How to make videos

Animate your images, turn a description into a clip, or extend a video, plus how to write motion prompts that work.

Written by the fuckd.ai team ·

Videos start from a picture. You either animate an image you've already made, or describe a scene and let it be drawn and then animated. This guide covers the three video modes, the models, and how to write motion prompts that work.

The three video modes

  • Animate Image: brings one of your images to life. Pick the image, describe what happens, and generate. This gives you the most control, because you've already chosen the exact starting frame.

  • Text to Video: describe a scene and it's drawn as an image first, then animated into a clip. Quicker, but you don't get to approve the starting frame.

  • Extend Video: continues a clip you've already made by another 5 or 8 seconds, carrying on from its last frame.

Tip: for the best results, make the image first with Create Image, then animate the one you like. You can also press Make Video on any image in your gallery or chat.

Step by step

  1. Open Generate Media and choose Animate Image.

  2. Select the image you want to animate.

  3. Describe the motion, or pick a video preset.

  4. Choose a model, clip length and resolution in Settings. The cost updates as you change them.

  5. Press Generate.

Clips take anywhere from about 30 seconds to 5 minutes. Short, lower-resolution clips are quickest; long Ultra clips at the highest settings take the longest. You don't have to wait on the page: we'll notify you when it's ready, and it lands in My AI under Media.

Choosing a model

  • Standard: fast clips with sound, up to 15 seconds at 720p. The cheapest way to animate, at 4 Spunk per second.

  • Ultra: our best motion and detail, for the most demanding scenes. Up to 30 seconds at 480p, 720p or 1080p, with sound. It costs 16, 32 or 64 Spunk per second depending on resolution.

  • Extend: used by Extend Video. It adds 5 or 8 seconds to a clip, without sound, for 6 Spunk per second at 480p or 12 at 720p.

A 5-second Standard clip costs 20 Spunk. See What costs Spunk? for the full list.

Writing motion prompts

The starting image already shows who's in the shot, what they're wearing and where they are. Your prompt only needs to say what happens and how it moves.

What to include

  1. The main action, with a clear verb: she turns to the camera, leans in, rolls onto her back.

  2. How the body moves: hips, hands, hair, breathing, expression.

  3. Pace: slow, steady, building, fast. Say how it changes across the clip.

  4. Sound, on models that make audio. Describe what we should hear, such as breathing, laughter or the rain outside. Put anything they say in quotes: she whispers "come here". If you describe no sound, the clip often comes out silent.

What to leave out

  • Their appearance. Hair, clothes and body come from the image. Describing them again can make the clip drift.

  • Anything that isn't in the picture. New props, furniture or people won't appear convincingly. Keep the motion to what the scene already has.

  • Impossible moves. The motion has to start from the pose in the image. Someone lying down can't be dancing a second later.

  • Camera cuts, unless you want them. Clips are one continuous shot unless your prompt asks for cuts.

  • "No…" phrases. Say what happens, not what doesn't.

Example

  • You type: she dances

  • Better: She sways her hips slowly to the side, runs one hand up through her hair and turns to look over her shoulder at the camera with a teasing smile. The movement builds from slow to playful across the clip. Quiet room tone, and her soft laugh at the end.

Keep the prompt enhancer on

Like images, videos have a prompt enhancer that turns a short request into a fuller motion description, including sound for models that make audio. It's on by default. Turn it off when you've written the whole prompt yourself and want it used word for word.

Extending a clip

  1. Open the clip in your gallery and press Extend Video, or choose Extend Video in Generate Media.

  2. Describe what happens next in the clip.

  3. Choose 5 or 8 seconds and generate.

Extend Video is a membership feature.

If something goes wrong

If a clip fails or is blocked by moderation, the Spunk goes back to your balance automatically. See Why did my generation fail?
