HDR: How To Make Real World Look Like CGI
via vimeo:
HDR Video Demonstration Using Two Canon 5D mark II's
This video highlights several clips we've made using our new High Dynamic Range (HDR) process. Video is captured on two Canon 5D mark II DSLRs, each capturing the exact same subject via a beam splitter. The cameras are configured so that they record different exposure values, e.g., one camera is overexposed, the other underexposed. After the footage has been recorded, we use a variety of HDR processing tools to combine the video from the two cameras, yielding the clips you see above.
HDR Video provides filmmakers with many exciting new opportunities. Not only can HDR video create interesting effects, it can also allow for even exposure where artificial lighting is unavailable or impractical. For example, when a subject is backlit, one camera could be set to properly expose the subject, the other the sky, resulting in video with perfect exposure throughout.
We will continue to develop and improve the HDR video process for better results and efficiency. For more information, check out our website sovietmontage.com.

well the difference is that this is filmed in real time and not in some timelapse mode.
Though it's still not really HDR(the images doesn't differ enough), but rather just tone mapped which is normally mistaken for HDR.
And they really effed that one up too as they use way to much of it.
RaaaghLooks gross, but im sure there are real world applications that look good.
xxovercastxxThis is a bit half-assed.
First, you should combine at least 3 exposures, 4 or 5 preferred, to get a fuller range.
Second, you should reduce the contrast afterward to get a natural appearance.
The whole idea with HDR is to replicate the process of viewing things with the naked eye. When you look at something bright, your pupils contract, cutting the light and allowing you to see details. When you look at something dark, your pupils expand, allowing in sufficient light for you to see details. A scene shot with a camera (still or video) normally has one exposure, so details in the darker or brighter areas of the photo are lost. HDR is meant to provide optimal exposure for all areas of the photo and, done properly, looks incredibly natural.
I wonder if @youdiejoe has anything insightful to say about this?

It's a fun first attempt, but in the end it just looks like poor HDR photography. I imagine that when the process does work it will be a single camera, single lens affair with the CMOS sensor being the one doing the neat tricks to make the HDR images.
