## Overview Video Watermark is a Wiro-native video utility that burns a watermark into every frame of an input clip. You can use either a logo image or plain text. The tool then composites the watermark onto the video at a fixed screen position and re-encodes the result. This solves a common delivery problem: you can ship videos with consistent ownership, attribution, or brand marks that stay visible after re-uploads. ## What you can build - Add a corner logo to product demos and app walkthroughs - Stamp creator handles onto short-form clips for reposting - Add copyright or attribution text to training clips and internal demos - Apply consistent branding across a batch pipeline of exported videos - Place a readable text watermark with a background box over busy footage ## Inputs - One input video file to watermark. - One watermark source: - A watermark image you upload. Transparent images keep their transparency. - Or a watermark text string. - If you provide both, the image watermark takes priority and the text gets ignored. - A fixed placement preset for the watermark. You can choose from 9 positions: top-left, top-center, top-right, center-left, center, center-right, bottom-left, bottom-center, bottom-right. - Watermark opacity as a percentage from 0 to 100. - Edge margin in pixels from 0 to 1000. This sets the distance from the frame edge for non-centered placements. - For image watermarks: a scale percentage from 1 to 100 that sets the watermark width relative to the video width. - For text watermarks: - An optional font size in pixels from 8 to 400. If you leave it empty, the tool scales it from the video height. - A font color as a CSS-style color name (example: white) or a hex color value (example: #FFFFFF). - An optional on/off toggle that draws a translucent dark box behind the text. ## Outputs The model returns a single video file that matches the input timing, with the watermark burned into the frames. The watermark stays fixed to the chosen screen position for the full clip. ## Limitations - This tool burns the watermark into the video. It is not an invisible watermark. - Center placement ignores margin because there is no edge offset. - Image scaling is proportional to video width. Very small logos may become unreadable at low scale. - Text readability depends on footage contrast. Busy backgrounds may require the text background box. - Low-quality inputs can cause issues. Heavy compression, noise, or low resolution can make the watermark look blurry or jagged. ## Safety & compliance - Only watermark videos you have the rights to modify and redistribute. - Don’t add misleading ownership marks to third-party content. - If the video includes people, make sure you have consent for the intended use. - Respect trademarks and brand guidelines when adding logos or brand names.
