Magic Lantern Ginger HDR Workflow

I suck at this but I thought I would share my mistakes.

Testimonial-1

First off I want to say I suck at this so far. Getting HDR video is not easy even though Luke Neumann makes it look so easy.

Any suggestions on how I can get better at this would be really appreciated!

I am including my workflow below even though my results suck so far so you can either make suggestions on what I did wrong or not repeat my mistakes.

I am all about sharing even if the results do not look that great. If I get a lot better at this I will make a new blog post on what I have learned.

Download what you need (T2i, 5D markII)

  1. Download the latest Magic Lantern
  2. Turn on advanced mode within ML,
  3. Download the Ginger HDR software
  4. Find a good HDR shot with lots of contrast.

Shoot HDR Video

  1. 30fps better than 24 at 1080, (more frames to use)
  2. 15fps so shutter at 1/30th of a second
  3. Make sure that on your lowest ISO setting that none of the blacks are going to clip, use the ‘percentage thingy’ around and move to something that is black, make it 5 percent.
  4. On your highest ISO setting make sure you can still see detail in the brightness part of the image.
  5. For some reason I did not have a good experience using the histogram for this.

Run GinderHDR Merge

  1. Open up GinderHDR Merge
  2. Find your movie clip (.mov)
  3. Locate the place you want the still images to go (call the folder ‘EXR’ or something)
  4. Merge type: Full Speed
  5. Optical Flow Resolution: Medium
  6. Fix Flipped ISO: ‘X’

From 19Lights (definitions):

The merge type is just whether you want to go half speed or full speed. So if you shot 1080p@30fps, and you want 30fps video, you would want “Full Speed”. If you shot at 720p@60fps but you only want to output at 30fps, you would pick half speed. Half speed will be much cleaner because it uses the Over frames as-is, and only blends the underexposed frames. Any data from the Overexposed frames is guaranteed to be clean.

After Effects

  1. Open up After Effects
  2. Import your footage. File -> Import -> File select 1st image your image EXR sequence folder
  3. Interpret footage, set to 15fps
  4. Change comp from 8bpc to 32bpc
  5. Drag your clip below to editing area.
  6. Effect -> 19Lights -> GinderHDR

Ginder Setting Workflow

  1. Open up all of them, and then check all the boxes
  2. Bring down the exposure until you see the highlights like you want them
  3. Two Level Merge -> Advanced, enable -> set the tonal ranges lots of black, gray where the highlights are and just a sliver of white -> disable that box
  4. Two level merge -> high and low strength
  5. Filmic Curve -> shoulder
  6. Filmic Curve -> Shoulder cut off
  7. Filmic Curve -> Midtones
  8. Filmic Curve -> Toe strength
  9. Local Adaptions -> strength try not to go above 1.5
  10. Local Adaptions -> details
  11. Filmic Curve -> Global contrast
  12. Local Adaptions ->  width
  13. Lens Filters -> saturation
  14. Filmic Curve -> Toe strength
  15. Filmic Curve -> toe cutoff

Render

  1. Composition -> add to render queue
  2. Find folder to render to
  3. no audio
