Cutting Video into Clips in the Browser
What this tool does
A video splitter takes one file and produces one or more shorter clips from it, without re-recording or opening a desktop editor. There are two ways to cut. Time range keeps a single stretch between a start and an end time and discards the rest. Split points lets you add the times where the video should be cut, so a video with three split points becomes four parts of whatever lengths you choose. It accepts MP4, M4V, WebM, and MOV files up to 500MB, and every clip keeps the format of the original file.
When to use it
Reach for Time range when you only want one moment: a highlight from a long stream, a single answer from a recorded interview, or the intro cut off a screen recording. Split points fits anything with an uneven structure — a match with several plays, a set with multiple songs, or a lecture you want to break into chapters. Add a point at each boundary and download the parts together as a ZIP. Because the cutting happens on your own device, large personal recordings never have to be uploaded first.
Example: two ways to cut a recording
Say you have a 40-minute MOV of a game session and want one great play. Choose Time range, play the video to the start of the play and press Use current position as start, play on to its end and press Use current position as end, then press Split Video. If instead you want the whole recording broken into chapters, switch to Split points, play to each chapter boundary, and press Add current position. The tool shows how many parts the points will make before you cut, and each part is listed with its start, end, length, and size.
Notes and edge cases
The clips are copied out of the original rather than re-encoded, so cutting is fast and nothing is lost in quality. The trade-off is that a cut can only land on a keyframe, a complete image the video is built around, which usually comes every few seconds. A time range therefore starts at the closest keyframe before your start time, so it can begin a little earlier than you asked, while it ends where you set the end. A split point cuts at the first keyframe after it, so the part before it runs a little past the point and the part after it starts there. Nothing is thrown away and the parts do not overlap. If a video has too few keyframes for every split point, you get fewer parts than points plus one, and the tool tells you.
Very long or high-resolution files are the other limit: cutting uses your device's memory, so a file that runs out of memory needs a shorter source. The first time you split, the page downloads the video engine, about 31 MB, from this site; after that it stays loaded until you leave the page.
