Image to Video Stickman: Keeping the Character Consistent
Stickman Video DirectorWhy separately generated stickman shots drift, and how a first-frame image anchors the character across a multi-shot video.
The image to video stickman workflow exists because a text description is a weak handle on a character. Write "a stickman in a red beanie" into three consecutive shots and you can end up with three different stickmen. Uploading the same frame as the starting point of each shot gives the renderer something concrete to hold. This article covers why the drift happens, how the first-frame anchor works, and what to check before you render.
Why characters drift between shots
Every render begins as noise. The model starts from a field of random pixels and steers it toward an image that matches the text prompt. Nothing from the previous shot is carried forward: not the line weight, not the head shape, not where the elbows sit. Shot two has no idea shot one happened.
So the prompt is the entire memory, and prompts are read loosely. "Stickman" and "simple stick figure" are the same request in spirit and different requests in practice. Swap "round head" for "circular head" and the model may decide the character needs a wider torso or thinner limbs. These changes are small on their own; across six shots they add up to a character who looks like a cousin of the one in shot one.
Line weight is the quietest offender. A prompt that reads as "bold outline" in one shot and "clean line" in the next can shift stroke thickness noticeably, and stroke thickness is most of what makes a stickman read as the same stickman. Without a reference frame, the model measures against nothing and guesses each time.
The first-frame anchor
Image-to-video changes the starting condition. Instead of inventing a first frame from the prompt, the renderer uses the image you upload as the opening frame and animates forward from it. Proportions, line weight and silhouette are already decided. The prompt's job shrinks from "describe this character" to "describe what happens next."
That is the whole technique: use the same drawing for every shot in the sequence. Not a redrawn version, not a similar pose, the same file. If shot one shows the character standing and shot two needs them mid-stride, you can start from the same image and prompt the movement, or prepare a second anchor for that action. What you should not do is let each shot invent its own character in text.
A practical habit: build one anchor per character, plus one per pose you plan to return to. A four-shot video with one character might use two anchors, a neutral standing frame and a reaching frame. Two anchors are easier to track than six prompts, and the renderer treats both as authoritative. If the surrounding planning is new to you, the AI stickman video generator guide covers how a script becomes a shot list.
Preparing the anchor image
The anchor does most of the work, so get it right before you spend a credit.
Clean background. A uniform background makes the silhouette unambiguous. The renderer should not have to guess whether a dark patch behind the character is a shadow, a prop, or part of the arm. White or one flat color is enough. Skip gradients and clutter.
Full body, limbs separated from the torso. A stickman whose arms are fused to the body at the start of a shot tends to stay fused. Leave visible gaps between arms and torso, and between the legs, so the model has room to move them independently. A figure cropped at the knees gives you very little to animate below the knees.
Even line weight and a readable head shape. Keep the stroke consistent across the whole drawing, no thick torso and hairline arms. The head should read as a distinct circle from a distance. If the head merges into the neck or shoulders, the first thing that goes wrong in the render is the head.
Match the aspect ratio of the target video. Every shot can be 16:9, 9:16 or 1:1, and the anchor should already be in that shape. Handing a wide image to a vertical render forces a crop or a stretch, and either one changes the character you worked to pin down. If you are planning a 9:16 sequence, prepare the anchors in 9:16 from the start.
Set the style. The five styles carry different visual language: Minimal (black on white), Midnight (white on near-black), Pop (red beanie, yellow tee), Prehistoric (charcoal on parchment), Cozy (warm daylight interior). Name the same style in every prompt so the renderer is not reinterpreting the look shot by shot.
Your director's desk
Paste the script. Pick a stickman style. The director cuts it into shots and renders each one with Seedance 2.0. Planning is free — you only spend credits when you render.
1–400 words. One idea per shot works best.
Optional. Upload a stickman frame or paste a public image URL and the shot starts from it.
Credits are charged only when a shot starts rendering. A failed render is refunded automatically.

When to use text to video instead
The anchor is not always the right tool. Three cases where text-to-video is the better start.
A brand-new character with no reference. If you have no drawing yet, there is nothing to upload. Render a text-to-video shot, look at what comes back, and if the character works, save a frame from it as your anchor for the rest of the sequence. The first render becomes the reference instead of the exception.
A shot where composition matters more than identity. A wide establishing shot of a stick figure on an empty horizon is mostly about framing. Insisting on a strict anchor there can fight the composition you want. Describe the shot, and save the anchor for the close, character-led shots where identity is actually visible.
Fast exploration before committing to a design. Planning a shot list is free, and credits are charged only when a shot starts rendering. That makes it cheap in attention to try several directions in text before you commit to one drawing. Render a couple of short, low-resolution tests, pick the direction, then draw the anchor properly. Don't build a six-shot sequence around a character you have not looked at yet.
A consistency checklist
Run this before every sequence. It takes a minute and saves a re-render.
Same style name in every prompt. Write it identically each time. "Minimal, black on white" in shot one and "minimal style" in shot three are two different instructions.
Same anchor image. The same file, every shot that features that character. If you make a new anchor, make it a deliberate replacement, not an accident.
Same resolution and aspect ratio. Shots can be 5, 10 or 15 seconds at 480p, 720p or 1080p, in 16:9, 9:16 or 1:1. Mixing frame shapes mid-sequence changes how the character is framed even when the drawing is identical. Duration can vary between shots, since cost scales with duration and a 5-second cutaway at 480p is a sensible place to save credits, but keep the frame shape fixed.
Review the first frame of every render before generating the next. This is the step people skip. Watch the opening second. If the line weight has thickened or the head has gone oval, fix the prompt or the anchor before you render shot three. A drifted shot caught early is a cheap fix; one discovered after six renders is not.
Rendered shots land in your video library at /settings/videos and download as MP4, so comparing opening frames side by side is easy. Line up the first seconds of all your shots and check the head shape and stroke weight match. For prompt wording that holds up across shots, the stickman video prompt guide goes deeper. And if you are weighing credit packs against plans, pricing lays out the monthly, yearly and one-time options: monthly credits expire at the end of the monthly period, yearly credits at the end of the year, one-time credits never expire, and credits that expire soonest are spent first.
FAQ
What image formats can I upload?
JPG, PNG and WebP up to 8 MB.
Can I use a photo as the first frame?
You can upload one, but the workflow is designed for stickman frames. A photo will pull the render toward photorealism, which usually does not sit well next to drawn stickman shots. A clean line drawing holds the style better.
Does image to video cost more?
No. The price depends on resolution and duration, not on the input type. A default 720p, 10-second shot is 30 credits whether it starts from text or an image. At 10 seconds, 480p is 15 credits and 1080p is 60. Text and image inputs are screened by a moderation service before a render starts, and a failed render is refunded automatically.
Can I animate an existing comic panel?
Yes, if the panel has a clear subject and enough space around the limbs. Tight crops and busy backgrounds give the renderer little to work with. If the panel is close to what you want but cropped, extend or redraw it into a full-body anchor first.
