5d3 4k dual iso music video

[70MM13]

i got gain reduction working with dual iso at last...

no noise reduction of any kind.  check out the dynamic range and clean shadows!

shot at TNT iso 100/1600

fun coincidence:  the old footage from my film that is interspersed was shot by me 10 years ago this month using magic lantern on my old 550d!
i originally produced this song back in 1989 and it was a nightclub hit around the world.  it was fun to redo it after all these years.

watch in 4k!

Looks very clean! Can you share what ML build and menu settings you used? Did you use 4K anamorphic + dual iso?

When I recently tried to use dual iso, the live view screen has wide horizontal color bands (maybe this is normal...not a big deal). Then in MLV App, with dual-iso turned on, the footage looks pixelated/low-res with posterized colors (i.e. as if the image is made from only a few colors). Sometimes it looks normal in MLV App, but it will still output with bad colors and low res.

sometimes the "vertical stripes" function in mlvapp can generate some strange side effects in dual iso footage.  you might want to check that...

if you are interested in how i am optimizing the preamps, look around on my youtube channel for the "how-to" videos.  there's a few.  i might do a new one for dual iso if anyone wants it.

here's a file with comparison dual iso DNG frames with default settings and with optimization:
