Video Clipper

Many clips from one video, in one pass

Long recordings — a stream, a talk, a podcast video, a day of phone footage — usually hold several moments worth sharing. The clipper keeps all of them on one timeline. Drag across an empty track to cut a clip; drag it to move it, and drag either edge to extend or trim it. Clips can overlap: a short close-up can sit inside a longer scene, and each overlapping clip gets its own track so nothing hides behind another. New and moved clips snap to the playhead, and every edge snaps to the ends of the video and to the edges of other clips, so back-to-back clips line up exactly.

Frame each clip for where it is going

A clip for Reels, Shorts or TikTok wants 9:16; a feed post wants 1:1 or 4:5; a YouTube cut stays 16:9. Select a clip and drag on the video to draw its frame, or choose an aspect ratio and the frame snaps to it, keeping the same centre. Move the frame by dragging inside it and resize it from the corners. Preview output zooms the player to exactly what the exported clip will show. Each clip keeps its own frame, so one source can produce a vertical highlight and a square teaser side by side.

Precise in and out points

Every clip has an in and an out point you can nudge one frame at a time, or set straight to the playhead. Split at playhead turns one clip into two at the current frame; Merge with next joins a clip with the one after it, keeping both sets of tags and notes. Play clip loops just that section so you can check where it starts and ends. Clips can be named, tagged and annotated, and the names become the exported file names.

Your video never leaves your browser

The clipper reads and encodes the file on your own device with the browser's WebCodecs video engine. Nothing is sent to the PixelTools servers, so there is no upload wait, no file-size limit imposed by a server and nothing stored afterwards. Your clips — their times, frames, names, tags and notes — are remembered in this browser for the 20 most recent files, so you can close the tab, reopen the same file and pick up where you left off; the video itself is never saved.

What the exported files contain

Each clip is cut at its exact in and out points and re-encoded, rather than snapped to the nearest keyframe, so it starts on the frame you chose. The video is cropped to the clip's frame in source pixels, rounded to even dimensions as H.264 requires, and is never scaled up, and the source frame rate is kept. The result is an MP4 that uses H.264 video when your browser can encode it. Audio such as AAC is copied from the source without re-encoding, so it sounds exactly as it did; audio the MP4 cannot carry is re-encoded, and if your browser has no compatible encoder the clip is exported without sound and marked as such. Encoding speed depends on your device, the length of the clip and its resolution.
