Frequently asked questions

Find quick answers about privacy, browser support, exports, and what to try when a file is heavy.

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 change the clip order?

Yes. Add multiple source videos and arrange them before starting the merge.

Do source videos need matching formats?

The tool exports a new MP4, which helps normalize common source differences during the merge.

Can I merge clips from different sources?

Yes, but matching resolution, frame rate, and orientation usually gives a cleaner result. The export is normalized into one MP4.

Can I rearrange clips before merging?

Yes. Add the clips, place them in the order you want, then start the merge export.
