allora ho preso un altro file sempre in analogico in mpeg2 di 10 mn lungo 305 mb, l'ho fatto processare a pvastumento con l'opzione make ps, il quale ha prodotto un file di 184 mb con le caratteristiche di seguito descritte ma con audio velocizzato. ho compresso il file con agk avendo come risultato un file di 105mb, purtroppo sempre con audio velocizzato.
domanda: con le nuove schede è sempre necessario il passaggio con pvastrumento, o si può comprimere in divx direttamente?
in questi topic mi sembra che affermiate che un file registrato in mpeg2 non deve essere processato da pvastr. con opzione make ps
http://www.scaistar.com/forum/v ... 9879#49879
io con autogk mi sono sempre trovato bene, ho fatto dei divx eccellenti presi da film in dvd di 6gb e trasformati in divx da 800mb, perchè adesso un filmatino di 10 mn in mpeg2 non viene compresso a dovere?
se ci sono guide aggiornate cortesemente potete darmi i link.
grazie
