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.

The work runs in your browser, so speed depends on your device, browser, memory, source size, and the export settings needed for the result.

Recent Chrome, Edge, and other modern Chromium browsers usually work best for heavier browser media processing.

Try a smaller source, close other heavy tabs, reduce resolution or duration first, and keep the tab open until the export finishes.

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

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

Core details about privacy, browser support, output, and practical limits before you start.

The selected video is transformed locally in this browser with the Mediabunny/WebCodecs pipeline.

Rotate 90 degrees clockwise, 90 degrees counterclockwise, or 180 degrees.

Flip the frame horizontally or vertically before exporting the final MP4.

Check supported inputs, output formats and usage requirements before you start.

Supported input	Video files such as MP4, MOV and WebM. Container and codec support depends on the browser and processing runtime.
Output result	Export options: MP4.
Processing and privacy	Processing runs on this device. Source media is not uploaded for this workflow.
Browser requirements	A browser with the decoding and encoding capabilities needed by the selected media. Available codecs vary by device.
Usage limits	Processing capacity depends on duration, dimensions, codecs, settings and available device memory. Large inputs can fail; keep the original file.
Does this change the actual video file?	Yes. The exported MP4 has the rotation or flip burned into the pixels, not just metadata.
