How it works
- Drop one or more MP4 or MOV videos onto the box.
- Type a line of text, choose a logo picture, or both.
- Choose the corner, the size and the opacity.
- Press Add watermark and download the new MP4s. The sound is kept. That holds for AAC sound, which phones record; another kind (PCM in a camera MOV) is left out, and the result says so.
