PAL o NTSC?

Messaggioda Jester86 » 10/06/2014, 7:22

salve a tutti,
volevo avere un vostro parere su questi due formati che si possono utilizzare con GoPro Hero. Sinceramente non ho ben capito la differenza... a grandi linee so che sono due differenti codifiche del colore e che il nostro paese utilizza il formato PAL.

Vorrei capire come gestire i due formati e quando mi conviene utilizzarne uno rispetto ad un altro.

Io lascio spesso PAL, però negli ultimi video che ho fatto ho notato che a 720 posso impostare solo 100 fps, per arrivare a 120 devo mettere NTSC.

Grazie a tutti

avevo già cercato, diciamo che i vari topic parlano generalmente delle risoluzioni ma non si affronta mai nello specifico il discorso PAL o NTSC. Volevo aprire un topic in cui si discuteva solo di questo per avere una maggiore chiarezza e un riferimento più specifico.

oltre al colore funzionano con frequenze differenti, NTSC è il sistema Americano e parte Asiatico che usano frequenze a 60Hz e il PAL è il sistema Europeo che usa la frequenza di 50Hz. Da qui il fatto che l'NTSC usa come frame il 30 - 60 e multipli al secondo e il PAL 25 - 50 e multipli al secondo.
Oggi è indifferente fare riprese NTSC o PAL perché le TV e PC digeriscono tutto. Solo se vuoi trasferire il video sul CD devi usare il PAL per visualizzarlo in Europa e in NTSC se lo vuoi in Usa questo perché il lettore CD funziona con differenti frequenze in base alla corrente che trova.
Per l'uso amatoriale va bene sia l'uno che l'altro, se vuoi fare degli slow motion usi NTSC che ha più frame e ti facilita il lavoro; per uso prof. meglio usare il PAL perché al 99% ti richiedono il lavoro su CD

Domanda...se registro in NTSC e poi monto con Final Cut, il programma di editing non me lo converte in automatico eliminando di fatto le differenze di frequenza?

i programmi di editing non leggono se è Pal o Ntsc, sei tu che imposti la timeline per l'editing a 25 o 30 oppure 50 o 60
