Hi there, I am an experienced timelapser but new to LRT. I have recently shot sunset sequences using QDSLR resulting in the typical stepped curve.
After setting keyframes and hitting the Holy Grail Wizard I get the corresponding curve. So far so good and I don't change any of the settings. Save the metadata, take it into Lightroom (latest CC version). As a test I simply drop the exposure on keyframe 1 and use Lightroom script to copy the change to other keyframes. Go back to grid view select all frames and save metadata.
Reload in LRT click autotransition and save. The visual preview shows there are still large changes where the steps were.
The preview lum and visual lum values are pretty much the same with a large change at the step point even though the deflicker correction looks like it is working OK.
Preview Visual HG Lum level Deflicker
15 0.419 0.415 -0.122 0.024
16 0.417 0.414 -0.110 0.027
17 0.414 0.411 -0.108 0.030
18 0.412 0.409 -0.106 0.033
19 0.410 0.408 -0.104 0.035
20 0.452 0.449 Step -0.188 -0.021
21 0.451 0.447 -0.184 -0.019
22 0.450 0.446 -0.181 -0.017
I would expect the Holy Grail Wizard to smooth this step out before the Visual deflicker stage. So I try the deflicker stage and the steps are still apparant no matter how I set these up. I can add a lot of deflicker (smooth curve) and the Visual Lum figures do not change.
Am I wrong in thinking that the Holy Grail Wizard stage corrects the steps? Does it just flag them up? When stage are the steps mean to be smoothed out. I looked at Gunters video and the smooth stepping of the Visual Lum only appears after the Visual deflicker stage but mine does not.
Appreciate the help.
