Is 4k Video Downloader Safe To Use
With the add-on of 4K video recording on smartphones like the iPhone 6s and Samsung Galaxy S6 this year, many consumers have been left wondering what all the fuss is nearly. What makes a 4K video and so much better than 1080p, and how is the photographic camera on the back of an iPhone any different from a 4K camcorder from Sony or Nikon?
Every bit 4K televisions start to make their manner off the show floor of CES and into our living rooms, here's everything yous'll need to know to be sure your side by side home video looks and acts the part.
What Is "4K" Anyhow?
To start, information technology helps to know what the departure is between 4K video and a standard 1080p recording, and why all 4K isn't created the same.
The same manner "HD" is thrown around to include everything from 720p to 1080p, the concept of what makes "4K" truly 4K can vary depending on the device you're talking about, and the quality of the input/output format.
Right now, at that place are two types of 4K recording formats: UHD 4K (Ultra High-Definition), and DCI 4K (Digital Cinema Initiatives). The first is defined as any recording that takes place at a resolution of 3840 x 2160 (exactly two times the width and height of 1920 x 1080, or 1080p) in the aspect ratio of 16:9, while the 2d packs in slightly more pixels at a resolution of 4096 10 2160, with an aspect ratio of 19:10.

Technically, DCI 4K is the only "true" 4K format, established by a consortium of the top moving-picture show studios as the standard in 4K recording and projection. But UHD 4K is primarily tailored to consumers, since information technology more than accurately fits into the 16:ix attribute ratio that most all televisions and computer monitors use. Digital projectors in a theater, withal, are able to fit the DCI 4K nineteen:10 ratio on their screens without a problem.
For the sake of this article, yous'll simply need to know that consumer camcorders and the cameras on newer smartphones record in the resolution of "UHD 4K", while professional person models are capable of recording at the total DCI 4K spec.
4K Cameras: A Breakdown
The field gets muddy even farther when you offset diving into the different types of 4K cameras out at that place.
To make things a bit simpler, we're going to separate the technology into iii distinct categories: consumer, prosumer, and professional. The first is easily the most common of the lot, as these are the 4K cameras you'll detect on the back of recent smartphones like the iPhone 6s and Samsung Galaxy S6, every bit well every bit certain high-end GoPros. Most of these styles of camera actually record at the UHD specification rather than "truthful" 4K, mostly due to the fact that UHD is natively compatible with the aspect ratio of 1080p displays and consumer-course 4K theater setups.
Next, at that place's prosumer 4K camcorders, which on their own tin can price anywhere from about $700 all the way upward to $5,000, depending on the model you cull. These are personal, handheld camcorders that look about identical to the same camcorders people have been using for years, admitting with huge sensor and lens upgrades. Many newer DSLRs with 4K video recording capabilities can as well be folded into this category, though it'due south important to note that well-nigh DSLRs are normally intended for withal pictures first, with 4K recording capabilities beingness added on as an afterthought.
Final, there's professional person 4K cameras, all-time evidenced by units like anything in the RED lineup of shooters. These cameras are priced manner out of a regular customer's upkeep, costing at a minimum $fifteen,000, all the way up to $250,000 for the deluxe models. These are the cameras that have come to dominate Hollywood since David Fincher'sThe Social Networkbecame the first picture to shoot entirely on 4K back in 2010, and are known primarily for their customization between hundreds of dissimilar additional lenses and professional lighting setups.
But if they all shoot 4K video just the same as the adjacent, why is in that location such a massive gap in price between each tier?
Information technology All Comes Down to Accessories
To go on things brief: information technology's about the add-ons.
At present, when we say "add together-ons", we aren't talking specifically about accessories similar a camera strap or a tripod, but more the different types of lenses, lights, and audio recording equipment that a camera is compatible with. The more than compatible parts, the more versatile the photographic camera is in dissimilar situations.

While prosumer cameras like the Sony A7Rii can support a wide array of lenses that tin change an paradigm drastically (a telephoto lens volition produce something dissimilar than a wide-bending, for instance), 4K smartphones are limited by their size and what types of recording equipment can actually plug into the devices to affect how a shot eventually turns out.
In collections of diverse tests gathered from around the spider web, users have found that in purely stock shots with no added lenses, the iPhone was able to hold its ain against prosumer cameras that were over three times the price. The phone did struggle in lower lighting situations, however, where cameras like the A7Rii were yet able to capture enough of the picture using customized settings. And with the ability to add more lenses, the A7Rii is clearly the more than powerful camera. Only for the average user, the 4K footage from the 6s was nonetheless miles beyond what you would expect out of such a pocket-sized device.
Discussing the difference between a 4K smartphone camera and a $15,000 RED is a whole different ball game. Even though both share similar specs like a 12-megapixel sensor that lets in the aforementioned amount of light and captures the same corporeality of color, the backend processing power of a Ruby allows the operator to shoot 4K video at a much higher framerate. And then while the iPhone 6s is express to only xxx frames per second (a shine recording that can sometimes look jittery if you pay close enough attention), a top end RED will amp that number to upwards of 155fps, at least in the case of its latest "Dragon" sensor.
A higher framerate is necessary when shooting big-upkeep films, because the increased amount of information between each individual frame makes it easier to add in visual effects that lucifer upward with the source format. If you're only using your phone to take some holiday videos though, the deviation is more often than not negligible.
Unless you'rereally into the idea of getting the best possible lighting and sound for your child'south next dance recital, the 4K recording y'all go out of a smartphone will be just as good as what you'd accomplish with a prosumer camcorder that's three times the price. And while neither could hold a candle to the framerates that professionals in Hollywood are using for the side by side Michael Bay blockbuster, they're notwithstanding plenty capable enough to handle everyday recording without a hitch.
