In my rush to make this video between classes, I forgot to do framing when threading! When you place the film into the gate, make sure the frame is in frame in regards to the aperture plate. If you fail to do this (like I did) you will need to adjust framing when the film starts, and the audience will not like that!

I didn't want to mention it, because I was sure you simply forgat to do while on camera,it and I didn't want to criticize gratuitously, however it is one of the most important things a projectionist must do every time the projector is threaded, and one that has often mystified beginning projectionists. The DP-70 eliminates part of the mystery, being the only projector that comes to my mind where the gate cannot be opened unless the intermittent is in "rest" position, but of course placing the leader in the correct position, and making sure whatever leader you are threading on is spliced in frame with the film are both equally important aspects. Thanks for the film.

I was a projectionist right at the end of film distribution. Miss that job all the time, it was a great feeling.

I really miss threading films. I used to be a theater manager for Showcase theaters, and they sent me to school to learn how to use the projectors, splice films and build prints. I had so much fun! This was a lot of fun to see. I can't believe I remembered, as you were going, what the next steps were!

Thanks for making this beginner video on threading a projector! I am just getting into 35/16 collecting and so happy to see new content on KZread since there isn’t a whole lot on here. Keep up the good work! I would love to see a extensive overview of splicing and using perf tape! But, I am sure anything is good too! Thanks!

I was a projectionist in the late 60's and into the seventies and just before the multiscreen theatres became common. Loved the job. I liked the Super Simplex and Simplex XL and threading a projector was super simple back then. We also mostly used carbon arc lamp houses which also doubled as dinner heaters.

That is a fantastic story! I’ve only had the pleasure to use a carbon arc a few times, but man is it fun.

Nice to see. I ran these for a few years. I had a lot of work on them to get them stable and have the shutter timing good. Most of the pertinax wheels inside were worn out. You can see on your film the effect of the electro magnetical field from the rectifier when you start your xenon. Nice done.

Nice demo. Thanks for this video.

Very intresting video, well presented, please keep up the good work.

Thanks for your video! The DP70 was my first contact with a 35mm cinema projector when I was 12 years old. :-)

This is awesome. How does the change over work?

Very. best projector. all parts good. Working. good information ,, thanks,,

I would add that it is good practice to close the lamp house douser before hitting stop, even though it seems your system's "stop" is wired to the changeover shutter? I couldn't tell if it killed the lamp too. But with lots of setups all that is separate, and just stopping your motor does NOT kill the light through the aperture. That is one easy way to burn a frame. Douser first is a more system-agnostic muscle memory to develop.

@@clickykbd Clickybd, I think you may be deluded about how many of these positions still remain, and in particular about the assertion that demand will be increasing. I was a projectionist for over 20 years, working my way up from local movie theaters to some of the most prestigious 70mm venues anywhere. I moved on to bigger and better things, designing and implementing theaters and audiovisual systems, but for years I felt my skills could serve in retirement, as a lower-stress supplemental income doing something I was very skilled at, but as I observe today the depth of penetration of digital presentation I understand that will simply not be possible. I quoted a job just last year for a small museum, where they had a film that had been made for them years earlier, which they would present at certain times every day for museum visitors. They had had a scan made from the film, and they were asking me to design a new, fully automated digital system so they could finally remove their two part-time projectionists from the payroll. Institutional, industrial, touristic and indie productions are even more fully digital today than mainstream Hollywood, with most productions never receiving any film footprint at any time, and as new prints become scarce, older prints deteriorate from age, and archival institutions focus more on digitizing them than risking damaging them further by projecting them.

As it seems to be six whole months ago when you released "How to Run a Projection Booth: The Basics" I am guessing that LNL is open / or they let you in the booth again. Dim wit here, of course, no audience! Nice to have you back!

You should consider adjusting your lenses so you don't have to refocus between flat & scope. Your mention that the manual advance knob can sheer off is spot on. I always used the motor flywheel to advance the film.

@KyleMiko

Thanks for the tip! And yeah there are not many flaws with the DP70, but using the flywheel is always the best way to advance!

At 2:05 you indicate the film turns counterclockwise at the top and clockwise at the bottom. This was standard in the US, but in Europe, both turned clockwise. This is because the US standard used an "S" form in rewinding, with counter-rotation reels, while Europeans used a direct over or direct under configuration, with both reels in the same direction. The reason this matters, is that the US "tradition" is in direct contradiction with the SMPTE Recommended Practice for "Emulsion-In" film handling, wherein films are stored on reels with the emulsion facing inward, toward the center of the reel, to avoid the stretching forces of facing the emulsion outward, causing crackling and other mechanical breakdown of the emulsion layer. The US set the standard, but neglected it, while the rest of the world followed it.

Merci pour vos explications. Nous ne faisons pas de cette manière pour charger un DP70. Il faut impérativement passer par l'entraînement denté supérieur. Ce dernier a notamment la fonction de protéger des sursauts de la bobine émettrice et surtout la fonction d'éviter toute vibrations du film dans la fenêtre de projection. 😉

@gregfaris6959

Жыл бұрын

Cette pratique est peu orthodoxe, et ne correspond pas au schéma de chargement du constructeur. En principe, le débiteur « F » fonctionne en tant que débiteur d’isolement pour le lecteur magnétique, et n’est utilisé que dans ce cas. Peut-il apporter une stabilisation accrue pour le film entrant dans la fenêtre de projection, comme vous le suggérez, si j’ai bien suivi ? La supposition serait d’autant plus convaincante s’il s’agissait d’un lecteur sonore (magnétique ou optique) où le défilement parfait du film est important. Il serait en effet concevable dans ce cas que les rebonds et autres oscillations de la bobine débitrice puissent se transmettre, si ce n’est que par le très léger « jeu » des perforations sur les dents. Dans le cas de la croix de malte, permettez-moi d’en douter, car les phénomènes vibratoires très violents induits par processus intermittent sont à des ordres de grandeur plus importants. Ceci appelle pourtant une autre observation plus générale sur les projecteurs Philips et Kinoton, qui n’utilisent pas de débiteur d’isolement APRES la croix, comme le font les projecteurs Américains. On peut douter de l’efficacité de cette « grande boucle » où la rigidité du film lui-même sert du seul amortissement avant son entrée dans le lecteur optique.

Very good but, too my mind your intermittent loop was too small, not in all cinemas do we come off the left hand side of the reel and you can run 35mm 4 track magnetic film through the mag penthouse. I have run DP70's in 4 cinemas here in the UK and I have a pair here at home which are totally original. There are difference's between the Norelco DP70 used in the USA and the Philips DP70 used in the rest of the world.

@KyleMiko

Our intermittent loop is actually correct based on our Kinoton sound reader! It changed the loop size as the loop is moved down

Your upper loop is 1-2 perfs too large. This isn't enough to damage the film, though. You also might want to make a point about not opening the gate until the machine has fully stopped, as doing so could potentially destroy the shutter (not a fun or cheap replacement). Otherwise, nice job.

@KyleMiko

Interesting, I was always taught that the upper loop should be in line with the circle object from the film gate. And yes, 100% agree should tell them not to open the gate until the DP70 has stopped. Sometime I forget what people don't know!

Random question, if anyone can help. My guys will project a 35mm film tomorrow, the aspect ratio is 1:1.66 (they always project 1.85 and 2.39 stuff) they will use the flat lens as would use if it was 1.85?

@KyleMiko

3 жыл бұрын

It’s probably too late but it most likely is a flat lens. The aspect ratio is more to do with the aperture plate, with the lenses being wether or not the film was filmed with an anamorphic lens. Easiest way to tell is if the picture looks distorted or not. If it is, it’s the wrong lens

@clickykbd

Жыл бұрын

@@KyleMiko I think it depends a bit on the theatre/screen/masking setup. If you try the 166 with a flat lens and the image spills onto unmovable masking (or masking that doesn't move far enough), then that aspect needs it's own lens. It will be more common with 133/137 which use the full height of the frame. Our theatre has movable top and sides, but we also have a curved proscenium arch. We have a lens for 133 but can get by with the flat lens for 166.
