@a1ex This is way beyond my league, hoping that you or g3gg0 could take a look if possible. Thanks!
Server moved to new hardware. Should be faster and is cheaper on top.

Yeah... unfortunately this is not supported by mlv_dump directly (MLV -> MLV).
What's wrong with exporting DNGs and just picking the needed ones?
Don't use 10x zoom.
Have tested with raw_rec.mo on the magiclantern-v2.3.NEXT.2014Feb16.5D2212 or just mlv_rec ?
did you try the latest nightly build , I think it's Feb/2018 ?
If you feel like living on the bleeding edge , maybe try this on the Highly Experimental raw_video_10bit_12bit_LVState-wip ? see Reply #681
caveat : only works in pure ISO's (100,200,400,800,1600,3200) All digital ISO (160,300,320,500, etc. ...) cause a Lockup/cam freeze , need's a battery pull to unlock.
If truly the frames are out of order at 1 fps then a1ex or g3gg0 are the ones that need to look at this , it's way above my pay grade
There a few different development ml builds I made for research in my bitbucket downloads you could try magiclantern-10bit_12bit_raw_twk_crop_rec.2016Dec01.5D2212 ,
magiclantern-Nightly.Compressed.Raw.Bit.Reduction.2017.May11.5D2212 or magiclantern-adtg_gui.2017Apr04.5D2212
there all work but have special tools to help in reverse engineering .
Edit: A light bulb just came on , does still happen if you don't ramp ISO or change it ? while filming -- I seem to remember something about back in 2013 on the old 5d2 thread.
Edit 2: RAW+FPS override=error every second frame reported in September 21, 2013
Question , why are you using "FastTV mode" ? you get better results with "exact" frame rate .
One last thing , is your cam set to "PAL" or "NTSC" ? I never tested if this issue is related to that -- I'm in NTSC land .
If you are recording1856x1044 @15fps why do you need to use mlv_lite ? There no advantage to use mlv_lite unless you are recording @ 23.976P for extended record time
(1856x928 23.976p is continuous) and if the reason is to have overlays/GD in full mlv (mlv_rec.mo) all you need to do is enable "Allow Global Draw" when recording mlv .
@mothaibaphoto - Use Davinci Resolve 12 beta, set it to use YRGB color managed (setting panel). Set input colorspace to linear, set workspace to ACES and output colorspace to linear (also in the main setting panel) then export half float .exr. This is a common professional compositing practice. If you want to work in another colorspace just change the workspace colorspace to something else i.e. sRGB/Rec709. The .exr file will retain the DR.
You can try FRSP in video mode. as far as I remember, it works, just not possible to set exposures longer than framerate.

This is known issue for STM lenses.
Canon 16-35mm f/2.8 L II works pretty well for me with FRSP.
