Merging HDR Video
I’ve been shooting a lot of nature lately, and decided that I want to give HDR video a whirl. I’ve been thinking about the workflow and wanted to know how others would approach this.
1. Since HDR video shoots one frame under exposed and one frame over, when combining the HDR you end up cutting your frame rate in half. So if my target is 23.97 or 30i, I’d want to shoot the HDR at 60fps. On my Canon T3i that means stepping down to 720p. Meh.
2. Can I do this manually? I know GingerHDR is the official way to go with the Magic Lantern stuff, but they don’t offer any kind of trial, and I don’t want to drop $150 on something I may not be fond of. I mean, the idea of HDR video is tantalizing, especially for someone looking to make some dough on the side with wedding films. But if it doesn’t work to my expectation, that $150 can go toward some more tangible equipment.

From what I understand, Magic Lantern only needs two exposures; one for shadow, and one for highlights. I’m pretty sure it interlaces the footage to achieve this. I may not even need to shoot 60fps if that’s the case. I may be wrong. But it would explain why the example on Magic Lantern’s site has movement in it.

Hi,
I’m working on real estate videos and early this year I bought a slider with a motion system to use on timelapses.
Well I used this system to shot an interior area with windows ( so common problem, unless you use a camera with high dynamic range, making the proper exposure for the inside, the windows are burned )
and I recorded 2 automated shots. One exposure for the interior, and one for the windows.My problem now is: HOW (GOD HOW) can I blend these 2 shots, without going to After Effects, and make a mask for each window. This works, but needs lots and lots of time.
Any idea?
