Can I doodle on a video?
Yes, you can doodle on a video just like you would on any image or document. After you click the Comment button and select your commenting method, click the play button on the video to begin playing the video. You can pause the video at any point in your comment and use the Doodler to annotate. You can also doodle on the video as it's playing. When the comment plays back, the video will pause in any place you paused it, and your doodles will appear where you made them. See a tutorial on video commenting for more information.
Please note that doodling is not available for comments made by telephone or audio-file upload.
