123 Bulk Video Watermark is a Windows desktop application that allows you to add image and text watermarks to multiple videos at the same time. It is designed for users who need an easy and reliable way to protect video content, apply branding, or prevent unauthorized reuse without editing each video manually.

Start by clicking the Browse button in the Watermark Image section and choose the image you want to use as a logo. Once loaded, the program displays the original image size in pixels and automatically updates the scaled size when you change the percentage value. You can adjust the watermark scale, opacity, margin, and position (corners or center) to fit your video layout. The program also supports text watermarks, giving you full control over font, size, color, opacity, and placement. For stronger protection, text watermarks can be centered and rotated at a 45-degree angle, making them clearly visible while remaining non-intrusive.

The batch processing system allows you to add multiple videos to a queue and process them all at once. You can choose the output format, define a custom output folder, and process several videos in parallel for faster results, while keeping the original audio quality intact.
