I don't think there is anything wrong with the projector as other prints play fine. What I am going to try when I get in there this morning is to do the paper towel/Filmguard thing against the edge of the film. No need to do the underside since that doesn't seem to be an issue. I might have to do this once every few days.

That's nothing!

I saw a projector that had the shoe out of line. They played the Technicolor print of Gone With the Wind in that machine and it literally looked like it was snowing! The projector was caked so full of pink crap that it had to be vacuumed out between every show.

It's gotten much worse. The blue flakes are now blue chunks. It is now running EXTREMELY rough through the projector. The Dolby Digital cuts out early on not because of track damage, but because the lens can't see the film due to the chunk accumulation. It needs to be constantly blown off every show. A new print will arrive tomorrow morning from the labs.

I was talking to my manager about this today, wondering if they had a mess-up with the waxing or whatnot. He said that it was almost as if they missed a step. He might be on to something.

quote: John Wilson
If it really was the print, wouldn't both edges of the media be showing the same damaged flakes? Why only on the edge closest to the track?
I wondered that myself.

quote: John Wilson
When you physically inspect the print itself, do you see any other damage?
Nope. Only the outboard SDDS track features any kind of damage or deterioration aside from the fact that the entire print is "hella" dirty because of this.

quote: Ian Parfrey
Can you put up a macro shot of the film itself?

I'd like to see if the emulsion is getting stripped off by something or if it is flaking of it's own accord.

Long gouges will indicate stripping by mechanical trauma whereas random clumps of emulsion-less areas indicate emulsion brittleness

I didn't take my camera with me today, but I can assure you that the damage is random. Looking at the film today, the damage starts right at the splice between the last trailer and reel 1. The outboard SDDS track is practically gone now. But it remains perfectly intact on the trailers, most of which have been with the print since it was new.

bottom line is all it takes is one pass through the machine to cause damage that will cause infinte shedding every time it plays
Polyester stock is subject to Z axis damage that will cause it to break down and shed
Also it is impossible for a entire print to have the same lab flaw

Then explain the following (I expect answers for each of the following points):

-Why are the trailers not damaged?

-Why are the cues, which are on the outboard SDDS track, unscathed?

-Why only the SDDS track?

-How could this damage be caused while the print still runs (presumably without any extra noise because this one always starts earlier than the rest and would have been heard chattering away)?

I think you mean "improbable".

I think the problem could have been exacerbated by a misthread as I said before, especially since I saw the blue flakes since the print was new, but I have never seen anything of this magnitude and I've seen people run film in some pretty funky ways.
