Wide, vertical or square, chosen when you create it. Vertical frames are fitted rather than cropped.
Publishing is a deliberate act: you create the link, and until you do the video is yours alone.
Coming back to an unfinished job restores the text you wrote and the settings you chose.
Whiteboard draws in black on white the way its name always promised, the colour it used to have became a style of its own, and every style can now be looked at before you spend a video finding out.
The frames became a step you can look at before the video is made, one picture can be fixed without remaking the rest, and a scene can run as long as you tell it to.
Any video can be downloaded in any shape without being cropped, the styles in the app match the ones on the site, and minutes come back when a render does not happen.
Everything that changed, newest first.
