How to split a long video into multiple clips without losing quality

ClipScissor is a free video splitter that runs entirely in your browser. You load one long recording, cut it into separate clips, trim and name each one, and download them all together as a ZIP. The video is never uploaded and never re-encoded, so it is fast and the clips keep the original quality.

It exists for one job: the step before editing. If you film twenty takes in one thirty-minute recording, you don't want to drag the whole thing into CapCut or Premiere and hunt for the good parts. You want twenty clean, named files first.

Step by step

1. 01

   Load your video

   Drag an MP4 or MOV onto the page, or click Choose Video. It opens instantly, because the file is read on your device rather than uploaded. Multi-gigabyte files are fine.

2. 02

   Find the cut points

   Click or drag on the timeline to scrub, or press Space to play. The arrow keys step one frame; hold Shift to step one second. Zoom the timeline with + and −, or hold Ctrl (⌘ on a Mac) and scroll.

3. 03

   Split at each boundary

   Press S or click Split to divide the clip under the playhead in two. Repeat wherever one take ends and the next begins. Splitting is instant; nothing is processed until you export.

4. 04

   Trim and delete

   Drag the green handles at a clip's edges to trim its start and end; the footage you cut away shows hatched while you drag, then the clips close up. To leave a take out entirely, select it and press Delete. Handles snap to the playhead and to keyframes; hold Alt to drag freely. Every edit can be undone with Ctrl Z.

5. 05

   Name each clip

   Type a name in the sidebar or directly on the clip. The sidebar shows exactly the filename you will get: each file is prefixed with its number, so 02-product demo.mp4 always sorts after 01-intro.mp4, whatever the operating system.

6. 06

   Export as ZIP

   Click Export Clips. Each clip is generated on your device at original quality and the whole set downloads as one ZIP, ready to import into your editor. To grab just one clip, use the download icon on its sidebar row.

Why the clips are lossless, and what a keyframe means for your cut

Most video tools split a file by decoding it and encoding it again. That is slow, it depends on your computer's encoder, and every pass loses a little quality. ClipScissor instead copies the original compressed video and audio packets straight into a new file. The result is bit-for-bit the same footage: same resolution, same frame rate, same bitrate, same audio. It is also why a 20-minute recording exports in seconds.

Copying has one constraint. Compressed video is stored as occasional complete frames (keyframes) with the frames in between described only as changes from the previous one. A clip can therefore only begin on a keyframe. Phones and cameras usually place one every one to two seconds; screen recorders often less often.

When your cut falls between keyframes, ClipScissor starts the clip at the keyframe just before it, so you never lose footage you asked for. The clip includes a moment of lead-in that is easy to trim in your editor. If you want an exact start, drag the clip's start handle: it snaps to nearby keyframes. The end of a clip is always where you put it, give or take a frame.

Who it's for

TikTok, Reels and YouTube creators who film many short videos in one session. UGC and course creators recording take after take. Podcasters cutting a long recording into segments. Anyone who wants to break a long recording into clips before editing, and who would rather not upload a private file to a website to do it.

ClipScissor is deliberately not a video editor. There are no effects, captions, transitions or music. One video in, clean clips out, and then your editor does the rest.

Frequently asked questions

Is my video uploaded anywhere?

No. ClipScissor reads, splits and zips your video inside your browser. The file never leaves your device, which is also why there is no waiting for an upload. The page itself loads ads and anonymous usage analytics, but never your footage or filenames.

Does splitting reduce the quality?

No. The original video and audio data is copied into each new file without re-encoding, so resolution, frame rate, bitrate and audio are identical to the source.

Why does a clip sometimes start slightly before my cut?

Compressed video can only begin on a keyframe. Rather than re-encode your footage, ClipScissor starts the clip at the keyframe just before your cut. You keep everything you asked for plus a short lead-in. Snap the start handle to a keyframe for an exact start.

Which video formats are supported?

MP4 and MOV containing H.264 (AVC) or H.265 (HEVC) video with AAC audio: footage from iPhones, Android phones, most cameras and screen recorders. Clips keep the same container and codecs as the source. WebM and MKV are not supported yet.

Which editors can I use the clips in?

Any of them. The clips are ordinary MP4 or MOV files, so they import into CapCut, Premiere Pro, DaVinci Resolve, Final Cut Pro, iMovie and everything else exactly like footage straight off your camera.

How large a video can I split?

Multi-gigabyte recordings are fine; the video is read in small pieces instead of being loaded into memory. A ZIP created in the browser can hold up to 4 GB, so beyond that ClipScissor downloads your clips one by one instead.

Is it free? Is there a watermark?

It is free, with no account, no watermark and no limit on the number of clips. The ads on the page pay for it.

Which browsers work?

ClipScissor is built for desktop Chrome and Edge, which have the media APIs it relies on. Other modern browsers may work but are not yet fully tested. Phones can load, split and export a video, but a desktop is a much better place to edit.
