Are files uploaded for this tool?

This browser tool processes the selected media locally on this device. The file is not uploaded to ArtPlayer servers for this workflow.

Will the export have a watermark?

No. ArtPlayer browser tools do not add watermarks to exported files.

The work runs in your browser, so speed depends on your device, browser, memory, source size, and the export settings needed for the result.

Recent Chrome, Edge, and other modern Chromium browsers usually work best for heavier browser media processing.

Try a smaller source, close other heavy tabs, reduce resolution or duration first, and keep the tab open until the export finishes.

This first version combines exactly two videos in a side-by-side or top-and-bottom layout.

The export ends when the shorter video ends, so neither side freezes or turns black.

Yes. Mix both tracks with separate volume controls, keep either track, or export muted video.

No. Decoding, compositing, audio mixing, and MP4 export run locally in your browser.

Core details about privacy, browser support, output, and practical limits before you start.

Place two videos side by side or stack them from top to bottom.

Choose landscape, portrait, or square output and decide whether each video fills or fits its half.

Mediabunny, WebCodecs, Canvas, and Web Audio process both files without uploading them.

Check supported inputs, output formats and usage requirements before you start.

Supported input	Two browser-decodable video files: a background and overlay, or two panels.
Output result	Export options: MP4.
Processing and privacy	Processing runs on this device. Source media is not uploaded for this workflow.
Browser requirements	A browser with the decoding and encoding capabilities needed by the selected media. Available codecs vary by device.
Usage limits	Exactly two videos, up to 10 minutes each. Export ends with the shorter source; device memory may impose a lower limit.
What happens when the videos have different lengths?	The export ends when the shorter video ends, so neither side freezes or turns black.
