How to Make a Fast Video – Cantina Help Center

A fast video is a short clip built from what you set up when you designed your bot and selected its profile video. In a fast video, you can control the dialogue (what your bot is saying) but not the action or anything else. Your bot is usually at one location, and captions are generated automatically. For example, when a bot gives a room summary, that's a fast video. This article covers every way to reach a fast video.

When you need something more than that, that's an Imagine video. See Fast Videos vs Imagine Videos for the full comparison.

Where to find Fast Video

There are four ways to reach a fast video.

From a chat with your bot

Every bot message in chat can be turned into a fast video.

Chat with your bot and let it reply.
Tap one of the bot's messages to open the video view.
Tap the Video button to turn that message into a fast video.
Generate.

From a bot's profile

You can start a fast video from a bot's profile without a chat first.

Open the bot's profile.
Tap Create.
The creation surface opens on the Video tab by default. Tap Quick at the top to switch to fast video.
Type your prompt.
Tap Generate.

From the Imagine tab

The Imagine tab has three sub-tabs across the top. Fast videos live under Quick on iOS and Message on Android. The other two sub-tabs are Video (Imagine's longer builds) and Image (image generation).

Open the Imagine tab.
Tap Quick (iOS) or Message (Android).
Pick the bot you want (the featured bot appears at the top).
Type your prompt.
Tap Generate.

From an image

Animate a still image with a dialogue prompt.

Open a bot's profile and tap Media.
Pick the image you want to animate.
Type your prompt in the field at the bottom.
Tap Create.

What you can direct in a fast video

In a fast video, you can tell the bot what to say. You cannot tell the bot what to do. Actions, camera moves, specific settings, and wardrobe are all Imagine territory.

Things that work well in a fast video:

Direct dialogue: "Say hi to Marcus for me."
A quick line in character: "Tell me a bedtime story in three sentences."

Things that belong in an Imagine video:

Actions: "Walks across the room, opens the door."
Camera direction: "Slow push-in on her face."
Setting changes: "Beach at sunset, waves crashing."
Wardrobe changes: "Wearing a blue coat."
Videos with multiple characters.

Tips for a good fast video

Refresh your base videos if fast videos start feeling repetitive. The variety in a fast video comes from your bot's stock, not from the prompt.
Use Imagine when you need something more. When you need action, camera, or a specific setting, use an Imagine video.
