Frequently Asked Questions

How do I merge multiple videos into one?

Drop all your video files onto the box at the top of this page and send the request “Merge these videos into one”. Your videos will be merged into a single file, in the order you added them. Prefer a timeline? Use the classic video merger on this page.

Will merging videos reduce their quality?

Merging re-encodes the clips into one file, so it is not a bit-for-bit copy. The AI assistant encodes in your browser with FFmpeg (H.264 for MP4, VP8 for WebM) in standard 8-bit color at a standard quality setting: phone and camera clips look close to the originals, while very high-bitrate or 10-bit HDR footage can lose some detail.

What video formats can I merge?

You can merge almost any video format including MP4, MOV, WebM, MKV, and AVI. After merging, you can export to MP4, MOV, WebM, or MKV.

Can I merge videos with different resolutions?

Yes! Our video merger can handle videos with different resolutions. The output will be based on your export settings.

Is there a limit on how many videos I can merge?

There's no strict limit on the number of videos. However, very large projects may require more processing time and memory depending on your device.

Can I trim videos before merging them?

Absolutely! Ask the assistant to trim a clip before merging, or use the classic timeline editor to trim, cut, and adjust each video clip before merging them together.

How long does it take to merge videos?

Merging typically takes a few seconds to a few minutes depending on the total video length and your device's performance.

Are my videos uploaded to a server?

No! All processing happens locally in your browser. Your video files never leave your device, ensuring complete privacy.
