Cut Corners vs AutoFilmCrop

Two Lightroom Classic plugins solve the same problem: batch-cropping film scans so you don't hand-crop 38 frames after every scanning session. Here is where they overlap and where they differ.

Both plugins detect the exposed frame inside the film rebate, then apply crop and rotation as standard Lightroom develop settings — non-destructive, editable in the Crop tool, reversible from History. Both run batches from Plug-in Extras, both offer an interactive preview, both run entirely on your machine, and both give you 30 free crops to decide. If you scan film and crop by hand today, either one will save you real time.

The differences are in how much of the messy real world each one handles — film types, formats, difficult scans — and in how they are licensed.

AutoFilmCrop details are drawn from autofilmcrop.com's public pages as of July 2026; “not documented” means we found nothing published, not that the feature is absent. See their site for current features and pricing. AutoFilmCrop is an independent product — we're not affiliated, and by all accounts it's a good alternative plugin.

Where AutoFilmCrop is a better fit

AutoFilmCrop manages licenses through an activation server: a key activates on up to two computers, and you can deactivate a machine from inside the plugin to move it. If you want that kind of managed activation — or you already own it and it crops your scans cleanly — there is no reason to switch.

Cut Corners deliberately has no activation at all. Your key is validated offline, no account exists, and the plugin never touches the network. Which of those you consider the better licensing model is a matter of taste; we built the one we'd want to buy.

Where Cut Corners goes further

Built for the scans that don't cooperate

Real scanning sessions produce unevenly lit backlights, dark film-holder edges, sprocket holes, and thin underexposed negatives. Detection falls back through a threshold sweep and a backlight-flattening pass automatically, dark film carriers can be masked out, and every found edge is snapped to the sub-pixel rebate transition.

Honest about misses

A frame Cut Corners isn't sure about is never silently mis-cropped: it's left untouched, given a color label you can filter on, and the summary names the exact rule that rejected it and the measured value. You always know which frames to finish by hand and why.

Try both on the same roll

Both trials are free and need no account, so the honest advice is: run your trickiest roll through each and compare.

Frequently asked questions

Is Cut Corners an alternative to AutoFilmCrop?

Yes. Both are Lightroom Classic plugins that automatically detect the exposed frame in a film scan and apply a crop and rotation as normal, non-destructive develop settings. Cut Corners adds more film types, film-format presets, deeper detection tuning, and named skip reasons.

Can I try both before buying?

Yes. Both plugins offer a free trial of 30 crops with no account required, so you can run the same roll through each and compare the results directly.

Do either of them upload my scans?

No. Both plugins run detection entirely on your machine. Cut Corners additionally requires no license activation server — the plugin makes no network requests at all.

Which one works with Negative Lab Pro?

Both fit a crop-first workflow: crop and straighten the roll, then convert with Negative Lab Pro, Grain2Pixel, or FilmLab. Removing the film border and scanner background before conversion keeps them from skewing the color analysis.
