ich werf mal meine Batch in den Raum die ich für reencode nehme
Bei mir sieht es so aus:
Filmeordner/Filmename/filmname.mkv
im Filmeordner liegt die ffmpeg.exe, ffprobe.exe und das batch script unten
-> minfilesize = Mindestgröße für ne mp4 / mkv für reencode
Gibt es einen Hit, also eine Datei die ein Reencode ausgehend ihrer Größe braucht, dann fertige ich ein Sample an. Ab Minute 25:00 ein 1 Min langes Sample um die Quali etwas anzugleichen je nach "Grain".
Zudem konvertiere ich nur wenn der Film nicht schon im Encode ist (.lck Datei existiert)
cfr wird also je nach Sample Größe variiert.
Nach dem Sample wird der Film bei mir nach D:\Temp kopiert, da gewandelt, das Ergebnis zurückgespielt.
HDR Metadaten muss man leider von Hand eingeben, hab keinen Weg gefunden das automatisch zu übernehmen. Dazu gehört maxCll maxfall und Mastering Display
Kann man aber über set HDR=0 deaktivieren (deaktiviert by default)
10 Bit HEVC machen die Lines unten. Audio wird 1:1 übernommen, lässt sich ja aber anpassen zb auch OPUS 7.1.
