Cinerr Stats Dashboard

Features

Everything you need to
understand your media.

01
Stats Dashboard
See exactly what your library is made of: how many files are AVC vs HEVC, which are HDR, what resolutions you have, and how much space you'd free by transcoding. No guessing, no digging.
02
Media Browser
Search, sort, and filter every file by codecs, resolutions, HDR, audio tracks, file sizes, and more.
03
Smart Scanning
The first scan reads every file. Every rescan after that finishes in seconds, even on libraries with tens of thousands of titles.
04
Live Progress
Start a long-running job and walk away. Pause it when you need the resources back, resume it later, or cancel it outright.
