Sprunkity Image to Video: Turn One Character Still into a 10-Second Clip

To make a Sprunkity-style video on sprunkity.org, start from one character image (JPG, PNG or WebP, up to 10 MB) or a written prompt, describe the motion in a sentence or two, and render a 10-second, 720p, 9:16 silent MP4 for 30 credits. sprunkity.org is an independent, fan-made AI video tool inspired by the Sprunki scene; it is not the game and is not affiliated with sprunki1000, itch.io, Incredibox or TheGoodSprunkiOwner124.

The short version

• One input per render: a written prompt or a single character image.
• Output is fixed at 10 seconds, 720p, vertical 9:16, silent MP4.
• Every render costs 30 credits; new accounts start at 0 credits.
• Paid renders carry no watermark, and failed generations return their credits automatically.
• The model generates new motion. It does not rig a 3D character, so likeness is approximate, not exact.

What image-to-video actually does

Image-to-video takes a still picture and produces a short clip that looks like the picture moving. It is not animation in the traditional sense, and it is not rigging. There is no skeleton, no joint hierarchy, no keyframes and no control over individual limbs. The model reads the image, reads your prompt, and generates new frames that are statistically plausible continuations of what it sees.

That has practical consequences you should plan around.

First, identity is approximate. The clip usually resembles your input, but fine details such as a small accessory, an exact pattern on a shirt or the precise shape of a hair tuft can drift over ten seconds. Second, you cannot direct body parts precisely. Asking for a specific hand gesture or a particular foot placement often produces something close but not literal. Third, the model fills gaps with invention. If your image is ambiguous about what is behind the character, the model will invent a background that moves with the scene.

The useful way to think about it: you are not animating a character, you are generating a new ten-second shot that starts from your character. Write prompts and choose images accordingly.

What makes a good input image

The single biggest factor in output quality is the input. A clean, readable image gives the model less to guess about.

Full body. Show the character from head to toe, or at least from head to mid-thigh, with space around them. Cropped images force the model to invent the rest of the body, and invented bodies are where extra limbs and warped torsos come from.

Clear silhouette. The character should read as a distinct shape against the background. If the character is the same value and colour as what is behind them, the model struggles to separate foreground from background, and edges smear.

Simple background. A plain or softly blurred background is easier to work with than a busy scene. Detailed backgrounds tend to melt and warp because the model has more to invent and less to anchor to.

Even lighting. Flat, consistent light across the character keeps colours stable. Hard shadows and strong rim light create ambiguity that shows up as flicker.

One character. Put one character in the frame. Multiple characters invite the model to merge them or assign motion to the wrong figure.

A quick pre-upload checklist:

1. Open the image at full size and check the character is complete in frame.
2. Confirm there is only one character.
3. Check the background is simple enough that you could describe it in a few words.
4. Look for harsh shadows or blown-out highlights and fix them if you can.
5. Confirm you own the image or have permission to use it.
6. Save as JPG, PNG or WebP under 10 MB.

Writing the motion prompt

The prompt describes what happens in the ten seconds. It does not need to describe the character in detail — the image already does that. Keep it short, concrete and physical.

Three things to cover: action, camera and mood.

Action is what the character does. One clear movement beats three overlapping ones. "Sways gently and nods" works better than "dances, spins, waves, jumps and points."

Camera is how the shot is framed over time. "Fixed camera" is the most stable choice. "Slow push in" and "slight handheld drift" also work. Fast camera moves tend to break the image apart.

Mood sets lighting and pace. "Warm afternoon light, relaxed" or "cool night lighting, tense" gives the model a consistent direction without asking for effects it cannot deliver.

Some example prompts:

• "The character bobs gently in place, arms loose at their sides, fixed camera, warm afternoon light, cheerful."
• "The character turns their head slowly toward the camera, slight smile, slow push in, soft even lighting."
• "The character sways side to side with a relaxed bounce, camera fixed, simple studio lighting, mellow mood."

Avoid stacking requests. Prompts that ask for a specific dance routine, a costume change, a background swap and a camera move in ten seconds usually produce a muddled result. If you want two different actions, render twice.

Common artifacts and fixes

Warped faces. Typically caused by a small face in a large frame, or by asking for expressive facial motion. Fix: upload an image where the face occupies more of the frame, and keep the facial direction simple, such as "slight smile" rather than "laughs and winks."

Extra limbs. Usually caused by cropped bodies, busy silhouettes or prompts describing complex arm movement. Fix: use a full-body image with clean separation from the background, and describe one simple arm or body action.

Background melting. Caused by detailed backgrounds and camera movement. Fix: simplify the background, and use a fixed camera.

Identity drift. The character slowly stops looking like the input. Fix: shorten the described action, avoid fast spins and large pose changes, and keep the framing tight enough that the model has strong reference.

None of these are failures in the billing sense. A render that completes but looks wrong is a completed render; only failed generations return their credits automatically. Budget for a couple of attempts when you are trying something new.

Rights, consent and privacy

Use images you own or have explicit permission to use. Fan art of Sprunkity characters is still someone's art, and rights in the game, its characters and its artwork belong to their respective creators. Being able to upload something is not the same as being allowed to publish it.

Do not upload a photo of a real person without their permission, and never use a real person's likeness to impersonate them or to make it look like they said or did something they did not. Do not create sexualised depictions of minor characters. Label AI-generated output as AI-generated when you post it.

Inputs and outputs are moderated. Treat anything you upload as something that will be checked.

Cost and download

Every render costs 30 credits, whether it starts from a prompt or an image. New accounts start with 0 credits, and there is no signup bonus or check-in reward.

Credits come in three shapes. Monthly plans run Starter 20 credits at $9.90, Basic 60 at $19.90, Pro 200 at $39.90 and Studio 500 at $79.90, and those credits expire at the end of each billing month. Yearly plans run Starter 240 credits at $79, Basic 720 at $159, Pro 2,400 at $319 and Studio 6,000 at $639, valid for the billing year. One-time packs run Single 10 credits at $9.90, Duo Pack 30 at $19.90, Party Pack 100 at $39.90, Crew Pack 250 at $79.90 and Studio Pack 600 at $149, and those credits never expire. Full details are on the pricing page.

Output is a 10-second, 720p, 9:16 silent MP4. Paid renders have no watermark. The file is silent by design, so you add music you have the rights to in your editor. Failed generations return their credits automatically.

FAQ

What image formats work? JPG, PNG and WebP, up to 10 MB per image. One image per render.

Can I use a photo of a real person? Only with that person's permission, and never to impersonate them or to make it appear they did something they did not do. Do not upload photos of people who have not agreed to it.

Will the character look exactly the same? No. The model animates a new clip rather than replaying your image, so details such as small accessories, patterns and exact facial features can shift. Simpler images, simpler motion and a fixed camera reduce drift.

Keep creating

If you want to go further, these guides pair well with this one: start with prompt wording in Sprunkity text-to-video prompts, get character details right with Sprunkity characters, and check what is acceptable to publish in Sprunkity fan video rules.

When you are ready, open the create page to upload an image or write a prompt, and check pricing to pick the credit pack that matches how many renders you actually plan to make.
