Split Video

Drop a video above and choose one of three ways to split it. The list underneath shows every piece with its start, end and length before anything is processed, so you can adjust the numbers until it looks right.

• Every … seconds — fixed-length pieces, for platforms with a per-clip limit. A five-minute video split every 60 seconds gives five one-minute clips.
• Into … equal parts — the same length each, whatever the total. Useful for sharing a long recording in manageable chunks or dividing a lecture into sections.
• At specific times — cut wherever you like. Type times such as 1:05, 2:40, 4:12.5; play the preview to find the moments.

Splitting for social platforms

Story and status formats cap how long a single clip can be, so a longer video has to be posted in pieces. Splitting into pieces of exactly the limit keeps each one as full as possible, and the files are numbered in order —clip_part01.mp4, clip_part02.mp4 — so they are posted in sequence. Limits change from time to time; check the current one in the app you are posting to and type it in.

Why the cuts are exact

Compressed video is built around keyframes — complete pictures stored every second or few — with the frames between them stored as changes. A quick "lossless" splitter can only cut at keyframes, so a piece meant to start at 1:00 might really start at 0:58 and repeat the end of the previous piece. This tool re-encodes each piece from exactly its cut point instead, so consecutive pieces meet on the right frame with nothing duplicated and nothing missing. Re-encoding uses your device's hardware encoder at a high quality setting, and the sound is kept in every piece.

Splitting, cutting and merging

Splitting keeps every part of the video and divides it up. If you only want one section and to throw the rest away,Cut & Merge trims a single range more directly — and can join pieces back together, so you can split a video, edit one piece (for examplechanging its speed), and reassemble it. If the pieces need to fit under an upload limit as well, run them through theVideo Compressor.
