Common reasons to trim a video

A focused clip is easier to share, upload, and reuse. These are the most common trimming tasks.

Create a short social clip

Remove intros, pauses, and dead air before posting a focused clip to social media.

Prepare a lesson or demo

Keep only the explanation or screen recording your students or customers need.

Share a meeting highlight

Cut a long recording down to a decision, presentation segment, or useful quote.

Send a smaller message

Trim the unnecessary beginning and ending so the video is quicker to upload and watch.

Your videos stay on your device

The selected files are read in your browser and processed in local Web Workers with MediaBunny. They are not uploaded to MediaKit servers. Close the tab or remove the files when you are done to release local memory.

FAQ

Frequently asked questions

Are my videos uploaded?

No. Trimming runs locally in your browser with MediaBunny and Web Workers. Your selected files are not sent to a MediaKit server.

Which video formats can I trim?

You can add MP4, M4V, MOV, WebM, MKV, AVI, WMV, FLV, 3GP, MTS, M2TS, TS, OGV, DIVX, and XVID files when your browser can decode the contained tracks. Outputs include MP4, WebM, MKV, and MOV.

How accurate is the trim?

Precise mode re-encodes the selection for a frame-accurate result. Fast mode prioritizes speed and may use a compatible fast path or adjust to stream boundaries.

What is the difference between Fast and Precise mode?

Fast mode is the quickest option for compatible inputs. Precise mode takes longer because it re-encodes the video and lets you choose an output format and quality.

How large can a video be?

Each input video can be up to 2 GB. Large files need enough free memory and may take longer on phones or older computers.

Can I trim a video on my phone?

Yes, use a current mobile browser and keep the page open while processing. If the device becomes warm or runs low on memory, use shorter clips or Fast mode.
