MLraw, liveview not correct unless using native ISO of 160, 320, 640, 1250, or

I've heard that RAW only records in the native ISO levels, 160, 320, 640, 1250, or 2500

But canon h.264 will record in the inbetween non-native ISO levels by applying gain. So if you have an 1000 ISO, you are recroding at a native 640 ISO with gain added. And this added gain is shown in the liveview, making the LCD look brighter then the native ISO.

This means in RAW recording,  unless you are using a native ISO,  the liveview is actually .5 to 1 stops hotter then the RAW footage, or, your recording is going to be darker then the liveview?

you are correct, raw only records native iso, which is 100,200,400,800,and 1600.   

80,160,320,640, and 1250 are made with negative digital gain, so don't use those for raw. However, these are the ones that give less noise with h264 so DO use them for h264.
