Re: follow up on sonic splicing of acetate base film.

Mr. Brand,
   
  This film was shot on 5279 and printed on 5360, both according to the Kodak website are acetate based. Perhaps the guys in the microfilm lab were mistaken in telling me I was using a sonic splicer. This machine leaves a tiny (but very visable) splice with narrow ridges running from sprocket to sprocket (yes, the frameline lining-up is tricky). When I make the splice, a tiny metal drum rolls over the cut. Does this sound like a sonic splicer? If so, how am I making what seem to me (and others) like solid splices?
   
  Best,
  Adrian

  No. This is not correct. You cannot splice acetate film with an
ultrasonic splicer. An Ultrasonic splicer works by melting the
polyester base (right through the emulsion - no scraping necessary!)
but it simply does not work with acetate. For polyester film, its a
nice devise and makes archival strength splices but they are more
visible than one made by a conventional cement splicer. You cannot
use an ultrasonic splicer for A&B roll editing. The splice overlaps
two frames and does not line up with the frameline.
