How to find shaky, blurry and dark clips automatically
The first pass of any cull is throwing out the junk: the walking shots that bounce, the clip that missed focus, the shot with the lens cap on, the third take of the same thing. None of that needs taste, so it should not need your time either. This guide shows how to flag those clips automatically and what you still check by eye.

Where a step names Basecut, it is our product, so judge that part on your own footage. The idea of measuring first and judging second works with any tool.
Why this part can be automatic
Some questions about a clip have a number for an answer. How much does the picture move from frame to frame? How sharp are the edges? How much of the frame is crushed to black or clipped to white? Is this nearly the same picture as another clip? A computer can measure all of that faster than you can watch it, across a whole card dump.
Other questions are taste: whether the shaky shot is the only one of the first kiss, whether the dark clip is moody on purpose. So the useful split is simple. Let the software flag, and keep the decision.
What gets flagged
| Flag | What is measured | Watch out for |
|---|---|---|
| Shaky | How much the picture moves from frame to frame, second by second, and which stretches stay steady. | Handheld on purpose, and fast action shots. |
| Soft | Sharpness across sampled frames of the clip. | Shallow depth of field and deliberate soft focus. Not yet proven on real out-of-focus footage. |
| Dark or blown out | Overall brightness, and the share of overexposed pixels. | Night scenes and silhouettes that are dark on purpose. |
| Duplicate | Near-identical takes, matched on a small visual fingerprint of sampled frames. | Two similar shots of the same spot can be grouped as one. |
| Test pattern | Color bars and similar test patterns. | Nothing: these are never a usable shot. |
Step by step
1. Import the whole card dump
Point Basecut at the card or the folder. It reads the files where they are and never changes the originals, so nothing you do in the next steps can lose a clip.
2. Read the rough view while the AI works
Within seconds of import, the import card shows a rough view of the shoot: how many clips look usable, shaky, soft, dark or blown out, or like a repeat of another take. These are plain measurements of the picture, not AI guesses. Clips with a flag get a small marker on their card, so you can start checking them before the AI pass finishes.
3. Let the AI rate the rest
The AI pass rates every clip as a hero, keeper, maybe or skip and finds its best moments. The AI looks at what happens in each clip, so a shaky clip with nothing in it tends to rank low. Basecut also measures shake second by second, so it knows which stretches of a clip are steady, and Auto Edit cuts from those stretches.
4. Filter down to the clips to check
Use the verdict filters (Hero, Keepers, Maybe, Skip, Junk) and the warning badges on each card to go straight to the clips that need a decision. Open a clip's preview to check it.
5. Make the call, quickly
Press A to keep a clip, R to reject it, S to pick a different take of the same shot, and U to undo. Reject moves the clip to the junk bin. Nothing is deleted, and the original file stays where it was.
6. Send only what is left to your editor
Open the result in DaVinci Resolve, Premiere Pro or Final Cut Pro with clips sorted into bins or keyword collections by rating, so the shaky rejects never reach your timeline. Stabilize the keepers that still need it in your editor.
Where automatic flagging goes wrong
- It cannot tell shaky by accident from shaky on purpose. Check every flagged clip that might matter before you reject it.
- One great moment can hide in a shaky clip. Look at the steady stretches before you throw the whole clip out.
- Dark is not the same as bad. A candlelit dance floor will be flagged as dark.
- Two different shots of the same view can look like duplicates. Swap take lists every take of a shot with a preview, so you can check before you pick.

Questions people ask
Can software find shaky clips automatically?
Yes. Shake is a measurable thing: how much the picture moves from one frame to the next. Basecut measures it for every clip, second by second, in the first seconds of an import, and flags the clips that are shaky. It does the same for soft focus, dark or blown-out exposure, repeated takes and test patterns.
Does Basecut delete the shaky clips?
No. It flags them, and you decide. Even a rejected clip only moves to the junk bin inside Basecut; your original file is never touched.
What about shots that are handheld on purpose?
They will be flagged, because the measurement cannot know you meant it. That is why a flag is not a verdict. Basecut also sorts clips by how they were shot (drone, gimbal, tripod or handheld), and you can correct that if it files a clip wrong.
How well does it catch blurry, out-of-focus clips?
The soft flag measures sharpness across sampled frames of each clip. Our own test shoot had no truly out-of-focus clip, so we have not yet proven how well it catches real soft footage. Treat the soft flag as a hint and check those clips yourself.
Does Basecut stabilize shaky footage?
Basecut is built to find shaky clips, not to repair them for delivery. Its Auto Edit can apply light stabilization inside an auto edit, but for a shaky clip you need in the final film, use your editor's stabilizer.
Does the shake check upload my footage?
No. The measurements run on your computer. The AI pass that follows runs on your computer too when you use Argus, Basecut's own AI. Basecut Cloud and your own Gemini key send reduced-size sections to Google.
Let the junk find itself
Basecut flags shaky, soft, dark and repeated clips within seconds of import, then ranks the rest hero to skip. Mac and Windows. 14-day free trial, 5 free exports, no card.
