Claron
A meteor crossing a star field above a dark mountain ridge, the last of the sunset still on the horizon

The night,
without the noise.

Claron stacks a night timelapse, frame by frame, and hands the sequence back to LRTimelapse with every shooting time still on it.

One frame is mostly noise.

Thirty seconds at ISO 6400 is a compromise, and it looks like one. Stacking the frames averages the noise away. But a fixed tripod moves the sky and holds the ground, and the two cannot be stacked the same way.

Separate the sky from the ground.

Claron stacks each on its own terms. The sky is aligned to the stars with rejection loosened so they survive being stars; the ground is left as shot with rejection tightened. Measured on a real twenty-frame sequence:

Mountain peaks above a sea of cloud at dusk, sky and land clearly divided
52px
of foreground smearing avoided across twenty frames
33.2×
star signal over the sky background, up from 13.5×

Flicker goes. The sunset stays.

Matching every frame to the first one removes the flicker and the reason you went out with it. Claron separates the fast flutter from the slow curve and takes only the flutter, so a cloud crossing the moon for four minutes stays weather rather than becoming a defect.

It lands where you already work.

Out comes a Linear DNG sequence carrying each frame's original capture time, so LRTimelapse keyframes it like any other sequence. Already graded? Feed it the TIFFs and get TIFFs back, with no detour through After Effects.
