Hello from France,

You can have a look at this short experimentation : HDR video with Magic Lantern 2.3

I will post new exemples next week :
> Hdr videos with dialogues, sync (shot in 60p).
> Hdr shoot by night, somebody next to a very intense / strong light

1) Shoot in 24P
2) Output and master of the TiFF image sequence in VirtualDub :  in a non compressed file = RGB/CbYcbcr
3) Sony Vegas Pro11 : gradding only, and smooth sharpening (cause Picture Style Flat !)

Lens : Canon 28mm f;1.8
Picture Style : technicolor Cinestyle

Using HDR gives you the opportunity to shoot somebody in front of the sun or a window with good exposer on all frame, or in a dark room with a window open in the back during a very sunny day... (My exemples in my video)
Its just impossible to have a good exposure with 2 big different apperture in the same scene with a Canon...

Its not the case with a Red camera, or an ARRi Alexa, or a Black Magic Design Camera, cause they have more than 10 stops of dynamic range !

Is it clear for you ?
My English is poor...

It's possible to make HDR video with Sony Vegas Pro, cause all the tools are there :
1) Built the bright and drak frames (I can do it in Vegas)
2) Make 2 sequence of images in Jpeg or Tiff  = a bright and a dark one (I can do it in Vegas)
3) Merge the 2 clips (dark and bright one) >>> I dont know how to merge and tune the effects (Overlay, B&W mask ?)...after hundreds of try !!!!!

I've seen a tuto in english on youtube but impossible to understand it... My poor english

You need to use a luminance mask (derived from the over exposed image) to merge the frames together. Use this luminance image (over exposed image without color) in a key effect.
But there will be an issue at the blended edge between the dark areas and the light areas.
