Hi everybody,

I was wondering, is there a way to make sd video (shot with 3ccd true color) into hdr video? I saw some great hdr photos out there and i was wodering if video could get that awsome. I saw some great examples on the topaz website.

HDR photos are created by shooting at different f-stops and combining them in Photoshop. You cannot do that in video. Nothing will move the same way for the second take. You could, however, do a stop motion video by taking a bunch of HDR photos and making a sequence out of them. The new HDR features of Photoshop CS5 would help a lot in automating that task.

"...You cannot do that in video..."

Not intending to be disrespectful, but a member of the Stereoscopic 3D Cow Forum seems to have done it on video before, and in 3D too -

PS: Apologies my error. It was NOT shot in 3D, he just used a 3D rig to shoot the HDR, and post processed with CS4/5.

[Thomas Leong] "...a member of the Stereoscopic 3D Cow Forum seems to have done it on video before..."

...and you will ALSO note that the only thing moving in the shot is the camera. That's very significant. I didn't see a breeze moving the leaves. I didn't see any complicated camera move. This was a shot easily repeated using Motion Control... which is something they fail to mention.

Now, if YOU have a motion control rig -- they're only about $35,00 US -- and YOU want to shoot still lifes only, you too can do HDR in video. If you do anything else, it gets prohibitively complicated.

Sorry, I should have mentioned that you could do it with a motion control rig assuming nothing in the shot (leaves, etc.) are moving. I sorta mentioned that, but didn't specifically say it.

I should also mention that you can do it if you have a prism-type lens thing that would duplicate the light coming through a lens into two or three other lenses attached to cameras at different settings.

You could kinda do it with a stereoscopic rig, but you would have to deal with the fact that the two images are slightly misaligned from one another.

[Thomas Leong] "His last post in June is all motion, people motion that is -"

Uh-huh. And did you bother to read just HOW this was shot? Here's the description from Vimeo:

"Shot on 2 Red One's without MX upgrade with the OmniRig using 2 Ruby 14-24 zooms at 16mm with no geometric or lens fix in post. Tone mapping done in AE CS5 32bit project, added a little saturation on the HDR. This was shot at about noon with no lights or bounce, it was almost impossible to see into the shadows with our eyes as it was so bright out."

To summarize:
  • The guy used identical cameras, the quality of which most of us only dream about.
  • Except for the exposure, the two cameras were getting the identical shot.
  • The AE work was done at 32 bit, which has a LOT more exposure latitude.



There's no magic going on here. Professional photographers using professional gear, who had planned out what they wanted to shoot, and who knew how to manipulate their images properly in AE, were able to pull off an HDR effect. Duh.

It's not the kind of thing you do with an HDV camera and other prosumer gear and hoping for the best.

As others have mentioned, you can't make true HDR from your existing footage -- but if you like the Topaz Adjust look, I think you could fake it with Photoshop Extended and the Topaz plugin.

Open your video in Photoshop, convert it to a smart object, apply your filter, then File > Export > Render video.

Restores highlights and shadows for hd'ry look
Saturation that works like photoshop's vibrance
Local contrast that works like Topaz adjust

Cherlique,

There is nothing presently available for SD Video other than the possible workarounds pointed out by the others.

Spheron has a functional HDR Video Camera in the works for full HD resolution with 20 f-stops of dynamic range, but not released to market yet.
A bit more news about the Spheron HDR camera is available at http://www.hdrlabs.com/news/index.php

Darn it, Walter; I was going to link to that!
That's what I get for going out to see Scott Pilgrim vs. The World (again) last night instead of posting on the forums.

Ha! My wife is a photographer, and she showed me the video last night. I immediately ran for my laptop. I knew I had to post it right away before you got to it!
