Videos are exported as MP4, MOV and WEBM files optimized for quality while maintaining compatibility.
Preview videos are rendered in lower resolutions in order to give quick feedback of your changes. The default and fastest preview resolution is 270p, though you can raise it to 360p or 540p at the expense of slower preview renders. In order to adjust preview quality go to Preferences in the sidebar (the wrench icon).
Subscribers can also produce and download high-definition videos in 720p HD, 1080p HD, 1440p and 4K UHD, depending on the template and subscription plan.
