This is my first time to play optical films.

I had several different reels to tray. One/two reels sounded good in my projector (GS1200) but several reels produced quite "blurpish" sound, if you know what I mean, i.e very unclear sound where the dialog was heard like people speaking gibberish language.

So what make this? Is the optical track has gone from my films or the exciter lamp need alignment?

thanks

Hi Winbert.

I would recommending contacting John Gledhill of http://bitworks.org/. He is an actual engineer and an expert in recovering optical soundtracks of any format. He is very approachable.

Well done Winbert! I hope that you enjoy many a good optical feature on it!

Thanks Osi, but I am wondering what make the sound of some films so blurping? Is it the projector or the optical track?

Hi,
I had the same problem, when my features started to fade!
The optical track faded too...
and so the sound became dull!
Now my "Cabaret"-feature is silent...

That is a sad truth that the optical track can in fact fade before the other colors on the print fade, to a very light purple in truth.

I have never ran into an optical sound print with absolutely no sound left, but I have ran into some with very light sound to be sure.

I can't account for the "blurb" though. Can you perhaps explain it in some different way?

Do you mean flutter? you can get this if the lower loop is lost below the gate.

hello i have from russia with love optical print
and apart from the last reel sound is very good
so when buying optical prints it is a bit of a
gamble if the sound goes because print has faded [Confused]
