You’ll now see that your video has changed dimensions within the video canvas in the middle of the Vidds editor.

You now have the possibility of editing your video further, add text, image overlays, animations, music, voiceovers and much more.

When you are happy with the new size of your video, simply click “Save” and then the “Download” button to begin rendering your new video with watermark added.
