fotoburst o video? [CHIUSO]

Messaggioda iaco29 » 17/12/2013, 17:38

Lo metto anche qui perchè magari qualcun'altro ha il solito problema in altri sport...secondo voi x riprendere tipo una sequenza di un salto con lo snow è meglio fare un video ed estrapolare le immagini o fare tipo 30 scatti in 3 secondi o la foto continua (tipo 5/10 scatti al secondo fino alla fine del salto)????
ho il telecomando quindi per quello non è un problema e naturalmente ho il cavalletto così la go pro sta ferma..ho una hero 3+ black ma togliendo i fotogrammi al video girato in 1080p 60fps non è che vengano un gran che di risoluzione..

Dipende cosa vuoi ottenere. Vuoi una sequenza di foto? la foto migliore da poter scegliere? Carpire un momento preciso? Fare uno slowmo?

diciamo che tecnicamente la 3+b offre la possibilità massima di fare 10 foto in un secondo alla massima risoluzione, sfruttando l'intera dimensione del sensore.
4096x3112 che corrisponde a 12,75MB, le foto quindi saranno in 4:3

La modalità video 4k riprende 15 foto in un secondo ma ha una risoluzione riscalata a 16:9 di 3840x2160 per una dimensione di poco più di 8MB.

Il primo formato fotografico che puoi ottenere da un video è 1440p con una risoluzione a 1920x1440 quindi 4:3 fino a 48 foto al secondo.

Quindi la massima risoluzione la avrai facendo 10 foto al secondo alla massima risoluzione fotografica.
La massima cattura video alla miglior risoluzione fotografica è l'opzione video 1440p a 48 fps.

la profondità colore per i video e per le foto è sempre 32bpp, per cui le immagini dovrebbero essere "identiche"

Per cui se il tuo amico salta 8mt su una lunghezza di 15mt avrai tempo e piacere di fare 10foto al secondo a 12mb.
se invece salta 40cm per 70cm fai prima a fare un video 1440p ultralargo a 48fps, con il "dispiacere" di avere foto più piccoline di 1/4
