I cant generate videos in Firefly since yesterday, I do clean al cache, erase old videos and my Net is working 100% . SO i don't know why the video generation is not working at all.

Hi! :D I’ve tried everything from the simplest prompts to more elaborate ones, but nothing seems to work. Are you guys having any success generating videos? 

Prompt 1: Walking 

Prompt 2: 

ULTRA-REALISTIC GROUP WALKING — SOCK LOGIC COMMERCIAL | 4 SECONDS

Use the uploaded image as the absolute master reference. Preserve the exact composition, camera angle, people, socks, shoes, clothing, background, lighting, and colors.

ACTION — NATURAL FORWARD WALKING

A group of people walks naturally toward the camera at a relaxed, steady pace.

Each person takes realistic alternating footsteps, with slightly different timing to create an authentic group-walking rhythm.

The central person wearing turquoise mountain-pattern socks and white golf shoes takes a natural step forward, gently lifting one foot and placing it back on the ground.

The surrounding people continue walking with subtle, coordinated but unsynchronized movements.

Realistic heel-to-toe motion, natural ankle flexion, subtle fabric movement, and accurate ground contact.

The movement should feel like a real group casually walking together, not marching or posing.

CRITICAL — PRODUCT ACCURACY

• Preserve every sock's exact original design, colors, patterns, and proportions.

• Keep all original shoes, pants, and visible legs unchanged.

• Socks must remain clearly visible throughout the video.

• No extra feet, legs, shoes, or people.

• No sliding, floating, jumping, or exaggerated movements.

• No distorted ankles or unnatural foot rotations.

• No changing sock patterns during movement.

• No morphing, flickering, or artificial motion.

• Preserve realistic moving shadows.

CAMERA

Fixed low-angle camera at ground level.

No zoom, no pan, no rotation, no camera shake.

The group moves naturally toward the camera while the camera remains completely stationary.

TIMING — 4 SECONDS

0–1s: The group begins walking naturally.

1–3s: Continuous relaxed footsteps, with the central turquoise socks remaining visually prominent.

3–4s: The group continues moving forward smoothly, maintaining realistic movement and spacing.

FINAL RESULT

A clean, photorealistic commercial shot of different people walking together, showcasing colorful socks in everyday life.

Natural human movement, premium lifestyle advertising, 4K quality, vertical 9:16.
