Firefly video used my credits without generating video

I was generating a video using Seedance 2.5, but after generation was failed 570 credits were used and didn’t refund.

I’m using Chrome browser (it was updated to Version 154.0.8037.58 (Official Build) (64-bit) right before starting generation), OS: Windows 11.

And it didn’t appear in generation history

The prompt I used: 

Use Reference Image 1 as the EXACT FIRST FRAME of the video but remove red doodle lines on the eyes of people.
Use Reference Image 2 ONLY as a visual reference for the appearance, mechanical construction, armor arrangement, proportions, color palette, pineapple-themed robot design and combat poses of the transformed pineapple robots.

Do NOT use Reference Image 2 as a second keyframe or temporal frame.
The video must continuously transform the living performers from Reference Image 1 into the pineapple robots represented by Reference Image 2.

Create a 6-second continuous ultra-photorealistic live-action video of a Sinulog festival in Cebu, Philippines.

FIRST FRAME — 0.00 seconds:
The first frame must be visually identical to Reference Image 1.

Preserve the exact festival environment, road, crowd, trees, decorations, stage structures, parade formation, lighting, perspective, camera position, costumes and composition of Reference Image 1.

The performers are wearing elaborate pineapple-themed Sinulog costumes made from natural pineapple leaves, dried plant material, layered skirt fringe, decorative pineapple elements and elaborate pineapple-leaf headpieces.

The man visible in the bottom-right corner of Reference Image 1 must naturally leave the frame during the beginning of the video and must NOT be present afterward. His disappearance must happen through normal movement out of the camera frame, not through morphing or teleportation.

0.00–1.00 seconds:
The Sinulog parade continues naturally.

The pineapple-costumed performers begin reacting to something unexpected. Their movements become synchronized. They stop their normal parade movements and gradually assume strong defensive combat-ready poses inspired by the robot poses shown in Reference Image 2.

The crowd notices that something unusual is happening.

The camera remains handheld and observational, with subtle realistic human camera movement, natural framing imperfections and authentic live-event footage characteristics.

1.00–3.80 seconds:
The pineapple costumes begin transforming into highly realistic mechanical pineapple robots.

The transformation must happen DIRECTLY from the physical costume elements visible in Reference Image 1.

Nothing simply disappears.

The transformation is a continuous, physically coherent mechanical conversion.

The long hanging strips and fringe from the original pineapple costumes detach naturally from the performers and fall downward under gravity.

Individual pineapple leaves from the costumes and leaves attached to the performers' headpieces detach and fall realistically onto the road.

The falling leaves and skirt fringe remain visible on the asphalt after falling.

As the organic costume elements fall away, realistic mechanical components emerge and assemble underneath them.

The robot transformation must resemble a complex practical mechanical transformation rather than magical morphing.

Mechanical components visibly move into position:
panels rotate,
armor plates unfold,
segments slide,
joints articulate,
mechanical limbs extend,
small components lock together,
shoulder armor rotates into place,
chest armor assembles,
leg armor reorganizes,
forearm components lock together,
feet mechanically reshape,
and pineapple-shaped armor sections align into the final robot configuration.

Every robot component must have a believable mechanical origin and trajectory.

The final robot design, armor arrangement, proportions, colors, pineapple textures, mechanical joints and combat-ready poses must closely match Reference Image 2.

The transformation must preserve conservation of matter:
no body parts or costume pieces simply vanish,
no robot components appear from nowhere,
no objects teleport,
no instant magical morphing.

The original performers physically transform into the robot structures through visible mechanical assembly.

3.80–5.00 seconds:
The transformation reaches its final stage.

The remaining pineapple leaves and skirt fringe detach and fall onto the road.

Some individual leaves bounce naturally on the asphalt before settling.

The last mechanical panels rotate and lock into place with believable mechanical inertia.

The transformed performers now stand as fully realized pineapple robots matching the visual design and combat-ready poses of Reference Image 2.

The robots should feel physically heavy.

Their feet make realistic contact with the asphalt.

Their bodies have believable mechanical weight, balance, inertia and joint articulation.

5.00–6.00 seconds:
The fully transformed pineapple robots hold their strong combat-ready poses.

The surrounding crowd reacts with genuine surprise and excitement.

People cheer, shout and raise their phones to record the unexpected transformation.

Some spectators step backward while others lift their smartphones higher.

The atmosphere becomes energetic and chaotic, but the parade environment remains realistic and physically consistent.

The road in the foreground and around the robots is now visibly covered with fallen pineapple leaves and detached strips of the original costume skirts.

CAMERA:
Authentic handheld smartphone/event-camera footage recorded from within the Sinulog crowd.

Natural human-operated camera movement.
Subtle handheld shake.
Minor framing imperfections.
Realistic autofocus behavior.
Natural exposure adaptation.
Realistic motion blur.
Natural depth of field.
No cinematic crane movement.
No drone shot.
No impossible camera movement.
No artificial camera orbit.

Maintain the original perspective and general composition of Reference Image 1 throughout the transformation.

REALISM:
Extremely photorealistic live-action footage.

The scene must look like a real Sinulog parade accidentally capturing an impossible but physically convincing mechanical transformation.

Real human skin.
Real fabric.
Real pineapple leaves.
Real dried plant fibers.
Real asphalt.
Real sunlight.
Real shadows.
Real mechanical surfaces.
Real reflections.
Realistic crowd behavior.

The robot materials must have physically believable metal, painted armor, mechanical joints, fasteners, hinges, pistons and moving panels.

Avoid the appearance of CGI, videogame graphics, animation or cartoon imagery.

TRANSFORMATION PHYSICS:
The transformation is the central visual event.

Every visible transformation step must have a physical cause.

Pineapple leaves detach because the costume structure opens.
Skirt fringe falls because its attachment points release.
Decorative pineapple elements separate from the costume and become integrated into mechanical armor structures.
Mechanical armor plates emerge from the underlying costume structure and fold into position.
Mechanical joints rotate and lock.
Parts collide and interact with realistic physical constraints.

No element should disappear without an observable physical explanation.

The falling organic costume material must remain in the environment after the transformation.

ROBOT DESIGN:
Use Reference Image 2 as the primary visual reference for the final pineapple robots.

Match its:
overall silhouette,
pineapple-shaped armor,
golden-orange pineapple armor surfaces,
green leaf-like armor elements,
mechanical limb structure,
robotic joints,
head design,
shoulder armor,
chest armor,
forearm armor,
leg armor,
foot design,
proportions,
combat stance and overall visual identity.

However, integrate these robot characteristics naturally into the real-world Sinulog environment from Reference Image 1.

The robots must NOT look like people wearing robot costumes.
They must appear to be fully assembled mechanical pineapple robots.

CROWD:
The crowd consists of real festival spectators.

As the transformation happens, their reactions develop naturally:
initial curiosity,
surprise,
then cheering and excitement.

Several people visibly raise smartphones to record the robots.

The crowd must remain composed of realistic individual people with natural independent movements.

No duplicated crowd figures.
No frozen crowd.
No synchronized artificial crowd animation.

ENVIRONMENT:
Preserve the Sinulog festival setting from Reference Image 1.

Maintain the road markings, trees, decorations, parade structures, crowd barriers, colorful festival elements and overall daytime outdoor atmosphere.

The fallen pineapple leaves and costume fringe accumulate naturally on the asphalt.

They must remain physically present after falling.

AUDIO:
Authentic diegetic Sinulog festival sound.

Large outdoor crowd ambience, distant festival music, parade noise, people talking and cheering.

During the transformation, add realistic mechanical sounds synchronized with visible movements:
metal panels sliding,
mechanical joints rotating,
small components locking,
hinges moving,
armor plates snapping into position.

Do not make the mechanical sounds excessively cinematic.

As the robots finish transforming, the crowd erupts into loud cheers and surprised reactions.

No narration.
No voice-over.
No subtitles.
No background music added separately from the diegetic festival environment.

NEGATIVE CONSTRAINTS:
No use of Reference Image 2 as a second temporal frame.
No sudden scene change.
No cuts.
No teleportation.
No magical transformation.
No disappearing costume elements.
No disappearing leaves.
No disappearing skirt fringe.
No robot parts appearing from nowhere.
No duplicated robots.
No duplicated limbs.
No extra arms or legs.
No anatomical deformation.
No floating mechanical parts without physical support.
No rubbery mechanical movement.
No cartoon.
No anime.
No videogame graphics.
No stylized CGI.
No futuristic sci-fi city.
No change of location.
No change of weather.
No change from daytime to nighttime.

The final result should look like an extremely realistic live-action recording of a real Sinulog parade in which the pineapple-costumed performers physically and mechanically transform into the pineapple robots shown in Reference Image 2.
