Red Cine X - HDRx workflow

[Adam Griffith]

Calling on the experts as I'm wasting huge amounts of time and I'm sure there is an easier way.

I have a few HDRx clips, I'm bringing them into Red Cine-x and tweaking the A track and X track individually (just basic exposure adjustment) then exporting them out to a TIFF or JPEG sequence.
I then combine these in a 3rd party app (photomatix) to get the HDR look I'm after.

Currently the only way I can work out how to do this is by adding the A track to the timeline, adjust exposure then export timeline to a TIFF sequence and then renaming ever file with another app to have "A" suffix
Then clear timeline and repeat process with the X track and change file names to have an "X" suffix.

Surely there is a way to just select the single R3D clip and export both A and X tracks as TIFF sequence with a single option? Maybe it can even name them with the track suffix (A or X) which makes combining later in Photomatix easier/faster.

I'm sure there is a simpler and faster way than what I'm doing right now. I havn't been able to work it out without adding individual tracks to the timeline first.

I'm trying to shoot hotel rooms without having to apply ND film to all the windows which is what was previously done (an ARRI Mini was used) but I think I can save hours of time on the shoots by using the Dragon and HDRx
This is the look we're trying to arrive at (not my video): http://www.youtube.com/watch?v=pI8SxGt_YTg

Thanks in advance for any tips on this. My current workflow means I wont finish the project for months!

You are on the right track, set wb and iso in redcinex, then export A and X track to 16b TIFFs utilizing redlogfilm, then use "bulk rename" to number them odd and even, process, them bring into after effects, utilize the Adobe RAW trick and process accordingly, then either export as prores or utilize dynamic link.

You can buy a polar ND filter and not shoot in HDR.

Thanks Andrew. I was just hoping there was a simpler way or that Cine-X had the effect that Photomatix had.

Thanks again


Aaron, I may misunderstand what you mean but wouldn't an ND filter reduce the exposure of the whole frame? I was to knock the windows down 1 to 3 stops but retain a correct exposure within the room itself.
We've tried over-lighting the room to compensate but didn't really work that well.

I have done exactly like you have Adam, using Photomatix ! And yes, it seemed like an awful lot of trouble, there should be a simpler way I agree

Oh well. Didn't think it'd hurt to ask around. I guess I'll get more efficient at it the more I do.

Do you find you get a lot of flicker in the end result from Photomatix? I'm not sure how to eliminate it entirely, its very distracting.

I think combining them directly with the R3D originals in Resolve is infinitely easier and more practical. It's possible to only combine the images that actually need the additional exposure room using windows and keys (all covered in the Resolve manual).

 

[Andrew Allsbury]

Yes, if nothing or no one are in front of the windows, there are easier ways to.blend the tracks utilizing just ae or ppro. However if you want the full hdr effect, Photomatix is a must. As far as twitching goes, stay away from tone mapping and use the other option whose name espaces me at the moment, that will result in almost no flicker, any that's left can be taken out with RE:vision de-flicker.

I just made a tutorial on this if you guys want. I personally don't find the process that long, but I do agree that it should be a option in RedCine-X.
