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 rotate and flip together?

Yes. Choose a rotation and optional horizontal or vertical flip before exporting the MP4.

Does this change the actual video file?

Yes. The exported MP4 has the rotation or flip burned into the pixels, not just metadata.

Can I fix a sideways phone video?

Yes. Rotate the video 90, 180, or 270 degrees and export a corrected MP4.

Can I rotate and flip in one export?

Yes. Apply rotation plus horizontal or vertical flip before creating the final file.
