Testing contract

Reference control

Scenario: Parse the FCPXML project document and resolve its declared timeline rate and duration.
Expected result: Variant 11 resolves to a 24 fps, two-second timeline and keeps its reference identifier without being treated as browser-playable media.

What is a .fcpxml file?

FCPXML is Apple's XML interchange format for Final Cut Pro libraries, events, projects, timelines, resources, effects, and metadata. Time values are commonly expressed as rational seconds, resources are declared once and referenced by identifier, and the document version controls which elements and attributes an importer may accept.

How to use this file

Use an example .fcpxml file to test XML validation, resource relinking, rational-time conversion, connected-clip placement, role metadata, and rejection of references that point to an undeclared asset.

How to use this file for testing

“Creator Timeline FCPXML 11” is a deterministic Novus Examples fixture for Timeline testing, Video editing, Serialization testing. Equivalent deterministic edit decisions and project structures across common timeline formats, with expected clip order, timing, transitions, and failure behavior.

Documented properties for this file: FCPXML · 439 bytes. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.

Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.

Playable creator clips use their measured duration and catalog thumbnail on a watch-first page. Timeline, caption, sync, colour, and failure sidecars remain download-only; compare their ordered decisions and expected outcome rather than assuming every creator format is browser-playable.

Relink the declared local assets, preserve rational or frame-based timing, and compare the resulting clip order, transitions, duration, and sync markers with the expected contract.
