Has anybody tried some of the online storyboarding options, like Plot? Seems to make the formatting easier. https://theplot.io/
Also, give Plot (https://theplot.io/) a try. It can be a million times easier, depending on your workflow. :-)
In the first version, default aspect ratio will be 16x9. There may or may not be a limit at a 1920x1080 resolution. File type limitations are to be determined, but JPG and PNG support is a safe bet.
Thanks for the idea. Yeah, so essentially allowing file attachments to scenes, as a point of a reference for all sorts of things.
P.S. Built-in animatic editing is on our radar too!
Awesome. Yes, the current method will be dependent on uploading your own images (which can be anything you wish).
I know this is an old post, but thought I'd let you know we're finally working on a modern storyboarding app called Plot (http://theplot.io) that will eventually become exactly what you're looking for. Other feature requests are welcome! :-)
