AI video fails in specific ways. The failure is rarely random; it usually comes from the photo, a contradictory prompt, an overloaded scene or a provider limit. This page lists the problems people actually hit with the Crazy Frog AI chase, in the order they appear, and the first fix for each.
1. The face drifts or changes mid-clip
What it looks like: the rider starts as you and ends as a similar-but-different person. The jaw, eyes or hairline shift between shots.
Why it happens: the model has too little identity information, or the clip has too many frames for the reference to hold. A soft, dark or heavily filtered photo is the usual cause.
Fix: use a sharper, front-facing, evenly lit portrait with no filter. Shorten the clip. If the face still drifts, try a wider shot so the face occupies fewer pixels and the model has less to invent.
2. A motorcycle appears under the rider
What it looks like: a wheel, a seat, a frame or handlebars materialize. The joke collapses because the bike is visible.
Why it happens: the prompt mentions a motorcycle without a strong negative instruction, or the reference clip contains a bike. The model follows the most concrete noun.
Fix: keep the only visible bike under the chaser. Add “no visible motorcycle, wheels, frame or handlebars under the rider” to the prompt. Remove any line that describes the rider’s bike as an object. If you are using a reference clip, choose one where the bike is already invisible.
3. Hands look wrong
What it looks like: extra fingers, fused hands, or fists that melt when the rider grips the invisible handlebars.
Why it happens: hands are small, fast-moving and often occluded. Current video models are weak at them.
Fix: do not frame the hands in a close-up. Use a wider tracking shot, shorten the clip, or choose a style where the hands are less prominent. A prompt that says “fists out” is enough; do not ask for finger detail.
4. The chaser does not look like the second photo
What it looks like: the friend you uploaded becomes a generic cop, or a blend of both faces.
Why it happens: the second photo is dark, small, turned away, or visually similar to the first. The model has weak identity signal and falls back to the “cop” concept.
Fix: use a brighter, front-facing second photo with a distinct outfit. Make the role sentence explicit. If the likeness still fails, leave the slot empty and let the model generate a cop; a clean generated chaser is better than a bad likeness.
5. The roles are swapped
What it looks like: the chaser does the flip, or the lead rider appears on the hover-bike.
Why it happens: the prompt names the roles but does not forbid swapping, or the first slot contains the wrong person.
Fix: add “the person in the first reference photo is the lead rider; do not swap their roles” to the prompt. Double-check the upload order. If the model still swaps, regenerate with a shorter clip.
6. The render fails immediately
What it looks like: the task moves to failed within seconds, and the credits return.
Why it happens: the input was rejected by moderation, the prompt was too short, or the uploaded file was not a valid image.
Fix: read the error message. A moderation rejection will fail again with the same input; change the photo or the prompt. A short prompt needs more description. A file error means re-upload a JPG, PNG or WebP under 10 MB.
7. The render is stuck in processing
What it looks like: the status stays on processing longer than expected.
Why it happens: the provider queue is busy, or the task is waiting on a worker. The studio polls the real status; it does not invent a percentage.
Fix: leave the page and check My videos later. Do not start a second render for the same clip; that charges again. If the task is still processing after a long wait, contact support with the task ID.
8. The clip is too short or too long
What it looks like: the chase is cut before the flip, or the ending drags.
Why it happens: the duration was changed without changing the prompt. The four beats need enough time to land.
Fix: use the style’s default duration for the first run. If you shorten the clip, remove a beat rather than compressing all four. If you lengthen it, add a beat (a look back, a wider getaway) instead of stretching the existing action.
9. The result looks “AI” in a way you cannot name
What it looks like: the clip is technically correct but feels synthetic: the light is too even, the motion is too smooth, the background is too clean.
Why it happens: the model optimizes for a plausible frame, not for the imperfections of real footage. A clean prompt produces a clean image.
Fix: add texture to the prompt: “handheld camera, slight motion blur, practical street lights, film grain”. A little imperfection reads as real. Do not overdo it; a prompt full of camera jargon can produce a worse result than a simple one.
When to stop retrying
If three renders with different photos and prompts fail in the same way, the problem is probably the format, not your input. Try a different style, a shorter clip, or a text-to-video prompt. A different scene can succeed where the original keeps failing.
A note on refunds
Failed renders return their credits automatically. A successful render that you downloaded is not refundable. If a failure did not return credits, contact support with the task ID and the time; the credit ledger can be checked.
