The 70D has a sensor where each pixel is a combination of two pixels, a dual pixel system for autofocus.

The idea is to use the 70D dual pixel system to enable two different iso exposure in each pixel and merge the two exposures in camera or in computer to get HDR video. Similar to the 5d3 dual iso in raw, but using the 70d dual pixel in H264 MOV instead of 5d3 sensor lines in RAW for the different iso.

This would solve the motion problem from the hdr video using different iso in subsequent frames and would solve the aliasing problem from hdr video using different iso in lines.

Maybe Canon will do this in future?... ML team could do early...

Would be brilliant if it could actually be done. And it could I think, but not likely with a FW hack. Will prob have to come from Canon.
