## B-roll without speech

Previously the reel was built mostly from speech. Now the director understands what happens in shots without words and places such B-roll in the reel by meaning. Every uploaded video is used — nothing is lost, even if it has no speech.

## AI effects from a prompt

-   Describe an effect in words — “make it snow” — and a neural network changes the video in the chosen range.
-   The range is 2 to 30 seconds, or the whole reel if it is shorter.
-   The price is ≈2.2 tokens per second of the range, shown on the button before you start.
