[tig] Cyan Dye Tracks

Hi Maria,

It's right that the white light will not be enought for the Cyan tracks.
After tests here, we saw that we might loss around 12db, and win some noise !

We can still hear the sound, but it is unaccepteable for a mastering !!

I had already contacted Cintel, but they have nothing ready for the moment, maybe for the beginning of the next year !
Anyway they said that they should add an external reader or find a filter system for the actual reader, but they will not develop a huge hardware.

Unfortunatly I didn't contact Thomson yet about this problem but I will do it very soon.

But it's right that the vialta is correctly equipped ( for the high magenta, it was working well ).

Telecine factories say that the main part of their customers using a telecine for negative transfert only and not for positive transfert.  
But there is also a lot of work in laboratories for positive film ( transfert of trailers for tv's, transferts of original versions films for sub-titling or dubbing, ... )

So please give us a way to read Cyan Dye Tracks correctly !

thanks to Bob Lovejoy for supporting the TIG.
Hello all,

Over the next few months, major studios will begin releasing films 
with cyan dye optical sound-tracks.

To play the new analog sound-tracks your projector must be equipped 
with a visible red light analog optical reader.

Film labs all around the world will be striking composite prints with 
cyan dye tracks that will be UNPLAYABLE on our white light equipped 
telecine optical readers.

Please help.  I have several 35mm lo con composite prints with these 
cyan tracks; the original sound is in Japan and I am told exists as 
optical neg only.  I need to use these opticals "as is" in telecine.

Looking for a cost effective way to do this.  Remember, I must use 
the picture off these prints, so a modified dubber is not the way to 

I don't think I am the only poor sap who uses composite lo cons in telecine.

Thanks for any and all input on this new twist in our community.

M. Palazzola
