This adds an article, "Normalize the Loudness of a Folder of Videos with PowerShell and FFmpeg", and my author profile (made with
tools/new-author.ps1).The article builds an advanced function that measures every video in a folder with FFmpeg's two-pass
loudnormfilter. It normalizes the files that miss the target inForEach-Object -Parallel, supports-WhatIf, skips files that are already within tolerance, and re-measures what it writes. It also covers the problems I ran into: reading theloudnormreport from stderr,$using:and runspace scope in-Parallel, a colon after a variable inside a string, and whenloudnormfalls back from linear to dynamic mode.I drafted this with Claude Code; every command in it was run on PowerShell 7.6.9 with FFmpeg 9.0.2, and the output shown is from those runs. PSScriptAnalyzer reports no findings for the function, and the site builds with Hugo 0.155.1 with
validate:articlespassing.It's dated for today; happy to move it to whatever date suits the schedule.
