Select a publish format and click Publish. HTML Canvas option is available only if your document is HTML5 Canvas type. In the Publish option, Animate selects default or last used publish/export options. To change the options, use the publish or export options.
For example, to change export settings of video format, click File > Export > Export Media/Video. Modify the settings and export, accordingly. Next time you use Quick Publish option for Video, Animate uses the modified settings. Similarly, to change options for HTML Canvas publishing, click File > Publish Settings.
