I recently returned from the 2013 National Association of Broadcasters (NAB) show, which is an annual trade show for broadcast, cinema and video production professionals to learn about the latest technology and innovations within the industry. Along with attending sessions lead by Hollywood and TV directors, cinematographers and producers, I got to learn about the latest trends in production and delivery technology on the show floor. This included the latest Ultra HD cameras, remote control helicopters, LED studio lighting, virtual sets, social media moderation for broadcast & digital signage, Steadi-Cams for iPhones, more powerful and efficient post-production software and much more. The following are three overall trends from this year's show.
Ultra HD/4K was everywhere
The hype of 3D at NAB 2012 has been replaced with Ultra HD (UHDTV) at this year's show. UHDTV is the general marketing term for 4K and 8K video resolution standards. This refers to video resolutions that are roughly four-eight times that of 1080p (full HD). You may be thinking, “my HDTV looks awesome, why would I need something better?” Take my word for it. It's noticeably better, especially on large displays. The best way I can describe it is that even close up, it looks like a fine photographic print. Although mainstream adoption of UHDTV is probably many years off (the display below costs around $20,000), eventually it will be adopted as a standard that replaces HD. That said, it does have some practical uses right now.

partnered with thunder::tech to produce a time-lapse video that captured
the excitement and activity in the aquarium during weekend opening
weekend.
Our Multimedia team set up three cameras in the aquarium that took
photos every 10 seconds and used these images to create a time-lapse video by editing them together and adding interesting facts and figures
about the aquarium throughout.

This post is going to talk about another type of 3-D: Stereoscopic.
This is where the image appears to jump off the screen and typically
requires the viewer to wear special glasses. The technology has been
around for a while (since the 1800s, actually!) but has recently gained
popularity with theatrical movie releases and even sporting event
broadcasts.
How is the content produced?
One way to create stereoscopic images is to use 3-D computer graphics.
Most 3-D software packages have the ability to set up a stereoscopic
camera (see coffee cup below).
Stereoscopic video is recorded either with two cameras side-by-side or a
special camera with two lenses. These two lenses capture the image at
different horizontal positions, roughly the same distance apart as the
human eyes, creating a parallax (or displacement) between the two
images. Objects closer to the camera will have greater displacement
among the two images.
To illustrate this, hold up a finger about two inches from your nose and
alternate closing each eye quickly. You'll notice the location of your
finger appears to jump between the two views. Now, move it arms-length
away and do the same. The apparent location of your finger won't change
as drastically. 3-D cameras capture images just like human eyes!
How is it viewed?
To view a stereoscopic image, the captured left/right images need to be
projected to the appropriate eye. This is usually done through the use
of glasses. There are many types of 3-D glasses; some of the most common
ones are:
Passive/Complementary color anaglyph – This is the typical red/cyan
glasses you got with comic books. The colored lenses filter out the
opposite side so each eye only sees the part of the image intended for
that eye. So if the right-side image is tinted red, the left lens is
red, which blocks out the image on the right. The downside of this
method is it sacrifices color quality.

regularly. Video is becoming a valuable tool for business promotion and
it’s important to be familiar with the camera. If you have been asked
to represent your company through video, here are some tips to make
things go smoothly and ensure that you look your best.
What to say
- Create a bulleted list of talking
points. It may sound easier to write a word-for-word script, but unless
you are an experienced actor or news anchor, it will likely sound
unnatural.
- Prepare for a video shoot as if you are planning to
speak at a meeting or public function. Talk naturally as if speaking to a
colleague or client.
