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.

Can I mirror a video horizontally?

Yes. Choose horizontal flip for mirror-style correction or vertical flip for upside-down footage.

Can I flip both directions?

Yes. Applying both directions creates a 180-degree mirrored result.

Can I mirror a selfie video?

Yes. Use horizontal flip to mirror the frame and export a corrected MP4.

Is flipping different from rotating?

Yes. Flipping mirrors the image, while rotating turns the frame by an angle.
