Forgive me for not reading through every single message possibly related to this.

I want to do the following:
• Use an Arduino controller to move stepper motors and pass 400-1200' of 3-4 perf film through a gate, illuminated with a RGBW LED lamp.
like this: https://www.magiclantern.fm/forum/index.php?topic=25117.msg228255

• Mirror Lockup to avoid vibration and keep it from flapping around

• Use the 5D as a film scanner at max (2-4) FPS — without triggering the DIGIC buffer overflow to shut down.

• I'd like to avoid the MLV format altogether, and instead pass the full CR2 raw file (5616 × 3744) data back to CF Card, preferably as a CDNG, but that's a big ask.

It seems this has been done in parts but not all at once. Am I missing something critical in the forum history?

Thanks in advance!

Since you're using an arduino already - would it work for you to have it trigger the lamp on/off per frame?  If you do that, you should be able to use Motion Detect.  The change in brightness will trigger it.  I'm not sure if you can combine FRSP and Motion Detect, but it's worth a test, if so you'll avoid mirror and shutter usage.
