Multimedia Interpolate (oridecon-multimedia-interpolate)

Video frame-rate interpolation for the Oridecon Framework — a local RIFE reference-server backend that doubles or quadruples a clip’s frame rate by synthesizing midpoint frames.

Overview

oridecon-multimedia-interpolate synthesizes intermediate frames between two input frames (or between frames of a video) using a RIFE reference server, and registers a VideoInterpolationService for frame-level video interpolation when a VideoProcessor is available in the container.

Install

uv add oridecon-multimedia-interpolate
# Optional extras
uv add "oridecon-multimedia-interpolate[rife-server]"  # RIFE server deps (torch)

Quick Start

from oridecon import Application
from oridecon.di.module import Module, module
from oridecon.multimedia.interpolate import InterpolationModule
from oridecon.contracts.multimedia.protocols import InterpolationProvider
from oridecon.contracts.multimedia.types import InterpolationRequest, MediaAsset


@module(imports=[InterpolationModule.configure()])
class AppModule(Module):
    pass


async def main() -> None:
    async with Application.boot(modules=[AppModule]) as app:
        interpolate = await app.container.resolve(InterpolationProvider)
        frame_a = MediaAsset(
            mime_type="image/png", provider="local", bytes_data=b"<png>"
        )
        frame_b = MediaAsset(
            mime_type="image/png", provider="local", bytes_data=b"<png>"
        )
        result = await interpolate.interpolate(
            InterpolationRequest(frame_a=frame_a, frame_b=frame_b)
        )
        if result.is_ok():
            midframe = result.unwrap()  # MediaAsset — synthesized midpoint frame


if __name__ == "__main__":
    import asyncio

    asyncio.run(main())

Configuration

Zero-config usage: Call InterpolationModule.configure() with no arguments to use the rife backend at http://localhost:5500.

Option 1 — YAML file

multimedia:
  interpolate:
    backend: "rife"

Option 2 — Profiles + Environment Variables

export ORI_PROFILE=production
export ORI_MULTIMEDIA__INTERPOLATE__BACKEND=rife

Option 3 — Python

from oridecon.multimedia.interpolate import InterpolationModule
from oridecon.multimedia.interpolate.config import InterpolationConfig

InterpolationModule.configure(config=InterpolationConfig())

Interpolation is frame-pair based — InterpolationRequest(frame_a=..., frame_b=...). There is no configurable factor; InterpolationConfig only carries backend, rife_base_url, and timeout.

Config reference

Field	Default	Env var	Description
`backend`	`"rife"`	`ORI_MULTIMEDIA__INTERPOLATE__BACKEND`	`rife`
`rife_base_url`	`"http://localhost:5500"`	`ORI_MULTIMEDIA__INTERPOLATE__RIFE_BASE_URL`	RIFE server URL
`timeout`	`15.0`	`ORI_MULTIMEDIA__INTERPOLATE__TIMEOUT`	Request timeout in seconds

Module Factory Methods

Method	Description
`InterpolationModule.configure(config)`	Configure with explicit interpolation config
`InterpolationModule.stub()`	Real module pinned to the default `rife` backend for tests

Key Features

RIFE backend — state-of-the-art frame interpolation via a local reference server
Video interpolation — VideoInterpolationService for frame-level video interpolation (when VideoProcessor is available)
Reference server — oridecon-interpolate-rife-serve console script runs the RIFE model server
Result-based — interpolate() -> Result[MediaAsset, MultimediaError]; errors are domain values, not exceptions

Testing

from oridecon import Application
from oridecon.multimedia.interpolate import InterpolationModule


async def test_boot():
    async with Application.boot(modules=[InterpolationModule.stub()]) as app:
        assert app.container is not None
