Frequently Asked Questions

What types of watermarks can I add to my videos?

You can add both text-based watermarks (custom text with full font, color, and background control) and image-based watermarks (logos, signatures, or graphics). Both types support transparency adjustment, scaling, and precise positioning throughout your video.

How does the visual positioning tool work?

Our visual positioning tool captures a frame from your video and allows you to drag and resize a positioning box exactly where you want your watermark. This gives you pixel-perfect control over placement and scaling with immediate visual feedback before processing.

Can I control when the watermark appears in my video?

Yes, you can specify exact start and end times for watermark application. This allows you to add watermarks only to specific segments of your video or have them appear throughout the entire duration. Perfect for intro/outro sections or segment-specific branding.

What video formats are supported for watermarking?

We support MP4, WebM, and MOV input formats, and you can output to these same formats. The tool automatically handles format conversions when necessary while maintaining optimal quality. All major video codecs are supported.

Is there a limitation on video file size or duration?

You can process videos up to 2GB in size. There's no strict limit on duration, though longer videos will naturally take more time to process depending on your device's capabilities and the complexity of watermarking operations.

How does PixDuplicate ensure my videos remain private?

Complete privacy protection! All video processing occurs locally within your browser using WebAssembly technology. Your videos never transmit to external servers or cloud services, guaranteeing absolute confidentiality for sensitive or proprietary content.

Can I preview the watermark before processing the entire video?

Yes, our real-time preview feature shows exactly how your watermark will appear over your video. You can scrub through the timeline, adjust settings in real-time, and see immediate visual feedback before committing to the full processing stage.

Can I save watermark settings for future videos?

Yes, you can save your watermark configurations as presets. This includes text content, positioning, timing, opacity, and all other settings. Perfect for maintaining consistent branding across multiple videos or batch processing projects.

What image formats are supported for logo watermarks?

We support PNG, JPG, JPEG, SVG, and WebP formats for watermark images. PNG format is recommended for logos with transparency, as it will blend seamlessly with your video content without a visible background.

Does the watermarking process reduce video quality?

You have complete control over output quality. We offer quality presets from high to low, allowing you to balance file size and visual fidelity. With high-quality settings, the watermarking process maintains excellent video quality with minimal perceptible difference from the original.
