Videos konvertieren kann eine ziemlich langwierige Geschichte sein. Da die Hosting Platform, welche ich betreibe nachhezu unausgelastet ist dachte ich mir, wieso nicht mal eine 8 Core Virtual Machine erstellen und ein bisschen Spass haben. Gesagt, getan: das Resultat war überwältigend!

Für den gleichen Film auf meinem Pentium 4 3200 zu konvertieren (20 Stunden) brauchte ich auf dem 8 Core System 2 Stunden. 8core_converting.png
