4K video has been a hot topic this year. People may argue that they are still using full HD (1920×1080) monitors and TV. However, video processing is a bit more complicated than most of the people know. In brief, if your camera records video at 4K, you get excellent full HD.
Before the consumer 4K camera such as Sony AX100 and Panasonic GH4 arrive, I decided to use my Nikon 1 V2 to create a short 4K video clip. V2 itself does not record video in 4K format. Instead, it can shoot 40 consecutive RAW photos at 15, 30, or 60 fps. The photos are converted into video through Sony Vegas editing software. Although there are many limitations, the video quality turn out to be very good.
