About The Project

This as a .aep (After Effects Project) parser in Python. After Effects files (.aep) are mostly binary files, encoded in RIFX format. This parser uses Kaitai Struct to parse .aep files and return a Project object containing items, layers, effects and properties. The API is as close as possible to the ExtendScript API, with a few nice additions like iterators instead of collection items.

Usage

import aep_parser

# Parse an After Effects project
app = aep_parser.parse("path/to/project.aep")
project = app.project

# Access application-level info
print(f"AE Version: {app.version}")

# Access every item
for item in project:
    print(f"{item.name} ({type(item).__name__})")

# Get a composition by name and its layers
comp = next(c for c in project.compositions if c.name == "Comp 1")
for layer in comp.layers:
    print(f"  Layer: {layer.name}, in={layer.in_point}s, out={layer.out_point}s")

    # Access layer's source (for AVLayer)
    if hasattr(layer, "source") and layer.source:
        print(f"    Source: {layer.source.name}")
        # Get file path if source is footage with a file
        if hasattr(layer.source, "file"):
            print(f"    File: {layer.source.file}")

# Access render queue
for rq_item in project.render_queue.items:
    print(f"Render: {rq_item.comp_name}")
    for om in rq_item.output_modules:
        # Settings are a dict with ExtendScript keys
        video_on = om.settings.get("Video Output", False)
        print(f"  Output: {om.name}, video={video_on}")
