Function Documentation

## process_video

```python
async def process_video(
    frames: list[Path],
    config: VideoConfig,
    *,
    timeout: int = 30,
) -> VideoOutput

Process a sequence of frames into a video file.

Parameters

Name	Type	Required	Default	Description
frames	list[Path]	Yes	-	Paths to frame images
config	VideoConfig	Yes	-	Video configuration
timeout	int	No	30	Max processing time (seconds)

Returns

VideoOutput - Contains:

• video_path: Path to generated video
• duration: Video duration in seconds
• metadata: Generation metadata

Raises

Exception	Condition
ValueError	If frames list is empty
TimeoutError	If processing exceeds timeout
EncodingError	If video encoding fails

Example

from pathlib import Path
from video import process_video, VideoConfig

frames = [Path(f"frame_{i}.png") for i in range(10)]
config = VideoConfig(fps=24, resolution=(1920, 1080))

result = await process_video(frames, config)
print(f"Created: {result.video_path}")

### Class Documentation

    def __init__(
        self,
        config: GeneratorConfig,
        api_client: Optional[APIClient] = None,
    ) -> None

Generates videos from frame sequences using external APIs.

Constructor Parameters

Name	Type	Required	Description
config	GeneratorConfig	Yes	Generator configuration
api_client	APIClient	No	Custom API client

Attributes

Name	Type	Description
config	GeneratorConfig	Current configuration
api_client	APIClient	Active API client
stats	GenerationStats	Usage statistics

Methods

generate

async def generate(
    self,
    frames: list[Path],
    style: str = "default",
) -> VideoOutput

Generate a video from frames.

get_status

def get_status(self, job_id: str) -> JobStatus

Get status of a generation job.

Example

generator = VideoGenerator(config)
video = await generator.generate(frames, style="cartoon")

### Pydantic Model Documentation
```markdown
## VideoConfig

Configuration for video generation.

```python
class VideoConfig(BaseModel):
    fps: int = 24
    resolution: tuple[int, int] = (1920, 1080)
    codec: str = "h264"
    quality: int = Field(default=80, ge=1, le=100)

Fields

Field	Type	Default	Constraints	Description
fps	int	24	-	Frames per second
resolution	tuple[int, int]	(1920, 1080)	-	Width x Height
codec	str	"h264"	-	Video codec
quality	int	80	1-100	Output quality

Validators

• quality: Must be between 1 and 100

Example

config = VideoConfig(
    fps=30,
    resolution=(3840, 2160),  # 4K
    quality=95,
)
