720p vs. 1080p vs. 4K resolution: Does it really make a difference?

720p vs 1080p vs 4K Resolution

I know that many of you out there are shouting at your computer screens after reading that headline. "Of course it makes a difference!" And you're right — there is a perceptible difference between the most common resolutions for TVs, smartphones and computer monitors. But your mileage will noticeably vary based on a few important factors.

Skype for iPad & iPhone updated with HD video calls, improved call quality

Skype-iPad-video-calls

Update: The iPhone version of Skype just received the same update with HD video calling support on iPhone 5.

Today Skype updated its iPad app with the ability to make HD quality video calls in addition to several other performance improvements. It’s a feature that’s been available on other platforms for quite sometime, including the Mac client, but today the higher quality video calls finally make their way to the latest iPad. Earlier this year Skype rolled out HD video calling to Windows Phone device’s and noted it would include “720P HD on higher-end devices.” We’d imagine that’s also the case with today’s iPad update but, as always, the quality of video will also depend on the quality and bandwidth of your internet connection.

The HD video calling feature is only available on iPad 4, and version 4.10 also brings enhancements to call quality and stability. It also includes “a redesigned country code picker on the dial pad.”

What’s New in Version 4.10

Call quality improvements
- Make HD quality video calls from your iPad 4.
- General improvements to call quality and stability.

General fixes and improvements
- A redesigned country code picker on the dial pad.

Seagate Ships World’s First 4TB HD With Four 1TB Platters

seagate 4tb

Seagate will be shipping a 4TB hard drive that has the distinction of being the world’s first to include a 1TB per platter design. This basically means that each spinning disk in the hard drive has a capacity of 1TB, and that there are four of them.

It’s not everyday that you can claim to that have something that’s the “world’s first”, so don’t be too hard on Seagate.

This certainly isn’t the first hard drive to have a 4TB capacity, but apparently the new 1TB per platter design significantly increases the hard drive’s performance over the competition. It consumes 35 percent less power than comparable drives on the market with 4TB capacities, and at 145MB/s, it has the highest average data rate as well.

But most importantly, the new design will also bring down costs. A hard drive in an external casing can be had for $212, while just the bare drive will cost around $190.

Bring on the terabytes, Seagate. My body and my illegally downloaded movies are ready.

Canon’s New Full-Frame Video Sensor Can Shoot Clear HD Footage In Exceptionally Low Light

Screen Shot 2013-03-04 at 8.04.24 AM

Canon today announced the successful creation of a new full-frame CMOS sensor, designed exclusively for shooting video. The new sensor can capture full-HD video with extremely low noise in settings where it has been hard for traditional cameras to even operate at all in the past. The sensor will have immediate benefits for astrophotography and for use in security systems, but the developments here could eventually help improve the quality of professional and consumer cameras, too.

The new sensor from Canon features large pixels, each of which measure around 7.5x those found on the sensor Canon uses in its EOS-1DX DSLR. The larger pixels are paired with new noise reduction technologies that counteract the added noise effect of using larger pixels, which allows for full HD video shooting in environments as dark as an outdoor setting with just a crescent moon providing illumination. That means it can capture video with fully visible objects even in situations where the human eye would be hard-pressed to make out any definite shapes.

Canon has already built a prototype device to test out the new sensor, and captured things like footage from a room where only lit incense sticks provided any light, the Geminid meteor shower and other night sky scenes. The prototype would be most useful in the immediate future for astronomical and nature photography, medial research and security implementations, but through “further development,” Canon imagines similar CMOS sensor tech will also be able to greatly improve other more creative pursuits.

Low light video is already an impressive feature of full-frame DSLR cameras, but a sensor like this that takes things to the extreme could take nighttime video capture to a whole new level. Imagine greatly reducing the cost of filming at night, for instance, or, depending on how things progress, bringing similar improvements to mobile and smartphone shooters. We’re still a long way off from that, but this is a very impressive first step, as you can see from the sample video available on Canon’s own site.
