Does ArtPlayer add a watermark?

No. The trim workflow exports a clean MP4 without an ArtPlayer watermark.

Is the original video changed?

No. The original file stays on your device and the browser creates a new trimmed output.

Can I trim a video before compressing it?

Yes. Trimming first is a good way to reduce duration before using the video compressor.

Cut away unwanted starts, endings, or pauses while keeping the original file on your device.

Make a clean, accurate video cut

Trimming changes the kept time range rather than the original file. Preview both boundaries carefully so the result starts and ends where viewers expect.

Set useful start and end points

Leave enough context at the beginning for speech and motion to feel natural, and avoid cutting the final word, transition, or action at the end. When a precise boundary matters, preview a few seconds around each cut before starting the export.

Remove setup time, blank frames, and accidental recording tails.
Listen for clipped syllables when dialogue crosses a boundary.
Keep the selected range focused before compressing or sharing.

Protect the original recording

The browser creates a new MP4 and does not rewrite the source file. Keep that original until you confirm the output duration, audio synchronization, and playback. If the cut needs revision, start again from the source instead of trimming an already processed copy.

Preview the first and last seconds of the exported MP4.
Check that audio and video remain aligned.
Use Split Video when several separate clips are needed.
