I did some tests with GH2 and T3i 600D to see what is possible to do to increase dynamic range. The exposure stops was measured by camera meter and exposure compensation graphics in LCD with the camera pointed to the grass in the shadow.

The GH2 with 128Mbps GOP3 and a good denoise with neatvideo give these results:

Good quality image when lifting 3 stops underexposed image without idynamic

Good quality image when lifting 4 stops underexposed image with idynamic

This is enough for most situations, including clouds in blue sky with foliage and people under the shadow

The T31 600D in MOV (1.3x CBR = 7.1MBps), HDR and RAW and a good denoise with neatvideo give these results:

Good quality image when lifting 3 stops underexposed image in MOV

Good quality image when lifting 5 stops underexposed image in HDR (lifting done in camera by two iso exposures in HDR video function)

Good quality image when lifting 5 stops underexposed image in RAW

RAW is more powerfull but MOV and MTS are very good if the datarate is high.
