- Multiple Random Images Mode: Select a folder containing multiple images, and the program will randomly choose a watermark for each video to improve anti-duplication effectiveness.
Set Watermark Position:
- Fixed Position: Supports 3x3 grid positioning, such as top-left, bottom-right, center, and more.
- Random Position: Supports regular random placement (random within the 3x3 grid), irregular random placement (any coordinates), and timeline-based random placement (position changes over time).
Adjust Effect Parameters: Use sliders to adjust the watermark display size (percentage) and opacity in real time, and preview the best visual effect.

FAQ

A: The tool is developed based on the FFmpeg engine and supports common video formats such as MP4, AVI, MOV, MKV, FLV, and more. As long as it is a common video file, it can usually be processed smoothly.

A: This is an advanced anti-reupload feature of this tool. The watermark does not stay in the same position throughout the video; instead, it can be set to randomly change position every few seconds (such as every 3-5 seconds). This not only effectively covers the video frame but also greatly increases the video's originality, helping prevent it from being identified by machines as duplicate content.

A: The tool uses the x264 encoder and the fast preset by default to maximize speed while maintaining image quality. Actual processing speed depends on your computer configuration (CPU performance) and video resolution. The tool automatically maintains quality close to the original video.

A: If your videos need to be published on platforms with strict duplicate-content checks, we recommend preparing multiple Logo images in different styles or colors and placing them in a folder. After enabling this mode, each video (or time segment) will randomly select a different Logo, making the generated video files have different characteristics.

A: The core processing of the software runs entirely locally and will not upload your video files to any server, fully protecting the security and privacy of your materials. It only performs a simple permission verification once at startup.
