@dmilligan: is your deflickering script works too with the older ACR process version (2010)? I would like to get back shadows and recover highlights detail in my timelapse (sunny, cloudy, sunny, cloudy) with the fill light and recovery sliders. I read somewhere that it doesn't produces so kind of flickering troubles as the touching of the shadows, highlights, blacks, whites, etc. sliders in the new ACR process version (2012).

... or somebody knows a workflow for getting back shadows and recover highlights without additional flickering?

I thought I'd compile some of the advice that helped me get my head around this:

Thanks for doing this!

ok, so im sure somewhere in here people have mentioned this, or hopefully (fingers crossed!) found a solution to this.

So im using this ramp script for a timelapse, and have adjusted the start, end, and set keyframes by using the star method, but when i go to ramp all, it takes care of everything except ramping Clarity..... I noticed there was a setting for ramp clarity 2012 but nothing really else, is that it? or am i missing something here?

basically im trying to take a bunch of camera raw adjustments, set it, then adjust all on out point (and any changes inbetween) then click go. not getting certain values changing right...

when i go to ramp all
There is no "ramp all" option in this script. There is a "Ramp Multiple..." which should pop up a window with a whole bunch of checkboxes that let you select which ACR settings to ramp.

I noticed there was a setting for ramp clarity 2012 but nothing really else
huh?

It's not very clear to me what you are talking about, so could you be more precise/exact with your words and/or provide screenshots of what you are doing/seeing?

I guess i dident explain that well... I see all the settings, and i check them all, it seems to only adjust some... attached are 3 screens, the first 2 with the first and second files, which you can see the clarity does not get ramped... as well as exposure.... and the last image is what im trying to ramp to (with a couple files marked as keyframs to account for lighting when sun drops)

none of the links work, make sure you get a "public" link, and the img tag dosen't work with https (only http)

I updated all the links above, instead of adding more posts... Really hope you can help me wrap my brain around this...

So, I have been using this script, but recently I started to have problems with large time lapses, where I have more than 250 frames, I do usually.

first - even tough this script is supposed to wait till bridge regenerates preview - it does not, at least when there are a lot of frames. So having 3 iterations on row is pointless - first one works, rest of them results are unpredictable. at least in my case, I had to run 3-4 times, each time purging cash my self and waiting till bridge rebuilds it. to get decent result

second - script eats up memory, when i have my 900 something shots, and when an iteration is finished, my 6GB RAM is full with bridge, and it gets freed only when I restart bridge. And if I don't restart and run next iteration - it can lead to extensive swap file usage - read - it makes slow script even slower. I'm not a pro programmer (tough I have written scripts for AfterEffects, InDesign, PHP, AVR ASM, Arduino) but for me it seams that variables, get created and information stored in ram but they do not get cleaned and unset when not used - there for eventually you would run out of memory.

but thanks for the script - in all grate tool!

I just wanted to give a thank you for this script, as well as for ML in general.  I just downloaded this a couple days ago, and made my first timelapse video.

Thanks!

I'm working on porting this script to Lightroom. As of Lightroom 6, the SDK now has basically all the necessary functions needed. Here's the start: https://github.com/davidmilligan/LrDeflick

Thanks, David!

Just downloaded and will test it out on LR5 since that's all I have atm.

Question -- is this where I can get djpeg utility from libjpeg?

Seems I'm having trouble to get it compiled and running.

Is this specifically for LR6 or can still be used on earlier versions?

LR6 only. LR5 API does not have the requisite functions.

@classicbs

Nice work! 

What theory did you go with when selecting a "Percentile" for the day to night transition?

At the beginning, do you want the percentile to be in the highlights or shadows?  And how far in the HL or SH?  In my sunset time lapses, I'm not finding a common ground because the I think the the 'red dots' of the percentile shift to an unreadable section of the image as it gets darker.  I've run Bridge, over night, with 300 iterations and still don't get a deflickered TL.  I have tried a low percentile like 0.20 and a high one like 0.90.  Love to hear your wisdom about this. 

Also, did you find an Analysis Size, Crop, Width, Height that produced better results?

I need to try your VisionLog suggestion next. 

Here's the 'red dot' I am referring to for those who might wonder. 
These images show 0.20, 0.70 and 0.90.

Percentile shouldn't matter much, just stick with using the median (0.5), I've considered removing this option altogether, b/c it doesn't really make much difference. The red highlights are just showing you where in the image that percentile is, but the entire image effects the percentile level, so it's not like that's the only area where it's doing the deflickering.

Something that might actually help would be to consider breaking the deflicker into shorter segments using keyframes (one star rating marks a keyframes).

please do not remove it, it is useful. It could be optional. I'll try to explain why - I had shot time lapse with radio telescope and partly clouded sky, the thing is that telescope brightness flickered, but sky did not as much, with the percentile I was able to make one or the other without flicker. here is sample with first iteration of .5 median deflickering:

finding deflicker creating wildly flickery results on a sequence shot in aperture priority auto.  Also is the preview supposed to show the percentile within bridge?  If so mine doesn't.  Could these things be related?  (i'm using a a value of .6 for the percentile).
