Testing contract
Reference control- Scenario
- Decode the PNG without colour correction and sample the centre pixel of every 24-pixel stripe.
- Expected result
- Eight deterministic RGB stripe samples are returned for variant 10, and the image remains exactly 192x108 with no alpha channel.
What is a .png file?
PNG (Portable Network Graphics) is a raster image format using lossless DEFLATE compression. It supports full 8- or 16-bit-per-channel truecolor, palette, and greyscale modes with an optional alpha channel, but no animation. It is the standard choice for screenshots, logos, and graphics with sharp edges or transparency.
How to use this file
Use an example PNG to test image decoders, alpha-compositing, thumbnail generators, and format converters, or to verify that a pipeline preserves transparency and color depth on round-trip.
How to use this file for testing
“Video Colour Reference 10” is a deterministic Novus Examples fixture for Video QA, Colour management, Visual diff / regression. Short 270p clips with known scene cuts, freezes, black frames, flash frames, and burned-in captions — for detection and QC tooling.
Documented properties for this file: PNG · 942 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.
