Author Topic: Print drops out of Dolby Digital at beginning Mike Blakesley Film God Posts: 12767 From: Forsyth, Montana Registered: Jun 99 posted 05-11-2008 11:13 AM                        We're playing "Forgetting Sarah Marshall" because all you big city guys have all the "Iron Man" prints! Everything runs fine in digital right up through the end of the trailers, thru the Dolby Digital "train" tag, and then at the very beginning of the feature, you hear this loud "motorboating" type sound from the speakers for about 1/2 of a second and then it flops to analog and stays there for the whole movie, indicating "F" on the CP650. I've remade the splice between tag and feature (even though it looked fine) and stood by watching the machine when it runs -- nothing seems or sounds amiss. I think my next step will be to remove the Universal logo footage to give the feature a new 'starting point' and see if that works, unless anybody has some alternate ideas. (I would just remove a few frames before the logo starts, but some bonehead in a previous theatre cut off nearly all of the black before the image begins, so I'd rather have no logo at all than a chopped off one.)  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 05-11-2008 01:30 PM                        There is such a thing as a bad reel. You could remove reel one while you are off screen and then run trailers then reel 2. If OK, then reel 1 is bad. Alternatively. reboot the CP-650 after reel 2 starts and see how it goes.

(There is no volume adjustment for this, so hopefully your tech preset this.) The CP650 will probably keep you there for about a minute during the reboot process.  |  IP: Logged Darryl Spicer Film God Posts: 3250 From: Lexington, KY, USA Registered: Dec 2000 posted 05-11-2008 03:42 PM                    was this a new or used print? If used the whole DD track could hae a scratch going through it.  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 05-11-2008 04:46 PM                     Am I wrong or the Bypass level of CP650 can be adjusted rotating the volume knob, even if the display does not indicate anything? Of course the initial bypass level is set by the "bypass" trimpot on the front. The only issue is that at the end of the reboot the 650 (at least my 2.2.5.0 release) will test the 6ch input and analog projector inputs, removing the sound for a second or two. I think that even the worst splice in the world cannot force your CP in "F" more than half a second. I suppose that if other reels and trailers work properly, the SRD soundtrack at the beginning of the reel is faulty.

Mark  |  IP: Logged Mike Blakesley Film God Posts: 12767 From: Forsyth, Montana Registered: Jun 99 posted 05-11-2008 10:34 PM                        It's a used print, but I don't see any visible scratches. I took a very close look at the first few feet of film and found some leftover gunk from an old lighting cue that I missed before...A little Film-guard took that off and it still is not playing in digital, but at least that stopped the wierd motorboat sound at the very beginning. We have a pretty good crowd tonight so I'm not going to try rebooting the machine mid-show, but will try it during the end credits and see if it works and how it behaves. If that works, I'll do it when reel 2 begins tomorrow and see what happens. Thanks for the help guys.  |  IP: Logged Bill Gabel Film God Posts: 3873 From: Technicolor / Postworks NY, USA Registered: Jan 2002 posted 05-12-2008 06:26 AM                     quote: Mike Blakesley I don't see any visible scratches. A few years ago I had a new print come back from the Toronto Film Festival. Other than being plattered it looked in good shape. Well less than a minute into it it popped into SR from SRD for the rest of the show. (I'm change-over house) After reel one got off the number one machine I took it over to the bench and with a photo lupe looked at the SRD track. It had a very small nicks on the track, but to the regular eye it look fine. The rest of the film reels were damaged.  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 05-12-2008 07:25 AM                     The SRD decoding can be performed with an heavy scratch if the scratch is at the center of the SRD square. If there is, say, a very very small scratch on the edge of the SRD square (that damages the corners of the SRD data) the processor will probably drop to analog. I had prints with so very small damages, but in the wrong place, that faults continuously. Others with heavy scratches at the center of the SRD data block that just read high but does not faults. Hope this can help.

If the previews play fine in digital then the print has to be bad.

I rebooted the machine during the end credits last night and it went right back to analog again. I'll get out the ol' magnifying glass tonight and see if I can see anything.  |  IP: Logged Sean McKinnon Phenomenal Film Handler Posts: 1712 From: Peabody Massachusetts Registered: Sep 2000 posted 05-12-2008 10:05 AM                        I would definately order a new print, and tell them that you recieved the print like this.  |  IP: Logged Alban Birch Film Handler Posts: 63 From: Luxembourg-city , Luxembourg Registered: Jan 2007 posted 05-12-2008 11:42 AM                        I once got a print where the SRD-Track was badly aligned. Since it was the only Print playing in SRD and the rest in DTS, I changed the lateral Position of the CCD on my Cat.700. And voila, it played with a nice 3-4, had to realign everything though for the following Week.  |  IP: Logged Mike Blakesley Film God Posts: 12767 From: Forsyth, Montana Registered: Jun 99 posted 05-12-2008 12:12 PM                        quote: order a new print, I would, except we are only booked thru Wednesday, and the new print wouldn't arrive until then! I could "overnight" it here for tomorrow, but that would likely cost more than we will gross for the two days put together.  |  IP: Logged
