The KimaraAIWatermarker custom node allows you to apply watermark text and logo overlays to images. Optionally, the watermark can be moved by the move_watermark_step amount of pixels after each generated image. To apply a moving watermark to a list of images, use the KimaraAIBatchImages node to concatenate the list into a single tensor, then use that as an input for the watermark node, as shown in the example image below.

The KimaraAIWatermarker custom node allows you to apply watermark text and logo overlays to images and videos. Optionally, the watermark can be moved by the move_watermark_step amount of pixels after each generated image.

Features

  • Add watermark text to images and videos.
  • Add logo watermarks to images and videos.
  • Move watermark across images in customizable steps.
  • Adjust opacity of watermark image and text.
  • Adjust size of the watermark image and font.
  • Use custom fonts by setting the font path.*
  • Rotate watermark image.**
  • Batch processing for multiple images.

* When running ComfyUI in a container, the font path in /assets/fonts must be the full path from the workdir, e.g., custom_nodes/ComfyUI-Kimara-AI-Advanced-Watermarks/assets/fonts/DMSans-VariableFont_opsz,wght.ttf.

** Rotation currently only affects the watermark image.
