Batch Add Image Watermark to Videos

Go to Menu -> Tools -> Add Watermark to Video, as shown below:

1. Select the video files to add watermarks to. You can choose one or multiple files.
2. Choose the watermark image.
3. Select the watermark position: top-left, top-right, bottom-right, bottom-left, or center of the video.
4. Set the margin distances from the top and bottom edges, and from the left and right edges. The default is 10 pixels.
5. Set the watermark size. It is recommended to pre-adjust the image dimensions and set this to the actual image size to avoid distortion. The default is 50x50, meaning a width of 50px and a height of 50px.
6. Click "Start Execution" and wait for completion. Open the result save directory to view the output files.
