DIY Telecine

Hey guys,

I've been doing some reading on these boards and it seems that while it's been discussed, no one's come forward with a DIY telecine for 16mm film.

I was thinking I could score a cheap Krasnogorsk k3 from ebay, along with a projector, and use the same principles of a DIY adapter to get the best possible telecine with a DVX at the recording end.

For those of you guys that have worked extensively with film and the DVX before, do you think adjusting the shutter speed on the DVX would get rid of the projector's flickering? If not, would buying and installing those 5 blade shutters from eBay into a projector do the trick?

I want to work more with film, and I don't feel like we get enough hands on at school. If this is something that could be done with good results, it'd make it that much more accessible cost-wise for me to practice my shooting and cinematography. Plus, with a decent home brew telecine, one could even take an hd camera, plug it into the other end and have yourself an hd transfer to play with!

Anyhow, thanks in advance for any advice and insight you guys can offer.
 
Look at what these people do:

They use a rig that captures an aerial image in stead of an image projected onto a screen. While an aerial image won't work with a DOF adapter, it would work well for DIY telecine. You just have to get the optics right.

There was also some talk on the CML of somone trying to rig a flatbed scanner with a film gate to do automated film scanning...
 
one would think it could be done pretty easy, not a single frame by single frame,

in many ways all a 35mm adapter is a telicine with out the film. you would really have to had a synk camera, the k3, and most bolex's aren't. so the frame rate is never exact, one second, its 24, then its 22 then 26 and so on.
 
Frame syncing would be your biggest problem if you ran at full speed.

It might be better to use a digital camera instead of a DVX / camcorder. The original Canon Digital Rebel can be had for like $300, and you could set it in bulb mode, flash a frame, increment, repeat. Most of these cameras have a direct to computer output capability, so the images could go straight to hard disk. The camera to computer link would be your bottleneck; you might have to go as slow as a frame / second. As a bonus the imager in a good digital SLR will produce much better images than a video camera as a single frame imager does not have to cope with creating a stream of content. Even a first gen Digital Rebel would produce better images than a HVX.

They also have a wired remote button that you could use to trigger the next frame on the camera. The trick would be to control the projector. You would place a sensor on the projector's gate, condition the signal, and wire it into the camera's remote jack. Again, you would have to re engineer the projector to run slow so the camera could keep up with it.

It would be a cool project, but it will require both mechanical and electrical engineering skills to pull it off.

Yep, you can do it with your DVX, its quite easy.
Remember the function "syncro scan"??
Well, turn your shutter ON, in the position that has the editable number
If you don't remember which number, go into
MENU/CAMERA SETUP
There is the function SYNCRO SCAN, check the number and go back and make shure it is selected and the shutter is ON

Point your camera towards the screen that flicks....there yet??.. ok, now
Go back into MENU/CAMERA SETUP/SYNCRO SCAN
start changing the number until you stop noticing the flicker.

That's it!! works also for computer screens, TVs and flourecent lights

Good luck
