How can I align and crop a series of photos so they overlay perfectly for a time-lapse?

I’m photographing the same subject repeatedly over several days and want to turn the images into a simple time-lapse/slideshow. Even with a tripod, the framing shifts slightly between shots, so I need a fast way to align the images and then crop them consistently so they match each other.
Is there a good workflow or software for auto-aligning a stack of photos and exporting/cropping them so they overlay cleanly?

Panorama applications can usually auto-align a stack of photos since this is a special case of the adjustments needs for correct stitching.
For instance how you can use Hugin for this is shown here.
To get to the interface used in the guide, go to View -> Panorama editor. Also make sure Interface in the menu bar is set to Expert, or the Remapped Images section used in the last step will not be visible.

A practical way to do this is to use panorama-stitching software. Auto-alignment for panoramas solves essentially the same problem: matching overlapping images that are slightly shifted or rotated.
Hugin is one option mentioned by the community. Load the image stack, let it auto-align the photos, then use the panorama/remapping tools to output aligned versions. After alignment, crop all images to the common overlapping area so every frame matches.
In Hugin, you may need to switch the interface to Expert mode and open the Panorama Editor to access the relevant controls, including remapped image output.
So the basic workflow is:
- Import all photos into panorama software.
- Run automatic alignment.
- Export the aligned/remapped images.
- Apply one consistent crop to the shared image area.
- Assemble the results into your time-lapse.
This is generally much faster than manually overlaying and adjusting 30 images one by one in an editor.
