-----------------

Per i video a 4K youtube riserva ben 20mbps.
Per quelli a 2.7K parliamo di meno di 6mbps.
Per i 1080 non arriva a 4mbps.
Per i 720 a 2mbps.

------------------

I video a 4K riesco a vederli senza problemi su un PC con I7 32Gb RAM e Geforce.
I 20mbps significano massima qualità.
Quindi secondo me sono già il futuro dello streaming online.
Consiglio l'ottimo zoom player per guardarli in remoto, è molto fluido anche su pc non potenti.

ATTENZIONE!!!

Magari sbaglio ma sul sito http://it.shop.gopro.com/hero4 parla di risoluzione video, per la Silver, a 1080p e non a 4k.
Oltre ai 1080p arriva solo la black!


Confermate?
Moderatori? date un'occhiata

la hero 4 silver è diciamo come una 3+ b.e. con lcd....con qualcosina in più (Night-Photo,Night Lapse) e qualche cosa in meno (4K Super View,2.7K Super View ,2.7K 4:3) e una lente ottica diversa 4 S. (Qualità d'immagine Ultra-Nitida
Obiettivo interamente in vetro con distorsione ridotta) 3+ b.e. (Lente ultra nitida 6 lenti asferiche in vetro ƒ/2.8,
Ultra grandangolo con minore distorsione)........cmq molto simili infatti secondo me e per quello che hanno messo fuori produzione la 3+ b.e senò si ritrovavano fuori 2 camere quasi uguali....

Cioè hanno tolto il 4k e 2k sulla silver?? Capisco che avevano pochi frame ma erano gran belli!!

[Perry97]

Non capisco. Lo Shop gopro da registrazioni fino a 1080p. Gocamera dice sia 4k che 2k ma senza superview per entrambi. Sapete qualcos altro?

Qualcuno ha giá postato questo video di mic?

Solo io non noto differenze, anzi, in alcuni casi sembra piú performante la 3+?
