Documentation

Overview

aligncheck reproduces and locates the scoring frame-misalignment bug.

It decodes a source file sequentially as ground truth (frame N -> luma checksum), then for a set of target frames calls ReadFrame(N) on a FRESH video.Source -- the seek-based access pattern reel's CVVDP scoring and fullvalidate use -- and reports any frame whose ReadFrame checksum does not match the ground truth, including how many frames off it landed. Repeats each probe to expose run-to-run nondeterminism.

Usage: go run ./scripts/aligncheck <video.mkv> [reps]
