An introduction to some work I've been doing with Super 8 movie cameras, creating a digital cartridge with a Raspberry Pi.
At the end I talk about something else I'm involved in. Trans Rescue is a small non-profit that gets trans people out of dangerous places. At time of upload we have an appeal, we have a passenger stuck for whom we need to raise cash for a flight. Please click on the following link for more details, and give us your support. transrescue.or...

Thoroughly enjoyed this Jenny- no idea how the algorithms sent this to me, but I’ve just bought two super 8 cameras, so maybe that’s why. I’d love to be able to have the choice of shooting film and digital on them both. Good luck with the project 👏🏻

I just had a sneaky idea how to trigger the record function on the Rapsi: Point a LDR or photodiode at the little screen you're planning to shoot the back of, as there should only be light entering the film gate when the Super-8 camera is actuating its shutter and there should be enough light scattering into the space inside your digital cartridge to pick up.

Love this project. No doubt I'll spend the evening on eBay looking at super8 cameras. Maybe the carrier could be adjustable with a couple of screws accessible from inside the cartridge. Left/right forward/back to tune the focus?
@jennylist
@jennylist Год назад
Thanks :) Always worth looking at second hand shops, so many online sellers seem to think they're made of platinum and very rare (They aren't). The carrier is adhustable with a couple of screws on slides. It's not perfect. The real problem is the film gate assembly.

Why don't you take off the UV-lens, from the picture-sensor? That will make the sensor less thick. Then add an 'after-market' UV- lens onto the outer objektive. This should work, you will get this one Millimeter off, you needed for proper projection of the images. The quality of the video you will get, should be like 'with the UV-filter' again. Hope you can finish your project. Sorry for my bad English, it's not my native toung, ... ! Greeting from Germany, Markus (db9pz) - my Ham radio call
@jennylist
@jennylist 10 месяцев назад
Imagine the sensor as a glass box a few mm thick, with the light sensitive chip on its back wall. The UV filter isn't the issue but those few mm, they're enough to put the sensor outside the focal plane.

funny i saw your Single-8 video first and then the part 2 of this series and now this one ... 🙂anyhoots, if the tiny size of the video sensor is too hard to fit within the camera's gate exactly, then why not use a slightly bigger sensor that would fill up not only the entire gate area, but also go further around it to make sure at least part of the sensor fills up the gate fully!? i know already this could not be the perfect solution but it might be a good new starting point? after all, some DSLR cameras already use this little trick for a number of reasons ...
@dadautube
@dadautube Год назад
btw, the time length of the Super-8 cartridge is not 5' ... it's 2.5' when shot at 24FPS and more than 3' if shot at 18FPS ... 🙂
@dadautube
@dadautube Год назад
i'm also thinking that extra empty space in the digital cartridge can be used for quite a number of things ... 1stly, sound recording circuitry can be installed there ... or extra battery to run more power-hungry micro computers and sensors and so on ...
@jennylist
@jennylist Год назад
The real problem is getting the sensor in the focal plane. It's surprising how much difference as little as a milimetre makes.
@jennylist
@jennylist Год назад
The intent is to replicate a silent cartridge, and let the filmmaker record their own sound. Sound recording in the cartridge is problematic, often there's no way to get the audio signal into the camera.
@dadautube
@dadautube Год назад
@@jennylist yes i know about that ... but as you have demonstrated that yourself too, the slight adjustment to the lens trick that works but also turns it into a macro lens instead of a 'normal' one, can now be applied to the sensor itself, by means of some screw / volume thing moving a tiny plate holding the sensor back and forth for fine tuning its distance from the gate ... after all, with some output signal taken directly from the sensor cartridge, its image can also be viewed on a separate monitor outside the camera's cartridge chamber, right? 🙂

Now it would be nice If Sony could develop a camera sensor module that would fit within the film gate. It would make our lives a bit easier, even if some Chinese company would make a camera sensor to fit it would be great!
@spacemansabs
@spacemansabs 10 месяцев назад
if you make the sensor mounted in a way that you can put sheets of paper below it, you can use them to micro adjust the distance. A sheet of paper is 0.1mm thick which is probably the closest you will get in tolerances anyway out of a 3D printer. It might help you dial it in. :)
@jennylist
@jennylist 10 месяцев назад
The original sensor mounting in this video wouldn't be helped by this, but I am using exactly this technique with the latest lens mount.

I know you make millions and millions of dollars doing such a business like this even for many independent film studios using Super 8 film cameras. Think of all the great movies they might make.
@jennylist
@jennylist Год назад
I don't think for an instant that such a business would be successful,. There has been no volume production of Super 8 cameras in many decades, and meanwhile a reasonably good quality modern camera such as a mirror less compact can be had for only a few hundred dollars. The value of Super 8 for film makers lies in the properties of the film itself, which this doesn't replicate. Also there is a mystique about working with real film for them, which this cartridge can't possibly replace.
