Every episode is researched, written, rendered and scored here. If TAC is worth something to you, a contribution goes straight back into making more of it — render time, music licensing, and the hours that go into getting the science right.
- Longer episodes, and more of them
- Original scores instead of stock
- More free tools for making your own films, like the Scene Board storyboard builder
Free download AI storyboard builder
Pictures are only the start. The storyboard builder gives you the workflow that turns them into a film — the same program used to plan every TAC episode.
TAC Scene Board
A storyboard program built for AI filmmaking. Every scene holds its shots, and every shot holds its stills, backgrounds, characters and creatures, so you can see the whole story before you generate a single clip.
Download free for Windows →Frame Grabber New
Save the exact last frame of a clip (or any frame) as a full-quality picture, then start your next AI shot from it. Runs in your browser: your video never leaves your computer.
