metriccompare

Documentation

Overview

metriccompare scores (source, distorted) video pairs with CVVDP and/or SSIMU2 through libvship. It is research tooling for comparing the two metrics against each other, not a production Reel code path.

Jobs mode scores a batch of (source range, distorted encode) pairs and writes a JSON report:

metriccompare --jobs jobs.json --out results.json [--metrics cvvdp,ssimu2] [--per-frame] [--display display.json]

GPU micro-benchmark mode decodes a fixed set of frames once, then times repeated metric compute calls only, to isolate GPU metric throughput from decode:

metriccompare --gpubench --src X --dist Y --start N --frames 48 --reps 20 [--crop W:H:X:Y] [--metrics cvvdp,ssimu2]
