I got the new drivetrain working. There are three separate motors, each with its own PID loop for feedback. I got both the motor model and PID loops in general from this very forum. Grateful to have you all here and helping me keep this project alive!
Please post any feedback or questions about what you see in the video here. There’s a lot more to be done, like the startup and end sequence. There’s also some error with the capstan motor that sends it spinning really fast if the film slips. Also, the film slips! Not sure if it’s because I don’t have enough tension, or it’s just the surface of this matte-finish PTR that isn’t sticky enough. Suggestions welcome.
Hi Matthew,
That film is moving pretty fast. Is that the speed at which you will be able to scan? I’m very impressed.I purchased a film gate that I will use for my Kinograph. I posted some photos on the Forum. I am leaning towards a single frame capture machine at this point. One thing I have noticed in the forums people comment that the DIY machines won’t be good enough for archival work. I disagree, it would seem that once the film mechanism is perfected then professional results could be attainable with better cameras and optics.

Hi Rob. I’m hoping to scan at 24fps. Fingers crossed! The final speed will be determined by the camera and processing capabilities of the hard drive it’s writing to.
I disagree with them re: archival too! It’s all a matter of what you’re going for. Digitizing is never a permanent solution no matter how high the resolution.
Kinograph is meant to be upgradable, as you point out. 4K camera? Sure! Add it on! That’s the beauty of open source!
Glad you found us. Looking forward to checking out your photos (I’m catching up on posts today).
@matthewepler is that 24fps telecine or intermittent capture?
I was trying to do some research on the fastest scanner out there, and there wasn’t any information easily available. I saw up to 100 fps, but I’m not certain how that is related to capture quality.
Do you know what is currently the fastest scan available @ 4k?
