Correction, 2026-10-02: this page said free plans are "usually" watermarked or non-commercial; it now says what Kling and Pika actually list. Kling's free Basic plan has no monthly credits (Kling's daily login credits are for subscribers, during events), and Pika's free plan is packs only. It also stated as fact behaviour we never measured: cartoon as "the easiest thing" to ask of a video model, hands and two interacting characters as "the reliable" failures, side views that "will differ", and 480p as "usually" enough. Those are now things to check in each take. The cheapest full workflow left out Pruna p-video Draft, which animates a start image for 4 credits per 5 seconds at 720p. And the copyright section treated prompting a living artist's style as the same infringement question as copying a studio's characters; it is a different question, and we now simply advise against it. We also added that Merge Videos returns the joined clips without sound.
Correction, 2026-10-01: this page listed base Wan 3.0 reference-to-video, 34 credits for 5 seconds at 480p, as the cheapest way to carry a design forward and as a canvas route for animating from a reference. On the canvas, base Wan 3.0 animates one start image and takes no reference images; its 34-credit reference-to-video mode exists only through the 8frame MCP connector and starts from a reference clip. The cheapest reference-image route on the canvas is Grok Imagine's reference mode, from 35 credits for 5 seconds at 480p. We also cited Kling's credits policy for its free plan being watermarked and non-commercial (those facts are on Kling's video generator page and in its terms of service), labelled Kling v3 Standard as the route for a controlled camera move, which we never measured, and gave a six-shot total of roughly 300 credits without a breakdown, which is now added (310).
Cartoon and stylised output is a forgiving place to start with AI video, for a structural reason: the uncanny valley is a photorealism problem. Flat shading, simplified anatomy and exaggerated motion are a visual grammar with less detail to get wrong, so a small artefact that would ruin a realistic clip can read as style. Check every take anyway.
The hard part is not the look. It is keeping the same character across shots.
TL;DR
- Free plans: Kling's free Basic plan lists no monthly credits, and its free output is watermarked and not for commercial use; Pika's free plan has no watermark, but also no monthly credits (packs only) and no commercial licence
- Cheapest paid route: Pruna p-video Draft at 4 credits per 5 seconds (720p), from text or a start image; Wan 3.0 at 480p is 24 if you want Wan
- Stylised is forgiving because flat shading leaves less detail to get wrong; still check every take
- Character consistency is the real problem, so lock the design in a still first and start every shot from it
- Reference images: on the canvas the cheapest route is Grok Imagine's reference mode, 1 to 10 images, from 35 credits for 5 seconds at 480p. Base Wan 3.0 takes one start image, not references
Why cartoon is the forgiving mode
Flat colour has less to keep consistent. Photorealistic lighting must stay physically coherent frame to frame. Two or three flat tones leave far less to track.
Simplified hands. Cartoon hands are already simplified shapes, four fingers and no detailed knuckles, so there is less anatomy to get wrong. Check them in every take all the same.
Exaggerated motion is the style. Squash, stretch and impossible arcs read as craft rather than as error.
Held frames are legitimate. Limited animation is a real technique, so a clip that does not move constantly looks intentional.
The workflow
Do not prompt straight to video. Keeping one character consistent is the hard part, and a text-only prompt leaves the model free to redesign the character in every shot.
- Design the character as a still. Seedream 5 at 6 credits. Iterate until the design is right; twenty attempts cost 120 credits, about $1.20.
- Write the character block. A paragraph describing the design exactly: proportions, palette, clothing, line weight. Paste it unchanged into every subsequent prompt.
- Animate from that still. Wan 3.0 at 480p, 24 credits per 5 seconds, using the approved frame as the first frame. Pruna p-video Draft also takes a start image, at 4 credits per 5 seconds (720p).
- Reuse the same frame every time. Each new shot starts from the approved design, not from the previous clip.
About 30 credits per shot on Wan 3.0, thirty cents; about 10 with p-video Draft.
What it costs
Canon 8frame prices, a credit is $0.01 at pack rate:

| Illustrative, non-photoreal still | Midjourney V8 (job of four) | 32 |
| Animate, 5s at 720p, from text or a start image | Pruna p-video Draft | 4 |
| Animate, 5s at 480p | Wan 3.0 | 24 |
| Animate from reference images, 5s at 480p | Grok Imagine reference mode (1 to 10 images) | from 35 |
| Animate, 5s at 720p | Wan 2.2 | 50 |
| With generated audio, 8s | Veo 3.1 Lite | 54 |
| Animate a still on Kling, 5s at 720p (start image required) | Kling v3 Standard silent | 57 |
| Long single take, 30s at 480p | Wan 3.0 base | 142 |
| Assemble the shots | Merge Videos | 10 |
A six-shot cartoon sequence with a designed character: twenty design attempts on Seedream 5 (120), a still per shot (36), six 5-second Wan 3.0 clips at 480p (144) and one merge (10) come to 310 credits, about $3.10, before any re-runs. Merge Videos joins the picture only: the merged file has no sound, so music, voices and effects go on the timeline of 8frame's Video Editor mode or in your own editor.
What to check in every take
Character drift. A reference frame does not guarantee that side and three-quarter views still match the design. Compare each take with the approved still, and build sequences from shots that reuse similar angles.
Two characters interacting. Watch for bodies passing through each other and for one design bleeding into the other. Where you can, stage the shot so only one character moves.
Lip sync to dialogue. This workflow has no lip-sync step. Either avoid visible speech, cut away during lines, or keep mouths simple and rhythmic rather than phonetic.
Text in frame. Signs and titles can garble once they move. Add type in the edit.
Long-form. A full animated short needs consistency, dialogue and staging together, and this workflow does not cover all three at once. Plan short sequences.
The copyright line
Do not reproduce an existing studio's characters. They are copyrighted and immediately recognisable, and generating them for anything public is a straightforward infringement question rather than an interesting edge case. Keep named living artists out of your prompts too.
Describing a technique is legitimate. Naming a property or a person to copy is not.
FAQ
Can I turn a photo of myself into a cartoon video? Technically yes. For a real person, only with their permission, and compare the likeness with the photo in every take.
Why does my character keep changing? Because nothing carries the design forward unless you make it. Lock it in a still and reuse that frame as the first frame of every shot.
Is 480p enough for cartoon? Test it before you commit: a 5-second Wan 3.0 shot at 480p is 24 credits, so run one and watch it at the size it will play. If it looks soft, Wan 3.0 at 720p is 48 for 5 seconds. Generate at delivery resolution, since 8frame has no video upscaling.
What is the cheapest full workflow? Design at 6 credits, animate from that still on Pruna p-video Draft at 4 per 5 seconds (720p) or on Wan 3.0 at 480p at 24, merge at 10.
Does Kling give free daily credits? Not to free accounts. Kling's credits policy says that during events "Kling subscribers can claim daily credits upon login/refresh", with amounts set by platform announcement, and Kling's plan table lists no monthly credits on the free Basic plan.
