Hello all,
I'm a newbie to the forum so apologies if i ask a dumb question or repeat an earlier one.
Approaching 60 and getting sentimental, decided to unearth my 8mm projector. Planning to change lamp for an LED version, which I think is straightforward??
However I have seen some folk convert machines to telecine. I would like to do same.
I have a Canon 5D MkIII for the video bit, just need guidance on how to adapt projector.
Any help appreciated

Regards

Paul Bryan

Welcome to the Forum Paul!

There are several ways to do telecine depending on your equipment and technical skill level. Your expectation of final quality is also very important in determining which telecine process is best. There are loads of "How to telecine" posts on this forum and on the internet. I suggest you first do searches here and on Google.This will provide you with enough detailed information to experiment and we can help you with any specific questions and problems that might arise.

However, I can give you some feedback based on your initial post. The Sankyo 1000 is a good choice for realtime projection telecine. You can project onto a piece of white paper on the wall or onto a mirror and ground glass unit and capture the image with your camera. There are also telecine boxes that are simple to use and will allow capture without the room being darkened. I would try one or more of these methods initially to see if the quality is acceptable to you.

As far as the Sankyo 1000 is concerned the biggest advantage is that to do projection realtime telecine it doesn't require any modification. For projection realtime telecine the original lamp wattage is fine and it has variable speed control for synchronization. That's all you'll need. However there are some disadvantages that might make you look for another model projector.

1. LED conversion has been done... but it is not that straight forward in my opinion. It requires a separate power supply. There is someone on this forum selling a plugin LED system. Instead of the LED conversion you might just want to look for a Sankyo 2000H projector that has the brighter and more modern EFP bulb.

2. Frame by frame modifications have just not been successful with the Sankyo 1000 nor has recording directly off the film gate. It is just not practical with this machine since the lamp light doesn't go on until film is moving through the gate. This makes it very difficult to setup exposure and focus with your camera. And this technique definitely requires a very low light source.

These are just a couple of issues to consider. However there a several of us on the forum that can provide you help once you get started and specific issues come up.

Am I not right in thinking that if using LED conversion, lamp can be on independent of main projector switch, ie film could be stationary in gate as LED is cool running?
Ideally would like to link projector lens to camera to get better quality. I would use Cann5D MkIII in video mode and start recording when film starts running?
Sound not required as all my films are silent.
Was thinking of a daylight LED which is about 6,000-6,500k colour.
Am I looking at this too simplistically?

Paul, I indicated in my previous comment that a "separate" power supply would be needed for the LED lamp. If this is something you want to use then give it a try. DIY telecine is primarily trial and error and again depends upon the quality you seek. If you already have a setup in mind then go for it and let us know the results.

Hi Janice, Paul
I also have a Sankyo 1000 in reasonable condition (once repaired, I posted a different call for help elsewhere about the blown electrolytic inside that needs replacing...)
I have never tried "telecine" transferring, though I have all the gear-
what I am wondering about is the inevitable interference between the 16 (8mm) or 18 (S8) fps and the Video PAL 50 (or more, digital)?
How serious (or tolerable) is this?
Some video cameras allow variable frame shutter speeds- would that be helpful?
thanks for any comments from "the gurus" to a forum newbie...

By "interference" I'm assuming you mean "flicker" Hans. The Sankyo 1000 has a rheostat variable speed control. You just turn the knob until the flickering or banding disappears.
