Why FilmGraph?

The film industry relies on dozens of incompatible formats — CCSLs in Word documents, Dialogbücher, SRT subtitles, EDLs, XML timelines, proprietary pipeline outputs. Building tools that work across these formats means spending more time parsing than analyzing.

FilmGraph is a single JSON schema that captures shots, scenes, dialogue, cinematography, characters, locations, and narrative events. Zero dependencies beyond Pydantic. One format for your entire pipeline.

{
  "schema_version": "filmgraph/v1",
  "meta": { "title": "Lost Killers", "duration": 5731.2 },
  "scenes": [{
    "id": 1, "title": "Opening", "start_time": 0, "end_time": 142.5,
    "shots": [{
      "id": "sh-001", "order": 1, "start_time": 0, "end_time": 8.3,
      "cinematography": { "shot_size": "WS", "camera_movement": "static" },
      "visual": { "description": "Wide establishing shot of Berlin skyline at dusk" },
      "audio": { "dialogue": [{ "speaker": "narrator", "text": "Berlin, 1998.", "start_time": 2.1, "end_time": 4.5 }] }
    }]
  }]
}

Install

pip install filmgraph

With importers for .docx files (CCSL, Dialogbuch, AD scripts):

pip install filmgraph[docx]

With OpenTimelineIO support (EDL, FCP XML, AAF):

pip install filmgraph[otio]

Quick Start

from pathlib import Path
from filmgraph import FilmGraph, Scene, Shot, ShotSize, CameraMovement

# Load
fg = FilmGraph.from_json(Path("movie.filmgraph.json").read_text())

# Traverse
for scene in fg.scenes:
    print(f"{scene.title} ({scene.shot_count} shots)")
    for shot in scene.shots:
        print(f"  {shot.cinematography.shot_size}  {shot.visual.description}")

# Save
Path("movie.filmgraph.json").write_text(fg.to_json(indent=2))

Controlled Vocabularies

Every categorical field uses a controlled enum with an OTHER fallback for extensibility.

Enum	Values
ShotSize	ECU · BCU · CU · MCU · MS · MLS · MWS · WS · EWS · INSERT · AERIAL · OTHER
ShotType	single · two-shot · group · over-the-shoulder · point-of-view · reaction · establishing · insert · cutaway · master · other
CameraMovement	static · pan · tilt · dolly · truck · tracking · handheld · crane · drone · zoom · whip-pan · push-in · pull-out · arc · rack-focus · steadicam · other
CameraAngle	eye-level · high-angle · low-angle · birds-eye · worms-eye · dutch-angle · overhead · ground-level · other
Transition	cut · dissolve · fade-in · fade-out · fade-to-black · wipe · match-cut · jump-cut · j-cut · l-cut · smash-cut · other

Importers

Convert industry formats into FilmGraph with a single function call:

from filmgraph.importers.ccsl import ccsl_to_filmgraph
from filmgraph.importers.srt import srt_to_filmgraph

fg = ccsl_to_filmgraph("FTR3_BloodyTennis.docx")
fg = srt_to_filmgraph("movie.srt", title="My Film")

Importer	Function	Input	Extra
CCSL	ccsl_to_filmgraph()	.docx shot lists	pip install filmgraph[docx]
Dialogbuch	dialogbuch_to_filmgraph()	German dubbing scripts .docx	pip install filmgraph[docx]
AD Script	ad_to_filmgraph()	Audio description scripts .docx	pip install filmgraph[docx]
SRT/VTT	srt_to_filmgraph()	Subtitle files	—
Pipeline	timeline_to_filmgraph()	Pipeline JSON output	—
OTIO	otio_to_filmgraph()	EDL, FCP XML, AAF	pip install filmgraph[otio]

Each importer also works as a CLI:

python -m filmgraph.importers.ccsl input.docx -o output.filmgraph.json
python -m filmgraph.importers.srt movie.srt -o subs.filmgraph.json

Build a FilmGraph Programmatically
