The same footage at a ladder of quantiser settings from near-lossless down to visibly broken, each paired with its high-quality source, for testing artefact-removal models and for calibrating quality metrics against known encoder settings.
Each card starts with one representative test file. Choose a use case, search, or filter to find a specific profile; a card’s variant menu contains its related samples.

Hdr
Wide-gamut primaries with a conventional SDR transfer: wide colour without HDR. Frequently mishandled because tooling assumes BT.2020 always implies PQ or HLG. Every clip in this group carries the SAME picture and differ

The colour-patches plate with 50% of its saturation removed, leaving 50% of the original chroma. This is the faded-archive case rather than the black-and-white one: some colour information survives, so the task is restor

The detail-chart plate at CRF 28: mild artefacts. Encoded from the original frames rather than transcoded from the reference, so it carries exactly one generation of loss and the comparison is clean. On this plate the fi
