FOR THE NX1
One of the revolutionary features of 4K video recording is the abil- ity to isolate high-resolution still photos from video footage. In the HD era, a single video frame generated a 2-megapixel image—fine for the web, but not much else. In the 4K
era, single frames are 8 megapixels; they can be used
in print or cropped more aggressively for digital
displays while still retaining significant resolution.
There are two principle ways to pull still frames
from your NX1’s 4K video. The most straightforward route is to review your files in-camera
and isolate your desired image using the camera’s
AMOLED display. In playback, you can advance
frame by frame through your stills and select the
frames you want to save by pausing the video and
hitting the “Fn” button or “capture” on the screen.
The virtue here is that the Exif data is saved for
each JPEG you create.
The other alternative is to import the camera’s
files into your nonlinear editor of choice, advance
the video frame by frame and export a still image.
The specifics will vary based on the editor you
use, but programs like Adobe Premiere and Final
Cut Pro make screen grabs fairly straightforward.
Generating usable stills from your 4K video
files is more of an art than a science, as it can
involve breaking a few of the sacred rules that
govern video exposure. If you’re shooting a
video, you don’t want to sacrifice your exposure
to get the best possible stills. That doesn’t mean
you can’t generate excellent images from your
4K movie files it just means you’re not optimized
to do so. But, if you’re shooting 4K video for
the explicit purpose of isolating stills, there are
a few settings you can adjust to up your odds of
capturing something exceptional.
