Dual ISO video recording

Hi

I wonder if video recordning using dual ISO only is supported on 5D Mark iii ? In that case, are there any plans for implementing it for other models?

It works in most models except 7D and 50D.

That sound good but I'm a bit confused because I have a 5D Mark ii with ML Nightly.2015Jan155D2212 and Raw and Dual Iso modules enabled and RAW Video set to ON and when I'm in Live View mode the Dual ISO is grayed out. However, if I exit Live View and go into still mode Dual ISO becomes white.

Is it possible to record video with dual ISO anyway? I don't get it to work.

sorry, it appears the 5D2 is unsupported as well

Too bad, it seems like a really nice feature, hope, you guys are able to implement it for 5D2 as well

I have same problem

I can shoot picture wit DUAL ISO, but when I run video mode (RAW mode is enabled) DUAL ISO is grayed out and write with red word: "(MOVIE) This feature requires you shooting RAW"
But RAW is enabled!!!
If there's someone who can solve this problem???

There's no macro that tells you if dual_iso works in video mode, so you can't really tell from the features page. You have to look at the source of modules/dual_iso.c and see if the registers are defined for the particular camera (it works in video mode if registers that start with 'FRAME_CMOS_ISO_XXX' are defined, otherwise the camera only supports still photo dual ISO). To port the feature, some dev with the camera needs to find the registers. More info here: http://www.magiclantern.fm/forum/index.php?topic=13597.0
