Dual ISO down: Simple problem must have simple answer

[ivannoel]

'Sup guys.

Got to shoot a scene from inside a school looking out the window and all needs to be properly exposed.
Dual ISO to the rescue!

But not.
For some reason, I have spent hours trying to fathom, Dual Iso option remains disabled, saying I should be in RAW mode (which I am).
Any help welcome, as shoot is in 24h!

Thanks!

Code doesn't lie because it's bored.  Make sure you are in raw mode!

What camera?

You need to be shooting raw video, so the raw_rec module has to be on, or mlv_rec.
And then if that's still not working, try changing (in video mode) the picture quality you are shooting to RAW.

I never actually shot raw video, but I thought I read somewhere that sRaw won't work, fyi.

+1 on the sRAW not working, engardeknave. Had to be in RAW
