Author Topic: TWO-perf splices... Jon Miller Jedi Master Film Handler Posts: 973 From: San Diego, CA, USA Registered: Sep 1999 posted 10-18-2003 01:46 PM                     Going in the opposite direction from the 8-perf splicing tape thread... Who makes (or made) two-perforation splicers? Does it use narrow tape, or perforated 35mm splicing tape (like a Rivas). Was it used for editing? No, I don't want one. The reason I ask is because in June 2002, I ran several reels of clips for a seminar on obtaining the best DV-to-35mm transfers. Almost all of the clips were spliced using a two-perf splicer; most of the splices were starting to separate from the stress of projection and had to be remade before the show. Since the clips arrived around 7:00 in the morning for a 9 AM presentation (not the day before, as I had requested), I could only re-do splices showing signs of separation, not every splice as I would have wanted to do. Fortunately, everything ran fine (using a single-projector reel-to-reel setup with a Simplex E-7 in a local museum), but I almost wanted to strangle whomever made up the clip reels with two-perf splices.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 10-18-2003 02:55 PM                     2 perf splice is standard on the zigzag splicers used on 15/70 film but I haven't seen it used much anywhere else  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 10-18-2003 03:56 PM                     It's just someone using 19mm width splicing tape (like would be used for 16mm films) on a regular splicer. It works ok provided the splicer is in good condition and high quality 19mm splicing tape is used.  |  IP: Logged Manny Knowles "What are these things and WHY are they BLUE???"

On a 1.85:1 movie you didn't see the splice. The tape was white opaque and super-adhesive; we never had a jam in projection.  |  IP: Logged Max Biela Film Handler Posts: 89 From: Dortmund, Germany Registered: Sep 2003 posted 10-18-2003 04:42 PM                     Brad, all 16mm Splicers I've seen used 15mm wide tape to cover 2 frames of 16mm film. Here in Germany many cinemas use this stuff for 35mm to prevent SRD from dropping out. BTW I've had no drop outs using 38mm wide tape (using Kinoton basement readers and a CIR splicer).. For splicing trailers we use normally the 19mm wide tape because its cheaper and easier to peel (less tape). Were can I get a few infos about those 1-perf splicers? Sounds interesting!

USA (1774.21 miles northeast of Dallas) Registered: Jun 99 posted 10-18-2003 10:36 PM                        I tried using 16mm tape on 35mm film once, using junk film. It seemed to work OK, but I wouldn't personally use it except in an emergency (e.g. if the supply of 35mm tape has run out). SRD shouldn't have any problems with dropouts when using normal 1" wide 35mm clear splicing tape. Manny--is the 1-perf splicer the type that uses pre-perforated tape? I think I've seen something like that designed for 16mm film.  |  IP: Logged Manny Knowles "What are these things and WHY are they BLUE???" Posts: 4247 From: Bloomington, IN, USA Registered: Feb 2002 posted 10-18-2003 11:18 PM                     Scott -- Yes. It uses the preperforated tape. The splicer itself is a modified butt splicer with the blade that comes down in the middle of the block and a little tap-n-cut razor blade that swings in to cut the tape. Everything is the same except for that tap-n-cut razor part. That's the bit that got modified. I was told that Paul Hirsch, the editor, invented the modification and owns the name Inviso. Never checked whether that story was true.  |  IP: Logged Jon Miller Jedi Master Film Handler Posts: 973 From: San Diego, CA, USA Registered: Sep 1999 posted 10-19-2003 02:34 PM                     Manny, I think the splices may have been "Inviso" splices, but made with clear tape. The splice width was less than 8mm, so it could not have been a splice made with splicing tape for 16mm film. I vaguely recall the splices not fully overlapping the perforations to either side of the centerline. Whatever tape they used was definitely not super-strong as you suggested the Inviso tape was. I wish I had taken pictures of those splices. I had my digital camera with me, but time was so tight that I had to repair as many splices as possible to run the clip reels with complete confidence. As some of the reels had four or five minutes' worth of short clips (about 15 seconds apiece), there were quite a number of splices to fix.  |  IP: Logged
