File video di 3 fonti diverse , come decidere il migliore?
Ciao a tutti , ho 3 file video provenienti da fonti diverse, ho usato mediainfo per capire quali tra i tre sia migliore e da salvare, ma a parte l'audio(semplicemente tutto in AAC quindi controllo i kbps) per la parte video ci sono un po' troppe differenze (frame per secondo-> importanti ma anche la risoluzione video è importante quindi non saprei cosa prendere in considerazione).
Mi dareste una mano indicandomi anche il motivo della vostra scelta?  1. Codice:

Scegli la traccia video che a schermo intero si vede meglio e la traccia audio che si sente meglio, e le rimuxi con mkvmerge.
