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 chroma key removal work?

The page compares each frame against the selected key color, turns matching pixels transparent, and composites the remaining subject over a solid or image background.

Can I use blue screen or another color?

Yes. Choose any key color, then tune similarity and edge softness for the screen color in your footage.

Does this work like AI background removal?

No. This is best for real green-screen or blue-screen footage with an even background color, not complex natural scenes.

Can I replace the background with an image?

Yes. Choose an image background or use a solid color, then export a new MP4 locally.
