     What brand and model of platter are you using?  |  IP: Logged Ken McFall Jedi Master Film Handler Posts: 615 From: Haringey, London.

The plate's run at their fastest at the beginning of the film. At the end of the film the plate is running quite slow. Depending on the make of non-rewind you use I'd recommend the Film-Teck platter ring.... However if your non-rewind is edge driven then that's not an option for you.  |  IP: Logged Carl Martin Phenomenal Film Handler Posts: 1424 From: Oakland, CA, USA Registered: Feb 2002 posted 05-19-2006 03:55 AM                        oklahoma at 30fps is showing in san jose at the california theater may 28-june 1, i would guess changeover but i don't really know. i've never been there but hope to make it. sounds like i can expect a worn print.  |  IP: Logged Paul Vollmers Expert Film Handler Posts: 161 From: Sister Lakes, MI, USA Registered: Jul 2001 posted 05-19-2006 06:12 AM                     Brad, I just recently purchased a used 5 tear 35/70mm platter......I believe its a Strong/Balco, however I don't have it as yet.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

So which ever track is laying next to the platter surface will be too close to this magnatism at each rib.  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 05-19-2006 08:58 AM                     Paul, you've got more balls than I do (or you don't care too much about that print). No way would I trust a 70mm print, let alone a 30fps 70mm print to that platter. Good luck.  |  IP: Logged Paul Linfesty Phenomenal Film Handler Posts: 1383 From: Bakersfield, CA, USA Registered: Nov 1999 posted 05-19-2006 09:45 AM                     quote: Carl Martin oklahoma at 30fps is showing in san jose at the california theater may 28-june 1, i would guess changeover but i don't really know.

This page from the Widescreen Museum states that a new 70mm print showed in Seattle last year (scroll to the bottom).  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 05-19-2006 03:13 PM                        5 deck platter, Strong/Potts, has insufficient room between decks for 70mm. (You could remove the offending decks/arms.)

That would've been paying out quicker than 30fps 5/70.  |  IP: Logged Paul Vollmers Expert Film Handler Posts: 161 From: Sister Lakes, MI, USA Registered: Jul 2001 posted 05-20-2006 07:13 AM                     so....it looks as though the 30 FPS speed is not an issue, just keep an eye open at start up..........and possibly maybe a magnet problem.. I'll have to check when I get the platter...and set up. I have a tech to help me on that etc. I have seen 70mm 30 FPS go through a Norelco DP70 and it is really moving....but a great picture image on the screen.  |  IP: Logged Paul Vollmers Expert Film Handler Posts: 161 From: Sister Lakes, MI, USA Registered: Jul 2001 posted 05-21-2006 05:43 AM                     Brad, What 5 tear 35/70mm platter would you choose? and why? Paul--  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 05-21-2006 08:50 AM                     Because of the less space I would not recommend and 5 deck for 70mm apps If more than 3 is required the old Specco 4 deck will work  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 05-21-2006 12:21 PM                     Gordon and Louis already answered that question, it's all about the spacing. I wouldn't trust any platter with 70mm film except a Christie AW3 or late model Kinoton. Do note that the Christie 5 deck does have enough spacing to work with 70mm, although it is tight because of cramming 5 decks onto the tree. Christie also makes a 4 deck version, but 3 deck systems can be found pretty easily on the used market which is what I am assuming you are looking for. I've got plenty of 70mm Christie conversion kits if you need. Bear in mind those Strong rings are teeny tiny, so that thing will be FLYING at 30FPS on 70mm at startup...plus the major wrap issue you will have upon startup.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!
