You can easily add a watermark to your video using Vimeo– upload your video, customize the watermark design, adjust placement, and generate a watermarked video seamlessly. We recommend 64 x 64 pixels as your minimum file size. In addition, a transparent background (.PNG file) will give the best result. Vimeo also supports MP4, M4V, MOV, FLV, AVI, or WMV video file types so you can reach viewers no matter your preferred format.
