Split a video into several parts

Two ways to split: by number of parts or by length

“Equal parts” divides the video into 2, 3, 4, 5 or 10 pieces of roughly the same duration. It is the quickest option when you simply need a large recording in smaller chunks, for example a two-hour lecture in four parts of about thirty minutes each.

“Fixed length” starts a new part every 15 seconds, 30 seconds, 1 minute, 5 minutes or 10 minutes, and the last part holds whatever remains. This mode suits apps and platforms that limit clip length: you choose a length just under the limit and get a series of clips that can be posted one after the other. A single video can be split into up to 200 parts.

Lossless and fast, because nothing is re-encoded

Vidmini does not decode and compress your video again. Each part is made by copying the original video and audio data between two cut points into a new file. The quality of every part is exactly the quality of the source, and even a long 4K recording is split in seconds rather than minutes.

To make this possible, the cuts are placed on key frames, the complete images a video stores at regular intervals. On phone videos there is usually one every 1 to 5 seconds. A part can therefore be slightly longer or shorter than the length you picked, by up to that interval. What you do not get is overlap or missing footage: each part starts exactly where the previous one ended, so played back to back, the parts give you the whole video.

What you download

All the parts come in one ZIP file, so you do not have to save a dozen downloads one by one. Inside, the files are named after your video with a number: holiday-part01.mp4, holiday-part02.mp4 and so on, which keeps them in the right order in any file manager or upload dialog.

Each part keeps the container of the source: an MP4 gives MP4 parts, a MOV from an iPhone gives MOV parts, and the same goes for WebM and MKV. The parts open in the same players and editors as the original.

When splitting a video helps

Sharing on apps that cap clip length is the most common reason: a long story or status is posted as a sequence of shorter clips. Splitting also makes long recordings easier to handle, such as a lecture, a meeting, a webinar or a gameplay session that you want to review or publish in episodes.

It can also help when a file is too big to send in one go. Smaller parts are easier to attach to separate emails or to upload over an unstable connection. If each part is still too large, “Continue with this file” can take a result straight to another tool, for example the compressor.

Split, trim or merge?

Splitting cuts the whole video into consecutive pieces and keeps every second. If you only need one precise segment, such as a single scene or a highlight, use Trim Video instead: you set the start and end yourself, and it offers a frame-accurate mode. To put parts back together, or to join several clips into one, use Merge Videos.
