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.

Why can processing take time?

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

Which browsers work best?

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

What should I try if a large file fails?

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

How does automatic background blur work?

The page uses MediaPipe person segmentation to make a person mask, blurs the full frame, then composites the sharp person back into the exported MP4.

Does the video upload anywhere?

No. The selected video, segmentation, rendering, and MP4 export run locally in your browser.

Can I blur only the background?

Yes. The tool is designed to separate the subject from the background and apply blur around the subject.

When can background blur look imperfect?

Fast movement, low light, cluttered scenes, or unusual subject edges can make segmentation less precise.
