Killstamp

Stop scrubbing through hours of footage. KillStamp watches your video for you. Import a video, show KillStamp which on-screen element to look for — a kill indicator, an alert, a timer, a score bug — and it scans your footage every second, logging exactly when that element appears. Then turn those moments into clips and CSV/JSON logs with a tap. Whether you're reviewing gameplay, breaking down film, or hunting for specific moments in long recordings, KillStamp finds every occurrence — automatically, offline, with your video never leaving your device. HOW IT WORKS 1. IMPORT — Load an MP4, MOV, or M4V from Files or Photos (or drag and drop on Mac). 2. MARK THE ELEMENT — Tap the same on-screen element on 3 different frames. An optional AI hint (Apple Intelligence) can suggest the area for you. 3. LOG EVENTS — KillStamp scans the whole video once per second with pixel-accurate template matching and builds a timestamped event log in real time. TURN MOMENTS INTO CLIPS Automatically create a clip around every detected event — you choose how many seconds before and after, in MP4 or MOV. Events close together merge into one clip, so nothing is dropped. Preview, rename, share, and multi-select in the built-in clip library. Save to Photos on iPhone and iPad; reveal in Finder or save to any folder on Mac. READ THE DATA Export the full second-by-second log — every detection with its confidence score — as CSV or JSON, ready for spreadsheets, editing timelines, or your own tools.
