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!

Raw Video / How to eliminate Vertical Stripes from DNGs?
« on: August 13, 2020, 05:40:37 PM »
I unfortunately have blown away dozens of MLVs, except for a choice few, and have found that MLV App's "Force Vertical Stripes" fix does wonders for that footage.

Is there a way to "re-wrap" my already exported DNGs+WAVs back into an MLV, then re process it through MLV App to eliminate the vertical stripes issue?

I filmed this panel discussion at the New School and am trying to figure out what the heck happened. Filmed with 3 cameras: BM Ursa 4.6K EF, BM Micro Cinema Camera, and Canon 5D MKIII running ML 1.2.3 to MLVs. I have already post converted the MLVs into DNG sequences. Camera was set to 1920x1038, 24 FPS and was not set to FPS override or off-speed recording.

When bringing the files in, the audio is consistently 20-30% shorter, even if the footage reinterpreted to 29.97.
Every other thread I read, people say their audio is *longer*, but mine is quite the opposite.

Let me know if you have any thoughts. Here are a few clips exhibiting these symptoms that I'm trying to ... resolve. ;)

Raw Video / recording + previewing ML Raw video via DJI Lightbridge 2?
« on: January 01, 2016, 10:08:54 PM »
I'm about to dive into the world of UAV / drones and want to fly my 5D MKIII on a DJI Spreading Wings S1000+ with a DJI Ronin-M [why? because with a CineMilled plate I can use one gimbal for handheld and drone work] and control my flight path via DJI Lightbridge 2 + A2 controller.

I noticed that martinbennett70 used ML Raw when shooting his piece for Overfinch

There are numerous slow motion drone shots and I would love to know how would you monitor and start recording via DJI Lightbridge 2 and the OSD Android / iOS App, but my experience with using an external HDMI monitor while recording with ML Raw / MLV and a firmware of 1.2.3 creates a lot of lag, potentially corrupting the files we're recording while a camera is 400' in the air. I would hate to hose the shot because I was recording at a overcranked frame rate, running out of buffer space and having it drop frames or unexpectedly terminate the recording.

Any experience or links to other relevant threads would be greatly appreciated.
