Why use Aback Video for this

  • Seamless join

    The two remaining parts are re-encoded together, so there is no jump, stutter or missing audio at the join.

  • Exact boundaries

    Because the video is re-encoded, the removed section starts and ends on the frames you choose, not on the nearest keyframe.

  • Sound stays in sync

    Audio is cut at exactly the same points as the picture, so voices keep matching lips after the cut.

  • No upload

    Everything happens in your browser tab. The file is never sent to a server.

Frequently asked questions

How is this different from Trim Video?

Trim keeps one continuous part and throws away the start and end. Remove a Section does the opposite: it deletes one part from the middle and keeps everything around it.

Can I remove several sections?

One section per run. For a second cut, run the tool again on the result. Each pass re-encodes, so for many cuts it is quicker to split the video and merge only the parts you want.

Why does it take longer than trimming?

Joining two pieces cleanly needs a re-encode, and the encoder runs on one CPU thread inside the browser. Expect roughly real time for 1080p on a recent laptop, slower on phones.

What does the output look like?

An MP4 with H.264 video and AAC audio, at the original resolution and frame rate, at a high quality setting.

Is the video uploaded anywhere?

No. FFmpeg runs inside your browser and reads the file from your disk. Nothing leaves your device.

Does it work on phones?

Yes, in current Safari and Chrome. Long clips need more memory to re-encode, so on a phone trim the video first if it is very long.
