iPhone X 16mm film direct transfer

[Stan Jelavic]

Set the phone shutter to 72 FPS. Then adjust the ISO for required brightness. I have a 100 ohm potentiometer in series with the LED and use it to turn the brightness down if there is a bright spot in the center of the screen. There is no flicker and almost ghosting free.

Thanks Stan, what are the details on the shutter speed for the phone? Does the MoviePro app stop flickering?

[Stan Jelavic]

Haha like the comments. Here is some more info:
- projector Elmo 16CL running 24FPS
- used MoviePro app. Operating instructions available here https://github.com/vintagefilmograph...16CL_to_iPhone
- used the HDMI dongle https://www.amazon.com/dp/B0BVM84Z6H with audio input
- Modified the projector by adding an LED light and charger, brought audio out. TRRS cable and attenuator also required.
- Did a horizontal flip (around horizontal axis) in the app itself but the video needs to be flipped vertically in the post (have not done any postprocessing)
Not bad results. I also developed a macro lens for the iPhone and will run the resolution tests.
This video is without the macro lens.
This can be a solution for people that do not want to spend a bundle of money and already have an iPhone.

That is a USB-C breakout adaptor that allows you to connect and HDMI monitor or audio speakers to your phone. The white cable going off to the side is a power supply and the coiled cable is his audio from the projector. It is reversed because he is filming directly into the projector. Remember a projector lens inverts the image. It looks really good considering it was shot on an Evil Fruit Empire Product. lol

The white box is most likely an adapter to record audio from the projector while simultaneously recharging the iPhone:

(The one from Walmart only has got a combined socket for audio in/out - the one used by Stan most likely has separated sockets.)

I don't understand why it's a reverse image or mirror image on the second video

[Alwyn Adkins]

Not bad, not bad at all!

Now for the juicy stuff:

Stock iphone camera app?

iphone shutter speed?

Any particular iphone modes?

What's the white box hanging off the iphone?

Projector running at 24fps?

Here is the transfer setup.

And here is the resulting video:

Used stock Elmo 16CL. The only mods are new LED light and the sound jack added on the top of the unit plus the LED brightness control.
