Phosor AI

Generate AI videos (text-to-video, image-to-video) with optional custom LoRA styles via the Phosor AI platform.

For detailed API endpoints, parameters, pricing, and limits, see references/api.md.

Setup

1. Sign up or log in at phosor.ai
2. Go to Settings → API Keys to generate your API key
3. Set it as an environment variable:

export PHOSOR_API_KEY="your-api-key-here"

Keep your API key secret. Do not commit it to version control or share it publicly. All API calls are authenticated and billed through this key.

The CLI script is at scripts/phosor_client.py. All commands output JSON to stdout.

Local files used by the CLI:

• Writes phosor-pending.json to track pending job states locally

Quick Start

Text-to-Video

# Submit T2V job (480p, 81 frames, 16fps)
python3 scripts/phosor_client.py submit "A cat walking on a beach at sunset" \
  --width 854 --height 480 --num-frames 81 --fps 16

# Check status
python3 scripts/phosor_client.py status <request_id>

# Get result (video URL)
python3 scripts/phosor_client.py result <request_id>

Image-to-Video

Two-step flow: upload image first, then submit with the returned S3 key.

# Step 1: Upload image
python3 scripts/phosor_client.py upload-image /path/to/photo.jpg
# Returns: {"file_id": "img-xxx", "s3_key": "images/img-xxx.jpg", ...}

# Step 2: Submit I2V job using the s3_key as image_url
python3 scripts/phosor_client.py submit "The person in the photo starts dancing" \
  --image-url "images/img-xxx.jpg" --width 854 --height 480

With Custom LoRA

Upload your own LoRA model, then use it in video generation.

# Upload LoRA (two .safetensors: high_noise + low_noise)
python3 scripts/phosor_client.py upload-lora high_noise.safetensors low_noise.safetensors --name "My Style"

# Check upload status
python3 scripts/phosor_client.py lora-status <lora_id>

# Use in inference
python3 scripts/phosor_client.py submit "A person walking" --lora-id <lora_id> --lora-scale 1.0

# Or import LoRA from URLs
python3 scripts/phosor_client.py import-lora \
  "https://example.com/high_noise.safetensors" \
  "https://example.com/low_noise.safetensors" \
  --name "My Style"

CLI Commands

Job Management

Key Constraints

Resolutions (exact pairs only)

• 480p landscape — 854 × 480, max 161 frames
• 480p portrait — 480 × 854, max 161 frames
• 720p landscape — 1280 × 720, max 161 frames
• 720p portrait — 720 × 1280, max 161 frames
• 1080p landscape — 1920 × 1080, max 153 frames
• 1080p portrait — 1080 × 1920, max 153 frames

Frame Alignment

Frames must follow 1 + 4*k where k >= 1 (e.g. 5, 9, 13, ... 81, 85, ...). Server auto-aligns down.

Inference Parameters

• frames_per_second — default: 16, range: 4–30
• num_inference_steps — default: 4, range: 4
• guidance_scale — default: 1.0, range: 1.0–3.5
• lora_scale — default: 1.0, range: 0.0–2.0

Two-Step Upload Rule

Files must be uploaded before use:

1. Image → upload-image / import-image → returns s3_key → use as --image-url
2. LoRA → upload-lora / import-lora → returns lora_id → use as --lora-id

Queue Flow

PENDING → PROCESSING → COMPLETED / FAILED

The poll command checks all locally-tracked pending jobs and removes completed/failed ones.

Pricing

• 480p — $0.0002 per frame (0.002 credits)
• 720p — $0.0006 per frame (0.006 credits)
• 1080p — $0.0012 per frame (0.012 credits)
• LoRA multiplier — 1.25x

Exchange rate: 10 credits = $1 USD. Credits pre-deducted, auto-refunded on failure.
