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 preview subtitles before exporting?

Yes. The page previews uploaded subtitles before you burn them into the MP4.

Are subtitles burned into the video?

The export creates an MP4 with visible subtitles, so they appear even in players that do not load subtitle files.

Can I burn SRT subtitles into a video?

Yes. Upload a subtitle file, preview the timing, and export a video with subtitles burned in.

Should I use this or the Subtitle Editor?

Use Add Subtitles for burning subtitles into video. Use Subtitle Editor when you need deeper subtitle editing and translation.
