The Waymark video editor and video preview playback an approximation of what your final video file will look like. This can mean that some images may appear to have slightly sharper un-smooth edges. That's due to the technology used to make your video editable right from your browser.
Sharper un-smooth edges in images usually do not appear in your final downloaded video.
Tip: Playback your video preview in full-screen to see if sharp edges still occur, be sure that your images meet our recommended image size guide and if issues persist after you download your video, reach out to our support team for further assistance.
