Rotato renders anything from crisp ultra high definition 4K images and videos for Youtube and Vimeo, to lean and light 720p, perfect for email and the mobile web.
All snapshots from now on will be using the resolution you selected, in old, current and new projects.
The setting will be saved along with your current document. New documents will use the default resolution.
These screenshots have a predefined resolution, following Apple's rules for App Store screenshots, so there is no way to change their sizes.
Note that the default resolution for web animations is lower than than one for movies. This is because your web visitors will download the entire animation in one go, unlike videos that typically use partial buffering or streaming. On the flip side, users will experience no delay after the video has been loaded. A good target size for a web animation is around 5Mb. Try and keep it less than 10Mb.
