The pictures used to be the one thing you could not look at until the video already existed, which is backwards, because the pictures are the product. There is now a step between the storyboard and the video: the frames are drawn and shown to you, as a set, the way a viewer will see them. If you would rather not stop and look, the make-video button goes straight past it.
Do not like a frame? Redraw it, or write in your own words what should be there instead. That one frame is replaced and the rest of your video is untouched.
Write [seconds] 45 in a scene and it lasts 45 seconds. The drawing spreads across the whole time, so a single board can build itself slowly while you explain it. Before this, length followed the narration, and a three-word line meant a ten-second video however complicated the drawing was.
A caption and a drawing with no narration is a scene now, and it stays as long as you tell it to. It used to be thrown away.
Five scenes in, five scenes out. Your own drawing instruction is drawn as you wrote it rather than reinterpreted.
One button reads your script back the way we understood it, before anything is made: how many scenes you will get, which ones will be silent, and how long the video will run.
Every frame is now described in full before it is drawn, down to the exact list of words allowed to appear in it, and what comes back is checked against that list. A frame with a wrong or invented word is redrawn on its own. Your video is never redrawn.
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.
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.
A PDF, a Word file, a screenshot or a photo of a whiteboard can be the source of a video, instead of typing a topic.
