How do you create a time-lapse on darktable?


(Mike) #1

Is it possible, or do you use another software in conjunction with DT?
Suppose you’ve taken a considerable number of still images on a tripod and want to create a time-lapse from that collection, how would you do it? Thanks!

It us not possible to create a timelaps using only darktable.

I’d edit the raw files in darktable, export each file, then use your favorite video editor or command line utility to actually create the time lapse.

If you’re comfortable on the command line, ffmpg is perfect for this:

There is although I’ve never used it.

Personally, I’d use DT to process the stills, then use slowmoVideo to do the actual time-lapse. (Although I’ve not used it for time-lapse, I’ve used slowmoVideo to process video files, and loved it.)

How do you create a time-lapse on darktable?

Darktable doesn’t have a time-lapse tool. I wrote some years ago a script to export selected images as a video. But I don’t really use this script, it is not flexible enough.

And here is a video I created with the help of dt some years ago:

Perhaps @devernay the natron guru can help here.

Thanks @paperdigits I’ll give #ffmpg a try!
Thank you @Karl & @Tobias for your input :slight_smile:

What do you mean with this code, and where do you plan to past it?


Very interesting! Many Lr user miss video feature in DT, any plans in the future?

(Mica) #9

I’d think video features are way out of scope for darktable.


What would be recommend? Natron?

(Mica) #11

Depends on what you want to do, exactly. FFMPG will stitch all your images and output a movie. There are also many graphical editors, such as open shot and kdenlive.

What I would like to see indt is method to set the parameters of the first and last image and then interpolate between them.


There is a darktable fork on github that adds a ui for these timelapse things. I am on my mobile and therefore don’t have the link at hand. Maybe you can find it with github forks view?

(Mica) #14 is alua plugin that isn’t ready yet, the other I saw was called timelapse_darktable and hasn’t been touched in 3 years.

(Tobias) #15

And there is this old issue:

The problem is still, that there is no method to manipulate iop parameters with Lua.
I think the deflickering option is now in dt:


Hey guys,

Who saw the abilities of LRTimelapse, knows, what DT, even with the de-flickering in the exposure, cannot do.

I would love to use LRTimelapse in the method it is meant (handshake with LR). I didn’t test yet, but afraid that the interpretation of DT when fed with LR-xmp-files will not always produce the results wanted.

Currently we cannot set several keyframes and edit those with interpolation between them. We can merely edit one and past it to all, which makes the fading light become constant…

timelapse-darktable seemed to do exactly that but even cannot install any more and way too outdated I am afraid.

Pitty Harry Durgin became quite inactive (understandably) behind his gallery. He would be the guy to figure it by tools :->> which I am not capable…

Anyone see a solution?!?

I had this problem a while ago when doing an eclipse timelapse and came up with a dirty script to do the work: (1.9 KB)
What I was trying to do was to simulate the light decay during the eclipse, so it’s kind of the opposite of what you what to accomplish. But maybe you can get some ideas from it. What the script does is:

  • look at the exposure of the picture (taken in auto exposure)
  • calculate the correction to apply in order to compensate for the camera’s exposure change
  • modify the parameter of the exposure module directly into a base.xmp file (not so simple, the numbers are encoded in a complex way, see encode_exposure file)
  • rename the base.xmp file and repeat for every picture

In this case I was also modifying the low-light module’s blending percentage, but the idea for that parameter is the same.
The script runs directly in bash (at least in Ubuntu’s flavor of it). Looking at it now it looks mostly gibberish (it was very clear back then!), but if you find it useful and need some help understanding it, just tell me.
