A storyboard is only useful if it turns into the film. In cnemai every frame of the board is a shot with its own page: the first frame, the stills you tried, and the video takes, side by side.
A first frame for every shot
Each shot opens on its first frame. Try a few stills to find the look, cheaply, before you spend on video.

Takes, priced before they render
Ask for a take in plain words, from the still or from references. The price shows first. Try another model if the first one misses, and keep every take on the shot.

Onto a real timeline
Lay the takes on the Main lane, add voice, sound, score and captions, and save versions as you go. Export a 1080p master.
